Comparative Effect of Vision Deprived Balance Training over Free Vision Balance Training Among Stroke Subjects

Background: The dramatic increase in the incidence and prevalence of neurological disorder like stroke has always demanded the need of new interventions in limiting the disability outcome. Disturbed balance is one of the common difficulties in stroke subjects. Several researches have conducted with the process of limiting the disability but still not controlled fully. The objective of the study is to find out the effect of balance exercise with deprivation of visual feedback in stroke subjects. Method: Total number of thirty subjects participated in the study. The duration of study was four weeks with five sittings in a week and with duration of sixty minutes in each training session. Data was collected using Berg balance scale and the get up and go test, statistical analysis using the Wilcoxon’s signed rank test and paired T-test. Result: The mean value of timed get up and go test in group A was 16.93 with a standard deviation of ±3.86. The t-value of the study was 2.63 with P-value of 0.007.The study found significant difference in effect as the calculated P < 0.05. The results showed that the conventional therapy along with masked vision could bring about significant changes in balance, mobility and function of patients suffering from balance impairment among post stroke. The data analysis found the significant difference between the visions deprived balance training to that of free vision balance training. Conclusion: Subjects with masked vision showed better outcomes on balance and get up and go test. Balance performance and movement was found better in subjects with deprived vision than those with free vision.
