Abstract
Introduction: The aim of the present study was to evaluate the effect of mirror therapy on balance ability of stroke patients in two subacute and chronic stages.
Methodology: Patients referring to the Tabasom Rehabilitation Center (n=150) with stroke in two subacute and chronic stages were screened for this study. Among these patients, 30 patients in the subacute phase and 30 in the chronic phase participated in the study voluntarily by giving informed consent. Sixty patients with poststroke hemiparesis randomly assigned to four equal groups with 15 subjects including mirror therapy subacute, mirror therapy chronic, sham therapy subacute, and sham therapy chronic group. The experimental groups received 30 minutes mirror therapy and 30 minutes conventional rehabilitation therapy for 60 minutes per day, with a 10 minute rest period halfway through the session. Participants received training 2 days/week for 8 weeks. The participants in the control group received 30 minutes sham therapy and 30 minutes conventional rehabilitation therapy for total of 60 minutes per day on the same day. Practice with mirror include two parts, the balance training in front of a mirror in such a way that the mirror is in front of the person with visual feedback to correct his position during the movements and the mirror therapy, the patients performed a range of motion of lower extremities of less-affected side in front of the mirror and observed only the mirror image. The data was gathered by the Berg balance scale (BBS) test and were analyzed by descriptive statistics, independent t-test with SPSS software. The statistical significance level was set at α=0.05.
Results: The results showed a significant difference in BBS scores of the subacute experimental group in comparison to the control group(P<0.05). but in chronic experimental and control groups was no significant difference between BBS scores (P>0.05).
Discussion: Various studies have been done over years to test the efficacy of mirror therapy in rehabilitation of stroke in all the two stages but no conclusive idea about which stage subacute or chronic is benefited the most. Many researches showed that it may be dependent on part of the exact location of the lesion and duration of paralysis following the stroke. It is concluded that mirror therapy is more beneficial in improving balance ability in subacute stage than chronic stage in patients with poststroke hemiparesis.
