This test is done by measuring blood pressure at the ankle and in the arm while a person is at rest. Measurements are then repeated at both sites after 5 minutes of walking on a treadmill.
By dividing the highest blood pressure at the ankle by the highest recorded pressure in either arm, the ankle-brachial index (ABI) can be calculated. The ABI result is used to predict the severity of peripheral arterial disease (PAD) that may be present. A decrease in the ABI result with exercise is a sensitive indicator that significant PAD is probably present.

The analysis of dynamic or static pressure distribution revolves around Tekscan's innovative, real-time, tactile sensing systems. These systems are capable of measuring critical patient/surface interfaces with minimal interference. Extremely thin, flexible sensors accommodate most contours and provide highly accurate local pressure readings. Tekscan's pressure sensors provide the most appropriate spatial resolution required for the medical application under consideration. Vivid graphics, displayed on a PC, make the information easy to interpret and provide the clinician with excellent documentation.

The underlying pathophysiology of this test is relatively easy to understand. When blood flow into the foot is ceased, vasodilatory metabolites accumulate and cause relaxation of smooth muscle in the arterioles, venules and the pre-capilllary sphincters. Resistence in these vessels then decreases. Because blood flow is proportional to pressue/resistence, blood flow to the foot should increase proportionately. When there is significant organic occlusion in the foot or proximal to it, even though the resistence in the foot is decreased, the volume of blood that can flow past the obstruction per unit time is limited. In lay terms, it takes longer for the blood to reach the foot when compared with normal rates. With this in mind it is possible for the clinician to make a qualitive evaluation of the foot noting uniformity and level of erythema as well as time of colour return

The NCV test can be used to detect true nerve disorders (such as neuropathy) or conditions whereby muscles are affected by nerve injury (such as carpal tunnel syndrome). Normal body temperature must be maintained for the NCV test, because low body temperatures slow nerve conduction

Current  Perception  Threshold  Test is a sensory test, which differentiates and quantifies your pain. The test is painless but time consuming. The test helps to diagnose cause of your pain and it helps to monitor the effects of your treatment.

The Neurometer utilizes three neuro-selective electrical stimuli to perform extremely sensitive quantitative assessment sensory nerve fibers at any cutaneous site.

The  current  perception threshold (CPT) value is the minimum amount of a current trans- cuatneously applied neuroselective current that a person consistently perceives as evoking a sensation.

CPT values are obtained for large diameter myelinated, small diameter myelinated and unmyelinated sensory nerve fibers by stimulating with three different neuroselectvie sine wave stimuli at 200Hz, 250Hz, and 5Hz, respectively. (Hz =3D cycle per second)
