Data to produce the results of the publication: “Disentangling acceleration-, velocity- and duration-dependency of the short- and medium-latency stretch reflexes in the ankle plantarflexors”

The work presents the systematic evaluation of the acceleration-, velocity- and duration-dependency of the short- and medium-latency stretch reflexes in the ankle plantarflexors. The stretch rflexes are evaluated using EMG measurements and processing with the systematic evaluation performed through thorough stretch perturbation design.In short, we showed that perturbation acceleration, velocity and duration all shape the M1 and M2 response, often via nonlinear or interacting dependencies. Consequently, systematic execution and reporting of stretch reflex and spasticity studies, avoiding uncontrolled parameter interdependence, is essential for proper understanding of the reflex neurophysiology.

本研究针对踝跖屈肌短时、中潜伏期牵张反射的加速度、速度及时长依赖性开展系统性评估。研究通过精细化牵张扰动设计完成实验流程，并采用肌电图（Electromyography, EMG）测量与信号处理手段对牵张反射进行分析。简言之，本研究证实扰动的加速度、速度及时长均可通过非线性或交互依赖性机制调控M1与M2反射响应。因此，在牵张反射与痉挛研究中，需系统性开展实验并规范报告研究内容，避免参数间存在未受控的相互依赖性，这对正确理解反射神经生理学机制至关重要。
