A variety of seemingly diverse pain syndromes are characterized by movement-induced pain radiating in the distribution of a peripheral nerve or nerve root. This could be explained by the induction of ectopic mechanical sensitivity in intact sensory axons. Here we show that inflammation led to mechanical sensitivity of the axons of a subset of mechanically(More)
After injuries to the musculoskeletal system, peripheral nerve axons are exposed to numerous inflammatory mediators, including tumor necrosis factor-alpha (TNF). Exposure of sensory axons to TNF can cause behavioral hypersensitivity in the peripheral innervation territory of the affected axons. The hypothesis that TNF activates nociceptor axons was tested(More)
BACKGROUND This study determined the effect of intrathecally administered cholinesterase inhibitors, edrophonium and neostigmine, on nerve injury-induced, touch-evoked allodynia and identified the pharmacologic characteristics of this action. METHODS Rats were prepared with tight ligation of the left L5 and L6 spinal nerves and with lumbar intrathecal(More)
BACKGROUND Experimental studies have shown that gabapentin can reduce neuronal injury in the setting of cerebral ischemia, but the mechanisms have not yet been clearly determined. This study was conducted to determine whether gabapentin pretreatment altered expression levels of heat shock protein 70 and reduced acute phase neuronal injury in rats subjected(More)
Epidural fibrosis is a contributing factor to the persistent pain that is associated with failed back surgery syndrome (FBSS) and other pathophysiologies, particularly as it inhibits the passage of regional medications to areas responsible for pain. Therefore, effective mechanical detachment of epidural fibrosis can contribute to pain reduction and improve(More)
