May support duplex Doppler as alternative to plethysmography for static forearm flow; leaves open prospective validation.
Does duplex Doppler ultrasound provide comparable blood flow measurements to occlusion plethysmography in the forearm during static exercise?
Duplex Doppler ultrasound and occlusion plethysmography provide comparable measurements of forearm blood flow during static exercise, though plethysmography cuff pressure may decrease brachial artery flow.
