This study evaluated plantar pressure distribution and its clinical significance in patients with diabetic foot toe deformities. Patients with diabetic claw or hammer toe deformities (patient group; n = 30) and healthy subjects without toe deformities (control group; n = 30) were recruited into the study. Plantar pressures in different regions of the foot were measured using the F-scan(®) in-shoe plantar pressure dynamic analysis system. Peak pressures in the hallux and first to fifth metatarsal heads were significantly higher in the patient group compared with the control group. In the midfoot there was no significant difference between the two groups. Hindfoot peak plantar pressures were significantly lower in the patient group compared with the control group. The results indicated that toe deformities in patients with diabetes increased forefoot plantar pressures to abnormally high levels. If plantar pressure is regularly monitored in patients with diabetic foot, toe deformities might be detected earlier and ulceration prevented.
本研究评估了糖尿病足趾畸形患者的足底压力分布及其临床意义。招募了患有糖尿病爪形趾或槌状趾畸形的患者（患者组；n = 30）和无趾畸形的健康受试者（对照组；n = 30）参与本研究。使用F-scan(®)鞋内足底压力动态分析系统测量足部不同区域的足底压力。与对照组相比，患者组中拇趾以及第一至第五跖骨头处的峰值压力显著更高。在足中部，两组之间无显著差异。与对照组相比，患者组的后足峰值足底压力显著更低。结果表明，糖尿病患者的趾畸形会使前足足底压力异常升高。如果对糖尿病足患者定期监测足底压力，可能会更早发现趾畸形并预防溃疡形成。
