[Stretching training] Do stretching training without pain. Stretching and pulling muscles and fascia training is appropriate, if the symptoms are more serious, improper stretching may add additional damage to the injury. 1, plantar fascia stretching training: the training for plantar fascia stretching, both in the injury period and after rehabilitation is necessary, can be done as a long-term training. Training method: stretching, sitting on the ground or chair, grab the toes with your hands and pull backward until you feel comfortable with the plantar pull, maintain the posture for about 15-30 seconds, and then relax. Repeat the action 5 times as a group, 3 sets of training per day. 2, rolling can training using hard cans or thick sticks as an aid. Practice barefoot on the can with a mild curve, back and forth rolling, slow movements, so that the plantar fully stretched. Each time 3-5 minutes. The difficulty of the training can be enhanced by increasing the force of stepping down. If you use the bottle of ice, or frozen cans can also play the role of ice, the effect is even better. The training is particularly effective when you get up in the morning. 3, passive stretching training (towel pulling training): sitting on the ground, the affected leg will be stretched out in front.

Hold the movement for 15-30 seconds, then relax. Repeat 3 times. The whole pulling process should be gentle and slow to avoid pain. If you find that towel stretching can be done more easily, you can start standing gastrocnemius extension training. 4, standing gastrocnemius extension training: standing facing the wall, the affected leg as far back as possible, arms raised in front of the wall to shoulder level. The front leg knee slightly bent, the body leaned forward. Keep the rear leg straight and keep the heel as far from the ground as possible. When you feel a pulling sensation behind the calf, maintain it for 20-30 seconds. When there is no tension pulling feeling, you can increase the degree of forward leaning until the posterior calf tension appears. Every 3-5 sets, each set of 3 times. 5, step stretching training: If the recovery is better, you can further use step-assisted training to achieve better pulling effect. This training can replace the previous standing gastrocnemius extension training, just do one of them. Training method: Stand with your feet on the edge of the step with your heels off. Both sides of the step should be protected by handrail supports. Press the heel down until there is a pulling sensation at the back of the calf. Hold for 15-20 seconds, 3-5 sets of 3 reps per day. The whole process slowly and gently, if the feeling is not obvious, you can try to put the heel a little lower until there is tension, but do not overdo it. 6, standing position flounder muscle stretching training: training methods: stand facing the wall, so that the affected leg in the back, hands forward at shoulder level to hold the wall. Bend both knees to the squatting position, the heels do not leave the ground. The person leans forward, body weight is applied to the feet, but the heels are never off the ground.
