肌肉疲劳通常引起姿势平衡和肌肉收缩的恶化，例如力量或最大随意收缩（MVC）。本研究旨在探讨经皮电刺激（TENS）对小腿三头肌疲劳后姿势失衡和肌力下降的影响。从2010年3月开始的4个月内，招募了20名没有前庭疾病和视觉障碍的健康受试者，并通过反复随意收缩来诱导肱三头肌的肌肉疲劳。在肌肉疲劳后立即将TENS应用于腓肠肌。姿势摇摆长度，速度和MVC记录在这些条件下：疲劳前，疲劳后，和TENS应用于疲劳肌肉在疲劳后。肌肉疲劳增加姿势不平衡，表现为摇摆长度和速度，减少肌肉收缩（p
Muscle fatigue often induces deterioration of postural balance and muscle contraction, such as strength or maximal voluntary contraction(MVC). This study was to investigate the effects of transcutaneous electrical stimulation(TENS) applied to the fatigued muscles on postural imbalance and decline in muscle strength following fatigue of triceps surae. For the 4 months from March, 2010, twenty healthy subjects without vestibular disease and visual disturbance were recruited and induced muscle fatigue of triceps surea performed by repeated voluntary contraction. TENS was applied to gastocnemius immediately after development of muscle fatigue. Postural sway length, velocity and MVC were recorded under these conditions: pre-fatigue, post-fatigue, and TENS application to fatigued muscle during post-fatigue. Muscle fatigue increased postural imbalance as expressed by sway length and velocity and decreased muscle contraction(p
