为了增加活动范围，理疗师经常使用被动拉伸作为一种增加关节周围运动的方法。除了临床研究显示有效性，从而支持循证实践外，基础科学还可以解释一种技术在已知有效的情况下可能如何工作。本文的目的是回顾当肌肉纤维被动拉伸时可能发生的潜在细胞事件。一个应用于脚踝的被动拉伸的生物力学例子被用来提供一种在细胞和分子水平上讨论被动拉伸的方法。从组织生物力学的角度讨论了被动拉伸对肌肉纤维和相关结缔组织的影响。重点放在潜在参与牵张感觉和信号转导的结构上，并探索可能导致肌原纤维形成的机制。
To increase range of motion, physical therapists frequently use passive stretch as a means of gaining increased excursion around a joint. In addition to clinical studies showing effectiveness, thereby supporting evidence-based practice, the basic sciences can explain how a technique might work once it is known to be effective. The goal of this article is to review the potential cellular events that may occur when muscle fibers are stretched passively. A biomechanical example of passive stretch applied to the ankle is used to provide a means to discuss passive stretch at the cellular and molecular levels. The implications of passive stretch on muscle fibers and the related connective tissue are discussed with respect to tissue biomechanics. Emphasis is placed on structures that are potentially involved in the sensing and signal transduction of stretch, and the mechanisms that may result in myofibrillogenesis are explored.
