Advanced Neuro Care in India — Assuring Rhythm in Your Life
Rhythm Heart Institute is one of India’s leading multi-speciality hospital networks, with a dedicated Department of Neurology offering advanced electromyography (EMG) using the latest digital equipment across Vadodara, Bharuch, Bhavnagar, Dahod, and Banswara. An EMG is a safe, quick, radiation-free test that measures the electrical activity of the muscles and the nerves controlling them — helping our neurologists identify the exact cause of muscle weakness, pain, and fatigue.
Performed by experienced neurologists, the test gives precise information about how well your muscles and nerves are working together. It is one of the most reliable tools for diagnosing muscle and nerve disorders, and is often carried out alongside a nerve conduction study (NCS).
Electromyography (also called an EMG or muscle study) is a test that records the electrical signals produced by muscles when they are at rest and when they contract. A very thin needle electrode is gently placed into the muscle, where it picks up these signals and displays them as waveforms and sounds for the neurologist to analyse.
By studying this activity, the neurologist can tell whether muscle weakness is caused by a problem in the muscle itself, the nerve supplying it, or the connection between them. An EMG is usually combined with a nerve conduction study (NCS) — NCS checks the nerves, while EMG checks the muscles — giving a complete picture. The test uses no radiation.
Your neurologist may recommend an EMG to find the cause of muscle or nerve symptoms or to monitor a known condition. Common reasons include:
Muscle weakness or unexplained loss of strength
Muscle cramps, twitching, or wasting
Numbness, tingling, or pain in the arms or legs
Pinched nerves, herniated disc, or sciatica
Muscle disorders (myopathy) and inflammatory muscle disease
Motor neuron diseases such as ALS
Conditions affecting nerve-to-muscle signalling, such as myasthenia gravis
Needle EMG — the standard study that records electrical activity directly from the muscle.
Combined EMG & NCS — muscle and nerve testing together for a complete diagnosis.
Single-Fibre EMG — a highly sensitive study used to evaluate conditions like myasthenia gravis.
Repetitive Nerve Stimulation — assesses disorders of the nerve-to-muscle junction.
Quantitative EMG — detailed analysis for complex muscle and nerve disorders.
Do not apply oils, lotions, or creams on the skin on the day of the test.
Wear loose, comfortable clothing for easy access to the area being tested.
Inform your doctor if you take blood thinners or have a bleeding disorder.
Mention any pacemaker or implanted device, and continue usual medicines unless advised otherwise.
You sit or lie comfortably while the skin over the muscle is cleaned.
A very thin needle electrode is gently placed into the muscle.
You relax the muscle, then gently tighten it as instructed.
The electrical signals are recorded as patterns and sounds.
The steps are repeated for each muscle being studied.
The test usually takes 30 to 60 minutes, depending on how many muscles are examined. You may feel a brief pinch or mild ache as the needle is placed.
You can return to normal activity right away.
Mild soreness or a small bruise at the needle sites is normal and settles in a day or two.
The neurologist reviews the recordings and interprets the results.
Your findings are explained, and further tests or treatment are advised if needed.
| Test Type | Minimally invasive recording of muscle electrical activity |
| Radiation | None — records the muscles’ own electrical signals |
| Anaesthesia | Not required — you stay awake throughout |
| Sensation | A brief pinch or mild ache as the thin needle is placed |
| Duration | Approximately 30–60 minutes |
| Hospital Stay | Outpatient (OPD) — no admission required |
| Availability | Across Vadodara, Bharuch, Bhavnagar, Dahod & Banswara |
Yes — an EMG is a very safe and routinely performed test. It uses no radiation and the needle electrodes are extremely fine. Most people feel only a brief pinch or mild ache during the test. Any minor soreness or small bruising at the needle sites usually settles within a day or two.
Serious problems are very rare. If you take blood thinners, have a bleeding disorder, or have a pacemaker or implanted device, simply inform our team in advance so the test can be planned with extra care. Our experienced neurology team uses strict sterile techniques to ensure your safety and comfort.

Most people feel only a brief pinch or mild ache as the thin needle is placed into the muscle. Any discomfort is short-lived and well tolerated, and there is no lasting pain.
An EMG checks the electrical activity of the muscles using a fine needle, while an NCS measures how well the nerves carry signals using surface electrodes. They are often performed together for a complete diagnosis.
Avoid applying oils, lotions, or creams on the skin, wear loose clothing, and continue your usual medicines unless told otherwise. Inform the team if you take blood thinners, have a bleeding disorder, or have a pacemaker.
Side effects are minimal. You may notice mild soreness or a small bruise at the needle sites, which usually settles within a day or two. You can resume normal activities immediately.
No. An EMG uses no radiation. It simply records the natural electrical signals produced by your muscles.
Your neurologist reviews the recordings and usually shares the report shortly after the test, along with any recommended next steps.
