Abstract
BACKGROUND: The improvement of the upper limb disability, which is mainly caused by stroke, is still one of the rehabilitation treatment challenges. However, the effectiveness of task-based mirror therapy (TBMT) on subacute stroke with moderate and severe upper limb impairment has not been deeply explored. AIM: The purpose of this study was to investigate the effects of TBMT, in comparison to occupational therapy, in moderate and severe upper limb impairment by analyzing the motor function and activities of daily living in subacute stroke patients. DESIGN: A randomized controlled trial. SETTING: Rehabilitative inpatient unit. POPULATION: Thirty patients with moderate and severe-subacute stroke recruited from the Second Affiliated Hospital of Chongqing Medical University have been randomly divided into two groups; the task-based mirror therapy group (N.=15) and the control group (N.=15). METHODS: The first group received TBMT while the control group only underwent only occupational therapy without a mirror utilization. Taking into consideration that both groups received conventional therapy. The intervention time was equal for both groups consisting of 25 minutes per day for 25 days. Fugl-Meyer Assessment (FMA), Brunnstrom Assessment (BRS), Modified Barthel Index (MBI), and Modified Ashworth Scale (MAS) were used to assess the outcomes for this study. RESULTS: After 25 sessions of treatment, the patients in both groups have shown-improvement in the activates of daily living, motor recovery, and motor function. No significant differences between the two groups were observed on BRS and MBI. However, interestingly, the results of the TBMT group were significantly better than the control group in FMA (P<0.05) and certain aspects of MAS (elbow flexion, wrist flexion, wrist extension, and fingers extension with P<0.05). CONCLUSIONS: This study shows that the combination of conventional rehabilitation treatment and TBMT is an effective way to improve the functional recovery in the upper limb stroke patients. CLINICAL REHABILITATION IMPACT: TBMT is a therapeutic technique that can be used in subacute stroke patients with moderate and severe upper limb impairment.
