    OBJECTIVE--To examine the possibility that subclinical damage may persist after clinical recovery from neurological decompression illness. METHODS--The neuraxes of 71 divers with medical histories of neurological decompression illness and 37 non-diver controls were examined by recording the somatosensory evoked potentials produced on stimulation of the posterior tibial and median nerves. RESULTS--Although the tests gave some objective support for the presence of "soft" residual neurological symptoms and signs, no evidence was given for the presence of subclinical damage. CONCLUSIONS--The contention that neurological damage persists after full clinical recovery from the neurological decompression illness was not supported.
