Then turn the ankle joint outward to check the degree of medial ligament injury. 5. Front drawer test: Hold the upper end of the ankle joint with one hand and push it backward, while holding the heel with the other hand and pulling it forward to check whether the range of motion becomes larger (compare with the uninjured side). Third, how to sprain the foot? Principle The foot is sprained after being pressed by gravity or impacted, resulting in soft tissue damage and capillary rupture leading to blood flowing freely at the sprain and accumulating at the sprain, which is why the sprained foot is dark purple and swollen. Treatment 1, immediately after the sprain to take ice, is the injured part of the blood circulation is slowed down, so that the blood accumulation is less, try to reduce the severity of the injury. Invaded in cold water or cold towel on the affected area, 10-20 minutes each time, once every 6 hours, can constrict blood vessels, reduce swelling and pain. 2, the initial stage of sprain, no internal medicine, should not be applied externally to activate the blood of drugs, do not use alcohol, safflower oil or ointment, because these will make the affected area hot, the effect is equivalent to hot compress, its main role is vasodilatation, increase local blood flow, improve microcirculation, and improve the pain threshold to reduce pain, so as to avoid more blood flow, swelling greater, if necessary, with a little “good fast “After 24 hours, take some Yunnan Baiyao, bruise pills, blood circulation and pain relief, and then apply Wuhu Dan externally to reduce the swelling without internal and external medication. 3.After 24 hours, hot compress is needed to accelerate local blood circulation and absorb the exudate in the tissue gap as soon as possible, so as to reduce pain. After 24 hours after the injury, physical therapy can be used, along with acupuncture and massage, but for those with large swelling, avoid heavy manual stimulation. Rub the painful points around the ankle joint with the palm of your hand or fingers for about 10 minutes. Then shake the ankle joint from side to side 10-15 times.
