Motor imagery for gait rehabilitation in post-stroke hemiparesis.
OBJECTIVE
Reports have described the contribution of motor imagery (MI) practice for improving upper-extremity functions in patients with hemiparesis following stroke. The purpose of this case report is to describe the use of MI practice to attempt to improve walking in an individual with hemiparesis.


METHODS
A 69-year-old man with left hemiparesis received MI gait practice for 6 weeks. Intervention focused on task-oriented gait and on impairments of the affected lower limb. Preintervention, midterm, postintervention, and follow-up measurements of temporal-distance stride parameters and sagittal kinematics of the knee joint were taken.


RESULTS
At 6 weeks postintervention, the patient had a 23% increase in gait speed and a 13% reduction in double-support time. An increase in range of motion of the knees also was observed. No changes in gait symmetry were noted.


CONCLUSIONS
The outcomes suggest that MI may be useful for the enhancement of walking ability in patients following stroke. Because improvement was mainly in temporal-distance gait variables and knee movement, imagery practice probably should focus on its specific impairments during gait in order to affect the performance of the paretic lower extremity.
