Nerve conduction studies uses small electric pulses to evaluate how electrical signals travel through the nerves. Small electrical impulses measure how well a nerve is functioning, localizing the problem and assessing its severity. NCS is commonly used to evaluate carpal tunnel syndrome, ulnar neuropathy, peripheral neuropathy, and plexopathy.

Electromyography evaluates the electrical activity of muscles at rest and during activation. A small needle electrode is used to help determine whether symptoms are arising from a pinched nerve, peripheral nerve injury, muscle disorder, plexopathy, or motor neuron condition. Findings are interpreted in the context of the clinical history, examination, imaging, and nerve conduction studies to provide clear localization and diagnosis.

Neuromuscular ultrasound provides real-time imaging of nerves, muscles, tendons, and surrounding soft tissues. When integrated with electrodiagnostic testing, ultrasound adds structural information that may not be apparent on EMG or nerve conduction studies alone. This combined approach can improve localization and diagnostic precision in conditions such as nerve entrapment, nerve injury, and muscle disorders.
