ObjectiveTo compare virtual reality (VR) combined with functional electrical stimulation (FES) to cyclic FES for improving upper extremity function and health-related quality of life in patients with a chronic stroke.DesignA pilot, randomized, single blinded, controlled trial.SettingStroke rehabilitation inpatient unitParticipantsForty-eight participants with a hemiplegia secondary to a unilateral stroke for >3 months, with a hemiplegic wrist extensor Medical Research Council (MRC) scale score of 1–3.InterventionsFES was applied to the wrist extensors and finger extensors. A virtual-reality(VR) based wearable rehabilitation device was used, combined with FES and virtual activity-based training. The control group received cyclic FES only. Both groups completed 20 sessions, over a 4-week period.Main outcome measuresPrimary outcomes were the change in the Fugl–Meyer Assessment: upper extremity (FMA) and Wolf Motor Function Test (WMFT) scores. Secondary outcomes were the change in the Box and Block test (BB), Jebsen Taylor Hand Function Test (JTT), and Stroke Impact Scale (SIS) scores. Assessments were performed at baseline (T0) and at 2 weeks (T1), 4 weeks (T4), and 8 weeks (T8). Between-group comparisons were evaluated using a repeated measures analysis of variance.ResultsForty-one participants were included in the analysis. Compared to FES alone, VR-FES produced greater increase in FMA–distal score (p=0.011) and marginal improvement in JTT–gross score (p=0.057). VR-FES produced greater, although non-significant, improvements in all other outcome measures, except in the SIS–ADL/IADL score.ConclusionsFES with VR-based rehabilitation may be more effective than cyclic FES to improve distal gross upper extremity function post-stroke.
