Quick Answer
NCS/EMG measures nerve and muscle function. It helps distinguish neuropathy patterns, entrapment syndromes, and muscle disease.

Nerve conduction studies (NCS) and electromyography (EMG) are tests that evaluate how well your nerves and muscles are working. NCS measures the speed and strength of electrical signals travelling along a nerve, while EMG records the electrical activity of muscles at rest and during contraction. Together, they help your neurologist determine whether symptoms like tingling, numbness, or weakness are caused by nerve damage, nerve compression, or a muscle disorder.
NCS is particularly helpful for distinguishing between different patterns of neuropathy —— for example, whether the problem is in the nerve fibres themselves (axonal neuropathy) or in the protective coating around nerves (demyelinating neuropathy). It also identifies entrapment syndromes such as carpal tunnel syndrome, where a specific nerve is compressed at a known anatomical site.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for peripheral neuropathy.
Preparation is straightforward: avoid applying lotions or oils to the skin on the day of testing, as these can interfere with electrode contact. Wear loose clothing that allows easy access to the arms and legs. The test uses small electrical pulses to stimulate nerves —— these may feel uncomfortable but are generally well-tolerated. The entire procedure typically takes 30 to 60 minutes.
Results are interpreted in the context of your clinical history. Abnormal nerve conduction does not always mean you need treatment —— mild changes may reflect age-related change or subclinical findings. Dr. Jitendra Prasad Yadav reviews NCS/EMG results alongside examination findings to guide management decisions at Kathmandu Neurology Clinic (Durbar Marg, Opposite of Yak & Yeti Hotel).

Not every case of tingling or numbness requires nerve conduction studies. Clinical examination and history often guide whether the test will change management. A judicious approach avoids unnecessary testing while ensuring that ambiguous or concerning presentations receive appropriate investigation.

Frequently asked questions
Answers reviewed by Dr. Jitendra Prasad Yadav • MBBS, MD (Internal Medicine), FICN (Neurology), FCNV, FIHM • NMC 8029
Supplements only help when a deficiency is present; underlying cause-directed care is needed.
If the underlying cause is corrected early (e.g., improving glucose control, treating vitamin deficiency), improvement may occur. Long-standing neuropathy is often not fully reversible.
Cervical sensations can coexist, but dizziness is often multifactorial and needs systematic assessment rather than assuming a single neck cause.
Yes; vertigo is the sensation of spinning. Dizziness is a broader term including lightheadedness, unsteadiness, and near-fainting. Different causes underlie each.
Progressive tingling starting in both feet, especially with diabetes, B12 deficiency or chemotherapy history, suggests peripheral neuropathy. Dr. Jitendra evaluates distribution (glove-stocking), underlying cause labs, and NCS/EMG when indicated. Burnout or anxiety alone rarely causes persistent stocking numbness — tar…
