Jaw stretch reflexes in children
Experimental Brain Research, 2005The substantial morphological transformations that occur during human development present the nervous system with a considerable challenge in terms of motor control. Variability of skilled motor performance is a hallmark of a developing system. In adults, the jaw stretch reflex contributes to the functional stability of the jaw.

Eyelid Reflex Response to Stretch
Nature, 1962AMONG the evidence of consciousness in the human subject, the position of the upper eyelid fulfils a significant role, and varies with the degree of attention1. It is of interest, therefore, to understand the mechanisms causing eyelid movement and particularly the relationship of local automatic reflexes to-this function.

Functional Stretch Reflex (FSR) — a Cortical Reflex?
1976Publisher Summary This chapter presents an experimental study to discuss the role of reflexes during functional activity. The time from initiation of the task to the resulting electromyographic activity is measured to determine the tendon reflex latency, the functional stretch reflex latency, and the voluntary response time in human lower limbs.

Nonlinear stretch reflex interaction during cocontraction
Journal of Neurophysiology, 19931. We investigated the role of stretch reflexes in controlling two antagonist muscles acting at the interphalangeal joint in the normal human thumb. Reflex action was compared when either muscle contracted alone and during cocontraction. 2. The total torque of the flexor pollicis longus (FPL) and extensor pollicis longus (EPL) muscles was measured in ...

Taurine Enhances Stretch Reflex Excitability
2019The purpose of this study was to characterize the effects of taurine (supplementation and acute injection) on the stretch reflex in the ankle muscles, and in particular to compare the effects of chronic taurine supplementation versus acute injection on the muscle tension, amplitude of electromyogram and velocity of muscle response.

Studies of the human stretch reflex
Muscle & Nerve, 2000We recorded the late electromyographic (EMG) responses to predictable and unpredictable stretches of the wrist flexor and extensor muscles during ballistic movement or isometric contractions. We simultaneously recorded the accompanying cerebral responses.

Studies of the human stretch reflex
Journal of the Neurological Sciences, 1968Abstract Measurements of the response to stretch in the triceps surae muscle of 12 normal human subjects are described. Three types of response were observed. One response indicated rheologic factors to be virtually the only determinants of tension, another response indicated rheologic factors predominant at slow speeds with reflex activity at high ...

Voluntary modulation of human stretch reflexes
Experimental Brain Research, 2007It has been postulated that the central nervous system (CNS) can tune the mechanical behavior of a joint by altering reflex stiffness in a task-dependant manner. However, most of the evidence supporting this hypothesis has come from the analysis of H-reflexes or electromyogram (EMG) responses.

Stretch reflexes in human abdominal muscles
Experimental Brain Research, 2004Homonymous and heteronymous reflex connections of the abdominal muscles were investigated by the application of a tap to the muscle belly and observation of surface electromyographic responses. Reflex responses of the following abdominal muscles were investigated both ipsilateral and contralateral to the tap: rectus abdominis (RA), external oblique (EO)

Regulatory actions of human stretch reflex
Journal of Neurophysiology, 19761. The stretch reflex in the elbow flexor musculature was studied in 23 human subjects. The subjects were required to establish an initial force equivalent to 10% maximum at a prescribed initial length; mechanical disturbances delivered at random times increased load force to 15% or reduced it to 5%.
