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).fter about 5 days in zero gravity, for instance in orbit around Earth, the h-reflex diminishes significantly. It is generally assumed that this is due to a marked reduction in the excitability of the spinal cord in zero gravity.
You may get a weak response if the neuropathy is not complete. The reason is that the h-reflex is evoked by stimulating the (large diameter) group Ia spindle afferents in peripheral nerves, usually the tibial nerve.
