Abstract

OBJECTIVE:

To demonstrate the effect of rhythmical auditory stimulation in a musical context for gait therapy in hemiparetic stroke patients, when the stimulation is played back measure by measure initiated by the patient's heel-strikes (musical motor feedback). Does this type of musical feedback improve walking more than a less specific gait therapy?

DESIGN:

The randomized controlled trial considered 23 registered stroke patients. Two groups were created by randomization: the control group received 15 sessions of conventional gait therapy and the test group received 15 therapy sessions with musical motor feedback.

SETTING:

Inpatient rehabilitation hospital.

SUBJECTS:

Median post-stroke interval was 44 days and the patients were able to walk without technical aids with a speed of approximately 0.71 m/s.

MAIN OUTCOME MEASURES:

Gait velocity, step duration, gait symmetry, stride length and foot rollover path length (heel-on-toe-off distance).

RESULT:

The test group showed more mean improvement than the control group: stride length increased by 18% versus 0%, symmetry deviation decreased by 58% versus 20%, walking speed increased by 27% versus 4% and rollover path length increased by 28% versus 11%.

CONCLUSION:

Musical motor feedback improves the stroke patient's walk in selected parameters more than conventional gait therapy. A fixed memory in the patient's mind about the song and its timing may stimulate the improvement of gait even without the presence of an external pacemaker.
