The Effects of Silver Spike Point Therapy on Peripheral Circulatory Function in Workers Exposed to Hand-Arm Vibration / 日本温泉気候物理医学会雑誌

ABSTRACT

The purpose of this study was to examine the effects of silver spike point (SSP) therapy on peripheral circulatory function in workers exposed to hand-arm vibration by analyzing the second derivative of photoplethysmogram (SDPTG). Seventy-seven male subjects including public service workers and forestry workers volunteered for the present study. After the SSP therapy on LI4 (Hege) and LI10 (Shousanli) at 1Hz for 10 minutes, the SDPTG-index was significantly increased among the subjects whose SDPTG-index was below the 50th percentile curve of the normal aging curve. The result suggests that the SSP therapy is useful in the improvement of peripheral circulatory function in workers exposed to hand-arm vibration.
