Revising the stretch reflex threshold method to measure stretch hyperreflexia in cerebral palsy
Frontiers in Bioengineering and Biotechnology, 2022 Hyper-resistance is an increased resistance to passive muscle stretch, a common feature in neurological disorders. Stretch hyperreflexia, an exaggerated stretch reflex response, is the neural velocity-dependent component of hyper-resistance, and has been

Changes in Spinal-Reflex Excitability during Static Stretch and/or Explosive Contraction
Applied Sciences, 2021 To examine individual or combined effects of static stretch and explosive contraction on quadriceps spinal-reflex excitability (the peak Hoffmann’s reflex normalized by the peak motor-response) and the latency times of the Hoffmann’s reflex and motor ...

Current Biology, 2020 Many of us know about stretch reflexes from the doctor's office, when a physician taps the tendon near our kneecap to elicit a quick knee extension. This procedure is used as a diagnostic tool to determine the integrity of the spinal cord and the extension response it elicits may seem otherwise useless. In fact, the tendon tap taps into one aspect of a

Effects of static stretching on active muscle stiffness with and without the stretch reflex
Journal of Physical Fitness and Sports Medicine, 2020 The purpose of the present study was to examine acute changes in active muscle stiffness with and without the stretch reflex following static stretching.

Journal of Functional Morphology and Kinesiology, 2022 Unaccustomed or strenuous eccentric exercise is known to cause delayed-onset muscle soreness. A recent hypothesis postulated that mechano-energetic microinjury of the primary afferent sensory neuron terminals in the muscle spindles, namely a transient ...

Sensors, 2023 Spasticity might affect gait in children with cerebral palsy. Quantifying its occurrence during locomotion is challenging. One approach is to determine kinematic stretch reflex thresholds, usually on the velocity, during passive assessment and to search ...
