After a knee injury, whether it is a cartilage injury, chondromalacia patella or meniscal problems, it is necessary to perform static squat exercises, so what is the correct way to do it? Now introduced as follows: the patient’s legs apart, the distance between the two feet is slightly wider than the shoulders, the body to maintain an upright position, can not lean forward, then the knees began to bend squat. The bending angle of the knees varies according to the patient’s physical condition and muscle strength. If the patient’s physical condition is good, good thigh muscle strength, squatting angle can reach 90 degrees, if the patient is weak, thigh muscle strength is weak, both knees can be lightly flexed, this time the half squat position is higher, the patient more effort. You can later increase your knee flexion angle as your exercise progresses and your thigh muscle strength increases. Each patient will have a painful angle when squatting, some squatting to 30 degrees pain, some squatting to 60 degrees pain, or 40 degrees pain, it is best to avoid the painful angle when practicing, and vice versa. If early due to lack of muscle strength, it is recommended that the upper body and hips against the wall, with the wall to reduce the pressure on the upper body. A squat time varies greatly from person to person, are squatting until they can not hold on. Rest a minute between two squats, do not rest too long. Then practice the second squat, so that week after week, 30 minutes in a row for the day of a squat exercise. Depending on your physical condition, decide how many times you want to practice. Practice 1-3 times a day.
