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

Frontiers in Physiology, 2021 Force attained during concentric contraction (active shortening) is transiently enhanced following eccentric contraction (active stretch) in skeletal muscle. This phenomenon is called stretch-shortening cycle (SSC) effect.

The stretch reflex and the contributions of C David Marsden
Annals of Indian Academy of Neurology, 2017 The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits.

Detection of stretch reflex onset based on empirical mode decomposition and modified sample entropy
BMC Biomedical Engineering, 2019 Background Accurate spasticity assessment provides an objective evaluation index for the rehabilitation treatment of patients with spasticity, and the key is detecting stretch reflex onset.

Journal of NeuroEngineering and Rehabilitation, 2023 Background Previous studies showed that repetitive transcranial magnetic stimulation (rTMS) reduces spasticity after stroke. However, clinical assessments like the modified Ashworth scale, cannot discriminate stretch reflex-mediated stiffness (spasticity)

Intact thumb reflex in areflexic Guillain Barré syndrome: A novel phenomenon
Annals of Indian Academy of Neurology, 2014 Introduction: Areflexia is one of the cardinal clinical features for the diagnosis of Guillain Barré syndrome. However, some patients may have sluggish proximal muscle stretch reflexes.

Soleus Stretch Reflex during Cycling [PDF]
Motor Control, 2001 The modulation and strength of the human soleus short latency stretch reflex was investigated by mechanically perturbing the ankle during an unconstrained pedaling task. Eight subjects pedaled at 60 rpm against a preload of 10 Nm. A torque pulse was applied to the crank at various positions during the crank cycle, producing ankle dorsiflexion ...

A Method for Quantification of Stretch Reflex Excitability During Ballistic Reaching
IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023 Stretch reflexes are crucial for performing accurate movements and providing rapid corrections for unpredictable perturbations. Stretch reflexes are modulated by supraspinal structures via corticofugal pathways.
