Canes are auxiliary utensils often used by common elders. In nature they must be light, handy to carry and easy to store. Throughout the period of rehabilitation, patients may get support from them and lean on them so that stability and safety could be enhanced while walking. But when elders are walking with a cane, it chances that they might lose balance because of the worn out of the cane pad. Or when walking over wet and slippery ground, owing to the inadequate anti-slippery of the cane pad, the elders might slip or tumble onto ground and get hurt. The purpose of this study is to improve the anti-slippery and anti-erosion effect and stability for the cane pads used by elders. It is expected that more suitable cane pads can be sought lest that elders might suffer the danger resulting from falling onto ground.
Experiment 1: A set of questionnaire was passed to 25 participants who are over 65 years old. Stability, anti-erosion, solidity, and anti-slippery of 7 different cane pads were evaluated. By means of descriptive statistics and one-way ANOVA, the results showed that foot pad with bigger and thicker rubber was given the highest appreciation.
Experiment 2: Anti-erosion test of CNS3217 and Anti-slippery test with ASTM-D1894 Standard were adopted to measure the erosion and friction coefficients for 7 geometric-shaped lined pads. The measurements were statistically analyzed. Rubber material is the better material for anti-erosion and 1/4 round-shaped studded grain is the better material for anti-slippery effect.
Experiment 3: 20 participants over 65 years old have attended the stability test of canes. The experimental conditions included the combinations of three ground surfaces: wood board, grazed tiles, and cement concrete; two cane handles: T shape and crook shape; three cane foot pads: 1/4 round-shaped studded grain, plain without grain, and non-pad; and two environments: dry and wet ground surfaces. The outcome of statistic analysis showed that T-shaped handle and 1/4 round-shaped studded grains have better stability. The subjective evaluation for cane pads showed the same conclusion.
Based on aforementioned experimental conclusions, better material and pad grain for walking canes were found. Hopefully, by this study, more stability and more anti-slippery effect could be increased when elders are walking with canes, and most of personal damages caused by falling onto ground could be prevented. Hence walking safety for elders can be achieved. This study can be referred for multiple purposes by designers or manufacturers of canes as well.
