It is used to screen for reduced blood flow in the legs, most often from peripheral artery disease (PAD). Clinicians use it in vascular, primary care, sports medicine, and orthopedic settings when circulation may affect symptoms or healing. It helps separate blood-flow problems from joint, muscle, nerve, or tendon causes of leg pain."}
