Abstract

Background Declines in foot somatosensory function can negatively impact balance and daily activities, particularly in older adults and individuals with neurological conditions. Despite this, effective physical therapeutic interventions to improve foot sensory function are limited. This study assessed the effects of targeted foot somatosensory training on plantar sensory function in healthy young adults. Methods Thirty-three healthy young adults (mean age 21.2 ± 0.7 years) were randomly assigned to one of three groups: (1) Discrimination group, (2) Attention group, or (3) Control group. The Discrimination group performed spatial attention tasks to identify weight positions on an instability board; the Attention group focused on timing tasks; and the Control group watched a video. Tactile pressure sensitivity and two-point discrimination of the plantar surface were measured before and after the intervention. Statistical analyses included Wilcoxon signed-rank tests and two-way repeated measures of analysis of variance (ANOVA). Results No significant differences were found in tactile pressure sensitivity. However, two-point discrimination thresholds for the big toe and the ball of the little toe were significantly reduced in the Discrimination group, indicating enhanced sensitivity. Conclusion Foot sensory training, particularly through discrimination tasks, may effectively improve plantar sensory function, suggesting potential clinical applications in individuals with sensory impairments.

足部体感训练对足底体感功能的影响。
足部体感功能的下降会对平衡和日常活动产生负面影响,特别是在老年人和神经系统疾病患者中。尽管如此,改善足部感觉功能的有效物理治疗干预是有限的。本研究评估了有针对性的足部体感训练对健康年轻人足底感觉功能的影响。方法33名健康青年(平均年龄21.2±0.7岁)随机分为3组:(1)辨别组、(2)注意组和(3)对照组。辨别组执行空间注意任务,以确定不稳定板上的重量位置;注意组专注于定时任务;对照组则观看一段视频。测量干预前后足底表面触觉压力敏感性和两点辨别力。统计分析包括Wilcoxon sign -rank检验和双向重复方差分析(ANOVA)。结果两组患者的触觉压力敏感性无显著差异。然而,在discrimination组中,大脚趾和小脚趾球的两点辨别阈值显著降低,表明敏感性增强。结论足部感觉训练,特别是鉴别训练,可有效改善足底感觉功能,在感觉障碍患者中具有潜在的临床应用价值。
