Treatment and/or prevention of medical conditions via compression
Methods and systems for dynamic compression of venous tissue enable improved blood movement in the extremities. In accordance with an exemplary embodiment, a pressure pad provides a compressive force to a portion of the human body. The pressure pad is successively withdrawn and re-pressed against the body. In this manner, prevention and/or treatment of various medical conditions may be achieved, for example restless leg syndrome, edema, plantar fasciitis, deep vein thrombosis, pulmonary embolism, venous insufficiency, wound care, and/or the like.
1. A method of treating plantar fasciitis, comprising:
moving, by a foot compression system completely contained within an item of footwear, a non-bendable pressure pad a first time to bring the pressure pad into contact with a foot of a patient to stretch the plantar fascia;
moving, by the foot compression system, the pressure pad a second time to bring the pressure pad out of contact with the foot to allow the plantar fascia to relax; and
moving, by the foot compression system, the pressure pad a third time to bring the pressure pad into contact with the foot to stretch the plantar fascia,
wherein the moving the non-bendable pressure pad a first time, a second time, and a third time occurs when the patient is not walking.
2. The method of claim 1 , wherein the pressure pad is held in contact with the foot to stretch the plantar fascia for a duration of between 1 seconds and 5 seconds.
3. A method of treating plantar fasciitis, comprising:
moving, by a foot compression system, a non-bendable pressure pad a first time to bring the pressure pad into contact with a foot of a patient to stretch the plantar fascia;
moving, by the foot compression system, the pressure pad a second time to bring the pressure pad out of contact with the foot to allow the plantar fascia to relax; and
moving, by the foot compression system, the pressure pad a third time to bring the pressure pad into contact with the foot to stretch the plantar fascia,
wherein the foot compression system is completely contained within an item of footwear, and
wherein the foot compression system comprises:
a motor coupled to the pressure pad via a gear; and
a slip clutch coupling the pressure pad and the motor, the slip clutch configured to allow the pressure pad to retract responsive to an applied force exceeding a predetermined value.
4. A method of treating restless leg syndrome, comprising:
moving, by a foot compression system completely contained within an item of footwear, a non-bendable pressure pad a first time to bring the pressure pad into contact with a foot of a patient to stimulate the foot;
moving, by the foot compression system, the pressure pad a second time to bring the pressure pad out of contact with the foot; and
moving, by the foot compression system, the pressure pad a third time to bring the pressure pad into contact with the foot to stimulate the foot,
wherein the moving the non-bendable pressure pad a first time, a second time, and a third time occurs when the patient is not walking.
5. The method of claim 4 , wherein the foot compression system is used to bring the pressure pad into contact with the foot and out of contact with the foot during at least a portion of the period from between about 3 hours before the patient retires to bed to about 1 hour before the patient retires to bed.
6. The method of claim 4 , wherein the delay between the moving the pressure pad the first time and the moving the pressure pad the second time is between about 20 seconds and about 30 seconds.
7. A method of treating deep vein thrombosis, comprising:
moving, by a foot compression system completely contained within an item of footwear, a non-bendable pressure pad a first time to bring the pressure pad into contact with a foot of a patient to compress a portion of the foot;
moving, by the foot compression system, the pressure pad a second time to bring the pressure pad out of contact with the foot to allow the portion of the foot to at least partially refill with blood; and
moving, by the foot compression system, the pressure pad a third time to bring the pressure pad into contact with the foot to compress the portion of the foot,
wherein the moving the non-bendable pressure pad a first time, a second time, and a third time occurs when the patient is not walking.
8. The method of claim 7 , wherein the moving the pressure pad into contact with the foot results in a peak femoral venous velocity of at least 30 centimeters per second.
9. The method of claim 7 , wherein the foot compression system is configured to prevent extension of the pressure pad responsive to an indication that the foot compression system has been moved within a predetermined time period.
10. A method of treating a medical condition selected from a group comprising deep vein thrombosis, edema, restless leg syndrome, venous insufficiency, plantar fasciitis, or a wound, comprising:
moving, by a compression system completely contained within an item of footwear, a non-bendable pressure pad a first time to bring the pressure pad into contact with a portion of a human body to compress the portion of the human body;
moving, by the compression system, the pressure pad a second time to bring the pressure pad out of contact with the portion of a human body to allow the portion of the human body to at least partially refill with blood; and
moving, by the compression system, the pressure pad a third time to bring the pressure pad into contact with the portion of the human body to compress the portion of the human body,
wherein the moving the non-bendable pressure pad a first time, a second time, and a third time occurs when the patient is not walking.
11. The method of claim 10 , wherein the portion of the human body is a foot.
12. A method of preventing a pulmonary embolism, comprising:
moving, by a compression system completely contained within an item of footwear, a non-bendable pressure pad a first time to bring the pressure pad into contact with a portion of a human body to compress the portion of the human body;
moving, by the compression system, the pressure pad a second time to bring the pressure pad out of contact with the portion of a human body to allow the portion of the human body to at least partially refill with blood; and
moving, by the compression system, the pressure pad a third time to bring the pressure pad into contact with the portion of the human body to compress the portion of the human body,
wherein the moving the non-bendable pressure pad a first time, a second time, and a third time occurs when the patient is not walking.
13. The method of claim 12 , wherein the portion of the human body is the foot.
