We present three patients with signs and symptoms of meralgia paresthetica (MP ) after long-distance walking and cycling. No other possible causes of MP, such as trauma or exogenous compression, were present. A neuropathy of the lateral f emoral cutaneous nerve was confirmed in all patients with somatosensory evoked p otentials. We propose that conduction block due to local ischemia during repetit ive muscle stretching was the probable cause for the neuropathy.
