Introduction: Early Mobilization improves the functional ability and the balance in acute stroke subjects. Supported standing is a common adjunct treatment procedure in early mobilisation of acute stroke individuals who have insufficient lower limb strength, poor trunk to stand actively. Objectives of the Study: To determine the effect of supported standing on functional ability in patients with acute stroke. Study design: Single-blinded Randomized Controlled Trial. Study setting: University teaching hospital in Mangalore. Methodology: Fifty stroke subjects were equally randomized to either the intervention or the conventional group. The Intervention group received the support standing along with the conventional therapy. Supported standing was done with the help of assistive devices like tilt table, standing frame. Thirty minutes of supported standing (based on the tolerance of the patient) with frequent rest periods were given, once in a day for 5 days per week for 2 weeks. Outcome Measures: Functional ability was measured by the River mead Motor Assessment Gross Function Subscale and the Berg Balance Scale. Results: The results of this study showed that the River mead Motor Assessment Gross Function Subscale and the Berg Balance Scale were statistically significant for both within and between group comparison (p__ampersandsignlt;0.05). Conclusions: The present randomized controlled trial study concludes that the supported standing along with the conventional therapy is more effective than the conventional physiotherapy alone in improving functional ability in patients with acute stroke.
