Stretching the inner thigh tendons, the main role of relaxing the tense and spastic inner thigh muscles, improve the range of motion of the hip joint, as follows: 1, relax the tense and spastic inner thigh muscles: can relax the tense and spastic inner thigh muscles, long time standing work or walking for too long, can lead to obvious strain on the inner thigh muscle groups, manifested as local muscle groups spasm, tension, stiffness. By stretching the medial thigh muscle group, the clinical symptoms can be relieved and the patient’s pain symptoms can be significantly reduced. 2, improve the range of motion of the hip joint: by pulling the medial thigh tendon, the range of motion of the hip joint can be improved. If the medial thigh tendon is too tight, it will lead to restricted hip joint activities, especially in patients with femoral head necrosis, whose internal thigh muscles tend to be spastic and tense, and by stretching, the abduction range of hip joint activities can be improved, which is conducive to the recovery of normal life. Therefore, pulling the muscles and tendons of the inner thigh is beneficial to the patient.
