Nerve Conduction Study (NCS) and Electromyogram (EMG):

With both being sufficient diagnostic procedures, the main purpose is to accurately identify the nerve injury or muscle disease. Nerve Conduction Studies (NCS) measure the electrical activities of the peripheral nervous system. Electrodes are attached and impulses are conducted using an instrument. Electromyography (EMG) measures the electrical activity of muscles. It is performed by utilizing a needle in several muscular sites.

Both tests assist in identifying diseases such as:

• Peripheral nerve problems such as Carpal tunnel syndrome (CTS)
• Nerve problems in the spine, such as herniated discs
• Muscle disease
• Amyotrophic lateral sclerosis (ALS)
• Neuromuscular junction disorders such as myasthenia gravis
