Abstract
Objective: To compare the effects of mirror therapy combined with mesh-glove stimulation (MGS), mirror therapy with placebo stimulation (MTP), and conventional upper-limb rehabilitation (CR) on sensorimotor functions and daily functions for patients with chronic stoke.
Design: A randomized, pretest-posttest, placebo-controlled design was used.
Settings: Outpatient rehabilitation clinics
Subjects: Twenty-three patients (mean age = 50.84 year; mean time after stroke = 27 month) were randomized to MGS, MTP, or CR groups. Each group received treatment for 90 minutes/day and 5 days/week over 4 consecutive weeks.
Main measures: Primary outcomes were Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test. Secondary outcomes were Modified Ashworth Scale (MAS), motor items of Functional Independence Measure (FIM), Motor Activity Log (MAL), 10-Meter Walking Test, sensory section of the Fugl-Meyer Assessment, Revised Nottingham Sensory Assessment, and kinematic analysis.
Results: After four week treatment, all participants had better motor recovery. Compared with CR group, patients received MGS or MTP significantly reduced motor impairment in distal part of FMA, decreased muscle tone in distal part of MAS and less shoulder abduction in reaching movement. Enhanced functional performance was found for MGS group in the MAL and locomotion subcomponent of the FIM. No significant difference but a positive trend for MGS was showed in sensory outcomes.
Conclusions: Compared with CR group, MGS and MTP may improve motor impairment of the distal upper extremity and prevent compensatory pattern at shoulder joint. MGS group may enhance the effect of activity level on functional arm-use and locomotion than other groups. These positive results on sensorimotor functions and daily functions encourage enrolling larger sample size to confirm the findings for similar participants.
