Peripheral Nerve Disorders

Peripheral nerve disorders encompass a range of conditions—from carpal tunnel syndrome and ulnar neuropathy to thoracic outlet syndrome and pudendal neuralgia—in which compressed or damaged nerves produce pain, weakness, or sensory loss that can significantly impair daily function. Accurate diagnosis has traditionally relied on electrodiagnostic methods such as nerve conduction studies, which measure how efficiently electrical signals travel along a nerve, and neurophysiological grading scales that stratify disease severity to guide treatment decisions. Imaging techniques, particularly high-resolution ultrasound and MRI, have become increasingly important complements to these electrical tests, allowing clinicians to visualize the nerve's anatomy, detect structural changes like swelling or scarring, and locate entrapment sites that electrodiagnostics alone cannot pinpoint. An active area of investigation concerns how well imaging measurements correlate with electrodiagnostic findings across disease severity, and whether combined approaches can better predict which patients will respond to conservative management versus surgical intervention.
