Before And After

Background: Offloading devices for diabetic foot ulcers (DFU) generally restrict exercise. In addition to traditional health benefits, exercise could benefit DFU by increasing blood flow and acting as thermotherapy. This study functionally evaluated a cycling cleat designed for forefoot DFU. Methods: Fifteen individuals at risk of developing a DFU used a recumbent stationary bicycle to complete one 5-minute cycling bout with the DFU cleat on their study foot and one 5-minute bout without it. Foot stress was evaluated by plantar pressure insoles during cycling. Laser Doppler perfusion monitored blood flow to the hallux. Infrared photographs measured foot temperature before and after each cycling bout. Results: The specialized cleat significantly reduced forefoot plantar pressure (9.9 kPa versus 62.6 kPa, P < .05) and pressure time integral (15.4 versus 76.4 kPa*sec, P < .05). Irrespective of footwear condition, perfusion to the hallux increased (3.97 ± 1.2 versus 6.9 ± 1.4 tissue perfusion units, P < .05) after exercise. Infrared images revealed no changes in foot temperature. Conclusions: The specialized cleat allowed participants to exercise with minimal forefoot stress. The observed increase in perfusion suggests that healing might improve if patients with active DFU were to use the cleat. Potential thermotherapy for DFU was not supported by this study. Evaluation of the device among individuals with active DFU is now warranted.

First Metatarsal

Diabetic foot ulcers under the first metatarsal head are difficult to treat and prevent recurrence. The aim of this study is to summarize the results of a distal first metatarsal minimally invasive floating osteotomy for ulcers under the first metatarsal head in patients with diabetic neuropathy. We reviewed files of patients with diabetic neuropathy undergoing a floating first metatarsal osteotomy. Demographic and clinical data were collected and analyzed to determine success and complications. We found records for 21 patients (mean age 64) with University of Texas 1A ulcers. The ulcer’s mean age was 11.2 months. Following surgery, the ulcer completely resolved after a mean of 3.7 (2 to 11) weeks in 19 patients. During the first year, there were 4 complications related to the surgery (including 3 infections). At latest follow-up, 17/21 (81%) patients had healed with satisfactory results. Minimal invasive floating distal osteotomy of the first metatarsal can cure and prevent recurrence of diabetic foot ulcers under the first metatarsal head in 80% of the patients, but the ability to provide close follow-up and prompt response are prerequisites.

Foot Model

With the development of societies, diabetic foot ulcers have become one of the most common diseases requiring lower extremity amputation. The early treatment and prevention of diabetic foot ulcers can considerably reduce the possibility of amputation. Using footwear to redistribute and relieve plantar pressure is one of the important measures for the treatment and prevention of diabetic foot ulcers. Thus, the evaluation and prediction of the distribution of plantar pressure play an important role in designing footwears. Herein, the finite element method was used to study plantar pressure under two kinds of foot models, namely, the skeletal structure foot model and the whole foot model, to explore the influence of human bones on the pressure of the soles of the feet and obtain accurate foot pressure. Simulation results showed that under the two models, the plantar pressure and the pressure from the footwear with ethylene vinyl acetate were all reduced. The total deformation demonstrated a slight increase. These stresses are very useful as they enable the design of suitable orthotic footwear that reduces the amount of stress in individuals with diabetic foot ulcers.

Foot Posture

Background: Fatigue due to running has been shown to contribute to changes in plantar pressure distribution. However, little is known about changes in foot posture after running. We sought to compare the Foot Posture Index before and after moderate exercise and to relate any changes to plantar pressure patterns. Methods: A baropodometric evaluation was made, using the FootScan platform (RSscan International, Olen, Belgium), of 30 men who were regular runners and their foot posture was examined using the Foot Posture Index before and after a 60-min continuous run at a moderate pace (3.3 m/sec). Results: Foot posture showed a tendency toward pronation after the 60-min run, gaining 2 points in the Foot Posture Index. The total support and medial heel contact areas increased, as did pressures under the second metatarsal head and medial heel. Conclusions: Continuous running at a moderate speed (3.3 m/sec) induced changes in heel strike related to enhanced pronation posture, indicative of greater stress on that zone after physical activity. This observation may help us understand the functioning of the foot, prevent injuries, and design effective plantar orthoses in sport. (J Am Podiatr Med Assoc 103(2): 121–125, 2013)
