Efficacy of a hands-free vascular ultrasound probe holder in active and inactive limbs during cycling exercise

This study explores an ultrasound probe holder (PFD) for measuring blood flow during exercise, addressing the limitations of traditional methods. We compared PFD imaging with manual scanning in capturing artery diameter and blood velocity during cycling exercise. Results showed that the PFD matched trained sonographer accuracy at rest and outperformed them in capturing blood velocity during exercise in the inactive limb but not active limb. We highlight the PFD's potential impact in vascular physiology research.
