Design of a Device to Ease and Improve the Diagnosis of Popliteal Artery Entrapment Syndrome

Popliteal artery entrapment syndrome (PAES) is a condition affecting blood flow in the back of the leg, which can have a significant impact on the patient's life. It is often misdiagnosed due to a lack of standardized procedures and quantifiable diagnostic criteria. To facilitate easier and more accurate diagnosis of this syndrome, we have designed and built an initial prototype of a device that provides adjustable resistance during plantar-flexion of the patient's ankle while quantifying force generated and ankle range of motion. The device will be used while the physician observes blood flow through the popliteal artery in the back of the knee using an ultrasound. The device provides a convenient and ergonomic solution for patients and physicians, which helps improve the accuracy of PAES diagnosis and allows physicians to further study this condition.
