ABSTRACT

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.

ABSTRACT

ABSTRACT Background: The relationship of bidirectional comorbidity between chronic migraine and pain in the cephalic segment led us to evaluate the improvement in reducing the pain in patients diagnosed with chronic migraine headache and awake bruxism, when undergoing treatment with a partial posterior interocclusal device designed for the management and control of awake bruxism through biofeedback. Methods: Seventy-four patients were evaluated during the following periods: pretreatment, seven, thirty, ninety, one hundred and eighty days, and one year. The evaluation was carried out by measuring the pain in the pretreatment period and pain reduction after awake bruxism treatment, using clinical evaluation and numerical scales for pain. Results: Most of the patients who complained of headache migraine pain, masticatory myofascial pain, temporomandibular joint and neck pain experienced a significant reduction in overall pain, including headaches, between t0 and t30 (p<0.0001). After 30 days of using the device, it was observed that the improvement remained at the same level without any recurrence of pain up to t90. At t180 and t360, it was observed that even with the device withdrawal (at t90) the improvement remained at the same level. Conclusion: The utilization of a posterior interocclusal device designed for the management and control of awake bruxism through biofeedback seems to contribute to the reduction of pain (including migraine headache) in the majority of patients, and, even with the device withdrawal (at t90), the improvement remained at the same level, suggesting the patients succeeded in controlling their awake bruxism and consequently the pains.


RESUMO Introdução: A relação de comorbidade bidirecional entre enxaqueca crônica e dor no segmento cefálico nos levou a avaliar a melhora na redução da dor em pacientes diagnosticados com cefaleia crônica de enxaqueca e bruxismo de vigília, quando submetidos a tratamento com dispositivo interoclusal posterior parcial projetado para o manejo e o controle do bruxismo acordado através de biorretroalimentação (biofeedback). Métodos: Setenta e quatro pacientes foram avaliados durante os seguintes períodos: pré-tratamento, sete, trinta, noventa e cento e oitenta dias, e um ano. A avaliação foi realizada por meio da avaliação da dor no período pré-tratamento e redução da dor após o tratamento do bruxismo de vigília, através de avaliação clínica e escalas numéricas de dor. Resultados: A maioria dos pacientes que se queixou de dor de cabeça com enxaqueca, dor miofascial mastigatória, articulação temporomandibular e dor no pescoço sofreu uma redução significativa na dor geral, incluindo dores de cabeça, entre t0 e t30 (p<0,0001). Após 30 dias de uso do dispositivo, observou-se que a melhora permaneceu no mesmo nível, sem recorrência da dor até t90. Em t180 e t360, observou-se que, mesmo com a retirada do dispositivo (em t90), a melhoria permaneceu no mesmo nível. Conclusão: A utilização de um dispositivo interoclusal posterior projetado para o controle do bruxismo de vigília através de biofeedback parece contribuir para a redução da dor (incluindo enxaqueca) na maioria dos pacientes, e, mesmo com a retirada do dispositivo (t90), a melhora manteve-se no mesmo nível, sugerindo que os pacientes conseguiram controlar o seu bruxismo de vigília e a dor associada a esse hábito.

ABSTRACT

ABSTRACT BACKGROUND: Biofeedback is an effective method of treatment for fecal incontinence but there is controversy regarding factors that may be correlated with its effectiveness. OBJECTIVE: To evaluate the efficacy of biofeedback in the treatment of fecal incontinence, identifying the predictive factors for unsuccessful treatment. METHODS: Consecutive female patients who had fecal incontinence and were treated with a full course of biofeedback were screened. The symptoms were evaluated using Cleveland Clinic incontinence (CCF) score before and six months after the completion of therapy. Patients had a satisfactory clinical response to biofeedback if the CCF score had decreased by more than 50% at six months (GI) and an unsatisfactory response if the CCF score did not decrease or if the score decreased by <50% (GII). The groups were compared with regard to age, score, anal resting and squeeze pressures and sustained squeeze pressure by manometry, history of vaginal delivery, number of vaginal deliveries, menopause, hysterectomy, and previous anorectal surgery. RESULTS: Of 124 women were included, 70 (56%) in GI and 54 (44%) in GII. The median CCF score decreased significantly from 10 to 5 (P=0.00). FI scores were higher in GII. Patients from GII had more previous vaginal deliveries and previous surgeries. The mean sustained squeeze pressure was higher in GI. Patients from GI and GII had similar ages, number of vaginal deliveries, menopause, hysterectomy, anal pressures, and sphincter defects. The median sustained squeeze pressure increased significantly before and after biofeedback in GI. CONCLUSION: Biofeedback therapy shows effective treatment with 50% reductions in FI score in half of patients. Factors associated with unsuccessful outcome include FI score ≥10, previous vaginal delivery, previous anorectal and/or colorectal surgery, and reduced mean sustained squeeze pressure.


RESUMO CONTEXTO: Biofeedback é um método eficaz de tratamento para a incontinência fecal. No entanto, há controvérsias sobre fatores que podem ser correlacionados com a sua eficácia. Objetivo - Avaliar a eficácia do biofeedback no tratamento da incontinência fecal (IF), identificando os fatores preditivos relacionados ao insucesso do tratamento. MÉTODOS: Consecutivos pacientes do sexo feminino com IF e submetidos a terapia com biofeedback que aceitaram participar do estudo foram incluídos. Os sintomas foram avaliados utilizando o escore de incontinência da Cleveland Clinic-CCF antes e seis meses após termino da terapia. Os pacientes com resposta satisfatória ao biofeedback apresentaram redução no escore de IF ≥50% (GI) e resposta insatisfatória a redução no escore de IF <50% (GII) em seis meses. Os grupos foram comparados de acordo com a idade, escore, pressões anais quantificada pela manometria anorretal (repouso, contração e capacidade de sustentação em 30 segundos), parto vaginal prévio, número de partos vaginais, menopausa, histerectomia e cirurgia anorretal e/ou colorretal prévia. RESULTADOS: Total de 124 mulheres incluídas, 70 (56%) em GI e 54 (44%) em GII. A mediana do CCF escore reduziu significativamente de 10 para 5 (P=0.00). FI escore foi mais elevado no GII, assim como foi observado o maior número de mulheres submetidas a partos vaginais e cirurgias prévias. A pressão média de contração foi significante maior no GI. No entanto, idade, número de partos vaginais, menopausa, histerectomia, pressões anais e presença de defeito esfincteriano foram similares nos dois grupos. A pressão média de sustentação mantida por 30 seg aumentou significamente comparando pré com pós biofeedback no GI. CONCLUSÃO: O biofeedback é um tratamento eficaz com redução em 50% no escore de IF em mais da metade dos pacientes. Os fatores associados ao insucesso do tratamento incluem o escore de IF ≥10, parto vaginal prévio, cirurgia anorretal prévia e pressão média de sustentação reduzida.

ABSTRACT

OBJECTIVE: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. METHODS: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. RESULTS: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. CONCLUSION: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

ABSTRACT

PURPOSE: There is no established treatment of choice for low anterior resection syndrome (LARS). To evaluate the efficacy of biofeedback therapy for objective improvement of pelvic function in LARS, we performed the present study. METHODS: The primary endpoint was the change of Wexner score. Consenting patients between 20 and 80 years old with major LARS at least 2 months after sphincter preserving proctectomy for rectal cancer were enrolled. After recommendation of biofeedback therapy, patients who accept it were enrolled in the biofeedback group and patients who refuse were enrolled in the control group. Initial and follow-up evaluations were performed and analyzed. RESULTS: Fifteen and sixteen patients were evaluated in the control group and the biofeedback group, respectively. There was no statistically significant difference of LARS score between both groups. Decrease in Wexner score and increase in rectal capacity were significantly higher in the biofeedback group (odds ratio [OR], 5.386; 95% confidence interval [CI], 1.194–24.287; P = 0.028 and OR, 1.061; 95% CI, 1.002–1.123; P = 0.042). CONCLUSION: Biofeedback therapy was superior for objective improvement of pelvic function to observation in LARS. It can be considered to induce more rapid improvement of major LARS.

ABSTRACT

PURPOSE: This study examined the effects of horse riding simulator exercise on the thickness changes in the transverse abdominis in normal adults. METHODS: Forty-five healthy adults were recruited and randomized to a horseback riding simulation exercise group (n=15), a sling exercise group (n=15), and a trunk stabilization exercise group (n=15). A horseback riding simulator offers the indoor experience of horseback riding and mimics the rhythmic movement of horseback riding, thereby provided a virtual environment, such as riding a real horse on the front screen. The velocity of the horse riding simulator exercise was regulated within the subject's ability to control the exercise on the horse riding simulator. A sling exercise group performed sling exercise under the inspection of the experimenter. In the trunk stabilization exercise group, the subjects were instructed to perform the exercise accurately and pause the session when pain occurred during the intervention. The subjects in each group carried out the interventions three times per week for six weeks. The thickness of the transverse abdominis was measured using a pressure biofeedback unit and the ultrasound. RESULTS: Significant differences in the thickness of transverse abdominis within the groups were observed between before and after the interventions. On the other hand, there were no differences in the parameters among the groups. CONCLUSION: Horse riding simulator exercise can be an alternative to trunk stabilization exercise by increasing the thickness of the transverse abdominis in healthy adults.

ABSTRACT

Constipation is a common functional problem of the digestive system and may occur secondary to diet, drugs, endocrine diseases, metabolic diseases, neurological diseases, psychiatric disorders, or gastrointestinal obstruction. When there is no secondary cause, constipation is diagnosed as functional constipation. The first steps that should be taken to relieve symptoms are diet and lifestyle modifications, and if unsuccessful, laxative therapy should be initiated. If a patient does not respond to laxative therapy, diagnostic anorectal physiological tests are performed, though they are not routinely recommended. However, these tests may be considered earlier in patients strongly suspected to have a defecatory disorder. The revised guideline on the diagnosis and treatment of chronic constipation will undoubtedly aid the individualized management of chronic constipation in clinical practice.

ABSTRACT

OBJECTIVE@#To study the clinical effect of psychological and behavioral intervention combined with biofeedback in the treatment of preschool children with attention deficit hyperactivity disorder (ADHD).@*METHODS@#Sixty children each with inattentive, hyperactive/impulsive or combined type ADHD were enrolled. According to the intervention measure, they were randomly divided into 4 groups: control, psychological and behavioral intervention, biofeedback treatment and comprehensive treatment (psychological and behavioral intervention + biofeedback). Attention concentration time and impulse/hyperactivity and hyperactivity index scores of the Conners Parent Symptom Questionnaire (PSQ) were evaluated after 4 months of treatment.@*RESULTS@#The attention concentration time increased in all types children with ADHD after psychological and behavioral intervention, biofeedback treatment or comprehensive treatment (P<0.05). In children with inattentive ADHD, hyperactive/impulsive ADHD or combined-type ADHD, biofeedback or comprehensive treatment reduced the impulse/hyperactivity index score (P<0.05). In children with inattentive or combined-type ADHD, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P<0.05). In children with hyperactive/impulsive ADHD, biofeedback treatment, psychological and behavioral intervention or comprehensive treatment reduced the hyperactivity index score (P<0.05).@*CONCLUSIONS@#In children with ADHD, psychological and behavioral intervention combined with biofeedback treatment can improve the attention concentration and impulsive/hyperactive and hyperactive symptoms. The treatment strategies are slightly different for children with different types of ADHD.

ABSTRACT

ABSTRACT Objective: To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding. Patients and Methods: The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared. Results: A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05). Conclusions: Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.

ABSTRACT

ABSTRACT Introduction: Fecal incontinence is the involuntary loss of stools and gases, characterized by the inability to keep physiological control of bowel contents. It can negatively affect patients' quality of life. Biofeedback is a therapeutic tool used in the treatment, through the training of the pelvic floor muscles from visual and sound stimuli. Objective: To evaluate the effects of biofeedback in the treatment of female fecal incontinence. Methods: Twenty-three patients with fecal incontinence, diagnosed by clinical evaluation and manometry, and referred for biofeedback treatment, participated responding to the Cleveland Clinic Incontinence Assessment scale, and the Fecal Incontinence Quality of Life Questionnaire to obtain personal data, clinical complaints and incontinence characteristics. Four biofeedback sessions were held once a week. After the protocol, they were reevaluated with anorectal manometry and questionnaires, and they were instructed to daily perform the sphincteric contraction exercises at home. Results: The comparison of the Cleveland Clinic Florida Scoring System and FIQL scores before and after the biofeedback protocol showed a significant decrease (p = 0.0001) in fecal incontinence. The mean anal pressure at rest was 33.3 mmHg before and 49.65 mmHg after biofeedback, while the mean anal pressure of maximal voluntary contraction was 85 mmHg before treatment and 136.65 mmHg after it. Conclusion: Biofeedback is an effective method for the treatment of fecal incontinence, with increased sphincter strength and improved quality of life.


RESUMO Introdução: A incontinência anal é a perda involuntária de fezes e gases, caracterizada pela incapacidade de manter o controle fisiológico do conteúdo intestinal. Pode interferir negativamente na qualidade de vida dos pacientes. Biofeedback é uma ferramenta terapêutica utilizada no tratamento, através do treinamento dos músculos do assoalho pélvico, a partir de estímulo visual e sonoro. Objetivo: Avaliar os efeitos do biofeedback no tratamento da incontinência anal feminina. Metódos: Participaram 23 pacientes portadoras de incontinência anal, diagnosticadas pela avaliação clínica, manométrica e encaminhadas para tratamento com biofeedback, responderam um questionário para obtenção dos dados pessoais, queixas clínicas e características da incontinência, a escala de Avaliação da Incontinência da Cleveland Clinic e o questionário Fecal Incontinence Quality of life. Foram realizadas quatro sessões de biofeedback, uma vez por semana. Após o protocolo foram novamente reavaliadas com exame de manometria anorretal e questionários, foram orientadas a realizar os exercícios de contração esfincteriana diariamente em casa. Resultados: Na comparação dos escores dos questionários Cleveland Clinic Florida Scoring System e FIQL antes e após o protocolo de biofeedback pode-se observar diminuição significativa (p = 0,0001) da incontinência anal. As medias de pressão anal de repouso foi de 33,3 mmHg antes e 49,65 mmHg após o biofeedback, enquanto que a média da pressão anal de contração voluntária máxima foi de 85 mmHg antes do tratamento e 136,65 mmHg após o mesmo. Conclusão: O biofeedback é um método efetivo no tratamento da Incontinência anal, com aumento da força esfincteriana e melhora da qualidade de vida.

ABSTRACT

Abstract Introduction There is evidence that all the complex machinery involved in speech acts along with the auditory system, and their adjustments can be altered. Objective To present the evidence of biofeedback application for treatment of vocal disorders, emphasizing the muscle tension dysphonia. Methods A systematic review was conducted in Scielo, Lilacs, PubMed and Web of Sciences databases, using the combination of descriptors, and admitting as inclusion criteria: articles published in journals with editorial committee, reporting cases or experimental or quasi-experimental research on the use of biofeedback in real time as additional source of treatment monitoring of muscle tension dysphonia or for vocal training. Results Thirty-three articles were identified in databases, and seven were included in the qualitative synthesis. The beginning of electromyographic biofeedback studies applied to speech therapy were promising and pointed to a new method that enabled good results in muscle tension dysphonia. Nonetheless, the discussion of the results lacked physiological evidence that could serve as their basis. The search for such explanations has become a challenge for speech therapists, and determined two research lines: one dedicated to the improvement of the electromyographic biofeedback methodology for voice disorders, to reduce confounding variables, and the other dedicated to the research of neural processes involved in changing the muscle engram of normal and dysphonic patients. Conclusion There is evidence that the electromyographic biofeedback promotes changes in the neural networks responsible for speech, and can change behavior for vocal emissions with quality.


Resumo Introdução Há evidências de que o complexo aparato envolvido no ato da fala, juntamente com o sistema auditivo, e seus ajustes podem ser alterados. Objetivo Apresentar evidências da aplicação de biofeedback (biorretroalimentação) para tratamento de distúrbios vocais, enfatizar a disfonia de tensão muscular. Método Realizou-se uma revisão sistemática nas bases de dados de Scielo, Lilacs, PubMed e Web of Sciences, utilizando a combinação de descritores e admitindo como critérios de inclusão: artigos publicados em revistas com comitê editorial, relatos de casos ou pesquisas experimentais ou quase experimentais sobre o uso debiofeedbackem tempo real como fonte adicional de monitoração de tratamento de disfonia de tensão muscular ou para treinamento vocal. Resultados Trinta e três artigos foram identificados em bases de dados, e sete foram incluídos na síntese qualitativa. O início dos estudos de biofeedbackeletromiográficos aplicados à terapia fonoaudiológica foram promissores e indicaram um novo método que permitiu bons resultados na disfonia de tensão muscular. No entanto, a discussão dos resultados carecia de evidências fisiológicas que pudessem servir de base. A busca por tais explicações tornou-se um desafio para os fonoaudiólogos e determinou duas linhas de pesquisa: uma dedicada à melhoria da metodologia de biofeedbackeletromiográfico para distúrbios da voz, para reduzir as variáveis de confusão e outra dedicada à pesquisa de processos neurais envolvidos na alteração do engrama muscular de pacientes normais e disfônicos. Conclusão Há evidências de que o biofeedback eletromiográfico promove mudanças nas redes neurais responsáveis pela fala e pode mudar o comportamento para emissões vocais com qualidade.

ABSTRACT

ABSTRACT Objective: This study was conducted to evaluate the effects of "biofeedback" (BF), electrostimulation (ES), and of the high-fiber diet associated with behavioral therapy in women with obstructed evacuation and paradoxical puborectalis contraction and to compare the results among these three modalities. Method: Thirty-one women were evaluated who fulfilled the Rome III Criteria, and with an electromanometric test positive for the presence of contraction in the evacuation maneuver. These patients were randomized into three groups: group I - conventional treatment of constipation, group II - conventional treatment of constipation associated with biofeedback and group III - conventional treatment of constipation associated with electrostimulation. At the beginning of this study and after six weeks, subjective and objective parameters of the anorectal function were evaluated using the Wexner constipation scoring system, the Bristol scale, an visual analogical scale, and anorectal electromanometry. Results: All patients demonstrated improvement in bowel satisfaction, stool frequency, effort and feeling of incomplete evacuation, stool-type modifications, and improvement in the quality of life. On examination, there was increased mean pressure of voluntary contraction in group III (p = 0.043), decreased sensitivity threshold in group II (p = 0.025) and III (p = 0.012) and decreased maximum rectal capacity in group II (p = 0.005). Only 19.4% (n = 6) had their dynamic defecation normalized, and 80.6% (n = 25) expressed clinical, non-instrumental, improvement. Conclusion: The conventional treatment of constipation, biofeedback and electrostimulation show a significant subjective improvement in symptoms of obstructed evacuation and in quality of life, regardless of the reversal of the paradoxical puborectalis contraction.


RESUMO Objetivo: Verificar os efeitos imediatos do "biofeedback" (BF), eletroestimulação (EE) e da dieta rica em fibras associada à terapia comportamental em mulheres com sintomas de evacuação obstruída e com contração paradoxal da musculatura puborretal e comparar os resultados entre as três modalidades. Métodos: Foram avaliadas 31 mulheres, que preenchiam os critérios de Roma III e que, ao exame eletromanométrico, apresentaram contração à manobra evacuatória. Essas pacientes foram randomizadas e sorteadas em três grupos: grupo I - tratamento convencional da constipação (TCC), grupo II - TCC associado ao BF, e grupo III - TCC associado à EE. No início do estudo e após seis semanas, foram avaliados os parâmetros subjetivos e objetivos da função anorretal, por meio do sistema de pontuação para constipação de Wexner, escala de Bristol, escala analógica visual e eletromanometria anorretal. Resultados: As pacientes demonstraram melhora da satisfação intestinal, frequência evacuatória, esforço e sensação de evacuação incompleta, modificações do tipo de fezes e melhora da qualidade de vida. Houve aumento da pressão média de contração voluntária no grupo III (p = 0,043), diminuição do limiar de sensibilidade nos grupos II (p = 0,025) e III (p = 0,012) e diminuição da capacidade retal máxima no grupo II (p = 0,005). 19,4% (n = 6) normalizaram a dinâmica evacuatória, e 80,6% (n = 25) expressaram melhora clínica e não instrumental. Conclusão: O TCC, BF e a EE apresentam melhora subjetiva significante dos sintomas da evacuação obstruída e da qualidade de vida, independente da reversão da contração paradoxal da musculatura puborretal.

ABSTRACT

We present a 47-year-old right-handed woman with a 15-year history of writer's cramp who was provided with six sessions of cathodal transcranial direct current stimulation (tDCS) combined with observation of writing actions performed by a healthy subject and electromyographic (EMG) biofeedback training to decrease EMG activities in her right forehand muscles while writing for 30 min for 4 weeks. She showed improvement in dystonic posture and writing speed after the intervention. The writing movement and writing speed scores on a writer's cramp rating scale decreased, along with writing time. Our findings demonstrated that cathodal tDCS combined with action observation and EMG biofeedback training might improve dystonic writing movements in a patient with writer's cramp.

ABSTRACT

PURPOSE: To compare the effects of intra-anal biofeedback (BF) and intra-anal electrical stimulation (ES) on pelvic floor muscles (PFMs) activity, nocturnal bladder capacity, and frequency of wet night episodes in children with refractory primary monosymptomatic nocturnal enuresis (PMNE). METHODS: Ninety children of both sexes aged 8–12 years with refractory PMNE participated in this study. They were randomly assigned to 3 groups of equal number: control group (CON) that underwent behavioral therapy and PFM training, and 2 study groups (BF and ES) that underwent the same program in addition to intra-anal BF training and intra-anal ES, respectively. PFMs activity was assessed using electromyography, nocturnal bladder capacity was evaluated by measuring the first morning voided volume, and a nocturnal enuresis diary was used for documenting wet night episodes before treatment and after 3 months of treatment. RESULTS: After training, all groups showed statistically significant improvements in all measured outcomes compared to their pretreatment findings. The ES group showed significantly greater improvements in all measured outcomes than the CON and BF groups. CONCLUSIONS: Both intra-anal BF training and ES combined with behavioral therapy and PFMs training were effective in the treatment of PMNE, with intra-anal ES being superior to BF training.

ABSTRACT

OBJECTIVE: To investigate the dose-related effect of trunk control training (TCT) using Trunk Stability Rehabilitation Robot Balance Trainer (TSRRBT) in chronic stroke patients with poor sitting balance. METHODS: This was a retrospective study of 38 chronic stroke patients with poor sitting balance that underwent TCT with TSRRBT. The participants were assigned either to the low-dose training (LDT) group (n=18) or to the highdose training (HDT) group (n=20). In addition to the conventional rehabilitation therapy, the LDT group received 5 sessions of TSRRBT intervention per week, whereas the HDT group received 10 sessions of TSRRBT intervention per week. The outcome measures were the scores on the Trunk Impairment Scale (TIS) and its subscales, Berg Balance Scale (BBS), Functional Ambulation Classification (FAC), and the Korean version of Modified Barthel Index (K-MBI). All outcome measures were assessed before the training and at the end of the 4-week training. RESULTS: After the 4-week intervention, TIS, BBS, FAC, and K-MBI scores showed improvement in both LDT and HDT groups. Furthermore, the improvements in TIS scores and its subscales were significantly greater in the HDT group than in the LDT group (p < 0.05). CONCLUSION: TCT using TSRRBT could be an additional treatment for the conventional rehabilitation therapy of chronic stroke patients with poor sitting balance. HDT may provide more beneficial effects on improving patients’ sitting balance than LDT.

ABSTRACT

Anorectal disorders are common and present with overlapping symptoms. They include several disorders with both structural and functional dysfunction(s). Because symptoms alone are poor predictors of the underlying pathophysiology, a diagnosis should only be made after evaluating symptoms and physiologic and structural abnormalities. A detailed history, a thorough physical and digital rectal examination and a systematic evaluation with high resolution and/or high definition three-dimensional (3D) anorectal manometry, 3D anal ultrasonography, magnetic resonance defecography and neurophysiology tests are essential to correctly identify these conditions. These physiological and imaging tests play a key role in facilitating a precise diagnosis and in providing a better understanding of the pathophysiology and functional anatomy. In turn, this leads to better and more comprehensive management using medical, behavioral and surgical approaches. For example, patients presenting with difficult defecation may demonstrate dyssynergic defecation and will benefit from biofeedback therapy before considering surgical treatment of coexisting anomalies such as rectoceles or intussusception. Similarly, patients with significant rectal prolapse and pelvic floor dysfunction or patients with complex enteroceles and pelvic organ prolapse may benefit from combined behavioral and surgical approaches, including an open, laparoscopic, transabdominal or transanal, and/or robotic-assisted surgery. Here, we provide an update on the pathophysiology, diagnosis, and management of selected common anorectal disorders.
