The Neuropathic element of the assessment is to determine the effectiveness of the sensory receptors, and their ability to transmit sensations to the brain. Light-touch, sharp-touch, vibration, warm-cold sensations are all used to test the various receptors found in the body. Also muscle tone is tested to assess the effectiveness of the motor neurons that instruct the muscles to move.
The vascular assessment checks on the blood pressure and circulation associated with the lower limb producing what is known as an ankle/brachial index. This determines any arterial problems that may be a cause for concern.
The combined assessments can pick-up early stages of any impairment that may be developing in the body. Including heart disease and diabetes.
