Taurine Enhances Stretch Reflex Excitability

2019
The 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, 2000
We 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, 1968
Abstract 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, 2007
It 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, 2004
Homonymous 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, 1976
1. 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%.

Nonlinear identification of stretch reflex dynamics

Annals of Biomedical Engineering, 1988
The objective of this study was to use nonlinear identification techniques to study the dynamics of stretch reflexes in the human calf muscles (gastrocnemius-soleus). Stochastic perturbations of ankle position were applied while subjects maintained a constant, tonic contraction of gastrocnemius-soleus.

STRETCH REFLEXES OF THE NORMAL INFANT

Developmental Medicine & Child Neurology, 1986
Tendon-jerk reflexes were tested in normal, fullterm infants aged one to four days. EMGs were recorded from gastrocnemius-soleus and tibialis anterior muscles. Reflex-like EMGs were evoked when tapping sites which should not excite the muscles from which that activity is recorded--this included the simultaneous activation of antagonistic muscles by a ...

Stretch Reflexes and Parkinsonian Tremor

1987
By coupling human limbs to a machine, which drives a single joint through sinusoidal flexion-extension movements, it is often possible to entrain the resting tremor of Parkinson's disease. Entrainment is most likely to occur when the imposed movement is large in amplitude and close in frequency to the spontaneous tremor.

Stretch reflex and H-reflex during human walking

Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002
The H-reflex and the stretch reflex modulation during gait have both been described in the literature as high during the stance phase and suppressed throughout the swing phase. To illuminate the difference between the two methodologies, both types of reflexes was evoked in the same subjects within the same experiment.
