Comparison of laser speckle contrast imaging and laser-Doppler fluxmetry in boys and men

We compare microvascular reactivity assessed by laser-Doppler fluxmetry (LDF) and laser speckle contrast imaging (LSCI) of boys and men during rest, post-occlusive reactive hyperaemia (PORH), and cycling exercise. 19 boys (9 ± 1 y) and 18 men (22 ± 2 y) participated. LDF and LSCI measures were taken...

Description
Summary:We compare microvascular reactivity assessed by laser-Doppler fluxmetry (LDF) and laser speckle contrast imaging (LSCI) of boys and men during rest, post-occlusive reactive hyperaemia (PORH), and cycling exercise. 19 boys (9 ± 1 y) and 18 men (22 ± 2 y) participated. LDF and LSCI measures were taken of the forearm during rest, PORH, and exercise. For all 3 assessments, the LSCI presented with higher flux values than the LDF for both boys and men (p
