To compare the incidence and nature of ‘neurophysiological events’ identified, The IOM wave-recordings, event-logs and reports of all spinal deformity cases conducted by a team of clinical physiologists from April to June 2009 (Group 1) were reviewed retrospectively by the same, experienced clinical neurophysiologist, (MG). Interventions were then agreed. The first was to alter the IOM report document to drop down menus. The second was to arrange a series of teaching sessions for the clinical physiologists on a variety of aspects of IOM. Finally during these teaching sessions recent cases were brought to review in an informal setting to discuss. Following implementation of the interventions a further review from April to June 2010 (Group 2) was carried out in the same manner. The clinical physiologists did not know the time periods over which the review would be taking place.Purpose
