Plantar pressures in diabetes with no known neuropathy (无神经病变的糖尿病患者的足底压力)

Background The aim of the present study was to investigate associations of arch type and gender with plantar pressure distribution in non‐diabetic subjects and subjects with type 2 diabetes mellitus (T2DM) without peripheral neuropathy (PN). Methods Plantar pressures were recorded in 62 subjects with T2DM but without PN (mean [±SD] age 63.6 ± 7.6 years, body mass index [BMI] 24.3 ± 2.9 kg/m2, and duration of diabetes 7.0 ± 3.0 years) and in 63 non‐diabetic adults (62.5 ± 8.5 years of age; BMI 22.4 ± 2.5 kg/m2) in static stance using a foot analyzer. Data were collected from both feet and were analyzed for their association with disease, arch type, and gender using the Mann–Whitney U‐test and Chi‐squared test, respectively. Results There were significant differences in plantar pressures between the left and right feet in T2DM subjects, regardless of gender, and their metatarsal heads were overloaded. There were poor correlations between the overloaded plantar pressures and both foot arch and gender for all diabetic subjects. However, there were no differences in pressures at different zones between the diabetic and non‐diabetic subjects. Conclusions There were no differences in plantar pressures between non‐diabetic and T2DM subjects without PN. Furthermore, there were no significant correlations between plantar pressures in diabetic subjects and either arch type or gender. However, there were significant differences in plantar pressures between the right and left feet. 摘要 背景 本研究的目的是在非糖尿病受试者以及无周围神经病变（PN）的2型糖尿病（T2DM）受试者中调查足弓类型、性别与足底压力分布之间的关系。 方法 62名没有PN的T2DM受试者（平均[±SD]年龄为63.6±7.6 岁，体重指数为24.3±2.9 kg/m2，糖尿病病程为7.0±3.0 年）以及63名非糖尿病成年人（年龄为62.5±8.5 岁；BMI为22.4±2.5 kg/m2）使用足部分析仪在静止的状态下测定足底压力。从双侧足部收集数据并且分别使用Mann–Whitney U‐检验与Chi‐squared检验来分析它们与疾病、足弓类型以及性别之间的关系。 结果 不管何种性别，T2DM受试者左足与右足之间的足底压力都有显著性的差异，并且他们的跖骨头都负荷过重。所有糖尿病受试者超负荷的足底压力与足弓以及性别之间都只有很弱的相关性。然而，在糖尿病与非糖尿病受试者之间，足底不同部位的压力都没有差异。 结论 在非糖尿病与未合并PN的T2DM受试者之间，足底压力没有差异。此外，糖尿病受试者的足底压力与足弓类型或者性别之间都没有显著的相关性。然而，左足与右足之间的足底压力有显著性的差异。
