%X Functional popliteal artery entrapment syndrome (fPAES), a cause of exertional leg pain, has a clinical presentation and clinical findings that are often indistinguishable from those of other leg pain causes (1). This condition may also coexist and overlap in symptomatology with other leg pain causes, further complicating the diagnosis (2). Although fPAES is usually considered a rare cause of leg pain (3), the true incidence of this condition is unknown, and fPAES is likely underdiagnosed and underreported (4). A missed diagnosis may result in disease progression and the use of unnecessary invasive procedures (3), and untreated fPAES may lead to popliteal artery damage, embolization, and limb ischemia (5). Although a diagnostic method using a combination of dynamic ultrasound and MR imaging/MR angiography has been described for fPAES (5), to our knowledge, no investigational studies have been performed to assess the dynamic ultrasound findings in this entity. This study sought to evaluate the usefulness of dynamic plantar flexion and dorsiflexion of the calf and the effect on the popliteal artery Doppler waveform in patients with clinically suspected fPAES and no structural abnormality
