Nerve growth factor-induced muscle hyperalgesia facilitates ischemic contraction-evoked pain.
Authors
Abstract
Intramuscular injection of Nerve Growth Factor (NGF) may influence the responsiveness of active chemo-sensitive channels affecting muscle pain sensitivity. This double-blinded crossover study in healthy humans assessed contraction-evoked pain responses and pain sensitivity during acute ischemia in the tibialis anterior (TA) muscle before and 24h after five distributed NGF injections (1μg, 4 cm interval) compared with control injections (isotonic-saline).
