The methods of posterior thigh stretching are mainly as follows: the first category, which is commonly known as leg press, should do a full warm-up when doing this exercise. When doing the leg press, the patient is asked to lift one side of the foot and place it on a step at the same height as the hip, then the other lower limb remains upright and the upper body slowly moves closer to the raised side of the lower limb, and finally the patient’s jaw is required to be close to the calf on this side, during which the knee joints on both sides are kept straight. The second type of stretching can be practiced in the standing position, requiring the patient to keep both lower limbs together and upright, then slowly leaning the upper body toward the lower body, and finally requiring both upper limbs to touch the ground or the heels of the feet. In the third category, a seated stretch can be taken, and it is best to do this activity on a floor mat to prevent getting cold. The patient should first sit in a seated position with the lower extremities abducted at 120° and the knees straight. At this time, the upper body should be used to slowly approach the lower extremity on one side first, still requiring the lower jaw to touch the lower leg, and then alternate between the two sides. In addition, if the patient is more flexible, he or she can take the splits exercise.
