ABSTRACT
Introduction: In stroke balance impairment in sitting which is important early predictor of motor and functional outcome. Visual feedback training (VFT) has largely been used as a rehabilitation method and proven an effective therapy in enhancing balance control in patients with stroke. Very few literatures available on dynamic sitting balance with VFT and upper limb reaching activity.
Material and Methods: Experimental study (RCT) was conducted on 40 participants with stroke of age 25-65 years were included and equally distributed in both the experimental and control group (20 in each group). The demographic variables and stroke related parameters (mFRT and TIS Score) in both groups were comparable. The experimental group received conventional therapy (CT) plus VFT and control group received conventional therapy alone (CT) for 4 weeks (5 days/week).
Data analysis and Results: Statistical software, STATA, version 10.1 2011wasused. Anthropometric parameters, Mean centre of foot pressure (COFP), mFRT and TIS Score were compared between Experimental and Control group by performing independent t-test (paired t-test). Mean COFP, mFRT and TIS Score were compared between pre and post test by performing paired t-test. Changes (effects) in COFP, mFRT and TIS score after post test intervention between experimental and control group were compared by performing independent t-test. Chi-square test was used to compare categorical variables. P<0.05 was considered as statistical significance.
Conclusion: The VFT is an effective tool for improving dynamic sitting balance, weight loading response on paretic side as well as improves the trunk control in 4 weeks of intervention in patients.
