Nerve and muscle testing for children in Bangalore. Shishuka Children's Hospital offers NCS and EMG to diagnose weakness, numbness and neuromuscular conditions in a gentle, child-friendly setting.
A precise diagnostic test that measures how well your child's nerves and muscles are working — helping our pediatric neurologists identify the cause behind weakness, numbness or unusual muscle function.
A Nerve Conduction Study (NCS) measures how quickly and strongly electrical signals travel along a child's nerves, using small adhesive electrodes placed on the skin. Electromyography (EMG) measures the electrical activity produced by muscles, often using a very fine needle electrode, to see how well nerves are communicating with the muscles they control.
Together, these two tests help pediatric neurologists tell the difference between a problem originating in the nerves, the muscles, or the connection between them — information that's essential for accurately diagnosing conditions like muscular dystrophy, nerve injuries, or other neuromuscular disorders.
Your pediatric neurologist may recommend this test if your child is experiencing any of the following:
Muscle weakness that seems to be getting worse over time
Difficulty climbing stairs, running, or getting up from the floor
Numbness, tingling or pain that keeps returning in the arms or legs
Unusual muscle tone — persistently floppy or unusually stiff limbs from infancy
A suspected nerve injury, such as after trauma or a difficult birth
A family history of muscular dystrophy or other inherited neuromuscular conditions
Depending on your child's symptoms, one or both of these tests may be recommended.
A small electrical impulse is delivered through electrodes on the skin, and the speed and strength of the nerve's response is measured. This is the more commonly performed of the two tests and is well tolerated by most children.
A thin needle electrode is briefly inserted into specific muscles to record their electrical activity at rest and during gentle movement, giving direct insight into muscle and nerve function.
Often performed together in the same visit for the most complete picture, especially when the cause of weakness or numbness isn't clear from either test alone.
A variation of NCS that repeatedly stimulates a nerve to check for fatigue in the nerve-muscle connection, used when a condition affecting that junction is suspected.
Here's how nerve and muscle testing fits alongside other neurology investigations.
| Investigation | Invasiveness | Best For | Limitation |
|---|---|---|---|
| NCS | Minimally invasive | Assessing nerve signal speed & strength | Doesn't directly measure muscle activity |
| EMG | Minimally invasive | Direct muscle & nerve-muscle junction assessment | Brief discomfort from the needle electrode |
| Brain/Spinal MRI | Non-invasive | Structural causes in the brain or spinal cord | Doesn't assess nerve or muscle function directly |
| Genetic Testing | Non-invasive (blood test) | Confirming inherited neuromuscular conditions | Cannot show current nerve/muscle function |
A structured, gentle process, with each step explained to your child in an age-appropriate way beforehand.
Your neurologist reviews your child's symptoms and history, and explains which nerves or muscles will be tested and why, so there are no surprises on the day.
Small electrodes are placed on the skin over specific nerves, and brief, mild electrical pulses are delivered — usually felt as a quick tingling or tapping sensation rather than pain.
If EMG is also required, a very fine needle electrode is briefly placed into specific muscles to record activity. This step is usually brief and localized to a few key muscle groups.
Results are reviewed by your pediatric neurologist and discussed at a follow-up visit, often alongside other test findings, to build a complete picture of your child's condition.
A calm, thorough approach to a test that requires both precision and patience with young patients.
Tests performed and interpreted by specialists experienced in pediatric neuromuscular conditions.
Each step explained simply beforehand, so your child knows what to expect and feels less anxious.
Results connected with physiotherapy and other specialists when ongoing management is needed.
Findings explained in plain language, with a clear plan for what comes next.
Care available across Kalyan Nagar, RT Nagar, Malleswaram and New BEL Road.
There's no recovery time needed after an NCS, and your child can return to normal activities immediately. If an EMG was performed, there may be very mild, short-lived soreness at the needle sites, similar to a minor bruise, which typically resolves within a day or two.
Results are usually reviewed and discussed at a follow-up appointment, where your neurologist will explain what the findings mean and outline the next steps, whether that's further testing, a referral, or a treatment plan.
Our pediatric neurology team is here to guide you through every step, from your first consultation to a clear explanation of results.

The needle electrode causes brief, mild discomfort similar to a quick pinch, and most children tolerate it well, especially with preparation beforehand. The nerve conduction part (NCS) feels more like a light tap or tingle than pain.
An NCS alone usually takes 20–30 minutes. If EMG is also needed, the full visit can take 45–60 minutes, depending on how many nerves and muscles are being tested.
Sedation is rarely needed. Most children, including younger ones, tolerate the test well with reassurance and distraction. It's normal for a child to feel a bit uneasy about the needle part of EMG, but this passes quickly.
NCS and EMG show how the nerves and muscles are functioning, which helps narrow down the cause significantly. In many cases, additional tests like blood work, genetic testing or imaging are used alongside these results to reach a final diagnosis.
