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.
