The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. [1] It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema, in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.

This constitutes a positive Thomas test. [2] Sometimes, with a very flexible patient, the Thomas test will be normal despite a psoas dysfunction being present. However, in the patient with a normal hip joint, a positive test is a good indicator of psoas hypertonicity. [2] Other signs from the Thomas test:
Distraction tests: positive tests are rechecked when the patient's attention is distracted, such as a straight leg raise test; Regional disturbances: regional weakness or sensory changes which deviate from accepted neuroanatomy; Overreaction: subjective signs regarding the patient's demeanor and reaction to testing
The modified Allen's test is also performed prior to heart bypass surgery. The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit.
