Objective Measures of Nerve Integrity, Posture, Gait and Blood Flow, After Nerve Decompression (OMNIFICENT)
February 15, 2021 updated by: James Anderson, DPM, Foot Surgery Center of Northern Colorado
Objective Measures of Nerve Integrity, Posture, Gait and Blood Flow, After Nerve Decompression In diabetiC Neuropathy PatiENTs
The purpose of this study is to measure the effect of nerve decompression on the recovery of the treated nerves.
To obtain objective data during surgery of the treated nerves' via electrical signals and muscle power when stimulated.
Also, to monitor muscle strength, balance/gait and blood flow in the lower extremity before and after surgery.

Detailed Description
Nerve decompression (ND)as treatment for the foot complications of diabetic sensorimotor peripheral neuropathy (DSPN) is a controversial topic although many patients find it provides gratifying relief of pain and numbness.
Neural electrical monitoring has been used intra-operatively to diagnosis nerve abnormality, monitoring for ongoing normal nerve function and confirm nerve integrity for spine surgeries and thyroid surgeries with success.
Presently there is not objective data to indicate the the use of neural electrical monitoring is reliable or effective.
The goal of this study is to measure objectively and quantifiable clinical surgical outcomes of nerve decompression surgery in diabetic neuropathy patients.
The study is designed to measure changes in nerve function, gait, balance and blood flow in the lower limb.
