AI Article Synopsis
- Noninvasive methods to measure blood flow in muscles are not very advanced, but diffuse correlation spectroscopy (DCS) is a new technique showing promise in this area.
- A validation study compared DCS with Doppler ultrasound by measuring muscle blood flow during exercise in nine male subjects.
- The results indicated that DCS and Doppler ultrasound measurements were very closely correlated, and DCS proved to be more reliable, particularly in terms of reducing errors caused by movement.
Article Abstract
Noninvasive, direct measurement of local muscle blood flow in humans remains limited. Diffuse correlation spectroscopy (DCS) is an emerging technique to measure regional blood flow at the microvascular level. In order to better understand the strengths and limitations of this novel technique, we performed a validation study by comparing muscle blood flow changes measured with DCS and Doppler ultrasound during exercise. Nine subjects were measured (all males, 27.4 ± 2.9 years of age) for a rhythmic handgrip exercise at 20% and 50% of individual maximum voluntary contraction (MVC), followed by a post-exercise recovery. The results from DCS and Doppler ultrasound were highly correlated ( = 0.99 ± 0.02). DCS was more reliable and less susceptible to motion artifact.
