Systemic lupus erythematosus may have an early effect on peripheral nerve function in patients without clinical or electrophysiological neuropathy: comparison with age- and gender-matched controls.

Asymptomatic electrophysiological peripheral neuropathy is described in systemic lupus erythematosus (SLE) patients. To determine if SLE could have an even earlier effect on peripheral nerve function even before the development of electrophysiological abnormalities, we compared nerve conduction studies (NCS) of SLE patients without electrophysiological or clinical peripheral neuropathy with healthy controls. Consecutive SLE patients without clinical neuropathy (or other known causes of neuropathy) underwent sensory and motor NCS of all four limbs.

Effects of demographic and physical factors on nerve conduction study values of healthy subjects in a multi-ethnic Asian population.

Introduction: We investigated the effects of demographic and physical factors on nerve conduction studies (NCS) in a multi-ethnic Asian population.

Methods: One hundred sixty-six healthy Malaysians of different ethnicities (51.2% women, aged 21-77 years) underwent NCS using a standard protocol.
