Compare the Effectiveness of Physio Ball and Physio Bed Trunk Exercices for Improving Trunk Control and Balance among Hemiplegic Stroke Patients: A Randomized Clinical Trial.

Abstract

Background. Stroke causes impairment of trunk musculature in with in addition to limb muscles. After stroke, hemiplegia causes motor paralysis of the limb muscles affects one side of the body but contrary to the trunk muscles which are also impaired on both ipsilateral and contralateral side of body to that of lesion. Objective. The aim of this study this study is to compare the effectiveness of physio ball trunk rehabilitation exercise with physio bed trunk rehabilitation exercise program for improving trunk control and balance among hemiplegic stroke patients. Methods. Design of this study was single blind Randomized Clinical Trial. The study was conducted in the CRP (Savar Centre). 34 patients with stroke who met the inclusion criteria were randomly allocated to the control and experimental group (1:1 ratio). Each group got 16 treatment sessions (30min/d for 4 days in 4 constructive weeks). Data was collected by Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS). Analysis of data: SPSS version 23 was used for data analysis. Inferential statistics- nonparametric statistics such as Mann-Whitney U test, Wilcoxon test were used for data was analysis. Besides, effect size index (d) was calculated for each of the outcome measures. Result. After treatment, both the groups showed significant improvement (p<.05) but the physio ball exercise group improved more significantly (p<.05) than the physio bed exercise group in terms of trunk control and functional balance (sit to stand and transfer). Conclusion. 30 min Physio ball exercise program was proven to be more effective than physio bed exercise in trunk control and functional balance (sit to stand and transfer) of patients with stroke.
