To examine validity and test-retest reliability of a sensory test developed to evaluate ability of elderly subjects with/out a stroke to discriminate between textures with the sole of their foot.
Subjects poststroke, old adults and young subjects were tested twice. Twelve materials relevant to foot function (e.g., gravel, sand) were used. Blindfolded subjects were requested to discriminate with the sole of each foot one outstanding texture among three textures presented in each of 12 subtests. ANOVA, ICC and Bland-Altman tests were used to determine group/leg differences and test-retest reliability.
Discrimination ability of the involved lower extremity poststroke is significantly reduced. Ability in individuals with no neurological impairment is age related. Good test-retest (ICC = 0.81) reliability was demonstrated for the impaired foot of subjects poststroke. The 95% repeatability ranges were age related with the highest range demonstrated for the involved foot poststroke. A significant fair negative correlation was demonstrated between texture discrimination ability and tactile detection threshold measured by Semmes-Weinstein monofilaments for the involved foot in poststroke subjects.
This newly developed assessment tool demonstrates concurrent and known-groups validity and is reliable for determining texture discriminative ability of the foot in individuals post-stroke and in older adults with no neurological impairment. Implications for rehabilitation The texture discrimination test presented here is a valid and reliable tool, providing quantitative assessment of sensory function at the sole of the foot in older adults with no neurologic deficits and in subjects poststroke. Lower extremity texture discrimination test is easy to administer in the clinic and might suggest directions for individually tailored, lower extremity, sensory retraining protocols.
检验一种感官测试的有效性和重测信度，该测试旨在评估有无中风的老年受试者用脚底区分不同质地的能力。
对中风后受试者、老年人和年轻人进行了两次测试。使用了12种与足部功能相关的材料（如砾石、沙子）。要求蒙眼受试者用每只脚的脚底在12个分测试中的每个测试所呈现的三种质地中辨别出一种突出的质地。采用方差分析、组内相关系数（ICC）和布兰德-奥特曼检验来确定组间/腿间差异和重测信度。
中风后患侧下肢的辨别能力显著降低。无神经损伤个体的能力与年龄有关。中风后受试者患侧足部显示出良好的重测信度（ICC = 0.81）。95%的重复性范围与年龄有关，中风后患侧足部的范围最大。中风后受试者患侧足部的质地辨别能力与用Semmes-Weinstein单丝测量的触觉检测阈值之间存在显著的中度负相关。
这种新开发的评估工具具有同时效度和已知组效度，对于确定中风后个体和无神经损伤的老年人足部的质地辨别能力是可靠的。康复意义 此处介绍的质地辨别测试是一种有效且可靠的工具，可对无神经功能缺损的老年人和中风后受试者脚底的感觉功能进行定量评估。下肢质地辨别测试在临床中易于实施，可能为个体化定制的下肢感觉再训练方案提供指导方向。
