Lumbar disc bulge generally refers to lumbar disc herniation, and the main exercise methods include, isometric contraction exercises for abdominal muscles and isometric contraction exercises for lumbar back muscles in the acute stage, and aerial cycling exercises, flying swallow exercises, and plate support in the recovery stage. 1. Activity period: In the stage of acute pain, the patient mainly rests in bed and performs the following bed exercises depending on the specific situation. (1) Abdominal muscle isometric contraction exercise: lie on your back, lift your upper body forward and upward to exert force, and slightly flex your lower limbs to facilitate the abdominal muscle to exert force. Hold 30 seconds for 1 time, 10 times for 1 group, 2~3 groups a day. (2) lumbar back muscle isometric contraction exercises: supine position, upper body force pressure bed, just lumbar muscle force, do not cause movement. Keep 30 seconds for 1 time, 10 times 1 group, 2~3 groups a day. 2. Recovery period: the pain is basically relieved at this stage, mainly to strengthen the strength of the lumbar and abdominal muscles, stabilize the lumbar spine and improve lumbar spine mobility, and gradually return to normal and sports. (1) Air bicycle: supine position, legs bent upward, imitating the bicycle movement. (2) Flying Swallow Exercise: prone position, head, both upper limbs, lower limbs as far back as possible, abdominal contact with the bed or cushion area as small as possible, in the shape of a flying swallow. (3) Plate support: prone position, bent elbow, small arm and forefoot palm support the ground, the body off the ground, ears, shoulders, hips, knees, ankles in a straight line, to maintain balance.
