Neurophysiology Care at CritiCare Asia, Juhu
An MRI shows what a nerve looks like. It doesn't show whether that nerve is actually working. That's the gap neurophysiology fills - it studies the nervous system electrically, not structurally, tracing how signals move through the brain, spinal cord, nerves, and muscles in real time. Take a nerve running along the inner forearm. On a scan, it can look completely normal. But if the electrical signal slows by even a few milliseconds crossing the elbow, that's a sign of compression an image alone would never catch. Neurophysiology doesn't take a picture. It records activity - live, and sometimes changing within seconds. CritiCare Asia Hospitals offers comprehensive care for neurophysiology in Juhu, Mumbai.
Why These Tests Are Needed
Many patients arrive with symptoms that don't show up on the outside. Tingling fingertips. Numbness down the outer leg. Brief blackouts nobody can explain. Muscle weakness with no obvious cause.
Neurophysiology helps answer the questions imaging can't:
- Is the problem in the nerve, the muscle, or the brain itself?
- Is it mild irritation, or actual nerve damage?
- Localised - say, at the wrist - or more widespread?
For patients who've been told their scans look fine but their symptoms persist, these neurodiagnostic tests in Mumbai often bring the first concrete answer. Sometimes that's the most reassuring part of the process.
Conditions Neurophysiology Helps Diagnose
Our Department of Neurology uses these tests across a wide symptom range:
- Peripheral nerve disorders
diabetic neuropathy, carpal tunnel syndrome, ulnar neuropathy at the elbow - Muscle disorders (myopathies)
weakness in the shoulders or thighs, difficulty rising from a seated position - Neuromuscular junction disorders
including Myasthenia Gravis, where nerve-to-muscle signalling becomes unreliable - Brain-related conditions
epilepsy, unexplained fainting, sleep disturbances - Spinal cord involvement
sensory changes travelling along an arm or leg, weakness linked to nerve root compression

Types of Neurophysiology Tests
More than one test is often needed, depending on the pattern of symptoms.
- Electroencephalogram (EEG)
records the brain's electrical activity through small electrodes placed on the scalp. It typically takes 45 to 60 minutes and is used to evaluate seizures, unexplained fainting, and sleep disorders. When events are infrequent, video EEG monitoring over a longer stretch can capture what a single session might miss. - Nerve Conduction Study (NCS)
stimulates a nerve — at the wrist or ankle, most commonly — with a mild electrical impulse, then measures the response further along the same nerve. Patients often expect a shock. It's closer to a brief tap. The test measures conduction speed, signal strength, and pinpoints where along the nerve a problem sits. - Electromyography (EMG)
goes a step further, assessing the muscle directly. A fine needle, thinner than a standard injection needle, records electrical activity first at rest, then during controlled movement. Comparing the two patterns helps separate a nerve problem from a muscle one.
What to Expect
- Before the test
No fasting required - eat normally. Skip oils or lotions on the arms and legs that day, and wear loose clothing that allows easy access to the forearms, calves, or thighs. Let the team know if you're on blood thinners or have a pacemaker; for select tests, such as those used in Myasthenia Gravis workups, certain medications may need to be paused, but only under medical guidance. - During the test
You'll be awake throughout, and most sessions are outpatient. EEG involves lying still while electrodes are placed on the scalp - you may be asked to breathe deeply or look at a flashing light. NCS causes a brief twitch, similar to the thumb jumping when the median nerve is stimulated at the wrist. EMG brings a short pricking sensation as the needle enters the muscle, a few millimetres deep at most. Depending on how many tests are required, the full session runs anywhere from 30 to 90 minutes. - After the test
There's no recovery period to speak of. Most patients resume their day immediately. Results are interpreted by the neurology team and shared with the referring doctor to shape the next step in diagnosis or treatment.
Neurophysiology Test Results
Neurophysiology results aren't a simple pass or fail. Your neurologist reads them alongside your symptoms, history, and any imaging already done, since the same electrical pattern can point to different causes in different patients. Reports typically take a few days to compile and review. Once ready, findings are discussed with you directly - what they show, what they rule out, and how they shape the treatment plan going forward. Consult our experienced neurophysiologists in Juhu, Mumbai at CritiCare Asia Hospitals to understand the test results.
Neurophysiology Care at CritiCare Asia Hospitals, Juhu
Neurophysiology here isn't run as a standalone lab - it's built into how our neurology team investigates and manages complex cases. Tests are ordered with a specific clinical question in mind, not as a routine add-on, and results feed directly into the treatment plan your neurologist builds. If symptoms like numbness, weakness, or unexplained episodes haven't been fully explained by imaging alone, a neurophysiology assessment may be the missing piece. Book a consultation with our neurophysiology specialists in Juhu at CritiCare Asia Hospitals, Juhu, to find out which test is right for you.
