A fundamental study of the pressure ulcers prevention by decline of the skin friction force.

压力性溃疡可以简单地由长期施加压力引起;然而，摩擦、剪切和湿度会加剧发病的风险。在以前的研究中已经证明了皮肤摩擦力的个体差异;因此，在本研究中，摩擦力与皮肤固有水分、皮脂和颗粒含量的相关性。对20多岁男性6例、女性17例背部皮肤的摩擦力、纹理、水分和皮脂含量进行了测定。虽然摩擦力与皮肤含水量、纹理无关，但摩擦力与皮脂含量相关。

Pressure ulcers can arise simply from long-term application of pressure ; however, the risk of onset is exacerbated by friction, shear and humidity. Individual variation in skin friction force has been demonstrated in previous studies ; therefore, in the present study, the relevance of friction force with the intrinsic moisture, sebum and grain content of the skin. The sample of male were 6 and female were 17 in their 20s and the friction force, grain, moisture and sebum content of the skin in the dorsal region were measured. Although friction force has no relevance to moisture content, skin grain, friction force has relevance to sebum content.
