Blood clots in the legs need to be treated clinically first, including anticoagulant drugs and surgical treatment to ensure that the clots are stable and there is no risk of dislodgement. After that, you can use metatarsal flexion, dorsiflexion, and encircling to perform exercises. 1. Plantar flexion: lie on your back or sit on the bed, stretch your lower limbs, relax your thighs, inhale, slowly raise your toes, try to keep your toes facing you, keep it for 5 to 10 seconds, then exhale, and then slowly put it down and take a short break. 2. Back stretching: lie on your back or sit on the bed, stretch your lower limbs, relax your legs, slowly tense your toes as you inhale, try to keep your toes down, keep it like this for 5 to 10 seconds, then exhale and slowly put it down, take a rest. 3. Wrap around: lie on your back or sit down, stretch your lower limbs, relax your thighs, and rotate 360 degrees around your ankle joint when you exhale, maximizing the movement as much as possible. This type of activity can promote blood circulation in the patient’s legs, the initial practice should be slightly less force, slowly get used to it and then increase the strength, if you feel pain during the exercise, you can shorten the time and number of exercises. It should be noted that if you can not guarantee the stability of blood clots, it is prohibited to exercise, to avoid causing serious sequelae such as pulmonary embolism. Patients with blood clots in the legs should try to stand less, walk less, and bear less weight, and promptly carry out standardized treatment under the guidance of doctors.
