Background
To establish the effect of the task-based mirror therapy (TBMT) on the upper limb recovery in stroke.
Methods
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).
Results
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.
Conclusions
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.
