The Effect of Biofeedback on the Motor– Muscular Situation in Rehabilitation of Stroke Patients

Abstract

Introduction: Stroke is the most common debilitating neurological disease in adults. Therefore, rehabilitation is a major consideration to reduce costs and relief disabilities. Biofeedback, a newly recommended method is claimed to be able to improve the consequences following stroke by enhancing the understanding of the psychological functions of the body. The purpose of this study was to investigate the effects of biofeedback on the motor– muscular situation in balance and ability to walk, muscle stiffness (spasticity), hand muscles strength of stroke patients. Methods: The present study was a randomized clinical trial done in 2016. The participants were randomly divided into 2 groups (case and control group). In the intervention group, biofeedback was performed. The check list of main variables, including balance and ability to walk, muscle stiffness (spasticity) and hand muscles strength was completed by a physician before the intervention and at the end of the intervention (16th session). The statistical analysis was conducted, using SPSS version 13. Results: The mean score of balance in intervention group versus control group showed significant differences. The results showed that by eliminating the effects of muscular strength before the intervention, this variable had made improvements and significant differences in both intervention and control groups after the intervention. Comparison of the average spasticity showed that spasticity evaluation score before and after the intervention revealed no significant difference between the two groups. Conclusion: Biofeedback therapy is a promising treatment modality for improving the motor–muscular situation of patients after stroke.

Jogo Sério para reabilitação do equilíbrio de hemiparéticos por acidente vascular cerebral

“…A redução dos níveis desta variável impacta na independência funcional, à medida que limita a realização das AVDs, estando associada também ao aumento do risco de quedas nestes pacientes 18 . Assim, restaurar a FM tem sido uma meta importante da reabilitação do equilíbrio e da marcha, visto que está relacionada com uma distribuição de peso mais simétrica e com a capacidade de deslocamento de peso 2,19 do equilíbrio e de parâmetros da marcha 25 .…”

“…O Acidente Vascular Cerebral (AVC) é considerado mundialmente como a segunda maior causa de morte 1 e a principal no Brasil, sendo também responsável por elevados índices de morbidades e incapacidades funcionais provisórias ou permanentes. Entre as variadas manifestações clínicas da doença, destaca-se o quadro de hemiparesia que corresponde a perda parcial de força muscular (FM) no hemicorpo contralateral ao hemisfério afetado 2 .…”

“…[ 12 ] In addition, previous studies exhibited that sEMG biofeedback exercise was more effective than conventional physiotherapy. [ 13 , 14 ] For this phenomenon, a probable interpretation is that sEMG biofeedback can effectively promote the accuracy of training. Thus, the sEMG biofeedback training can improve the weak agonist performance more accurately in patients with stroke spasticity, which can better improve its function.…”

Jogo Sério para reabilitação de hemiparéticos por Acidente Vascular Cerebral: impacto na qualidade de vida

“…A hemiparesia trata-se da perda parcial de força muscular (FM) no hemicorpo contralateral ao hemisfério afetado, sendo considerada como o quadro clínico típico da doença (Eichinger et al, 2020), afetando mais de 80% dos pacientes (Najafi et al, 2018). A redução da FM implica em importantes prejuízos funcionais, pois compromete a realização das atividades de vida diárias (AVDs), gerando maior dependência e, consequentemente causando restrições na participação (Bunketorp Käll et al, 2020).…”
