The effects of electromyography-triggered neuromuscular electrical stimulation plus tilt sensor functional electrical stimulation training on gait performance in patients with subacute stroke: a randomized controlled pilot trial.

The effects of electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation on ankle dorsiflexion during walking are unclear. This study investigated whether combined electrical stimulation training affects gait performance in patients with stroke. Thirty-six patients were randomly assigned to a control (n = 13), electromyography-triggered neuromuscular electrical stimulation training (single electrical stimulation group, n = 12), or a combined electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training (combined electrical stimulation group, n = 11) group. Both experimental groups undertook 60-minute interventions for two weeks. All patients' gait performances were evaluated according to walking speed and trunk acceleration during 10-meter walking tests undertaken pre-intervention and at two weeks post-intervention. A wireless triaxial accelerometer measured trunk acceleration, and the root mean square values of the vertical, mediolateral, and anterioposterior planes were calculated from randomly selected 10-step sequences. Compared with baseline, the 10-meter walking tests improved significantly after two weeks in the single and combined electrical stimulation groups. In the combined electrical stimulation group, the 10-meter walking tests scores and root mean square of the mediolateral plane improved significantly compared with those in the control group. Electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training may improve body perturbation stability and walking quality.
