Abstract

Sciatica with or without nerve injury can present with weakness. Those with sacroiliitis and greater trochanteric pain syndrome commonly have lower extremity weakness. In these cases, weakness may be mediated by nociceptive signals from damaged or inflamed joints, a concept called arthro-genic inhibition. Sensory loss is most often a sign of neuropathic sciatica, but it can also occur in somatic referred sciatica.
