[Value of the cutaneous-plantar reflex in the diagnosis of idiopathic carpal tunnel syndrome].

Introduction: Carpal tunnel syndrome (CTS) is the most common of all focal neuropathies. Its diagnosis is based on a neurophysiological study of the thick motor and sensory fibres in patients with a characteristic clinical picture, although sometimes, in mild cases, this study does not detect the abnormalities. The decision was made to evaluate the small-calibre sympathetic fibres by means of cutaneous-plantar reflex (CPR) in patients with different degrees of idiopathic CTS.
