The effects of physical therapy on exaggerated muscle tonicity, balance and quality of life on hemiparetic patients due to stroke.

OBJECTIVE To determine the effects of physical therapy on balance, exaggerated muscle tonicity and quality of life on patients with hemiparesis. METHODS This quasi-experimental study was conducted in 2011 among male hemiparetic patients secondary to stroke, at a physiotherapy centre in Neyshabur, Iran. Twenty-four patients were randomly assigned to two equal groups representing the cases and the controls.The cases were assigned to do the practical protocol for 4 weeks.To collect the data, Berg Balance Scaling, Modified Ashworth Scale, Barthel Activities of Daily Living Index and demographic questionnaires were used. Paired and un-paired t-tests were used to analyse data. All analyses were done on SPSS 16. RESULTS The two groups were similar before intervention. Post-test analysis showed that the average balance and quality of life significantly improved (p<0.001) among the cases, and the quadriceps muscle tonicity decreased (p<0.001). Among the controls, there was no significant change between pre-test and post-test readings. CONCLUSIONS Physical therapy can enhance balance and quality of life of hemiparetic patients and reduces their exaggerated muscle tonicity.
