Abstract


Stroke is an acute onset of neurological dysfunction due to an abnormality in cerebral circulation with resultant signs and symptoms that corresponds to involvements of the focal areas of brain. Stroke results into decreased proprioceptive sense and muscle strength which leads to impaired balance. Hence in this study, two visual biofeedback exercises were selected to find out the effect on balance in stroke patients. 26 subjects fulfilling the inclusion criteria were selected and divided into control (n=13) and experimental (n=13) groups. Pre intervention step test was measured. The exercise regime protocol was same for both the groups except the control group underwent visual biofeedback exercises in parallel bars in front of the mirror and the Experimental group underwent computerised targeted visual biofeedback exercises for 5 sessions/week for 4 weeks. Step test was reassessed at the end of 4th week. Data analysis was done by using paired and unpaired t-test where p value was <0.005. The results of the present study showed that there was no significant difference in the post step test values of experimental group when compared to the control group. Both the groups showed improvement in the post intervention step test scores. So, it can be concluded that both the visual biofeedback exercises were equally effective to improve the balance in stroke patients.
