目前，物理治疗被认为是一种有效的、可逆的、保守的治疗颞下颌疾病（TMD）的方法。本研究的目的是探讨在物理治疗过程中，在头颈部以外的远端部位使用对抗刺激缺血性疼痛作为恢复肌肉力量的方法的可行性。本研究招募20名健康无症状女性受试者。实验进行了两天，这两天的实验随机分配到有或没有反刺激的实验中。反刺激应用于受试者的左手使用次最大努力止血带程序。在右侧测量最大咬合力、手指捏合力和手握力，并比较有反刺激和没有反刺激的结果。结果表明，刺激组的平均最大咬合力显著高于未刺激组，且手指按压力有增大的趋势，而握力则无显著差异。结果表明，头颈部外的反刺激可能有助于增加咬合力，并可能适用于TMD的治疗，以恢复咀嚼肌的力量。
Abstract Today, physical therapy is recognized as an effective, reversible, and conservative treatment for temporomandibular disorders (TMD). The purpose of this investigation is to explore the feasibility of utilizing counter irritation with ischemic pain at a remote site outside of the head and neck region as a method for restoring muscle force in a course of physical therapy. Twenty healthy asymptomatic female subjects were recruited for this study. The experiments were performed over two days, with the two experimental days randomly assigned to the experiment performed with or without counter irritation. The counter irritation was applied to the subject’s left hand using a submaximal effort tourniquet procedure. The maximal bite, finger-pinch, and handgrip forces were measured on the right side, and the results from the days with and without the counter irritation were compared. As a result, a significantly higher mean maximal bite force and a trend toward higher finger-pinch force were observed with the irritation than without the irritation, while there was no significant difference in the handgrip force. These findings indicate that counter irritation outside of the head and neck may be useful for increasing bite force, and may be applicable in the treatment of TMD for the restoration of masticatory muscle force.
