Using an isokinetic exercise machine to improve the gait pattern in a hemiplegic patient. A case report.

This paper presents the case report of a hemiplegic patient who was treated in a therapeutic exercise program using a Kinetron* bilateral lower extremity isokinetic exercise machine. The therapist wanted to identify the benefits this machine might have in improving the gait pattern of a hemiplegic patient. Specifically, he wanted to determine if the machine could inhibit a strong extensor synergy pattern in the involved lower extremity of a hemiplegic patient by first increasing the ability of the patient to initiate active and controlled hip flexion in the same extremity. The authors expected that if the extensor thrust was reduced, then sufficient, voluntary hip flexion would be possible, which would, in turn, promote a more normal gait pattern for ambulation.
