The Characteristics and Clinical Significance of Plantar Pressure Distribution in Patients with Diabetic Toe Deformity: A Dynamic Plantar Pressure Analysis

Abstract

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.

Effect of Second Toe-to-Hand Transfer on the Plantar Pressure Distribution of the Donor Foot

“…The software provided with the F-Scan system was used to record the plantar pressure. Similar to the study by Yu et al, 6 five boxes inserted into the plantar pressure distribution areas were used to collect the peak plantar pressure of the hallux, first metatarsal head, second metatarsal head, third to fourth metatarsal head, and fifth metatarsal head. ( Figure 1 ) Measurements were carried out in the following three situations: (1) Intact second toe; (2) Removal of the second toe with the second metatarsal head reserved; and (3) Removal of the second toe and distal third of the second metatarsal.…”

Anatomy and Biomechanical Properties of the Plantar Aponeurosis: A Cadaveric Study

“…An insole sensor film containing 960 independent sensing regions was placed between the plantar foot and the loading platform. The data collection period was scheduled for 8 s, with a collection frequency of 50 frames/s [14]. Five boxes added to the plantar pressure distribution areas were used to collect the peak plantar pressure of the hallux, first metatarsal head, second metatarsal head, third to fourth metatarsal heads, and fifth metatarsal head (Figure 4).…”

A Current Review of Foot Disorder and Plantar Pressure Alternation in the Elderly

“…Diabetic foot accompanied by ulcers often occurred in the big toe and the bottom of the toe, and the average peak plantar pressure time score of patients with plantar ulcer was significantly higher than that of normal people (Tong et al 2011;Yu et al 2011;Fernando et al 2016). Ko et al (Ko et al 2012) found that the walking speed of diabetic patients was significantly lower than that of the control group, resulting in a showed a decrease in walking speed and step length, which was more pronounced on irregular surfaces.…”
