[[alternative]]Effect of Mirror Therapy on Motor Function of Upper Extremity in Chronic Stroke Patients

[[abstract]]慢性中風患者常伴隨有上肢動作功能缺損，並使患者減少使用患側上肢。近來研究發現鏡像治療一般認為對中風後上肢動作功能復健可能有幫助。本研究旨在探討鏡像治療介入對慢性中風患者在上肢動作功能的療效。共有 16 名發病時間大於 6 個月的中風患者，隨機分為鏡像治療組(8 名)及控制組(8 名)Ƕ鏡像治療組接受每天一小時的鏡像治療及半小時的傳統治療，每週五天持續四週；控制組則接受相同治療量的傳統治療介入Ƕ研究使用傅格梅爾動作評量表(Fugl-Meyer motor assessment, FMA)的上肢動作部份來評估受試者上肢動作功能的改變，同時利用腕動計來評量受試者在日常生活中上肢的使用情形，再加上視覺化之疼痛及疲憊程度自我評量表來評量受試者疼痛及疲勞的程度Ƕ在四週的介入後，鏡像治療組在 FMA 的分數進步程度明顯高於控制組(鏡像組:6.5 分±4.3 分；控制組 3.12分±2.03 分，p6 months) patient were included in this study and randomly assigned to the mirror therapy(MT) group (n=8) and the control (RC) group (n=8). The mirror therapy group received mirror therapy program for 1 hour and conventional therapy for 0.5 hour per day, 5 days a week, in 4 weeks. The control group received the does-matched conventional therapy. The Fugl-Meyer Assessment (FMA) and Micro-mini Motion-logger, were used to assess the changes in upper extremity motor function and the ratio of affected arm use to non-affected arm use after intervention. The visual analog scales were also applied for assessing the level of pain and fatigue that may be induced by intervention. In the upper extremity function, the scores of FMA increased more in MT group (6.5±4.3, Mean ± SD) than in RC (3.12±2.03) group (p<.05). The ratio of affected arm use to non-affected arm use reduced more in MT( -0.24±0.16) group than in RC(0.06±0.16) group significantly (p<.05). No significant difference were found in pain and fatigue level between two groups. This study supports that both therapy are effective for upper extremity motor function rehabilitation in chronic stroke patients, Therefore, chronic stroke patients made more improvement in upper motor functions with combined mirror therapy with conventional therapy. However, it would be noticed that the ratio of affected arm use to non-affected arm use may be reduced after mirror therapy intervention
