Background
Asymmetric movements with both hands contributed to the improvement of spatially coupled
motion. Thus, the aim of this study was to investigate the effects of an asymmetric
training program using virtual reality reflection equipment on upper limb function
in stroke patients.
Methods
Twenty-four stroke patients were randomly allocated to an experimental group (n = 12)
or a control group (n = 12). Both groups participated in conventional physical therapy
for 2×30 min/d, 5 d/wk, for 4 weeks. The experimental group also participated in an
asymmetric training program using virtual reality reflection equipment, and the control
group participated in a symmetric training program. Both asymmetric and symmetric
programs were conducted for 30 min/d, 5 d/wk, for 4 weeks. To compare upper limb function
before and after intervention, the Fugl–Meyer Assessment (FMA), the Box and Block
Test (BBT), grip strength, range of motion (ROM), and spasticity were assessed.
Results
Both groups showed significant increases in upper limb function, excepting spasticity,
after intervention (P < .05, 1-way repeated-measures analysis of variance [ANOVA]). A significant group–time
interaction was demonstrated only for shoulder/elbow/wrist items of FMA, BBT, grip
strength, and ROM of wrist flexion, extension, and ulnar deviation (P < .05, 2-way repeated-measures ANOVA).
Conclusions
This study confirms that the asymmetric training program using virtual reality reflection
equipment is an effective intervention method for improving upper limb function in
stroke patients. We consider that an additional study based on a program using virtual
reflection, which is more functional than performing simple tasks, and consisting
of tasks relevant to the activities of daily living be conducted.
