Abstract: Cerebrovascular accident or stroke is the second largest disease in mankind. Sitting balance was always found impaired in stroke patients, and this impairment affected many functional activities severely in daily living. Therefore, sitting balance training was always selected to be a priority in rehabilitation. This study aimed at investigating the effectiveness of the visual biofeedback training in addition to the Occupational Therapy training in stroke patients. Thirteen subjects participated in this study. Seven of them were assigned to the experimental group and six were assigned to the control group by random assignment. There were six males and one female in the experimental group, four male participants were suffered from left hemiplegia and others were right hemiplegia. Their age were ranged from 65 to 82 years old, mean age was 72.14 (SD 5.43). For the control group, there were four males and two females participants, two males and one female were left hemiplegia and the rest were right hemiplegia. Their age were ranged from 72 to 85 years old, mean age was 79.5 (SD 5.40). A visual biofeedback training program was given to participants in the experimental group in addition to their daily training program. Participants were instructed to perform seated weight shifting movement. Visual biofeedback training on center of gravity movement was given to this group of participants. The training duration was 15 minutes per session per day and continued for 10 sessions. In control group, participants were given one 15 minutes Occupational Therapy tainting activity instead. Both groups had four training activities on each day. A pressure measurement system was adopted to evaluate their sitting balance. Five parameters were adopted to evaluate the effectiveness of the training. They were deviation angle of the center of pressure, area of the center of pressure, velocity of the center of pressure, displacement of the center of pressure and the pressure of the ischial tuberosities of the affected and non-affected side. The results indicated that sitting balance was improved in both the control and the experimental groups. However, patients with visual biofeedback training did show additional improvement of weight shifting control in anterior posterior direction.
