Measurement of muscle oxygenation during exercise by NIRS graded the severity of IC in diabetic patients more accurately than resting ABPI. An abstract based on this paper was presented to the symposium of the 18th World Congress of the International Union of Angiology in Tokyo, Japan, September 1998

muscle oxygen saturation measurement by SRS can be used clinically to provide objective information regarding the severity of IC.

The low skin perfusion pressure at rest in patients with secondary Raynaud's phenomenon suggested the presence of obstructive arterial lesions. The marked pressure decrease in all Raynaud's patients after local cold exposure might be due to vasospasm of the microvasculature in the digits. These results indicate that the measurement of laser Doppler skin perfusion pressure is valuable in the diagnosis of Raynaud's phenomenon.
