The Effectiveness of Functional Electrical Stimulation Based on a Normal Gait Pattern on Subjects with Early Stroke : A Randomized Controlled Trial

Abstract EN

Objective.

To investigate the effectiveness of four-channel FES based on a normal gait pattern on improving functional ability in subjects early after ischemic stroke.

Methods.

Forty-five subjects were randomly assigned into a four-channel FES group (n=16), a placebo group (n=15), or a dual-channel group (n=14).

Stimulation lasted for 30 min in each session with 1 session/day, 5 days a week for 3 weeks.

All subjects were assessed at baseline, at 3 weeks of treatment, and at 3 months after the treatment had finished.

The assessments included Fugl-Meyer Assessment (FMA), the Postural Assessment Scale for Stroke Patients (PASS), Berg Balance Scale (BBS), Functional Ambulation Category (FAC), and the Modified Barthel Index (MBI).

Results.

All 3 groups demonstrated significant improvements in all outcome measurements from pre- to posttreatment and further gains at followup.

The score of FMA and MBI improved significantly in the four-channel group at the end of the 3 weeks of training.

And the scores of PASS, BBS, MBI, and FAC in the four-channel group were significantly higher than those of the placebo group.

Conclusions.

This study indicated that four-channel FES can improve motor function, balance, walking ability, and performance of activities of daily living in subjects with early ischemic stroke.
