1, quadriceps femoris strength training: supine position, straighten the knee joint, and tighten the muscles in front of the thigh for quadriceps femoris static contraction. Each contraction should be as hard as possible and persist for a long time, so that it is advisable to make the thigh muscles feel sore several times.
2. Straight leg lifting exercise: Lie on your back, lift your lower limbs out of bed for about 30 degrees, hold 10 second, then slowly put them down, rest for a while, and then repeat the training, with 1 0/group every/kloc-0-20 times until the muscles feel sore. In addition, an appropriate amount of sandbags can be tied to the ankle for practice, and the weight of sandbags can gradually increase with the increase of strength.
3. Semi-squat movement against the wall: stand against the wall, bend your knees and hips at least 90 degrees, and do semi-squat movements. Stand up after 10 seconds, and squat after a short rest. Every 10-20 times, for 1 group.
4. Active flexion and extension of lower limb joints without load: supine position, one lower limb is straight, the other lower limb bends knees and lifts hips, so that the thigh is as close to the chest as possible, and then alternately practice the other lower limb.
