There were 29 subjects with an overall decrease in blood flow after passive hallux adduction (gray dashed line); 16 subjects had an overall increase in blood flow after passive hallux adduction (black solid line). Blood flow is represented by the 42 cardiac cycles before passive hallux adduction and 46 cardiac cycles during passive hallux adduction. Dotted black line crossing the center of the x-axis indicates the start of passive hallux adduction
