机械振动按摩器对正常人局部皮肤温度影响的红外热像观察

Effect of Vibration Massage Apparatus on Skin Temperature in Healthy Adults by Infrared Thermography

目的用红外热像仪观察机械振动按摩器对人体局部温度的影响,从客观数据上证实其有效性,为振动按摩器最佳振动频率的确定奠定基础。方法上海中医药大学的30名健康大学生先后接受机械振动按摩器的空置和振动两种操作,用红外热像仪分别于操作前0 s、操作3 min后即刻、撤离仪器后1,2,3,4 min和5 min观察受试者以心俞为中心的手掌大小区域的温度的动态变化,并用分析软件处理相关温度数值,将结果进行统计学分析。结果①不同测量时间对受试者局部温度有影响(P<0.05),空置组中温度升高在空置3 min后即刻尤为明显,尔后温度呈逐渐下降趋势,而振动组中随着时间的增加,背部温度不断升高,在振动后撤离仪器3 min达到峰值;②空置组和振动组都能使局部皮肤温度有不同程度的升高,但振动组比空置组产热效应更显著,而且更为持久。结论机械振动按摩器在频率为900次/min的情况下能使人体局部温度明显升高,且效果持久,充分证实了它的有效性,同时为机械振动按摩器的最佳振动频率的确定奠定了基础。

Objective To observe the effect of vibration massage apparatus on skin temperature by infrared thermal imaging system . Methods 30 healthy students of Shanghai university of TCM accepted two operations of vibration massage apparatus - non - vibration and vibration . The temperature diversity was obseved at different time ： before operation , after 3min operation, after evaluating apparatus 1, 2, 3,4,5 rain by infrared thermal imaging system . The image was dealt with analysis system and data was statistically anlyzed. Results ①In non - vibration group, the peak of temperature appeared at operation 3min; in vibration group, the temperature were increasing gradually as the peak appeared at evacuating 3min . ②vibration group had better significant and persistent calorigenic effect than non - vibration group. Conclusion Vibration massage apparatus has the validity of heightening temperature. This experiment established the foundation of research about defining the optimal frequency of vibration massage apparatus.
