Qué (quién) es H-reflex - definición


H-reflex         
MUSCLE RESPONSE
H-Reflex; H Reflex; H reflex; H response; H-response; M-wave
The H-reflex (or Hoffmann's reflex) is a reflectory reaction of muscles after electrical stimulation of sensory fibers (Ia afferents stemming from muscle spindles) in their innervating nerves (for example, those located behind the knee). The H-reflex test is performed using an electric stimulator, which gives usually a square-wave current of short duration and small amplitude (higher stimulations might involve alpha fibers, causing an F-wave, compromising the results), and an EMG set, to record the muscle response.
Flinching         
  • An example of reflex reversal is depicted. Activating the same spinal reflex pathway can cause limb flexion while standing, and extension while walking.

Withdrawal reflex         
SPINAL REFLEX
Pain withdrawal reflex; Pain Withdrawal Reflex; Nociceptor reflex; Flexor reflex; Flexion reflex; Nociceptive flexion reflex; RIII reflex; Nociceptive flexion response
The withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus.
