Vestibular Testing (VNG)

VNG (Video Nystagmography) is used to determine if inner ear functions are the cause of dizziness and balance disorders. VNG is a series of tests that examine the involuntary movement of the eyes known as nystagmus. The movements are recorded through infrared cameras in the form of goggles placed over the eyes. The only discomfort from this comprehensive exam comes as a result of wearing goggles. VNG is one of the only tests that can determine if the problem is unilateral (one ear) or bilateral (both ears).

Autonomic Nervous System Testing (ANSAR)

ANSAR testing is a painless, non-invasive diagnostic procedure that determines how well a patient’s autonomic nervous system is functioning. The autonomic nervous system is the involuntary part of everyone’s neurological make-up and manages just about every system in the body. It controls digestion, sleep, breathing, circulation, blood pressure, heart rate, and even stress. There are two breathing challenges during Ansar testing which measure the balance between the sympathetic and parasympathetic branches of the autonomic nervous system.

Nerve Conduction Testing (NCV)

A nerve conduction velocity (NCV) test determines how quickly electrical signals move through a particular peripheral nerve. This test is useful for diagnosing a variety of different muscular and neuromuscular disorders. A doctor may use this test if they suspect a pinched nerve. Alternately, they may use it if they wish to check for the presence of a nerve disease.

Electromyography (EMG)

An EMG is a recording of the electrical activity in the muscles. It is performed to discover the cause of: Muscle Weakness, Muscle Spasms, Paralysis, Pain in the Arms, Hands, and Legs. 

Somatosensory Evoked Potential (SSEP)

SSEP is a test showing the electrical signals of sensation going from the body to the brain. The signals show whether the nerves that connect to the spinal cord are able to send and receive sensory information like pain, temperature, and touch. When ordering electrical tests to diagnose spine problems, SSEP is combined with an electromyogram (EMG), a test of how well the nerve roots leaving the spine are working.

Musculoskeletal ultrasound (MSKUS)

Musculoskeletal ultrasound is a study which helps diagnose and guide the treatment of a variety of soft tissue disorders, peripheral nerve injuries and inflammatory disorders. MSKUS is dynamic, safe, and has few technical limitations with no contraindications.


Sudoscan is a critical tool in the area of preventative medicine. For diabetic and symptomatic patients, regular autonomic neuropathy screening and follow up is now mandated. Just from a physical exam you cannot diagnose the possibility of diabetic neuropathy. Finding other methods of diagnosis is important to prevent complications in patients with neuropathy, which can lead to ulceration, loss of limbs, and so on. In addition to a physical exam diagnostic testing is recommended to detect diabetic neuropathy.
