How We Diagnose Peripheral Neuropathy
Evaluating Your Peripheral Neuropathy
While some patients may have already received a diagnosis of peripheral neuropathy from their physician, our center is equipped to perform a range of sensory, motor, and circulatory tests to determine the causes of your peripheral symptoms and assess your ability to heal.
Physical Examination and Assessment
A physical examination and a number of assessment tools will help our medical team evaluate the physical symptoms of your neuropathy, the impact of these symptoms on your quality of life and recommend a personalized treatment plan.
Pulse Volume Recording (PVR)
Quantitative Sudomotor Axon Reflex Test (QSART)
Skin Perfusion Pressure (SPP)
Ankle Brachial Index (ABI), Toe Brachial Index (TBI), and Digital Brachial Index (DBI)
The Ankle Brachial Index (ABI) measures the ratio of the blood pressure at the ankle, and the Toe Brachial Index (TBI) measures the blood pressure of the big toe. These measurements are then compared to the blood pressure in the upper arm (brachial artery) to assess the blood flow from the legs to the feet and toes. For those experiencing neuropathy in their hands, a Digital Brachial Index (DBI) measures the blood pressure in the fingers, comparing it to the pressure in the brachial artery to assess the blood flow in the arms. The ABI, TBI, and DBI can help determine whether you have peripheral arterial disease (hardening or calcifications of the arteries).
