Gait Training For Acute Stroke: Functional Neuromuscular Stimulation (FNS) and Weight Supported Treadmill Training

Completed · Phase 4

Conditions studied: Stroke

In brief

Conventional rehabilitation does not restore normal, safe gait to many stroke survivors. Functional neuromuscular stimulation (FNS) using intramuscular (IM) electrodes (FNS-IM) improved persistent gait deficits for patients with chronic stroke (1-7 years post stroke), but required a long protocol of 6-18 months. For chronic deficits, a shortened response to treatment (3 months) was obtained by combining FNS-IM with body weight-supported treadmill training (BWSTT). Gains included strength, coordination, gait kinematics, walking endurance, and quality of life. Gait deficits treated in the chronic phase are more resistant to treatment than in the early recovery phase, because chronic, abnormal movement patterns are more ingrained. Therefore, during the early recovery phase, it is likely that a relatively greater treatment response will be obtained. The purpose of the proposed work is to test the combination FNS-IM + BWSTT during the early recovery phase following stroke. Hypothesis I is: FNS-IM + BWSTT will restore volitional gait more completely for subjects during the early recovery phase following stroke, compared to BWSTT alone. Subjects will be admitted at 1-11 months after stroke. Thirty five subjects will be randomized to one of the two treatment groups. They will be treated for 48 sessions, four sessions/week. Primary outcome measures will be: kinematic swing phase gait components, energy cost of gait, and an index of walking endurance. Secondary outcome measures will be kinematic stance phase gait components and gait speed. The second set of hypotheses will test the relationship between restoration of mobility and measurements of impairment, function and quality of life.
