Operant down-conditioning of the soleus H-reflex in people after stroke [PDF]

Frontiers in Rehabilitation Sciences, 2022
Through operant conditioning, spinal reflex behaviors can be changed. Previous studies in rats indicate that the sensorimotor cortex and corticospinal tract are essential in inducing and maintaining reflex changes induced through conditioning.

Differences in Trapezius Muscle H-Reflex between Asymptomatic Subjects and Symptomatic Shoulder Pain Subjects [PDF]

Sensors, 2023
In chronic shoulder pain, adaptations in the nervous system such as in motoneuron excitability, could contribute to impairments in scapular muscles, perpetuation and recurrence of pain and reduced improvements during rehabilitation.

The H-reflex study of the flexor carpi radialis muscle in healthy individuals [PDF]

Frontiers in Neurology
ObjectiveThis study aimed to investigate the physiological and anatomical factors influencing the flexor carpi radialis (FCR) H-reflex and to establish reference values for FCR H-reflex parameters in relation to these factors.MethodsThe FCR H-reflexes ...

Reliability of transcranial magnetic stimulation and H-reflex measurement during balance perturbation tasks [PDF]

Frontiers in Physiology, 2022
Following ankle movement, posterior balance perturbation evokes short- (SLR ∼30–50 ms), medium- (MLR ∼50–60 ms), and long-latency responses (LLR ∼70–90 ms) in soleus muscle before voluntary muscle contraction.

Effect of static stretching duration on modulation of H‐reflex and tendon‐reflex excitability of the soleus muscle in young men [PDF]

Physiological Reports
Stretching‐induced impairments of muscle performance are attributed to neural adaptations and mechanical changes. Inhibition of muscle spindle sensitivity appears to have long‐lasting effects after stretching.

Absence of Neuroplastic Changes in the Bilateral H-Reflex Amplitude following Spinal Manipulation with Activator IV [PDF]

Medicina, 2022
Background and Objectives: Chiropractic spinal manipulation is an alternative medical procedure for treating various spinal dysfunctions. Great interest exists in investigating its neuroplastic effects on the central nervous system. Previous studies have

Adaptive gait responses to varying weight‐bearing conditions: Inferences from gait dynamics and H‐reflex magnitude [PDF]

Experimental Physiology
This study investigates the effects of varying loading conditions on excitability in neural pathways and gait dynamics. We focussed on evaluating the magnitude of the Hoffman reflex (H‐reflex), a neurophysiological measure representing the capability to ...

Comparative study of soleus H-reflex in normal humans and in patients with neuropathies

National Journal of Physiology, Pharmacy and Pharmacology, 2022
Background: The H-reflex derived its name from Hoffman. Hoffmann reflex is an electrically induced reflex analogous to the mechanically induced spinal stretch reflex.

Impact of Arm Length and Body Mass Index on Abductor Pollicis Brevis (APB) H-Reflex among Females [PDF]

Journal of Clinical and Diagnostic Research, 2019
Introduction: Hoffmann reflex (H-reflex) is an electrically induced reflex analogous to the mechanically induced spinal stretch reflex. H-reflex is useful clinically to diagnose nerve root lesions, particularly involving S1 radiculopathy and in proximal ...
