The aim of research: To assess the effectiveness of virtual reality based exercises for regaining motor functions, balance and quality of life in stroke survivors. Research goals: 1. To evaluate the movement amplitude and muscle strength of an affected arm of patients belonging to the treatment and the control groups before and after physiotherapy. 2. To evaluate the arm motor activity of patients belonging to the treatment and the control groups. 3. To evaluate the ability to keep balance of patients belonging to the treatment and the control groups before and after physiotherapy. 4. To analyse the quality of life of patients belonging to the treatment and the control groups before and after physiotherapy. The contingent, organisation and methodology of the research: The study included 20 individuals (11 men and 9 women) who had suffered a stroke previously. Subjects were divided into two groups: the first group (VR, n = 10) was treated using a combination of a usual physiotherapy and virtual reality games as additional treatment, while the second group (KIN, n = 10) was treated using only a usual physiotherapy. Before and after the study the muscle strength of the respondents was rated according to the Lovett scale, the balance was rated using Berg scale affected, and arm motor activity assessed with the help of Wolf motor activity scale. Range of motion was measured with a goniometer, and the quality of life was assessed using a questionnaire SF - 36. Conclusions: 1. When combined with virtual reality games, physiotherapy has the same positive impact on the range of motion and the muscle strength of an affected arm’s upper arm, forearm and wrist as the usual physiotherapy. 2. Introduction of virtual reality games shows an increased effect on affected arm’s motor activity when compared to the usual physiotherapy. 3. When combined with virtual reality games, physiotherapy has the same positive impact on the balance as the usual physiotherapy. 4. Introduction of virtual reality games proves to have greater ...
