A recent study found that prefabricated insoles perform comparably to custom-made insoles in reducing peak plantar pressure and ulceration risks in patients with neuropathic complications resulting from diabetes.
One hundred nineteen participants with diabetic neuropathy were randomly assigned to wear either a custom-made insole or pre-fabricated insole. Using the F-scan in-shoe pressure management system, peak pressure, forefoot pressure time integral, total contact area, forefoot rate of load and duration of load as a percentage of stance were measured when the insole was given to participants and then again after 6 months. The researchers also measured perceived foot health, quality of life and cost of supply and fitting.
The researchers found no differences between insoles in reducing peak pressure. The only kinematic difference was that custom insoles were slightly more effective in reducing forefoot pressure time integral.
“The custom-made insoles are more expensive than prefabricated insoles evaluated in this trial and no better in reducing peak pressure,” the authors wrote in the study. “We recommend that where clinically appropriate, the more cost effective prefabricated insole should be considered for use by patients with diabetes and neuropathy.”
