Effects of Mecobalamin on the Functional Outcomes of Complex Regional Pain Syndrome Type 1 of the Foot and Ankle.

This small study revealed an improvement of the functional outcomes in patients with CRPS type 1 of the foot and ankle who received mecobalamin instead of a placebo at 3 months that was not sustained at 6 and 12 months. We identified an average 39% total reduction in the amount of total pregabalin used in the mecobalamin group in the first 12 months.
