Electromyography (EMG)

Electromyography (EMG) is a diagnostic test used to evaluate the health of muscles and the nerves that control them. It records the electrical activity produced by skeletal muscles at rest and during contraction. EMG is commonly performed along with Nerve Conduction Studies (NCS) to accurately diagnose neuromuscular disorders.

Purpose of the EEG Test

• Identify muscle disorders (myopathies)
• Detect nerve damage or nerve compression
• Diagnose conditions affecting the motor neurons
• Differentiate between nerve and muscle diseases
• Evaluate unexplained muscle weakness, pain, or cramps
• Assess neuromuscular junction disorders
• Monitor disease progression or recovery

Preparation Before EEG Test

• Bathe or shower before the test
• Avoid lotions, oils, or creams on the skin
• Wear loose, comfortable clothing
