Mental Practice Combined with Physical Practice to Enhance Hand Recovery in Stroke Patients

Abstract EN

|Objectives.

To evaluate whether combining mental practice with physical practice training enhances hand function in patients with stroke.

Methods.

10 for treatment and 10 for control were recruited for this pre/posttraining matched case control study.

In the treatment group, subjects underwent combining mental practice with physical practice for four weeks.

In the control group, subjects only participated in physical practice.

Change of hand function and the number of activated voxels of the contralateral somatosensory motor cortex (SMC) acquired by functional magnetic resonance imaging were measured.

Results.

After training, the Action Research Arm Test score increased by 12.65 for treatment and by 5.20 for control.

There was a significant difference in the Action Research Arm Test score between the two groups (P=0.04).

The activated voxels number of the contralateral SMC increased in both groups, but the activated voxels number in the contralateral SMC and the improvement of hand function for treatment were greater than for control.

In the treatment group, the number of activated voxels of the contralateral SMC was positively correlated with better hand function scores.

Conclusions.

Combining mental practice with physical practice may be a more effective treatment strategy than physical training alone for hand recovery in stroke patients.
