目的调查行走前后地板抗滑性主观评量的影响因素及二者之间的关系。方法设计了4因子实验。实验因子包含地板粗糙度、地板表面情况、鞋底材质和照明情况。被试在步道待试区对地板感知抗滑性给出1(非常滑)-5(不滑)的评分;待走过实验步道后,再次对地板感知抗滑性给出评分,并对自觉滑动感(PSOS)做出评分。运用SAS分析软件对得到数据进行统计分析。结果地板粗糙度、地板表面情况和照明水平对实验前主观抗滑性存在显着的影响(P<0.0001);鞋底材质、地板粗糙度和地板表面情况对实验后主观抗滑性及自觉滑动感(PSOS)存在显着的影响;地板粗糙度与实验前(r=0.38,P<0.0001)与实验后(r=0.52,P<0.0001)的主观抗滑性均为正相关;实验后的主观抗滑性与自觉滑动感为高度负相关(r=-0.84,P<0.0001)。结论行走前地板主观抗滑性显著的受地板粗糙度、地板表面情况、照明水平的影响;行走后地板主观抗滑性显著的受鞋底材质、地板粗糙度和地板表面情况的影响。
Objective To investigate the influencing factors of subjective evaluation of floor skid resistance before and after walking and the relationship between them. Methods Four factors were designed. Experimental factors include floor roughness, floor surface conditions, sole material and lighting conditions. The test score of 1 (very slippery) -5 (not slippery) was given to the floor perceived skid resistance in the trial area of the trail. After going through the experimental trail, the score of floor perceived skid resistance was given again, Sliding sense (PSOS) to make a score. Using SAS analysis software to get the data for statistical analysis. Results The roughness of the floor, the surface of the floor and the level of illumination had a significant effect on the subjective skid resistance before the experiment (P <0.0001). The sole material, the floor roughness and the floor surface had no significant effect on the subjective skid resistance and the conscious sliding sensation (PSOS). The roughness of the floor was positively correlated with the subjective skid resistance (r = 0.38, P <0.0001) before and after the experiment (r = 0.52, P <0.0001) Skid resistance and self-conscious slippage were highly negatively correlated (r = -0.84, P <0.0001). Conclusions The subjective skid resistance of the floor before walking is significantly affected by the roughness of the floor, the surface of the floor and the level of illumination. The subjective skid resistance of the floor after walking is significantly affected by the material of the sole, the roughness of the floor and the surface of the floor.
