OBJECTIVE: To evaluate the effect of mental practice on motor imagery ability and
assess the influence of motor imagery on gait rehabilitation in sub-acute stroke.
DESIGN: Randomized controlled trial. SUBJECTS: A total of 44 patients with gait
dysfunction after first-ever stroke were randomly allocated to a motor imagery
training group and a muscle relaxation group. METHODS: The motor imagery group
received 6 weeks of daily mental practice. The relaxation group received a muscle
relaxation programme of equal duration. Motor imagery ability and lower limb
function were assessed at baseline and after 6 weeks of treatment. Motor imagery
ability was tested using a questionnaire and mental chronometry test. Gait
outcome was evaluated using a 10-m walk test (near transfer) and the Fugl-Meyer
assessment (far transfer). RESULTS: Significant between-group differences were
found, with the vividness of kinesthetic imagery and the walking test results
improving more in the motor imagery group than in the muscle relaxation group.
There was no group interaction effect for the far transfer outcome score.
CONCLUSION: Motor imagery training may have a beneficial task-specific effect on
gait function in sub-acute stroke; however, longer term confirmation is required.
