Nerve repair surgery—whether nerve grafting, nerve transfer, or direct repair—offers hope for people with peripheral nerve injuries, including brachial plexus injuries. However, surgery is just the beginning of the recovery journey. After the surgeon has reconnected or rerouted nerves, there's a waiting period while regenerating nerve fibres grow toward their target muscles. This process is slow, measured in months rather than weeks.

During this waiting period, a critical question arises: what happens to the muscles? Without nerve signals, they begin to atrophy and deteriorate. If the muscle degenerates too severely before reinnervation occurs, even successful nerve regeneration may not restore function—the nerve reconnects, but finds a muscle no longer capable of responding.

This is where electrical stimulation plays a crucial role. By keeping muscles viable during the reinnervation window, stimulation can significantly improve the chances of functional recovery. In this article, I'll explain how nerve regeneration works, when to consider electrical stimulation, and what to expect throughout the process.

In this article, we step back and consider how brachial plexus injuries are treated and then look at how forms of electrical stimulation might contribute to achieving the best clinical outcome.

Brachial plexus injuries present a complex challenge in medical practice, with the potential to produce significant functional impairment and reduced quality of life. Effective treatment requires a meticulous, multifaceted approach, combining surgical and non-surgical interventions tailored to the patient's specific needs. This article explores current treatment strategies, focusing on the potential role of electrical stimulation as a complementary therapy. By examining its applications and efficacy, we aim to highlight how this innovative technique could enhance recovery and optimise clinical outcomes for individuals affected by these injuries.
