Title Frequency dependence of hand-arm vibration on palmar sweating response
Bibliographic information Oct. 2002, Vol.28, No.5, p.324-327. Illus. 13 ref.
Abstract In this study on the effects of hand-arm vibration frequency on palmar sweating, sweating was measured on the right palm of six healthy men, before and during exposure of the left palm to various vibration frequencies during three minutes. The control condition consisted of grasping a handle without vibration. As an indicator of the state of activation of the central nervous system, plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) was measured before and immediately after each vibration exposure. Each vibration condition induced a palmar sweating response. Among the six vibration conditions, frequencies of 125Hz and 63Hz caused large palmar sweating responses compared with those of 315Hz and the control condition. Plasma MHPG did not increase significantly after either kind of vibration exposure.
