The posture is the same as in Chinese martial arts, horse riding squatting crotch action or called standing pile action, squatting horse stance. The patient’s legs are separated, the distance between the two feet is slightly wider than the shoulders, the body remains in an upright position and cannot lean forward, at which time the knees begin to bend and squat. The bending angle of both 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 the knee flexion 90o, if the patient is weak, weak thigh muscle strength, both knees can be lightly flexed, this time the half squat position is higher, the patient more effort, can be later with the exercise, thigh muscle strength increases, and then increase the knee flexion angle. Each patient will have a painful angle when squatting, some squatting to 30o pain, some squatting to 60o, or 40o pain, practice static squatting best to avoid the pain angle, if squatting to 30o pain, you can continue to squat down to 60o to avoid the 30o pain angle, and vice versa. The duration of a squat varies greatly from person to person, all squatting until they can’t hold on. Rest a minute between two squats, do not rest too long. Then practice the second squat, and so on and so forth, for 30 minutes in a row for the day’s squat practice. Depending on your physical condition, decide how many times you want to practice. Practice 1-3 times a day.
