We bring all the neurological testing under one roof. The tests are performed by trained technician on worldclass testing devices. Accurate and reliable test results are delivered in a quick and speedy way. 

An Electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. An EMG is done to find diseases that damage muscle tissue, nerves, or the junctions between nerve and muscle. These problems may include a PIVD (Prolapsed Intervertebral disc), Amyotrophic lateral sclerosis (ALS), Motor Neuron Disease (MND), Myopathy or Myasthenia gravis (MG).

EMG - Electromyogram
NCS - Nerve conduction study

Nerve Conduction Study (NCS) is done to find the damage to the peripheral nervous system. NCS’s are used mainly for evaluation of paresthesias (numbness, tingling, burning) and/or weakness of the arms and legs.

The nerve conduction study consists of the following components-

  • Motor NCS

  • Sensory NCS

  • F wave study

  • H-reflex study

Motor NCS are performed by electrical stimulation of a peripheral nerve and recording from a muscle supplied by this nerve.

Motor NCS
Sensory NCS
H-reflex study
F-wave study

F-wave study uses supramaximal stimulation of a motor nerve and recording of action potentials from a muscle supplied by the nerve.

H-reflex study uses stimulation of a nerve and recording the reflex electrical discharge from a muscle in the limb<.p>

Some of the common disorders that can be diagnosed by nerve conduction studies are:

  • Peripheral neuropathy

  • Carpal tunnel syndrome (CTS)

  • Ulnar neuropathy

  • Guillain-Barré syndrome (GBS)

  • Spinal disc prolapse

  • Cubital Tunnel Syndrome

  • Tarsal Tunnel Syndrome

  • Peroneal neuropathy

  • Alcoholic neuropathy

  • Diabetic neuropathy

  • Nerve effects of uremia (from kidney failure)

  • Traumatic injury to a nerve

  • Brachial plexopathy

  • Mononeuritis multiplex

  • Radial nerve dysfunction (Wrist drop)

  • Sciatic nerve dysfunction

  • Ulnar nerve dysfunction

Sensory NCS are performed by electrical stimulation of a peripheral nerve and recording from a purely-sensory portion of the nerve, such as on a finger.

EEG - Electroencephalogram

The Electroencephalogram (EEG) is a measure of brain waves. EEG is used in the evaluation of brain disorders. Most commonly it is used to show the type and location of the activity in the brain during a Seizure. It also is used to evaluate people who are having problems associated with brain function. These problems might include confusion, coma, tumors, long-term difficulties with thinking or memory, or weakening of specific parts of the body (such as weakness associated with a stroke). An EEG is also used to determine brain death. It may be used to prove that someone on life-support equipment has no chance of recovery.

BAER - Brainstem auditory evoked response

The BAER assists in evaluating the auditory nerve pathways from the ears through the brainstem. Electrodes are attached to the scalp and earlobes and earphones are placed over the ears. The earphones deliver a series of clicks or tones to each ear separately. The most common uses of the BAER are in Multiple Sclerosis (MS) and in Cerebellopontine angle lesions (acoustic neuromas.)

Video EEG

VEEG records seizures on videotape and on computer so that the doctor can see what happens just before, during, and right after a seizure. This test can be very helpful in finding the specific area of the brain that the seizures may be coming from. It is also helpful in diagnosing Psychogenic seizures (Non-Epileptiform attacks/Pseudo-Seizers), which may look like real seizures but do not affect the electrical activity in the brain. Video EEG may be used short-term or long-term:

  • Short-term monitoring is done on an outpatient basis and may last up to 4 hours.

  • Long-term monitoring is done in the hospital and may last 3 to 7 days.

VEP - Visual evoked potential

The VEP evaluates the visual nervous system from the eyes to the occipital (visual) cortex of the brain. Electrodes are applied to the scalp. Patients are usually asked to stare at a pattern on a video screen while remaining fully alert. Each eye is tested separately.

With an abnormal VEP, the differential diagnostic considerations include the following:

  • Optic neuropathy

  • Optic neuritis (To diagnose and monitor Multiple Sclerosis)

  • To evaluate signs and symptoms of visual loss in persons who are unable to communicate (e.g., unresponsive persons, Infants)

  • Ocular hypertension

  • Glaucoma

  • Diabetes

  • Toxic amblyopia

  • Leber hereditary optic neuropathy

  • Aluminum neurotoxicity

  • Manganese intoxication

  • Retrobulbar neuritis

  • Ischemic optic neuropathy

  • Tumors compressing the optic nerve – Optic nerve gliomas, meningiomas, craniopharyngiomas, giant aneurysms, and pituitary tumors
