Changes in electrical perceptual threshold in the first 6 months following spinal cord injury.

Objectives: To investigate the use of electrical perceptual threshold (EPT) testing to follow the natural history of sensory progression after complete and incomplete acute spinal cord injury (SCI) and to compare EPT changes with the American Spinal Injuries Association (ASIA) Impairment Scale (AIS).

Study Design: Prospective descriptive study.

Methods: ASIA examination and EPT testing was performed on 17 patients (7 AIS A, 10 AIS B-D), within 1, 3, and 6 months after acute SCI.

Electrical perceptual threshold testing: a validation study.

Background/objective: To investigate inter-rater and intra-rater reliability of electrical perceptual threshold (EPT) testing in assessing somatosensory function in healthy volunteers.

Study Design: Prospective experimental.

Setting: Hospital-based spinal cord injuries unit.
