The vertical forces acting on the sole of the foot in walking have been measured in 24 diabetic patients with neuropathic ulceration of the foot using a load-sensitive surface divided into 128 load cells, and compared with those in two groups of controls: (a), 21 diabetic patients with peripheral neuropathy but no ulceration and (b) 47 normal individuals. The results showed that the patients with neuropathic ulceration were significantly heavier, that diabetic patients with neuropathy, with or without ulceration, transmitted proportionally less force through the toes than normal individuals, and showed a medial shift of the force transmitted through the metatarsal heads. All plantar ulcers occurred at the site of maximum loading. The absolute force at the site of maximum loading was significantly greater in the patients with ulcers than in both control groups, through there was a considerable overlap. A significant difference remained even when the absolute force had been corrected for differences in toe loading and body weight, indicating that a further factor (or factors) must contribute to the development of these localized areas of high loading.
使用一个分为128个测力单元的负载敏感表面,对24例患有足部神经性溃疡的糖尿病患者行走时作用于足底的垂直力进行了测量,并与两组对照组进行了比较:(a) 21例患有周围神经病变但无溃疡的糖尿病患者,以及(b) 47名正常个体。结果显示,患有神经性溃疡的患者体重明显更重,患有神经病变的糖尿病患者,无论有无溃疡,通过脚趾传递的力比正常个体成比例地少,并且通过跖骨头传递的力出现向内侧偏移。所有足底溃疡均发生在最大负荷部位。溃疡患者最大负荷部位的绝对力明显高于两个对照组,尽管存在相当大的重叠。即使在对脚趾负荷和体重差异进行绝对力校正后,仍存在显著差异,这表明还有一个或多个其他因素必定促成了这些局部高负荷区域的形成。
