Preventing Foot Injuries In Diabetic Athletes

Patient education is important in managing the diabetic athlete. Your educational efforts should consider the patient’s athletic activity and his or her diabetic foot status.

Key Pointers On Evaluating The Footwear Of Diabetic Athletes
It’s also important to evaluate the diabetic patient’s athletic gear.
Obviously, size is not the only consideration for proper shoe fit as a specific size shoe can come in many different last patterns. One should measure the foot with a dependable measuring device. Shoes should fit properly while the patient is weightbearing. The widest part of the shoe should accommodate the metatarsophalangeal joints. There should be three-eighths to one-half of an inch between the longest toe and the tip of the toe box, and adequate space around the heel. The athletic footwear should also have adequate “breathability” in order to avoid the buildup of thermal energy within the soft tissues of the foot, which can lead to tissue damage.
When they are used properly and have a proper fit, running shoes have been shown to be a valuable aid in reducing plantar foot pressure. In one study, running shoes reduced the tendency for plantar foot callus and decreased forefoot pressure by 30 percent, with pressure reduction of 44 percent under the second metatarsal head.
Since foot orthoses and inserts comprise common treatment modalities for sports related problems, you need to evaluate these as well for appropriateness and condition. About 90 percent of runners continue to use their orthotics after their condition has improved, with an average duration of 23 months. An orthotic device that may have been helpful at one point may be inappropriate or even detrimental two or three years later, and thus must be discontinued or changed.

Final Notes
Patient education is the most important part of managing the diabetic athlete. The education should be designed to meet the needs of each patient, considering his or her athletic activity and diabetic foot status. Obviously, a strategy of prevention is preferable to treatment in terms of cost to the patient and discomfort. The injured athlete should complete a program of rehabilitation in order to successfully return to full activity and continue his or her exercise regimen. If the athlete has healed from a foot ulcer, the goal is to prevent re-ulceration.
Preventing injuries involves proper selection of clothing, shoes and the surface to be trained on, as well as good training techniques and proper preparation. Knowledge of the causes of foot infection, ulcerations and injuries by the athlete is an essential part of the prevention process.
