Testing and Diagnosis at the Scottsdale Neuropathy Institute

We feel the most important part of the patient visit is the history and physical exam. This time allows us to become familiar with the patient and their problems. No diagnostic modality can compare to a thorough history and physical examination. In order to thoroughly diagnose and treat each patient we employ state of the art neurodiagnostic equipment.

The Pressure Specified Sensory Device (PSSD)

The Pressure Specified Sensory Device (PSSD) is the most accurate way of testing the lower extremity for sensory deficits. The PSSD is one of the best sensory measuring devices available that can quantify and record both specific peripheral nerve threshold levels and peripheral never innervation density (which reflects axonal degeneration). The PSSD is able to quantify pathologic changes at subclinical levels and is pain free.


Nerve Conduction Velocity Equipment

We also use nerve conduction velocity equipment, which is particularly useful in differentiating between lower back pathology, radiculopathy and distal motor/sensory neuropathies.

This device has a specificity of 90% and sensitivity of 86%. It is well tolerated by patients and is comparable to the traditional NCV/EMG testing.


Get Your MRI at SNI


As is fitting with the cutting edge nature of Scottsdale Neuropathy Institute, the practice now has an on-site MRI. The Magnetic Resonance Image scanner is made for extremities, and allows patients the convenience of having scans right at the office.

The MRI machine is called the O-Scan, and represents the latest in compact, powerful imaging technology.

Up until now, having this modern technology with such a small footprint has not been possible. Patients do not need to be put in a tube, eliminating any issues with claustrophobia.

The images produced are first rate, and immediately are able to be viewed by the Award Winning podiatrists. Why go to an outside imaging center when you can simply walk down the hall into a beautiful MRI suite?

Along with the stem cell injections, gait analysis machine, ultrasound therapy machine, Class 4 Lasers and nerve conduction study machine, Valley Foot Surgeons offers the latest in modern foot and ankle diagnosis and treatment.
