Introducion: The Traumatic brain injury (TBI) is a major cause of disability and motor disorders in adults. Objective: To evaluate the effects of Wii rehabilitation therapy on COP displacement of hemiplegic individuals due to traumatic brain injury. Methods: 10 hemiplegic individuals after TBI were recruited for this study. Mean age, height and weight were 31.3 ± 2.9 years, 1.72 ± 0.03 m and 74.5 ± 5.1 kg, respectively. The individuals were evaluated before and after the training protocol and after 3 months again, in which kinetic data of the ground reaction force were measured. Results: There were no significant differences in the anterior-posterior and medio-lateral displacement of hemiplegic subjects after the 10 training sessions with the Wii console and these values remained the same after 3 months. Conclusion: The therapy with the Wii console was unable to alter the COP displacement of individuals with hemiplegia.
