Restoration of gait in nonambulatory hemiparetic patients by treadmill training with partial body-weight support.

The effect of a treadmill training with partial body-weight support was investigated in nine nonambulatory hemiparetic patients with a mean poststroke interval of 129 days. They had received regular physiotherapy within a comprehensive stroke rehabilitation program at least 3 weeks before the treadmill training without marked improvement of their gait ability. After 25 additional treadmill training sessions scoring of functional performance and conventional gait analysis showed a definite improvement: gait ability, assessed by the Functional Ambulation Category (0 to 5) improved with a mean of 2.2 points, other motor functions, assessed by the Rivermead Motor Assessment Score with a mean of +3.9 points for gross function (range 0 to 13) and of +3.2 points for leg and trunk section (range 0 to 10)] and gait cycle parameters (p < .01). Muscle tone and strength of the paretic lower limb remained stable. We suggest that treadmill training with partial body-weight support could augment restoration of ambulation and other motor functions in hemiparetic patients by active and repetitive training.
