Effects of static stretching on active muscle stiffness with and without the stretch reflex

open access: yesJournal 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.

Visually-updated hand state estimates modulate the proprioceptive reflex independently of motor task requirements

open access: yeseLife, 2020
Fast signaling from vision and proprioception to muscle activation plays essential roles in quickly correcting movement. Though many studies have demonstrated modulation of the quick sensorimotor responses as depending on context in each modality, the ...

Evidence for Muscle Cell-Based Mechanisms of Enhanced Performance in Stretch-Shortening Cycle in Skeletal Muscle

open access: yesFrontiers 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.

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

open access: yesJournal 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

open access: yesAnnals 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]

open access: yesMotor 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 ...

The Relationship Between Medial Gastrocnemius Lengthening Properties and Stretch Reflexes in Cerebral Palsy

open access: yesFrontiers in Pediatrics, 2018
Stretch reflex hyperactivity in the gastrocnemius of children with spastic cerebral palsy (CP) is commonly evaluated by passively rotating the ankle joint into dorsiflexion at different velocities, such as applied in conventional clinical spasticity ...

Effect of Low-Frequency Vibration on Muscle Response under Different Neurointact Conditions

open access: yesApplied Bionics and Biomechanics, 2019
Stretch reflex is an important factor that influences the biomechanical response of the human body under whole-body vibration. However, there is a lack of quantitative evaluation at lower frequencies.

Neurophysiologic effects of spinal manipulation in patients with chronic low back pain

open access: yesBMC Musculoskeletal Disorders, 2011
Background While there is growing evidence for the efficacy of SM to treat LBP, little is known on the mechanisms and physiologic effects of these treatments.

Can tendon reflexes be elicited by both stretch and vibration in man?

open access: yesBrain and Behavior, 2021
Aim of study When the biceps tendon is tapped, a contraction is elicited in the biceps muscle. This also occurs with tapping of the radial bone, and it has been suggested that vibration is a stimulus for deep tendon reflexes.
