To discuss the role of proprioception in motor control and in activation of the dynamic restraints for functional joint stability.
Information was drawn from an extensive MEDLINE search of the scientific literature conducted in the areas of proprioception, motor control, neuromuscular control, and mechanisms of functional joint stability for the years 1970-1999.
Proprioception is conveyed to all levels of the central nervous system. It serves fundamental roles for optimal motor control and sensorimotor control over the dynamic restraints.
CONCLUSIONS/APPLICATIONS: Although controversy remains over the precise contributions of specific mechanoreceptors, proprioception as a whole is an essential component to controlling activation of the dynamic restraints and motor control. Enhanced muscle stiffness, of which muscle spindles are a crucial element, is argued to be an important characteristic for dynamic joint stability. Articular mechanoreceptors are attributed instrumental influence over gamma motor neuron activation, and therefore, serve to indirectly influence muscle stiffness. In addition, articular mechanoreceptors appear to influence higher motor center control over the dynamic restraints. Further research conducted in these areas will continue to assist in providing a scientific basis to the selection and development of clinical procedures.
探讨本体感觉在运动控制和功能关节稳定性的动力约束激活中的作用。
从本体感觉、运动控制、神经肌肉控制以及功能关节稳定性机制等领域的科学文献中进行了广泛的 MEDLINE 搜索，以获取信息，时间跨度为 1970 年至 1999 年。
本体感觉传递到中枢神经系统的所有水平。它对最佳运动控制和动力约束的感觉运动控制起着基本作用。
结论/应用：尽管对于特定机械感受器的确切贡献仍存在争议，但作为一个整体，本体感觉是控制动力约束和运动控制激活的重要组成部分。肌肉梭是增强肌肉硬度的关键因素，被认为是动态关节稳定性的重要特征。关节机械感受器被认为对γ运动神经元的激活具有重要影响，因此可以间接影响肌肉硬度。此外，关节机械感受器似乎还影响着高级运动中枢对动力约束的控制。在这些领域进行的进一步研究将继续为临床程序的选择和发展提供科学依据。
