These tests not only confirm the presence of a lesion but also help to differentiate between a pre-ganglionic injury (near the spine) and a post-ganglionic injury (distal to the nerve root). This reorganization is critical as it dictates the specific motor and sensory distribution.

Common Injuries and Pathologies Brachial plexus injuries are often the result of trauma, including motor vehicle accidents, contact sports, and childbirth. Acute trauma may necessitate immediate surgical exploration and repair, while chronic cases often focus on maximizing function through non-surgical means.
Diagnostic Approaches Modern diagnostics rely heavily on electrodiagnostic studies, such as electromyography (EMG) and nerve conduction studies (NCS). When this system functions optimally, we experience seamless movement and sensation; when compromised, the resulting deficits can be profound and life-altering.
