Biofeedback eletromiográfico como coadjuvante pode ajudar a manter os resultados da terapia profilática de deglutição em longo prazo na doença de Parkinson? Um estudo piloto / Can adjunctive electromyographic biofeedback help maintain long-term prophylactic swallowing therapy results in Parkinson's disease? A pilot study

RESUMO Objetivo Este estudo piloto teve como objetivo verificar a influência do uso do biofeedback EMG como método coadjuvante para auxiliar na manutenção dos resultados a longo prazo da terapia da deglutição em idosos com doença de Parkinson em uma abordagem profilática. Métodos Os sujeitos foram avaliados quanto ao nível de ingestão oral (Functional Oral Intake Scale - FOIS), qualidade de vida (questionário SWAL-QOL) e videofluoroscopia da deglutição das consistências sólida, pudim e líquida. A gravidade da disfagia foi avaliada por meio do Dysphagia Outcome and Severity Scale (DOSS). Todos os procedimentos foram realizados antes, após três meses e após seis meses do tratamento fonoaudiológico para disfagia orofaríngea. Resultados Três sujeitos foram tratados com terapia fonoaudiológica profilática e três com terapia convencional fonoaudiológica profilática utilizando biofeedback EMG coadjuvante em um total de 18 sessões. Seis pacientes apresentaram melhora nos níveis de ingestão oral, gravidade da disfagia e qualidade de vida após o programa de reabilitação. O nível de ingestão oral foi mantido seis meses após a terapia convencional para dois pacientes e todos os participantes tratados com biofeedback EMG. Conclusão Ambas as modalidades de terapia profilática mostraram melhora na qualidade de vida, nível de ingestão oral e gravidade da disfagia, mas os benefícios foram mantidos ao longo do tempo apenas para os participantes do grupo experimental.

ABSTRACT Purpose This pilot study aimed to verify the influence of using EMG biofeedback as an assisting method to maintain long-term results for swallowing therapy in older adults with Parkinson's disease in a prophylactic approach. Methods: Subjects were evaluated as to the oral intake level (Functional Oral Intake Scale - FOIS), quality of life (SWAL-QOL questionnaire), and videofluoroscopy of swallowing of solid, pudding and liquid consistencies. The severity of dysphagia was assessed using the Dysphagia Outcome and Severity Scale (DOSS). All procedures were performed before, after three months, and after six months of speech-language therapy treatment for oropharyngeal dysphagia. Results: Three subjects were treated with prophylactic speech-language therapy, and three with prophylactic speech-language conventional therapy using adjunctive EMG biofeedback in a total of 18 sessions. Six patients experienced a reduction of the severity of the dysphagia, improved oral intake levels and quality of life after the rehabilitation program. The oral intake level was maintained six months after conventional therapy for two patients and for all participants treated with EMG biofeedback. Conclusion Both therapy modalities with PSLT showed improved quality of life, oral intake level, and reduction of the severity of dysphagia, but the benefits were maintained over time only for participants in the experimental group.

Biofeedback therapy combined with diet to treating ODS (Anismus): 2 years outcome / Terapia por biofeedback combinada com dieta no tratamento da SDO (Anismus): desfecho de 2 anos

ABSTRACT Object: The advantages of biofeedback therapy along with diet in patients with constipation are among the issues discussed nowadays. The aim of this study was to evaluate 2 years outcome of biofeedback therapy along with diet in patients with obstructed defecation syndrome (ODS) (Anismus). Methodology: The focus of this prospective study is a group of 129 patients with ODS constipation, who were referred to two tertiary-care referral academic centers from 2013 to 2016. Patients received biofeedback therapy combined with appropriate diet in cases group and received diet in controls group. Good response was defined as a subject with at least 50 percent improvement from before to after biofeedback therapy on a Cleveland Clinic Florida Constipation Scoring System (CCF). Factors associated with better outcome were analyzed using SPSS 20 software. Results: Out of the 129 patients, 112 patients (86.8%) were female. The mean age of patients was 42.44 ± 15.05 years. The mean CCF score of the patients before and after biofeedback therapy was 12.41 ± 4.39 and 6.00 ± 3.28 respectively in case group (p-value < 0.001). In addition, the mean CCF score of the patients before and after diet therapy was 12.82 ± 4.85 and 9.43 ± 3.79 respectively in control group (p-value < 0.001). While CCF score in both case and control groups reduced significantly after therapy, the rate of this reduction was higher in case group (p < 0.001). Conclusion: Our findings suggest that biofeedback therapy combined with diet will improve patients outcome in ODS constipation. Prospective clinical trials with larger sample sizes are recommend allowing for causal correlations.

RESUMO Objetivo: As vantagens da terapia por biofeedback, juntamente com a dieta, em pacientes com constipação se situam entre os tópicos atualmente em discussão. O objetvo desse estudo foi avaliar os resultados, após 2 anos, da terapia por biofeedback associada à dieta em pacientes com síndrome da defecação obstruída (SDO) (Anismus). Metodologia: O enfoque desse estudo prospectivo é um grupo de 129 pacientes com constipação por SDO, encaminhados a dois centros acadêmicos de referência para atendimento terciário entre os anos de 2013 e 2016. Os pacientes receberam terapia por biofeedback em combinação com dieta apropriada no grupo de estudo (casos), e apenas dieta no grupo de controle. Boa resposta foi deinida como o paciente com pelo menos 50% de melhora desde antes até após a terapia por biofeedback, com o uso de um Sistema de Pontuação para Constipação do Centro Médico Cleveland Clinic Florida (CCF). Os fatores associados a melhor desfecho foram analisados com o uso do programa SPSS 20. Resultados: Dos 129 pacientes, 112 (86,8%) eram mulheres. A média de idade dos pacientes era de 4244 ± 15,05 years. O escore CCF médio dos pacientes antes e depois da terapia por biofeedback foi 12,41 ± 4,39 e 6,00 ± 3,28 respectivamente no grupo de casos (P < 0,001). Além disso, o escore CCF médio dos pacientes antes e depois da dietoterapia foi 12,82 ± 4,85 e 9,43 ± 3,79 respectivamente no grupo de controle (P < 0,001). Embora o escore CCF tanto no grupo de casos como no grupo de controle tenha apresentado redução significativa após a terapia, o grau dessa redução foi mais elevado no grupo de casos (P < 0,001). Conclusão: Nossos achados sugerem que a terapia por biofeedback em combinação com a dieta melhora o resultado para os pacientes apresentando constipação por SDO. Recomendamos a realização de estudos clínicos prospectivos com amostras mais expressivas, que permitam o estabelecimento de correlações causais.

Efeito da terapia vocal associada ao biofeedback eletromiográfico em mulheres com disfonia comportamental: ensaio clínico randomizado, controlado e cego / Effect of vocal therapy associated with electromyographic biofeedback in women with behavioral dysphonia: randomized controlled blinded clinical trial

Introdução: as disfonias podem acometer o nível respiratório, glótico e ressonantal/articulatório, limitar a eficiência da comunicação e gerar prejuízos na qualidade de vida. Quando a etiologia da disfonia está relacionada ao uso vocal incorreto, elas são classificadas como comportamentais. Apesar da literatura mostrar a efetividade de alguns métodos e programas de reabilitação vocal, poucos exploram a autopercepção corporal e a participação da musculatura corporal no quadro da disfonia. A fim de melhorar essas questões, a literatura propôs o biofeedback eletromiográfico. Estudos que analisaram esse método são antigos e apresentam heterogeneidade metodológica, o que dificulta sua reprodução. Dessa forma, é necessário analisar o efeito do método por meio de um ensaio clínico para se obter evidências científicas sobre a intervenção para respaldar a prática clínica baseada em evidências. Objetivo: analisar a efetividade e a duração dos efeitos da terapia vocal associada ao biofeedback eletromiográfico em mulheres com disfonia comportamental. Delineamento do estudo: ensaio clínico, randomizado, controlado e cego. Método: participaram do estudo 22 mulheres (idades entre 18 e 45 anos) com diagnóstico de disfonia comportamental, alocadas de forma randomizada em dois grupos: Grupo Experimental (GE) ­ 11 mulheres que realizaram terapia vocal associada a aplicação do biofeedback eletromiográfico nos músculos esternocleidomastoideo e supra-hioideos; Grupo Placebo (GP) ­ 11 mulheres que realizaram terapia vocal associada a aplicação do biofeedback eletromiográfico placebo. Ambos os grupos realizaram 8 sessões de terapia, duas vezes por semana, com duração de 30 minutos. A terapia vocal de ambos os grupos foi composta por exercícios de trato vocal semiocluído (vibração, humming e fricativo). As avaliações foram realizadas em três momentos: antes, imediatamente após, depois de um e três meses da intervenção fonoaudiológica, e constaram de: avaliação vocal (perceptivo-auditiva e acústica), avaliação eletromiográfica de superfície, autoavaliação vocal, de sintomas vocais e laríngeos, da dor musculoesquelética e da qualidade de vida em voz. Os dados foram analisados estatisticamente, comparando-se os grupos e os momentos de avaliação (p=0,05). Resultados: A terapia vocal proposta promoveu resultados positivos na qualidade vocal, nos sintomas vocais, na qualidade de vida relacionada à voz e na atividade elétrica muscular durante o repouso em mulheres com disfonia comportamental, com ênfase nos aspectos fonatórios e comportamento vocal em nível glótico. Já o biofeedback eletromiográfico promoveu resultados positivos na atividade elétrica muscular durante as tarefas fonatórias e na dor musculoesquelética em mulheres com disfonia comportamental, com base nos aspectos comportamentais e musculares da região extrínseca da laringe, cintura escapular e cervical. Conclusão: Conclui-se que a terapia vocal associada ao biofeedback eletromiográfico tem efetividade equivalente e efeitos que se mantém pelo mesmo tempo na laringe, na voz e na autopercepção de sintomas e da qualidade de vida em voz, e é mais efetiva e tem efeitos que se mantêm por mais tempo na atividade elétrica muscular e na autopercepção da dor musculoesquelética de mulheres com disfonia comportamental do que a terapia vocal realizada de forma tradicional.(AU)

Introduction: dysphonia can affect the respiratory, glottic and ressonantal/articulatory levels, this limits the efficiency of communication and can cause quality of life damages. When the etiology of dysphonia is related to incorrect vocal use, it is classified as behavioral. Although the literature shows the effectiveness of several methods and programs of vocal rehabilitation, few investigate the self-perception and the participation of the body musculature in the dysphonia. In order to improve these issues, the literature proposed the electromyographic biofeedback. The studies that analyzed this method are remote and have methodological heterogeneity which makes it difficult to reproduce. Thus, it is necessary to analyze the effect of the method through a clinical trial to obtain scientific evidence on the intervention to support evidence-based clinical practice. Purpose: to analyze the effectiveness and duration of the effects of vocal therapy associated with electromyographic biofeedback in women with behavioral dysphonia. Study design: randomized controlled blinded clinical trial. Methods: Twenty-two women (18 to 45 years) with a diagnosis of behavioral dysphonia were randomly divided into two groups: Experimental Group (EG) - 11 women participated in vocal therapy associated with the application of electromyographic biofeedback of the sternocleidomastoid and supra-hyoids muscles; Placebo Group (GP) - 11 women participated in vocal therapy associated with the application of placebo electromyographic biofeedback. Both groups performed eight therapy sessions, twice a week, lasting 30 minutes. The vocal therapy of both groups was composed of semioccluded vocal tract exercises (trill, humming and fricative sounds). The evaluations were performed at four time points: before, after, one and three months after the vocal therapy and will consist of the assessments: vocal (auditory-perceptual and acoustic evaluation), surface electromyographic, vocal self-assessment, vocal and laryngeal symptoms, musculoskeletal pain and quality of life in voice. The data were analyzed statistically comparing the groups and the time of evaluation (p0.05). Results: The proposed vocal therapy promoted positive results in vocal quality, laryngeal and vocal symptoms, voice-related quality of life and muscular electrical activity during rest in women with behavioral dysphonia for both groups. Electromyographic biofeedback promoted additional positive results in muscle electrical activity during phonatory tasks and musculoskeletal pain in women with behavioral dysphonia. These results are based on the behavioral and muscular aspects of the extrinsic region of the larynx, scapular and cervical muscles. Conclusion: in this study, the vocal therapy associated with electromyographic biofeedback had equivalent efficacy to traditional therapy in the larynx, voice and self-assessment of symptoms and quality of life. The biofeedback was more effective than traditional therapy on muscular electrical activity and self-perception of musculoskeletal pain and had effects that remained for a longer time in women with behavioral dysphonia.(AU)

Enfermedad de hirayama en un adolescente / Hirayama disease observed in an adolescent

La Enfermedad de Hirayama -o amiotrofia monomélica- es una afección de baja frecuencia y escasamente reportada en la edad pediátrica. Se presenta el caso clínico de un adolescente de 15 años de edad con disminución de la fuerza muscular y pérdida de la masa muscular, que comenzó a los 10 años de edad por la mano izquierda, y le afectó posteriormente el antebrazo. Mantuvo un curso progresivo durante 3 años, para luego mantenerse estable. El electromiograma de aguja arrojó lesión de axones motores o motoneuronas dependientes de los miotomas C7-T1, y en menor grado, C5-C6. En la tomografía axial computarizada con contraste endovenoso en marcada flexión cervical, se observó desde C7-T2 una evidente ectasia venosa posmedular asimétrica, predominantemente del lado izquierdo, por congestión del plexo venoso vertebral posterior interno. En este paciente la enfermedad se detuvo espontáneamente, en otros casos es necesario limitar la motilidad de la columna con el uso de un collar cervical, y solo llegar a la cirugía en los casos más severos de evolución rápida.

Hirayama disease or monomelic amyotrophy is a low frequent, barely reported illness at pediatric ages. Here is the clinical case of 15 years-old boy that presented with reduced muscular strength and loss of muscle mass; this condition began at the age of 10 year in his left hand and then affected the forearm. The illness progressed for three years and then remained stable. The needle electromyogram showed a lesion in C7-T1 myotome-depending motor axons or motoneurons and to less extent in those C5-C6 depending ones. The venous contrast computed tomography on a marked cervical cord flexion position; it was observed an evident asymmetric postmedullary vein ectasia from the C7-T2 myotomes, mainly on the left side, caused by the internal posterior vertebral vein plexus congestion. There was spontaneous remission of the disease in this patient, but it is necessary in other cases to limit the cervical cord motility with the use of a collar and to only perform surgery in the most rapidly evolving and severe cases.

Rehabilitación pelviperineal multimodal en pacientes con incontinencia fecal / Multimodal pelviperineal rehabilitation in patients with fecal incontinence

Fecal incontinence (FI) is associated with low self-esteem and quality of life. Nowadays, multimodal pelviperineal rehabilitation (MPPR) has become the preferred treatment. Purpose: To evaluate our results of multimodal pelviperineal rehabilitation (MPPR) in patients diagnosed with fecal incontinence (FI). Methods: Historic cohort study using a prospectively maintained database from patients with FI that underwent MPPR between years 1999 and 2012. FI was classified according to Jorge-Wexner´s scale, at the beginning (Winitial) and the end (Wfinal) of treatment. In July 2013 a survey was carried out to measure follow-up Wexner score (Wfollow-up) and pelvic muscle training. Statystical analysis was performed using Chi square test, Fisher Test, Mann-Whitney and Odds Ratio. Significant p value < 0.05. Results: One hundred and thirteen patients completed treatment, median age 67 years-old (r: 24-91) and 83 percent female. Median scores for Winitial and Wfinal were 9 points (r: 3-19) and 3 points (r: 0-13), respectively (p < 0.001). In July 2013, 68 (61 percent) patients were available for follow-up. Wexner score at the beginning, end and follow-up were as follows: 9 (i: 3-19), 3 (i:0-12) and 4 (i:0-19), respectively. There were significant differences between Winitial and Wfollow-up (p < 0.001), but not between Wfinal and Wfollow-up (p = 0.23). There were 20 patients (29 percent) who kept training their pelvic muscles and 48 (71 percent) who did it very rarely or did not do it at all. It was the latter group who showed an increased risk to obtain worst score in Wfollow-up (OR = 3.89; CI 95 percent: 1.26-11.9; p = 0.0175). Conclusion: FI patients treated with MPPR show good short and long-term results.

Objetivo: Evaluar los resultados de la RPPM en pacientes con IF. Método: Estudio de cohorte histórica de pacientes con IF que recibieron RPPM entre 1999-2012. Se utilizó la escala de Jorge-Wexner para medir laIF, al inicio (Wi) y fin (Wf) del tratamiento. Se aplicó una encuesta en julio de 2013 para medir el Wexner de seguimiento (Ws) y mantención de ejercicios terapéuticos. Análisis estadístico: prueba de c2, prueba exacta de Fisher, Mann-Whitney y Odds Ratio. Significancia estadística p < 0,05. Resultados: Hubo 113 pacientes que completaron el tratamiento. La mediana de edad fue 67 años (i: 24-91) y 83 porciento género femenino. La mediana de Wi fue de 9 puntos (i: 3-19) y la mediana de Wf fue de 3 puntos (i: 0-13) (p < 0,001). Se logró contactar a 68 pacientes para el seguimiento, en ellos la mediana del puntaje de Wi, Wf y Wsfue de 9 (i: 3-19), 3 (i:0-12) y 4 (i:0-19), respectivamente. Hubo diferencia significativa entre Wi y Ws (p < 0,001), pero no entre Wf y Ws (p = 0,23). Veinte pacientes (29 por ciento) realizaron ejercicios terapéuticos regularmente y 48 (71 por ciento) nunca o raramente; este último grupo es factor de riesgo para obtener peores resultados (OR = 3,89; CI 95 porciento: 1,26-11,9; p = 0,0175). Conclusión: El tratamiento con RPPM en pacientes con IF tiene buenos resultados a corto y largo plazo.

Biofeedback eletromiográfico como coadjuvante no tratamento das disfagias orofaríngeas em idosos com doença de Parkinson / Adjunctive electromyographic biofeedback in the treatment of oropharyngeal dysphagia in elderly with Parkinsons disease

Várias doenças neurológicas que acometem idosos cursam com quadro de disfagia orofaríngea, dentre elas, a doença de Parkinson. Na presença de disfagia orofaríngea neurogênica e mecânica, o biofeedback eletromiográfico (EMG) foi descrito como importante modalidade coadjuvante de tratamento, não tendo sido descrita na literatura a aplicação desse método na reabilitação desta população. O objetivo deste trabalho foi verificar a repercussão ao longo do tempo do uso do biofeedback EMG como método coadjuvante na reabilitação da disfagia orofaríngea em idosos com doença de Parkinson. Seis idosos com doença de Parkinson e com diagnóstico de disfagia orofaríngea submeteram-se à avaliação do nível de ingestão oral com a aplicação da escala funcional de ingestão oral (Functional Oral Intake Scale - FOIS), à avaliação da qualidade de vida por meio da aplicação do protocolo SWAL-QOL, bem como à avaliação videfluoroscópica da deglutição de alimentos nas consistências sólida, pudim e líquida. Para classificação do grau da disfunção da deglutição foi utilizada a escala DOSS, enquanto a escala de Eisenhuber foi aplicada para a análise da estase de alimento em orofaringe. Todos os procedimentos foram realizados antes, após três e seis meses da reabilitação fonoaudiológica. Dos seis indivíduos, três foram reabilitados com terapia convencional e três receberam terapia convencional associada ao biofeedback EMG, num total de 15 sessões (três sessões por semana), seguidas de mais três sessões uma vez por semana para acompanhamento. Para análise estatística foi aplicado o teste de análise de variância de medidas repetidas. Os resultados obtidos mostraram não haver diferença estatisticamente significante para o grau da disfagia entre os grupos reabilitados pelas diferentes modalidades, porém ambos os grupos apresentaram diferença significante (p=0,01) entre os resultados anteriores à reabilitação e após três meses. Não foi encontrada diferença entre os grupos e os períodos avaliados...

Several neurological diseases that affect elderly are related with oropharyngeal dysphagia. Parkinsons disease is one of them. The electromyographic (EMG) biofeedback was described as an important adjunctive method in the treatment of neurogenic and mechanical oropharyngeal dysphagia, but there are few studies about the effectiveness of speech therapy treatment in the rehabilitation of this individuals. The objective of this study was verify the influence over the time of EMG biofeedback as an adjunctive method in the treatment of oropharyngeal dysphagia in elderly with Parkinsons disease. Six elderly with Parkinsons disease and oropharyngeal dysphagia were evaluated for the level of oral intake using the Functional Oral Intake Scale (FOIS), for the quality of life using the SWAL-QOL questionnaire and for videofluoroscopy of swallowing of solid, pudding and liquid consistencies. The severity of dysphagia was obtained using the Dysphagia Outcome and Severity Scale DOSS and the level of food residue in oropharynx was obtained using Eisenhuber scale. All procedures were realized before, after three months and after six months of speech therapy treatment for oropharyngeal dysphagia. From the six individuals, three were treated with conventional therapy for oropharyngeal dysphagia and three were treated with conventional therapy using adjunctive EMG biofeedback, in a total of 15 sessions (three times a week), followed by three sessions (once a week) for maintenance. The statistical analysis used was repeated measures analysis of variance test. The results didnt have significant difference for severity of dysphagia between groups treated with different speech therapy, but had significant difference between the times before and after three months of rehabilitation (p=0.01). For the levels of food residue and oral intake were not seen statistical difference between the groups and the different times. The quality of life assessment showed significant...

Brain stimulation used as biofeedback training for recovery of motor functions deteriorated by stroke / A estimulação cerebral em pacientes com acidente vascular cerebral está associada a melhoria no desempenho motor e a incremento de eficácia na função neuronal

According to World Health Organization, approximately 15 million people are affected by cerebrovascular accident in the world. We study the effect of brain stimulation plus an imaging procedure used as biofeedback training for recovery of motor functions impaired by CVA. Four individuals aged between 33 and 72 years were included in the study, of both genders, with hemiparesis on the left arm due to the CVA. They had their brain activity monitored by EEG. Functional tasks were evaluated according to an observational model proposed by the international classification of functioning and by runtime. The training was composed of 12 sessions of 30 minutes of stimulation by light and sound, as well as imaging procedures. Results revealed that improvements in the performance of the task, with regard to both the runtime and the functional quality of movements, are more related to the increase of effectiveness of neuronal function.

Segundo a Organização Mundial da Saúde, aproximadamente 15 milhões de pessoas no mundo sofrem acidente vascular cerebral (AVC). Estudaram-se os efeitos da estimulação cerebral associada à imagética, como treinamento de biofeedback, para a recuperação das funções motoras deterioradas pelo AVC. Foram incluidos 4 indivíduos com idade entre 33 e 72 anos, de ambos os gêneros, e com hemiparesia no braço esquerdo devido ao AVC. Esses pacientes tiveram a atividade cerebral monitorada por EEG. A tarefa funcional foi avaliada de acordo com o modelo de observação proposto pela Classificação Internacional de Funcionalidade e pelo tempo de execução. O treinamento consistiu de 12 sessões de 30 minutos de estimulação por luz e som associado à imagética. Os resultados revelaram melhoria no desempenho da tarefa, tanto em relação ao tempo de execução quanto à qualidade funcional do movimento, e que está mais relacionada com o incremento de eficácia da função neuronal.

Concurrent validity of the pressure biofeedback unit and surface electromyography in measuring transversus abdominis muscle activity in patients with chronic nonspecific low back pain / Validade concorrente da unidade de biofeedback pressórico e eletromiografia de superfície na mensuração da atividade muscular do transverso abdominal em pacientes com dor lombar crônica inespecífica

BACKGROUND: The Pressure biofeedback unit (PBU) is an assessment tool used in clinical practice and research aimed to indirectly analyze the transversus abdominis (TrA) muscle activity. The concurrent validity of the PBU in a clinically relevant sample is still unclear. OBJECTIVE: The purpose of this study was to evaluate the concurrent validity and diagnostic accuracy of the PBU in measuring TrA muscle activity in patients with chronic nonspecific low back pain. METHOD: This study was performed using a validation, cross-sectional design. Fifty patients with chronic nonspecific low back pain were recruited for this study. To test the concurrent validity both PBU measures (index test) and superficial electromyographic measures (reference-standard test) were compared and collected by a physical therapist in a series of voluntary contraction maneuvers of TrA muscle. RESULTS: Participants were on average 22 years old, weighed 63.7 kilos, 1.70 meters height and mean low back pain duration was 1.9 years. It was observed a weak and non-significant Phi coefficient (r=0.2, p<0.20). With regards to diagnostic accuracy tests, our results suggest a low sensitivity (60%) and specificity (60%) of the PBU. The positive predictive value was high (0.8) and negative predictive value was low (0.2). Conclusions: Concurrent validity of the PBU in measuring TrA muscle activity in patients with chronic nonspecific low back pain is poor given the low correlation and diagnostic accuracy with superficial EMG.

CONTEXTUALIZAÇÃO: A Unidade de Biofeedback Pressórico (UBP) é uma ferramenta de avaliação usada na prática clínica e pesquisa científica para analisar indiretamente a atividade muscular do transverso abdominal (TrA). A validade concorrente da UBP em uma amostra clinicamente relevante ainda não está esclarecida. OBJETIVO: Avaliar a validade concorrente e acurácia diagnóstica da UBP em mensurar a atividade muscular do TrA em pacientes com dor lombar crônica inespecífica. MÉTODO: Este estudo foi realizado usando um delineamento de validação. Cinquenta pacientes com dor lombar crônica inespecífica foram recrutados. Para testar a validade concorrente, ambas as medidas pressóricas (teste índice) e eletromiográficas superficiais (teste padrão de referência) foram comparadas e coletadas por um fisioterapeuta a partir de uma manobra de contração voluntária do músculo TrA. RESULTADOS: Os participantes tinham em média 22 anos, 63,7 kg, 1,70 m de altura, e a duração média de dor lombar era de 1,9 ano. Observou-se um coeficiente Phi fraco e não significativo (r=0,2; p<0,20). Com relação aos testes de acurácia diagnóstica, os resultados sugerem uma baixa sensibilidade (60%) e especificidade (60%) da UBP. O valor preditivo positivo foi elevado (0,8), e o valor preditivo negativo foi baixo (0,2). Conclusões: A validade concorrente da UBP em mensurar a atividade muscular do TrA em pacientes com dor lombar crônica inespecífica é pobre, considerando a baixa correlação e acurácia diagnóstica com a EMG de superfície.

Central Nervous System disorders may cause important functional unbalance in the maintenance of balance and posture. There is no effective rehabilitation for these symptoms until now. OBJECTIVE: The aim of this paper is to evaluate the use of tongue electrotactile stimulation on patients with central imbalance using BrainPort. MATERIALS AND METHODS: This is a prospective case series study. We evaluated 8 patients with central imbalance, 6 men and 2 women, with mean age of 67.75 years. The patients were submitted to Computed Dynamic Posturography (CDP) and then received 18 sessions of electrotactile stimulation by BrainPort® device for 20 minutes, twice a day. Then they were submitted to a new CDP test and to a self-perception scale to assess symptom remission, partial improvement and no improvement at all. RESULTS: 75 percent of the patients reported being more stable. There was no improvement in the balance control of the mass center in these patients. CONCLUSION: The patients were able to use the electrotactile stimulus to improve their balance control.

As lesões do Sistema Nervoso Central (SNC) determinam importantes prejuízos funcionais na manutenção do equilíbrio e da postura. A reabilitação vestibular e a fisioterapia oferecem benefícios limitados nesses casos. OBJETIVO: Avaliar a resposta de pacientes portadores de desequilíbrio de origem central à estimulação eletrotáctil da língua por meio do BrainPort®. CASUÍSTICA E MÉTODO: O estudo é prospectivo e configura uma série de casos. Foram avaliados 8 pacientes portadores de desequilíbrio de origem central, 6 homens e 2 mulheres com média de idade de 67,75 anos. Os pacientes foram submetidos à posturografia dinâmica computadorizada (PDC) e submetidos ao treinamento pelo BrainPort®. em duas sessões diárias de 20 minutos, perfazendo um total de 18 sessões. Foram então reavaliados pela PDC e a uma escala análogo visual, que compreendeu remissão dos sintomas, melhora parcial e sem melhora. RESULTADO: 75 por cento dos pacientes referiram melhora subjetiva. Não houve diferença significante nos parâmetros avaliados da PDC, mas foi observada a melhora do controle postural do centro de massa nesses mesmos pacientes. CONCLUSÃO: Os pacientes puderam utilizar o estímulo eletrotáctil para melhorar o seu controle postural.

Enuresis nocturna y sindrome de disfunción evacuatoria en niños varones: respuesta al tratamiento con biofeedback urinario de vaciado / Nocturnal enuresis and voiding dysfunction syndrome in boys: response to treatment with biofeedback urinary drainage

La enuresis o síndrome de la "cama mojada" representan un porcentaje importante de la consulta diaria del pediatra y del urólogo pediatra. Se estima que entre el 15 y el 20% de los niños a los 5 años de edad mojan la cama (Moffatt 1994). El Síndrome de disfunción evacuatoria se asocia con mucha frecuencia a niñas enuréticas nocturnas. De los niños varones enuréricos un 20.9% presenta además incontinencia diurna y constipación. OBJETIVOS: demostrar que los niños enuréticos que asocian síntomas diurnos de incontinencia y constipación, presentan una incoordinación miccional por hábito retencionista y que mejoran con re-educación miccional mediante biofeedback de vaciado. MATERIAL Y METODOS: se estudiaron 50 niños que asociaban enuresis y síntomas diurnos de inestabilidad vesical y constipación. Fueron tratados mediante biofeedback urinario de vaciado, enseñando a los pacientes a relajar su periné durante la micción. Estadísticamente los resultados se obtuvieron con una alfa de 0.005 y una beta de 0.30. El delta observado en estudios previos fue bastante amplio de que no permitió obtener un power o poder del 70% con el estuido de 50 pacientes. RESUTLTADOS: La enuresis nocturna mejoró un 86%(p=<0,001), la urgencia mejoró del 98% al 8% y la incontinencia diurna paso de 7,22 veces por día a 0,36.(p=<0,001). La constipación mejoró de un promedio de 4,34 deposiciones por semana a 6,44(p=<0,001). CONCLUSIONES: El biofeedback urinario de vaciado resulto útil en el tratamiento de la enuresis y síntomas de vejiga hiperactiva así como de la constipación en niños portadores de síndrome de disfunción evacuatoria. No hubo diferencias significativas entre los resultados obtenidos en las dos primeras semana de tratamiento y al final (7 meses) lo que muestra la persistencia de los resultaods durante este tiempo...

Uso de la técnica de miofeedback orientada en actividades de la vida diaria básicas en personas secueladas de un accidente cerebro vascular / Myofeedback in basic activities daily life in patiens with stroke

El Accidente Cerebro Vascular (ACV) es la segunda causa de muerte en Chile y sus secuelas repercuten en el desempeño ocupacional; 50 por ciento necesita asistencia para bañarse, 30 por ciento para vestirse y 10 por ciento para higiene personal. La recuperación funcional e independencia es el objetivo de la rehabilitación, sin embargo, existe escasa evidencia de técnicas efectivas para usuarios secuelados de un ACV. El Miofeedback se ha dirigido al reaprendizaje de movimientos aislados y repetitivos, por lo tanto este trabajo tiene como objetivo "conocer el funcionamiento motor, ocupacional y de satisfacción de movimientos en usuarios con ACV antes y después de la aplicación de un Programa de Miofeedback orientado en AVDB". El grupo de estudio corresponde 8 personas. Cada uno tuvo 10 sesiones individuales de 60 minutos, 2 veces por semana, usando el miofeedback durante la ejecución de las AVDB. Evaluadores doble enmascarado aplican 5 pautas de evaluación al inicio y al término del Programa. Los participantes logran mejoras estadísticamente significativas en 5 de las 6 pautas, utilizando una prueba no paramétrica (t-student). Según estos resultados el uso de Miofeedback genera cambios significativos en los participantes, permitiendo generar evidencia tanto del uso de la ocupación como medio terapéutico, como de la tecnología al servicio de la rehabilitación.

The Stroke is the second reason of death in Chile and its sequels (motor, cognitive, etc) affect the occupational performance, causing dependence in basic activities of the daily living (BADL): 50 percent needs assistance to washing, 30 percent to dress and 10 percent for personal hygiene. The functional recovery and independence is the aim of the rehabilitation, but there exists scanty evidence of effective techniques for chronic users whit stroke. The myofeedback has gone to the relearning of aislated and repetitive movement, therefore this work has as aim "to know the motor occupational function and satisfaction of movement of stroke patients before and after the application of a Miofeedback's Program, oriented to BADL". The group of study corresponds to 8 persons. Each one had 10 individual sessions of 60 minutes, twice a week, using the Miofeedback during the performance of the BADL. Double blinded apply 5 test; motor, occupational function and satisfaction of movement to initial and final of treatment. Participants achieve statistically significant improvements in 5 of 6 tests, using non-parametric test (t-student). According to these results Miofeedback's use generates significant changes in the participants, allowing to generate evidence both on the use of occupation as a therapeutic means, as on the technology at the service of rehabilitation.

Effect of Biofeedback-assisted Autogenic Training on Headache Activity and Mood States in Korean Female Migraine Patients

Biofeedback with or without combined autogenic training is known to be effective for the treatment of migraine. This study aimed to examine the effect of biofeedback treatment on headache activity, anxiety, and depression in Korean female patients with migraine headache. Patients were randomized into the treatment group (n=17) and monitoring group (n=15). Mood states including anxiety and depression, and psychophysiological variables such as mean skin temperature of the patients were compared with those of the normal controls (n=21). We found greater treatment response rate (defined as > or =50% reduction in headache index) in patients with biofeedback-assisted autogenic training than in monitoring group. The scores on the anxiety and depression scales in the patients receiving biofeedback-assisted autogenic training decreased after the biofeedback treatment. Moreover, the decrease in their anxiety levels was significantly related to the treatment outcome. This result suggests that the biofeedback-assisted autogenic training is effective for the treatment of migraine and its therapeutic effect is closely related to the improvement of the anxiety level.

Manejo de la constipación crónica del adulto: Actualización: [revisión] / Constipation in adults: An update: [review]

Constipation affects 2 percent to 27 percent of individuals. It is associated to irritable bowel syndrome in 59 percent of cases, to a pelvic floor dysfunction in 29 percent and to a low transit time in 13 percent. During assessment of patients with constipation the effects of medications and chronic diseases must be discarded and the ideal is to determine which type of functional disorder it present. An algorithm for the management of chronic idiopathic constipation, that includes a recommendation to increase fiber and liquid intake as an initial approach and an orientation to the use of different laxatives, is presented. The usefulness of biofeedback in patients with pelvic floor dysfunction and without organic cause of constipation, is also discussed.

A therapeutic maneuver for oropharyngeal dysphagia in patients with parkinson's disease

OBJECTIVE: This study investigates resources to provide better conditions for oropharyngeal swallowing for improvement in the quality of life of Parkinson's disease patients. METHOD: Three men and one woman with an average age of 70.25 years had been afflicted with Parkinson's disease for an average of 9.25 years. The patients were submitted to a rehabilitation program for oropharyngeal dysphagia after a clinical evaluation of swallowing. The rehabilitation program consisted of daily sessions for two consecutive weeks during which a biofeedback resource adapted especially for this study was used. The patients were then reevaluated for swallowing ability at follow-up. RESULTS: The patients presenting difficulties with swallowing water displayed no such problems after rehabilitation. Only one patient exhibited slow oral transit of food and other discrete oropharyngeal food remnants when swallowing a biscuit. The sample variance was used to analyze the pressure measurements, demonstrating a numerical similarity of the results obtained with the swallowing of saliva or of biscuits (VAR = 4.41). A statistical difference was observed between the swallowing of saliva and biscuits, showing a significant pressure increase at the end of the rehabilitation program (p < 0.001). CONCLUSION: The effortful swallow maneuver reinforced by using biofeedback appears to be a therapeutic resource in the rehabilitation of oropharyngeal dysphagia in Parkinson's disease patients.

Pelvic Floor Muscle Exercise by Biofeedback and Electrical Stimulation to Reinforce the Pelvic Floor Muscle after Normal Delivery / 간호학회지

PURPOSE: This study was conducted to investigate the effectiveness of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal delivery. METHODS: The subjects of this study were 49 (experimental group: 25, control group: 24) postpartum women who passed 6 weeks after normal delivery without complication of pregnancy, delivery and postpartum. The experimental group was applied to the pelvic muscle enforcement program by biofeedback and electrical stimulation for 30 minutes per session, twice a week for 6 weeks, after then self-exercise of pelvic floor muscle was done 50-60 repetition per session, 3 times a day for 6 weeks. Maximum pressure of pelvic floor muscle contraction (MPPFMC), average pressure of pelvic floor muscle contraction (APPFMC), duration time of pelvic floor muscle contraction (DTPFMC) and the subjective lower urinary symptoms were measured by digital perineometer and Bristol Female Urinary Symptom Questionnaire and compared between two groups prior to trial, at the end of treatment and 6 weeks after treatment. RESULTS: The results of this study indicated that MPPFMC, APPFMC, DTPFMC were significantly increased and subjective lower urinary symptoms were significantly decreased after treatment in the experimental group than in the control group. CONCLUSIONS: This study suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for reinforcing pelvic floor muscle after normal delivery.

Biofeedback treatment of fecal incontinence incorporating a mental variable without instrumentation: a prospective pilot study in Hispanic population / Tratamiento con biofeedback de la incontinencia fecal con incorporación de una variable mental y sin instrumentación: un estudio piloto prospectivo en población hispana

The long-established approaches utilized to treat fecal incontinence always require instrumentation with some type of electronic equipment. This equipment is not always available in every institutions. In addition, no studied protocol principally used as coordination, sensory, or strength training has reached the level of gold standard. The purpose of this study was to describe a simple biofeedback technique that incorporating a mental variable and not requiring electronic equipment with prior adequate training could be used at any medical institution. METHODS: A particular modality of an operant conditioning technique was given once and a home trainer program was established. Forty-eight patients (mean age 37.1 +/- 3.7 years) were recruited. Patients had suffered from total incontinence for a period of 55 +/- 7.5 months, all used two to three pads per day and suffered 2.4 +/- 0.2 episodes of incontinence per day. Patients underwent clinical history recording, laboratory tests, recto-sigmoidoscopy, and double-contrast barium enema. Manometry and rectal sensitivity were performed in 7 and 27 patients, respectively. For physiologic comparisons, 21 healthy volunteers were used. RESULTS: A total of 79.1% of patients became continent in a median period of 3.9 +/- 0.5 months. An average of 3.85 +/- 0.55 sessions was required. Follow-up continued for 3-11 years. Patients with incontinence showed lower basal mean resting pressure, maximum squeeze pressure and rectal sensitivity (p <0. 01) and spontaneous rectoanal inhibitory reflex was absent in 57%. CONCLUSIONS: This biofeedback approach does not employ any type of electronic equipment and can be easily reproduced in any type of medical center. Additionally, this is the first report in which a methodology for biofeedback therapy successfully incorporates a mental variable in addition to sensory and strength training.

Antecedentes: Los tratamientos establecidos para laincontinencia fecal requieren instrumentación conalgún tipo de equipo electrónico. Estos no está disponible en todas las instituciones. Además, ningunoha alcanzado el nivel de gold standard. El propósito de este estudio fue describir una técnica de feedback simpleque, incorporando una variable mental y no requiriendo equipo electrónico, podría ser utilizada en cualquier institución médica con el adecuado entrenamiento. Métodos: Se aplicó una modalidad particular de condicionamiento operativo en una ocasión y un programa de entrenamiento en casa fue indicado posteriormente. Se reclutaron 48 pacientes (edad media 37.1 ± 3.7 años), con incontinencia total durante 55± 7.5 meses, cambios de pañal de dos a tres veces por día, y 2.4 ± 0.2 episodios de incontinencia por día. Seles efectuó historia clínica, laboratorio, rectosigmoidoscopía, y colon por enema de doble contraste. Se efectu-aron manometría y sensibilidad rectal en 7 y 27 pacientes, respectivamente. Para comparaciones fisiológicasón se utilizaron 21 voluntarios sanos. Resultados: Un total de 79% de los pacientes recobraron la continenciaen un período de 3.9 ± 0.5 meses, requiriendo un promedio de 3.8 ± 0.5 sesiones. El seguimiento continuópor 3 a 11 años. Los pacientes con incontinencia mostraron menor presión basal media en reposo, máximasensibilidad rectal (p <0.01) y ausencia del reflejo rectoanal inhibitorio espontáneo en el 57% de los casos.Conclusiones: Este tratamiento de biofeedback no emplea ningún tipo de equipo electrónico y puede serfácilmente reproducido en cualquier centro médico. Adicionalmente, este es el primer reporte en el cual unatécnica de tratamiento con biofeedback incorpora con éxito una variable mental además del entrenamiento sensorial y de contracción.

Management of attention deficit/hyperactivity disorder--use of an effective paradigm.

The management of ADHD poses a great problem before the psychologists, psychiatrists and different behavioural scientists. The multi-model approach, combining pharmacologic with different non-pharmacologic interventions, is more effective than any form of therapy. In the present study the theta feedback, a non-pharmacologic technique, has shown beneficial role among the low medicated ADHD cases. The present study also signifies the role of multi-model intervention in the management of ADHD.
