Pregnancy-related carpal tunnel syndrome.
Clinical and electrophysiological features were studied in 52 cases of carpal tunnel syndrome (CTS) associated with 30 pregnancies. The duration of symptoms was less than 3 months before electrodiagnosis was performed. This study revealed a higher incidence of persistent, painful diurnal symptoms in pregnancy-related CTS (PRCTS) than in idiopathic CTS. PRCTS usually occurs for the first time (de novo) (24/30 cases), in primigravidas (15 cases) as well as multigravidas. The onset of symptoms was in the first or second trimester in 11 women, the third trimester in 12 women, or the post-partum period in seven women. Nerve conduction studies demonstrated evidence of an acute median nerve lesion at the wrist with motor and/or sensory conduction blocks in 20/30 women and severe denervation signs in five women.
