CONTEXT/OBJECTIVE: Functional electrical stimulation (FES) is commonly used in rehabilitation to generate electrically-induced muscle contractions. FES has been shown to assist in the recovery of voluntary motor functions after stroke or spinal cord injury. However, discomfort associated with FES can motivate patients to withdraw their participation from FES therapy despite its benefits. To address this issue, a functional electrical stimulator, called MyndMove™ (MyndTec Inc., Canada), has been developed to generate more comfortable contractions than conventional stimulators.
Cross-sectional, interventional, with two treatment arms.
A laboratory within a rehabilitation center.
Twelve able-bodied participants.
FES delivered with two different stimulators, MyndMove™ and Compex Motion (Compex, Switzerland), during muscle contractions of high, moderate and low stimulation intensity.
Comfort-related preference to a given stimulator and the discomfort score rated through a Numeric Rating Scale (NRS-101) for both stimulators.
Participants perceived a reduction in discomfort during high-intensity stimulation generated using MyndMove™. In addition, MyndMove™ stimulations were preferred in 60% of all contractions. The reduction in discomfort associated with MyndMove™ might be due the fact that MyndMove™ delivers less charge to generate contractions of equivalent intensity, compared to Compex Motion.
Reducing discomfort during FES may help in generating stronger and more clinically useful contractions, increasing accessibility of FES therapy to include individuals with low tolerance to FES.
背景/目的：功能性电刺激（FES）常用于康复治疗中，以产生电诱导的肌肉收缩。FES 已被证明有助于中风或脊髓损伤后恢复自主运动功能。然而，与 FES 相关的不适会促使患者尽管了解 FES 的益处但仍退出 FES 治疗。为了解决这个问题，一种名为 MyndMove™（MyndTec Inc.，加拿大）的功能性电刺激器被开发出来，它可以产生比传统刺激器更舒适的收缩。
横断面、干预性，有两个治疗臂。
康复中心内的一个实验室。
12 名健康参与者。
使用两种不同的刺激器，MyndMove™和 Compex Motion（Compex，瑞士），在高、中、低刺激强度下进行肌肉收缩时施加 FES。
对给定刺激器的舒适度相关偏好以及通过 Numeric Rating Scale（NRS-101）对两种刺激器的不适感评分。
参与者在使用 MyndMove™产生的高强度刺激下感觉不适减轻。此外，MyndMove™ 在 60%的收缩中更受青睐。与 MyndMove™ 相关的不适感降低可能是因为与 Compex Motion 相比，MyndMove™ 输送的电荷量较少，从而产生等效强度的收缩。
减少 FES 过程中的不适感可能有助于产生更强、更具临床实用价值的收缩，从而增加对低耐受 FES 的个体的 FES 治疗的可及性。
