To compare the thickness and stiffness of plantar soft tissues between people with diabetic peripheral neuropathy (DPN) and healthy subjects.
Cross-sectional study.
University research laboratory.
Subjects with DPN (n=70 [35 men, 35 women]; mean age ± SD, 65.4 ± 8.6y) and healthy control subjects (n=54 [12 men, 42 women]; mean age ± SD, 57.9 ± 6.1y) were recruited.
Not applicable.
The thickness and stiffness of the plantar soft tissues were measured by the tissue ultrasound palpation system over the pulp of the big toe (BT), first metatarsal head (MTH), second MTH, and the heel.
No significant difference in the thickness of the plantar soft tissues was found in any measurement site between the diabetic group and control group. The plantar soft tissues of the DPN group were significantly stiffer than those of the control group at the BT (85.29 kPa vs 50.49 kPa), first MTH (96.29 kPa vs 62.05 kPa), second MTH (84.77 kPa vs 52.93 kPa), and the heel (65.62 kPa vs 44.95 kPa) (all P<.01).
People with DPN tend to have stiffer plantar tissues than do healthy control subjects. The stiffer plantar soft tissues may reduce the cushioning effects of the foot during walking for people with DPN.
比较糖尿病周围神经病变（DPN）患者与健康受试者足底软组织的厚度和硬度。
横断面研究。
大学研究实验室。
DPN 患者（n=70[男 35 例，女 35 例]；平均年龄±标准差，65.4±8.6 岁）和健康对照组（n=54[男 12 例，女 42 例]；平均年龄±标准差，57.9±6.1 岁）。
无。
使用组织超声触诊系统测量大脚趾（BT）、第一跖骨头（MTH）、第二 MTH 和足跟处足底软组织的厚度和硬度。
糖尿病组和对照组在任何测量部位的足底软组织厚度均无显著差异。DPN 组的足底软组织在 BT（85.29 kPa 比 50.49 kPa）、第一 MTH（96.29 kPa 比 62.05 kPa）、第二 MTH（84.77 kPa 比 52.93 kPa）和足跟（65.62 kPa 比 44.95 kPa）处均明显硬于对照组（均 P<.01）。
DPN 患者的足底组织往往比健康对照组更硬。更硬的足底软组织可能会降低 DPN 患者行走时足部的缓冲效果。
