    ObjectivesTo describe sensations evoked by painful or repetitive stimulation below injury level in patients with a clinically complete (American Spinal Injury Association, ASIA Grade A) spinal cord injury (SCI).Material And MethodsTwenty-four patients (11 with central neuropathic pain and 13 without pain) with a traumatic SCI above the tenth thoracic vertebra were examined using quantitative sensory testing, MR imaging, and somatosensory evoked potentials (SEP).ResultsPainful (pressure, pinch, heat or cold) or repetitive (pinprick) stimuli elicited vague localized sensations in 12 patients (50%). Pain, spasticity, and spasms were equally seen in SCI patients with or without localized sensations. SEP and MRI did not differentiate between these two groups.ConclusionThe present study suggests retained sensory communication across the injury in complete SCI, i.e. 'sensory discomplete' SCI.
