Abstract

The purposes of this study was to determine the effects of limited hyperextension at knee joint using Limited Motion Knee Brace on balance and walking in patients with hemiplegia. The subjects of this study were 20 post-stroke hemiplegic patients admitted. Subjects were randomly assigned to either experimental group (Limited Motion Knee Brace group) or control group (manual restriction group). Both groups received traditional physical therapy intervention. The effects of each therapeutic method were evaluated by measurements of gait ability assesment, Berg balance scale (BBS), 10-meter walk speed (10MWS), Timed Up & Go (TUG) Test. The results of this research were as followings: (1) After treatment, there were significant BBS scores differences in both experimental and control group compared with pre-treatment(p<0.05). (2) After treatment, there were significant TUG test scores differences in both experimental and control group compared with pre-treatment (p<0.05). (3) After treatment, there were significant 10MWS differences in both experimental and control group compared with pre-treatment (p<0.05). (4) There were significant BBS scores differences in third and fourth week between experimental and control group (p<0.05). It was concluded that Limited Motion Knee Brace was effective for improving balance and for reducing fatigue for experimental group. Therefore, further studies are required to investigate the effect of knee orthosis for improving balance and walking in patients with hemiplegia.
