Exercise Training for Brachial Plexus Injury Following Nerve Transfer

Plain-language summary

Although peripheral nerve is capable of regrowth following injury, at only 1 mm/day, the slow rate represents a major barrier. Apart from rapid deterioration of the environment supportive of growth, denervated muscles become atrophic and bones osteoporotic. To successfully restore function, in addition to speeding up the nerve regeneration rate, treatments that can also restore muscle and bone mass are essential. Recently, in animal studies, the investigators showed that in addition to accelerating the speed of nerve regeneration, exercise training can also be used to restore muscle bulk and bone density. While promising, given the inter-species differences, the clinical utilities of this treatment need to be directly tested in humans. This will be done using a randomized controlled study design on patients with brachial plexus injury.
