ABSTRACT

Introdução: A eletroestimulação é reconhecida como uma das terapias fundamentais na reeducação esfincteriana e do períneo, ao promover a contração dos músculos e permitir ao paciente tomar consciência de si mesmo. Ela induz a contração dos MAP até o restabelecimento da voluntariedade do comando contrátil e ganho de força muscular, garantindo um bom funcionamento das fibras estriadas do esfíncter uretral externo, proporcionando a continência urinária. Objetivo: Identificar a frequência mais utilizada na eletroestimulação para a recuperação da incontinência urinária de esforço (IUE) em mulheres e homens; verificar a eficácia da eletroestimulação no tratamento da incontinência urinária de esforço. Métodos: Realizou-se uma busca nas bases de dados US National Library of Medicine (Medline), Scientific Eletronic Library Online (Scielo), Physiotherapy Evidence Database (PEDro), Cochrane Library, Lilacs, Web of Science, Scopus, Cinahl e Sport Discus, com os descritores incontinência urinária, eletroestimulação e estimulação elétrica, por experimentos controlados randomizados (ECR). Foram incluídos estudos com pacientes homens e mulheres de qualquer idade com IUE, que foram submetidos a eletroestimulação, selecionados pela escala Jadad e avaliado o risco de viés pela ferramenta da Colaboração Cochrane. Dos estudos foram extraídos a idade e sexo dos pacientes, n dos grupos, frequência utilizada na eletroestimulação, duração da sessão, quantidade de sessões, duração do tratamento, avaliação da IUE e o resultado da IUE. Foi utilizado para avaliar o nível de evidência da metanálise o sistema GRADE. Foram metanalisados 8 estudos utilizando-se o RevMan 5.3. Resultados: A frequência mais utilizada na eletroestimulação foi de 50 Hz em mulheres e em homens. Foram identificados 172 ECR, dos quais 26 ECR foram revisados e 8 ECR foram metanalisados. Seis ECR eram com mulheres e apresentaram heterogeneidade (I2 = 48%), redução da IUE de -12,08 g, IC 95% de -14,08 - 10,08 g, P < 0,00001. Para homens, 2 ECR que apresentaram heterogeneidade (I2 = 0%), redução da IUE de -151,28 g, IC de -236,64 - 65,92 g, P < 0,0005. Conclusão: A frequência mais utilizada na eletroestimulação para recuperar a continência urinária de mulheres com IUE e homens com IU pós-prostatectomia foi a de 50 Hz e se mostrou eficaz na recuperação da continência. Entretanto, recomenda-se atenção em relação aos resultados obtidos com os homens, devido ao muito baixo nível de evidência encontrado. (AU)

ABSTRACT

Stroke is one of the most serious diseases that threaten human life and health. It is a major cause of death and disability in the clinic. New strategies for motor rehabilitation after stroke are undergoing exploration. We aimed to develop a novel artificial neural rehabilitation system, which integrates brain-computer interface (BCI) and functional electrical stimulation (FES) technologies, for limb motor function recovery after stroke. We conducted clinical trials (including controlled trials) in 32 patients with chronic stroke. Patients were randomly divided into the BCI-FES group and the neuromuscular electrical stimulation (NMES) group. The changes in outcome measures during intervention were compared between groups, and the trends of ERD values based on EEG were analyzed for BCI-FES group. Results showed that the increase in Fugl Meyer Assessment of the Upper Extremity (FMA-UE) and Kendall Manual Muscle Testing (Kendall MMT) scores of the BCI-FES group was significantly higher than that in the sham group, which indicated the practicality and superiority of the BCI-FES system in clinical practice. The change in the laterality coefficient (LC) values based on μ-ERD (ΔLC

ABSTRACT

Currently, commercial devices for electrical neural stimulations can only provide fixed stimulation paradigms with preset constant parameters, while the development of new stimulation paradigms with time-varying parameters has emerged as one of the important research directions for expanding clinical applications. To facilitate the performance of electrical stimulation paradigms with time-varying parameters in animal experiments, the present study developed a well-integrated stimulation system to output various pulse sequences by designing a LabVIEW software to control a general data acquisition card and an electrical stimulus isolator. The system was able to generate pulse sequences with inter-pulse-intervals (IPI) randomly varying in real time with specific distributions such as uniform distribution, normal distribution, gamma distribution and Poisson distribution. It was also able to generate pulse sequences with arbitrary time-varying IPIs. In addition, the pulse parameters, including pulse amplitude, pulse width, interphase delay of biphasic pulse and duration of pulse sequence, were adjustable. The results of performance tests of the stimulation system showed that the errors of the parameters of pulse sequences output by the system were all less than 1%. By utilizing the stimulation system, pulse sequences with IPI randomly varying in the range of 5~10 ms were generated and applied in rat hippocampal regions for animal experiments. The experimental results showed that, even with a same mean pulse frequency of ~130 Hz, for neuronal populations, the excitatory effect of stimulations with randomly varying IPIs was significantly greater than the effect of stimulations with fixed IPIs. In conclusion, the stimulation system designed here may provide a useful tool for the researches and the development of new paradigms of neural electrical stimulations.

ABSTRACT

Transcranial direct current stimulation (tDCS) is a brain stimulation intervention technique, which has the problem of different criteria for the selection of stimulation parameters. In this study, a four-layer real head model was constructed. Based on this model, the changes of the electric field distribution in the brain with the current intensity, electrode shape, electrode area and electrode spacing were analyzed by using finite element simulation technology, and then the optimal scheme of electrical stimulation parameters was discussed. The results showed that the effective stimulation region decreased and the focusing ability increased with the increase of current intensity. The normal current density of the quadrilateral electrode was obviously larger than that of the circular electrode, which indicated that the quadrilateral electrode was more conducive to current stimulation of neurons. Moreover, the effective stimulation region of the quadrilateral electrode was more concentrated and the focusing ability was stronger. The focusing ability decreased with the increase of electrode area. Specifically, the focusing tended to increase first and then decrease with the increase of electrode spacing and the optimal electrode spacing was 64.0-67.2 mm. These results could provide some basis for the selection of electrical stimulation parameters.

ABSTRACT

Transcranial direct current stimulation (tDCS) is a non-invasive low-current brain stimulation technique, which is mainly based on the different polarity of electrode stimulation to make the activation threshold of neurons different, thereby regulating the excitability of the cerebral cortex. In this paper, healthy subjects were randomly divided into three groups: anodal stimulation group, cathodal stimulation group and sham stimulation group, with 5 subjects in each group. Then, the performance data of the three groups of subjects were recorded before and after stimulation to test their mental rotation ability, and resting state and task state electroencephalogram (EEG) data were collected. Finally, through comparative analysis of the behavioral data and EEG data of the three groups of subjects, the effect of electrical stimulation of different polarities on the three-dimensional mental rotation ability was explored. The results of the study found that the correct response time/accuracy rate and the accuracy rate performance of the anodal stimulation group were higher than those of the cathodal stimulation and sham stimulation groups, and there was a significant difference (

ABSTRACT

Motor imaging therapy is of great significance to the rehabilitation of patients with stroke or motor dysfunction, but there are few studies on lower limb motor imagination. When electrical stimulation is applied to the posterior tibial nerve of the ankle, the steady-state somatosensory evoked potentials (SSSEP) can be induced at the electrical stimulation frequency. In order to better realize the classification of lower extremity motor imagination, improve the classification effect, and enrich the instruction set of lower extremity motor imagination, this paper designs two experimental paradigms: Motor imaging (MI) paradigm and Hybrid paradigm. The Hybrid paradigm contains electrical stimulation assistance. Ten healthy college students were recruited to complete the unilateral movement imagination task of left and right foot in two paradigms. Through time-frequency analysis and classification accuracy analysis, it is found that compared with MI paradigm, Hybrid paradigm could get obvious SSSEP and ERD features. The average classification accuracy of subjects in the Hybrid paradigm was 78.61%, which was obviously higher than the MI paradigm. It proves that electrical stimulation has a positive role in promoting the classification training of lower limb motor imagination.

ABSTRACT

Spinal cord stimulation (SCS) for pain is usually implanted as an open loop system using unchanged parameters. To avoid the under and over stimulation caused by lead migration, evoked compound action potentials (ECAP) is used as feedback signal to change the stimulating parameters. This study established a simulation model of ECAP recording to investigate the relationship between ECAP component and dorsal column (DC) fiber recruitment. Finite element model of SCS and multi-compartment model of sensory fiber were coupled to calculate the single fiber action potential (SFAP) caused by single fiber in different spinal cord regions. The synthetized ECAP, superimposition of SFAP, could be considered as an index of DC fiber excitation degree, because the position of crests and amplitude of ECAP corresponds to different fiber diameters. When 10% or less DC fibers were excited, the crests corresponded to fibers with large diameters. When 20% or more DC fibers were excited, ECAP showed a slow conduction crest, which corresponded to fibers with small diameters. The amplitude of this slow conduction crest increased as the stimulating intensity increased while the amplitude of the fast conduction crest almost remained unchanged. Therefore, the simulated ECAP signal in this paper could be used to evaluate the degree of excitation of DC fibers. This SCS-ECAP model may provide theoretical basis for future clinical application of close loop SCS base on ECAP.

ABSTRACT

Introducción: Los pacientes con diabetes pueden presentar úlceras por presión, independientemente de generar las propias de esta enfermedad. Sin embargo, aunque está entre las probabilidades, es poco frecuente que se genere una úlcera por presión en la región occipital. Objetivo: Presentar un caso en el que se aplicó la estimulación eléctrica en el tratamiento de una úlcera por presión en la región occipital. Presentación del caso: Paciente chilena de 56 años de edad, con antecedentes de hipertensión arterial y diabetes mellitus, no especificada, con cetoacidosis. Se ingresó en la Unidad de Cuidados Intensivos debido a la presencia de dolor abdominal en el hipocondrio derecho, difuso y levemente asociado con un episodio de vómito, y posteriormente sin dolor, pero con sensación de angustia y disnea. La permanencia en cama, casi sin movilidad alguna, provocó la aparición de una úlcera por presión en la región occipital. A pesar de la aplicación de diferentes métodos convencionales, no se lograba mejoría con el tratamiento, por lo que se determinó la aplicación de la estimulación eléctrica, que se realizó durante 42 días, con una sesión diaria de 30 minutos cada vez. Conclusiones: Después de la aplicación del tratamiento con estimulación eléctrica, se logró la cicatrización de la úlcera por presión(AU)


Introduction: Patients with diabetes can present pressure ulcers, apart from the ones generated by this disease. However, although it is within the possibilities, it is not too frequent that pressure ulcer appears in the occipital area. Objective: To present a case in which it was used electric stimulation in the treatment of a pressure ulcer in the occipital area. Case presentation: 56 years old, Chilean, female patient with a background of arterial hypertension and diabetes mellitus, non specified, and with ketoacidosis. She was admitted in the Intensive Care Unit due to the presence of abdominal pain in the right hipochondrium which was diffuse and slightly associated with a vomiting episode, and later, she had no pain but a feeling of anxiety and respiratory distress. Staying in bed, almost without mobility provoqued the onset of a pressure ulcer in the occipital area. In spite of the use of different conventional methods, there was no improvement with those treatments, so, it was decided to use electric stimulation that was carried out during 42 days with a daily session of 30 minutes each time. Conclusions: After the application of the treatment with electric stimulation, it was achieved the healing of the pressure ulcer(AU)

OBJETIVO: Avaliar os efeitos da fisioterapia na incontinência urinária feminina. METODOLOGIA: Tratou-se de uma pesquisa clínica, longitudinal e prospectiva. Participaram do estudo 27 mulheres com idade média de 57,4 anos, com diagnóstico de incontinência urinária, encaminhadas para tratamento em Ambulatório de Fisioterapia Escola. As mesmas responderam um questionário de avaliação dos dados demográficos e clínicos e o questionário de qualidade de vida ICIQ-FS, antes e após intervenção fisioterapêutica por meio de cinesioterapia e eletroestimulação tibial posterior. RESULTADOS: A maioria das mulheres possuía incontinência urinária de esforço (55,6%), sendo que 33,3% (n=9) referiram perdas urinárias de 01 a 04 anos e 33,3 % (n=9) de 04 a 08 anos. A frequência de perdas urinárias antes do tratamento na maioria (55,6%) era diversas vezes ao dia e após o tratamento a maioria (55,6%) perdia uma vez por semana ou menos. Houve diminuição significativa na comparação do ICIQ Score antes e após o tratamento fisioterapêutico (p< 0.0001). CONCLUSÃO: A fisioterapia, por meio de cinesioterapia e eletroestimulação, é eficaz no tratamento da Incontinência Urinária feminina.


Urinary incontinence is defined as any involuntary loss of urine, with females being the most affected. It is classified into three types: stress urinary incontinence; urgency; and mixed. Physiotherapy in the treatment of urinary incontinence consists of normalization of the tone of the pelvic floor muscles, using kinesiotherapy and transcutaneous electrostimulation of the posterior tibial nerve. OBJECTIVE: To evaluate the effects of physiotherapy on female urinary incontinence. METHODOLOGY: It was a clinical, longitudinal and prospective study. The study included 27 women with a mean age of 57.4 years, diagnosed with urinary incontinence, referred for treatment at the School Physiotherapy Outpatient Clinic. They answered a questionnaire to assess demographic and clinical data and the ICIQ-FS quality of life questionnaire, before and after physiotherapeutic intervention through kinesiotherapy and posterior tibial electrostimulation. RESULTS: Most women had stress urinary incontinence (55.6%), and 33.3% (n=9) reported urinary losses from 01 to 04 years and 33.3% (n=9) from 04 to 08 years. The frequency of urinary losses before treatment in the majority (55.6%) was several times a day and after treatment the majority (55.6%) lost once a week or less. There was a significant decrease in the comparison of the ICIQ Score before and after physical therapy treatment (p< 0.0001). CONCLUSION: Physiotherapy, through kinesiotherapy and electrostimulation, is effective in the treatment of female urinary incontinence.

ABSTRACT

Introdução: As alterações motoras e sensoriais da mão diminuem a força dos músculos que compõe esse segmento e pode repercutir na qualidade de vida do indivíduo. No campo da Fisioterapia, a diminuição da força muscular é frequentemente tratada com o emprego de correntes excitomotoras, dentre aquelas comumente empregadas, as correntes russas e Aussie destacam-se por serem de média frequência e promoverem estimulação sensorial confortável. Objetivo: Identificar os efeitos agudos do uso das correntes Aussie e russa sobre a força muscular de flexores de punho e dedos. Métodos: Foi realizado um estudo de caráter experimental, no qual se avaliou a força de preensão palmar antes e após a aplicação de correntes excitomotoras (Aussie e russa). Os voluntários foram divididos em dois grupos, GR, os quais foram submetidos a terapia com corrente russa, e GA, que recebeu a terapia usando a corrente Aussie. A estimulação utilizando a corrente russa foi efetuada com frequência portadora de 2500 Hz com burst de 10 ms, frequência de estimulação de 50 Hz, tempo On 5 segundos e tempo Off 15 segundos e modulação de 20%. Já a estimulação com a corrente Aussie foi realizada com frequência portadora de 1000 Hz com burst de 2 ms, frequência de modulação a 50 Hz, tempo On em 5 segundos, tempo Off 15 segundos, Rampas de subida e descidas fixadas em 2 segundos. Em ambas as estimulações, a intensidade da corrente foi ajustada de acordo com a tolerância do participante, buscando desencadear contração muscular visível, e o tempo total de aplicação foi de 10 minutos. Resultados: As alterações na goniometria e dinamometria foram analisadas por meio de uma ANOVA de dois fatores. Ao analisar os efeitos principais dos dados da goniometria, não foram observadas diferenças estatisticamente significativa entre os grupos [F(2,114) = 2,662; p=0,074] e entre os momentos [F(1,114)= 2,893; p=0,092]. Os dados da dinamometria também não apresentaram efeito principal para os momentos [F(1,114) = 0,392; p=0,533]. No entanto, observou-se efeito principal para grupos com [F(2,114) = 3,119; p=0,048]. Assim, o presente estudo não encontrou diferenças estatísticas significativas no ganho de força de preensão palmar como resultado de uma única aplicação das correntes estudadas. Conclusão: Sugere-se a realização de estudos adicionais utilizando eletroestimulação, buscando estabelecer parâmetros mais indicados para promover maiores ganhos de força muscular e benefícios terapêuticos.

Introduction: The motor and sensorial changes of the strength decrease of the muscles hand can affect the quality of life. In the field of Physical Therapy, the decrease of muscle strength is often treated with the use of excitomotor currents. Among those commonly used, the Russian and Aussie currents stand out because they are of medium frequency and promote comfortable sensory stimulation. Objective: To identify the acute effects of the use of Aussie and Russian currents on the muscular strength of wrist and finger flexors. Methods: An experimental study was carried out, in which the palmar grip strength was evaluated before and after the application of excitomotor currents (Aussie and Russian). The volunteers were divided into two groups, GR, using the Russian current therapy, and GA, who received the Aussie current. The stimulation using the Russian current was performed with carrier frequency of 2500 Hz with burst of 10 ms, stimulation frequency of 50 Hz, time On 5 seconds, time Off 15 seconds and modulation of 20%. The Aussie current stimulation was performed with a frequency of 1000 Hz with a burst of 2 ms, modulation frequency at 50 Hz, time On in 5 seconds, time Off 15 seconds, ramps up and down fixed in 2 seconds. In both stimulations, the intensity of the current was adjusted according to the tolerance of the participant, seeking to trigger visible muscle contraction, and the total time of application was 10 minutes. Results: Changes in goniometry and dynamometry were analyzed using a two-way ANOVA. When analyzing the main effects of the goniometry data, no statistically significant differences were observed between the groups [F (2,114) = 2,662; p = 0.074] and between the moments [F (1.114) = 2.893; p = 0.092]. The dynamometry data also did not present main effect for the moments [F (1,114) = 0.392; p = 0.533]. However, a major effect was observed for groups with [F (2,114) = 3.119; p = 0.048]. Thus, the present study did not find statistically significant differences in palmar grip strength gain as a result of a single application of the currents studied. Conclusion: We suggested to perform additional studies using electrical stimulation, seeking to establish parameters more indicated to promote greater muscle strength gains and therapeutic benefits.

ABSTRACT

ABSTRACT Giovanni Aldini was an Italian physicist interested in propagating Galvanism. With his uncle, Luigi Galvani, he learned techniques of electrical stimulation in humans and helped him to develop them. He later developed his own ideas and created transcranial electric stimulation. This paper presents some of Aldini's personal and professional traits, showing his trajectory and how his performance was important for the development of non-invasive brain stimulation techniques as a whole. Through research on animals and, later, on cadavers, his fundamental discoveries at the beginning of the treatment proposals are used so far.

ABSTRACT

Resumen Introducción El accidente cerebrovascular constituye la principal causa de muerte y discapacidad en Chile. Más del 85% de los pacientes sufren hemiplejía y más del 69% discapacidad motora funcional de las extremidades superiores. Esta alteración genera impacto en el uso de la extremidad superior, afectando las diversas actividades de la vida diaria de las personas. No existen estudios que combinen terapia de biofeedback electromiográfico y activación bimanual con estimulación eléctrica funcional en sujetos secuelados de Accidente cerebrovascular (ACV). Por esto, surge el interés de determinar el efecto que tiene un protocolo de entrenamiento basado en Estimulación Eléctrica Funcional (EEF) con activación bimanual y terapia de biofeedback en la función de la extremidad superior. Metodología: 15 sujetos secuelados de ACV entre 40 y 85 años reclutados en el área de neurorrehabilitación ambulatoria de Clínica Dávila, aleatorizados en un grupo experimental y en dos grupos controles de 5 sujetos. En cada sesión el grupo experimental entrenará quince minutos de activación bimanual con electroestimulación funcional y luego un programa de entrenamiento de biofeedback de diez minutos, mientras que el grupo control 1 y control 2 entrenaron en las mismas condiciones pero con EEF placebo y BF-EMG placebo respectivamente Resultados Existieron cambios significativos en el grupo experimental luego de la intervención. Conclusión Este estudio sugiere la estimulación eléctrica funciona y biofeedback como una herramienta para la rehabilitación de la extremidad superior paréticas en sujetos secuelados de ACV.


Introduction: Stroke is the leading cause of death and disability in Chile. More than 85% of patients suffer from hemiplegia and more than 69% functional motor disability of the upper extremities. This alteration generates an impact on the use of the upper limb, affecting the various activities of people's daily lives. There are no studies that combine electromyographic biofeedback therapy and bimanual activation with functional electrical stimulation in subjects with stroke. Therefore, there is interest in determining the effect of a training protocol based on Functional Electrical Stimulation (FES) with bimanual activation and biofeedback therapy on the function of the upper limb. Methodology: 15 subjects with stroke between 40 and 85 years recruited in the outpatients neurorehabilitation program of Clínica Dávila, randomized in an experimental group and in two control groups of 5 subjects. In each session the experimental group will train fifteen minutes of bimanual activation with functional electrostimulation and then a ten-minute biofeedback training program, while the control 1 and control 2 group trained under the same conditions but with placebo FES and placebo BF-EMG respectively. Results There were significant changes in the experimental group after the intervention. Conclusion This study suggests the electrical stimulation works and biofeedback as a tool for the rehabilitation of the upper limb in subjects with stroke.

ABSTRACT

Abstract Introduction Local anesthesia with sedation has been employed for an increasingly number of otolaryngology procedures, and might be associated with lower surgical morbidity and costs. Facial nerve monitoring is often advisable in otology to minimize the risks of injuries to this cranial nerve, but the principles, techniques and parameters involved have only been studied for procedures under general anesthesia. Objective To report the preliminary outcomes of intraoperative facial nerve moni- toring during otologic procedures under sedation and local anesthesia. Methods A total of five procedures and their respective intraoperative electrophysi- ological main findings were described. Facial neuromonitoring was performed using the same device by an electrophysiologist. The monitor sensitivity was set at 100 mV, and a stimulating probe was used whenever needed. Results Progressively decreasing low-amplitude baseline values were usually obtained as the level of anesthesia increased, with isolated oscillations possibly related to some degree of voluntary muscular activity. These oscillations could be easily distinguished from those of the surgical manipulation or electrical stimulation of the nerve, which tended to be of much greater amplitude and shorter latency, occurring during specific surgical steps. Conclusion With a surgical team with proper procedural knowledge and broad expertise regarding the technique, intraoperative facial nerve monitoring under local anesthesia with sedation seemed both feasible and reliable. Thus, the need for intraoperative neuromonitoring should not be an obstacle for otologic procedures under less aggressive anesthetic management.

ABSTRACT

OBJECTIVE@#To observe the effect of early acupoint electrical stimulation on the decline of lower limbs muscle strength in patients with intensive care unit-acquired weakness (ICU-AW) caused by septic shock.@*METHODS@#A total of 58 patients with ICU-AW caused by septic shock were randomly divided into an observation group (28 cases, 1 case dropped off ) and a control group (30 cases, 2 cases dropped off ). Patients in both groups received routine basic treatment. In the observation group, acupoint electric stimulation therapy was added at Huantiao (GB 30), Futu (ST 32), Zusanli (ST 36), Xuanzhong (GB 39) and Taichong (LR 3). Unilateral point with electrodes were applied, the SDZ-Ⅱ electronic instrument (discontinuous wave, frequency in 2 Hz, strength in 5 mA) was connected and changed to the other side after 30 min of unilateral treatment.The treatment was given 2 times daily, continued for 7 d or until the medical research council (MRC) score being 54 points or more. The changes of lower limb muscle strength MRC score, modified Rankin scale (MRS) score, bilateral quadriceps thickness and gastrocnemius pinnate angle of both groups were observed before treatment and on discharge. The time of admission to ICU, time of hospitalization, mortality during hospitalization, and mortality 28 d after discharge were compared between the two groups. The MRS scores of the two groups were followed up 28 d after discharge.@*RESULTS@#The MRC scores of lower limb muscle strength in the two groups on discharge were higher than those before treatment (@*CONCLUSION@#Early acupoint electrical stimulation can improve the lower extremity muscle decline in patients with ICU-AW caused by septic shock.
