[ARTICLE] The variety of methodology in Mirror Therapy practice for improving hand function after stroke. – Full Text PDF
Many studies have shown that a repeated exercises in the mirror visual feedback and motor imagery conditions may help to restore a lasted hand function in stroke patients. The evidence of effectiveness of mirror therapy is promising but the use of this method varies widely within studies. It has been postulated that there is a need to formulate basic rules of mirror therapy application with respect to different stages of stroke or severity of hand paresis. In this article the review of methodological variability of applying mirror therapy to patients after stroke has been presented. The review highlights the benefit effect of mirror therapy on motor recovery and activities of daily living after stroke.
[Abstract] Task-Based Mirror Therapy Augmenting Motor Recovery in Poststroke Hemiparesis: A Randomized Controlled Trial
To establish the effect of the task-based mirror therapy (TBMT) on the upper limb recovery in stroke.
A pilot, randomized, controlled, assessor-blinded trial was conducted in a rehabilitation institute. A convenience sample of 33 poststroke (mean duration, 12.5 months) hemiparetic subjects was randomized into 2 groups (experimental, 17; control, 16). The subjects were allocated to receive either TBMT or standard motor rehabilitation—40 sessions (5/week) for a period of 8 weeks. The TBMT group received movements using various goal-directed tasks and a mirror box. The movements were performed by the less-affected side superimposed on the affected side. The main outcome measures were Brunnstrom recovery stage (BRS) and Fugl-Meyer assessment (FMA)—FMA of upper extremity (FMA-UE), including upper arm (FMA-UA) and wrist–hand (FMA-WH).
The TBMT group exhibited highly significant improvement on mean scores of FMA-WH (P < .001) and FMA-UE (P < .001) at postassessment in comparison to the control group. Furthermore, there was a 12% increase in the number of subjects at BRS stage 5 (out of synergy movement) in the experimental group as compared to a 0% rise at the same stage in the control group.
This pilot trial confirmed the role of TBMT in improving the wrist–hand motor recovery in poststroke hemiparesis. MT using tasks may be used as an adjunct in stroke rehabilitation.
