Modulations of stretch reflex by altering visuomotor contexts [PDF]

Frontiers in Human Neuroscience
Various functional modulations of the stretch reflex help to stabilize actions, but the computational mechanism behind its context-dependent tuning remains unclear.

Temporal shift in task factor influence across the stretch reflex. [PDF]

PLoS ONE
Mechanical perturbations applied to the arm can elicit reflexive actions. These rapid corrective responses include the stretch reflex, which consists of different components: the short-latency reflex (SLR) and the early and late long-latency reflex (LLR).

Soleus stretch reflex during cycling [PDF]

, 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.

Ultrasound-Derived Stretch Reflex Threshold Estimation Using Tendon-to-Bone Distance During Tendon Tapping in Post-Stroke Spasticity [PDF]

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Spasticity assessment after stroke requires objective measures of stretch reflex excitability, yet clinically practical and structurally interpretable approaches for identifying stretch reflex thresholds (SRTs) remain limited.

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.

Stretch signal and muscle state dependence of the tonic stretch reflex [PDF]

, 2000
When active skeletal muscle is stretched, it generally responds with a contraction which resists the stretch. This response is termed the muscle stretch reflex.

Testing spasticity mechanisms in chronic stroke before and after intervention with contralesional motor cortex 1 Hz rTMS and physiotherapy

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.

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.

Treatment Response to Botulinum Neurotoxin-A in Children With Cerebral Palsy Categorized by the Type of Stretch Reflex Muscle Activation

Frontiers in Neurology, 2020
While Botulinum NeuroToxin-A (BoNT-A) injections are frequently used to reduce the effects of hyperactive stretch reflexes in children with cerebral palsy (CP), the effects of this treatment vary strongly.
