A pressure therapy system includes an air pump; a pneumatic line pressurized by the air pump; and a cuff in fluid communication with the pneumatic line, the cuff including flaps sized and shaped to extend around a user's limb, a first chamber and a second chamber separated fluidly by the cuff from the first chamber, wherein the pneumatic line splits into first and second line segments or openings, the first line segment or opening communicating fluidly with the first separated chamber, the second line segment or opening communicating fluidly with the second separated chamber, and wherein the second line segment or opening or a pathway of the cuff leading to the second separated chamber includes a flow restricting structure that delays pressurized air from reaching the second chamber relative to the first chamber.
