Venous thrombosis is influenced by Virchow’s triad, and a decrease in venous velocity is considered one of the risk factors. In this study, we examined three foot and leg movements—bending the ankle back and forth (“Bending”), squeezing the toes (“Squeezing”), and massaging and milking the calf (“Milking”)—using healthy volunteers and ultrasound to determine which exercise increased venous velocity the most. The results showed that “Bending” produced the highest velocity, while “Squeezing” produced the lowest. We also compared left and right sides for each exercise, finding that left-side velocity during “Milking” was significantly lower than the right side.
Kodaka et al. (Mon,) studied this question.
