Abstract:

The purpose of the present study was to investigate the effect of a range of water temperatures Tw from 15 to 36 C on the shape of the tissue temperature profile of the resting human forearm at thermal stability. Tissue temperature Tt was continuously monitored by a calibrated multicouple probe during 3 hours immersion of the forearm. The probe was implanted approximately 9 cm distal from the olecranon process along the ulnar ridge. Tt was measured every 5 mm, from the longitudinal axis of the forearm determined from computed tomography scanning to the skin surface. For all temperature conditions, the temperature profile inside the limb was linear as a function of the radial distance from the forearm axis p 0.01 when the temperature data were averaged for the different groups at each water temperature tested. However, interindividual variability regarding the shape of the temperature profile was observed. A linear profile was observed in 50 of the experiments, a profile with convex curvature in 30, and a profile with concave curvature in the remaining 20. No significant relationship was observed between the occurrence rate of the different shapes of temperature profile and the water temperature.
