Understanding Nerve and Muscle Function Through Objective Testing
Electrodiagnostic testing evaluates the physiological function of peripheral nerves and muscles. These studies can help identify the presence, location, severity, and physiological characteristics of neuromuscular abnormalities.
Nerve Conduction Studies (NCS)
Nerve conduction studies assess how effectively electrical signals travel through peripheral nerves. These studies help evaluate conditions such as:
- Carpal tunnel syndrome
- Cubital tunnel syndrome (ulnar neuropathy)
- Other peripheral nerve entrapments
- Peripheral polyneuropathy
- Focal nerve injuries
- Selected demyelinating and axonal neuropathies
NCS findings can help determine whether peripheral nerve dysfunction is present and characterize its severity and physiological features.
Needle Electromyography (EMG)
Needle EMG evaluates the electrical activity of skeletal muscles at rest and during voluntary contraction. It provides information regarding muscle membrane stability and motor unit function, and can help identify abnormalities associated with:
- Cervical and lumbosacral radiculopathy
- Peripheral nerve injuries
- Immune-mediated motor nerve fiber diseases
- Selected neuromuscular disorders
- Myopathic conditions
- Disorders affecting motor neurons
When clinically indicated, NCS and needle EMG are performed together for a more comprehensive assessment.
Neuromuscular Ultrasound
Neuromuscular ultrasound may be available upon request as an adjunct to electrodiagnostic testing. Ultrasound provides structural information about peripheral nerves and surrounding tissues, complementing the physiological and pathological information obtained through EMG/NCS.
Conditions We Commonly Evaluate
Electrodiagnostic Testing for Peripheral Nerve and Muscle Disorders
EMG/NCS may be clinically appropriate for patients presenting with symptoms or suspected conditions involving:
Upper Extremities
- Carpal tunnel syndrome
- Ulnar neuropathy at the elbow or wrist
- Radial neuropathy
- Brachial plexopathy
- Cervical radiculopathy
- Other focal upper-extremity neuropathies
Lower Extremities
- Lumbosacral radiculopathy
- Fibular (peroneal) neuropathy
- Tarsal tunnel syndrome
- Sciatic neuropathy
- Other focal lower-extremity neuropathies
Generalized Neuromuscular
- Peripheral polyneuropathy
- Selected acquired demyelinating neuropathies
- Motor neuron disorders
- Selected myopathic disorders
- Other disorders affecting peripheral nerve or motor unit function
The selection and extent of testing are determined by the patient's clinical presentation, examination findings, and diagnostic needs.
