The effect of functional stretching exercises on functional outcomes in spastic stroke patients: A randomized controlled clinical trial

Background: Stroke is the biggest cause of disability in adults. Spasticity is a primary impairment of stroke with a highly variable prevalence. In the present research, we aimed to determine the impact of functional stretching exercises on functional outcomes in stroke patients. Methods: Thirty stroke patients were randomized into two groups-Experimental group and control group for the purposes of the study. The subjects in the experimental group participated in a functional stretching training program at the rehabilitation center thrice a week for four weeks. The subjects in both groups were evaluated in 3 intervals, once at baseline, once at the end of the program, and once at 2 months following the program. Clinical assessments, such as measuring spasticity, were conducted using the Modified Modified Ashworth Scale (MMAS). Functional outcomes were also evaluated, using the Timed Up and Go (TUG) test, as well as the Timed 10-Meter Walk Test (WTT). Friedman test in SPSS version 22.0 was used to analysis the response variables with respect to each stage of evaluation. Spearman rank correlation was also used to measure correlation among clinical assessments and functional outcomes. Results: The comparison between two groups showed significant differences only in the Modified Modified Ashworth Scale and Visual Analogue Scale (VAS) post treatment. The experimental group showed significant differences in the MMAS (p = 0.002), WTT (p < 0.001), and TUG (p < 0.001) scores. Nevertheless, the scores of the control group were not significantly different in different stages of evaluation. Conclusion: The findings of the study suggest that using functional stretching exercises can improve functional outcomes in chronic spastic stroke patients. (C) 2017 Elsevier Ltd. All rights reserved.
