Botulinum Toxin Effects on Plantar Ulcer Recurrence
Completed · Not applicable · Has a placebo group
Conditions studied: Diabetes Mellitus, Peripheral Neuropathy, Plantar Ulcers
In brief
The purpose of this grant is to collect pilot data to assess the amount of botulinum toxin that needs to be injected into the calf muscles of subjects with diabetes mellitus, peripheral neuropathy, and a plantar ulcer to decrease muscle strength. We hypothesize that a decrease in plantar flexor muscle strength will temporarily decrease plantar pressure. The decrease in plantar pressure will provide temporary protection to the new tissue as it gains tolerance to high stress with the long term potential outcome as a decrease in the ulcer recurrence rate.
