Fourteen subjects sat for 20 minutes either with their legs dangling and unsupported, or supported on a flat surface. Foot and calf skin surface temperature measures were taken using infrared thermography. Laboratory climate conditions were recorded. Results showed a significant decrease in both foot and calf skin surface temperatures (-0.7°C and 0.2°C respectively) when sitting with the feet supported compared to sitting with the legs dangling but stationary. Results suggest that although foot support may be important, if the supported legs are stationary this may increase venous stagnation. Strategies for periodically moving the supported feet should be considered.
