Abstract

Study design:Experimental study.Objectives:To study the role of surface temperature as an adjunct to motor evoked potentials (MEPs) in rabbit spinal cord injury (SCI) model.Setting:Department of Orthopedics, Korea University Guro Hospital, Seoul, Korea.Methods:Rabbits (n=18) were divided into Complete (n=9) and Incomplete (n=9) SCI groups. Complete SCI was defined as being non-responsive to a wake-up test with loss of MEPs after transection of spinal cord. Incomplete SCI was defined as being responsive to a wake-up test with significant attenuation (≥80%) of MEPs after impaction on spinal cord. Surface temperature of upper and lower extremities, core temperature and MEPs signals were checked before, during and after SCI for 20 min. A wake-up test was conducted and spinal cord was histologicaly evaluated.Results:Experimental conditions between the two groups were statistically similar (P>0.005 for all values). After SCI, upper extremity temperatures did not change in either group (P>0.005); however, the surface temperature of the lower extremities in the Complete SCI Group elevated to 1.7±0.5 °C in comparison to 0.5±0.1 °C in the Incomplete SCI Group (P
