    The frequency of peripheral nerve involvement in sarcoidosis is uncertain. To determine how often peripheral nerves are affected in the absence of symptoms, electromyography was performed on 29 sarcoid patients and 29 age-matched controls. Nineteen sarcoid patients, compared to two controls, had abnormally low sensory amplitudes in one or more nerves, and the mean sensory amplitudes for median, ulnar, and sural nerves were lower in the patient than in the controls. Subclinical mononeuropathy multiplex appears to be common in sarcoidosis.
