In clinical practice, if patients often do leg stretching exercise, it can make the human body grow taller, because through leg stretching exercise, it can strengthen or improve the elasticity and toughness of the lower limb muscles, which can accelerate the blood circulation of the lower limb muscles and promote lactic acid metabolism, which can play a role in improving microcirculation. In addition, the exercise of leg stretching can also increase joint stability and stimulate bone growth and development in the bilateral tibial tuberosity epiphysis area, which can make the patient’s body grow taller. In order to make the body taller, auxiliary treatments can be used, such as hot compresses or electrical stimulation on the bilateral tibial tuberosity epiphysis, as well as suspension traction or hyperextension traction, all of which can promote the growth and development of the bones and make the patient’s body taller.
