The cerebellum and initiation of movement: the stretch reflex.
Studies of the stretch reflex in decerebrate cats indicate a phase advance of peak sinusoidal tension in steady-state cycles between 0.1 and 10 Hz. This phase advance is reduced in acute and chronic cerebellectomy, as shown in previous investigations. Also, the augmentation of muscle peak tension in initial sinusoidal stretch cycles at 0.5-5 Hz has been found to be reduced during the time of re...
متن کاملPassive and Active Glenohumeral Joint Stiffness
1. Introduction It is not clear how different portions of the capsuloligaments and muscles contribute to GH stability. Since GH instabilities occur frequently in various shoulder injuries, it is important to understand the restraining forces provided by various structures in the GH-joint. A better understanding of the GH stiffness will also help improve existing shoulder models by including GH ...
متن کاملEstimation of Time-Varying, Intrinsic and Reflex Dynamic Joint Stiffness during Movement. Application to the Ankle Joint
Dynamic joint stiffness determines the relation between joint position and torque, and plays a vital role in the control of posture and movement. Dynamic joint stiffness can be quantified during quasi-stationary conditions using disturbance experiments, where small position perturbations are applied to the joint and the torque response is recorded. Dynamic joint stiffness is composed of intrins...

متن کاملMuscle stiffness and spinal stretch reflex sensitivity in the triceps surae.
CONTEXT Greater musculotendinous stiffness may enhance spinal stretch reflex sensitivity by improving mechanical coupling of the muscle spindle and the stretch stimulus. This heightened sensitivity would correspond with a shorter latency and higher-amplitude reflex response, potentially enhancing joint stability. OBJECTIVE To compare spinal stretch reflex latency and amplitude across groups t...
