Introduction: I will bring you the treatment of waist and shoulder injury when playing badminton. I hope I can help you. Thank you for reading.

First of all, shoulder injury.

In badminton activities, shoulder soft tissue injuries are easy to occur, among which rotator cuff injuries are the most common, accounting for about 80% of shoulder injuries. The rotator cuff injury accounts for about 14% of the total badminton injury.

(1) Etiology and Pathology:

1. rotator cuff injury occurred, and some of the injured people were caused by an acute injury, and then they continued to be injured because they could not get timely, reasonable and thorough treatment, and even gradually turned into chronic injuries.

2. Some injured people have no obvious history of trauma, which is due to local overload and repeated abrasion or involvement of rotator cuff tendons, which makes them slightly injured, gradually strained and degenerated.

3. Problems or mistakes in technical movements, insufficient warm-up, poor shoulder muscles and poor flexibility of shoulder joints are also some factors that promote rotator cuff injury.

(2) Symptoms and diagnosis:

1. Shoulder pain

The pain is mostly in the lateral shoulder and can radiate to the upper part of deltoid muscle or neck. Shoulder abduction or internal and external rotation often causes pain.

2. Pain arc

From 10 degree to 120 degree, there is pain in the shoulder abduction arc, and the pain disappears after exceeding 120 degree. Pain occurs when the shoulder drops below 120 degrees.

Step 3: Be gentle.

There is tenderness at the greater tubercle of humerus under acromion.

Step 4 expand

Acute patients may have local swelling.

5. Abduction and external rotation resistance tests were positive.

(3) Handling and post-injury recovery exercises:

1. Physical therapy, acupuncture, massage, external application of band-aid or local drug injection can all achieve good results.

2. Patients with acute injuries should keep their upper arms in a 30-degree abduction posture. Patients with acute injury or acute attack of chronic injury should rest properly. Pause strenuous spinning activities or special technical exercises outside the shoulder range.

3. After the acute phase is over, you should start practicing the rotation and rotation of the shoulder joint.

4. When practicing after injury, you should first practice upper limb drooping and relaxation, and then gradually increase the angle of shoulder lifting to practice. After being basically painless, you can carry out weight-bearing exercises and gradually transition to specialized exercises. People with chronic diseases can engage in shoulder activities, but you should avoid suspicious actions that cause pain or aggravate injuries.

5. In special exercises, you can do some movements with lower difficulty and intensity requirements first, or change the style of some exercise methods or technical movements to control the local load in special exercises.

6. In post-injury training and rehabilitation, attention should be paid to developing the strength and flexibility of the small muscle group of the shoulder strap. When strengthening the muscle strength training of rotator cuff muscles, it is appropriate to carry out static weight-bearing exercises with upper limb abduction of 80-90 degrees.

7. Pay attention to the development of shoulder muscle strength and shoulder flexibility, especially to strengthen the practice of small shoulder muscle groups.

8. In order to strengthen the muscle strength of the arrow step, you can use the elbow flexion and load-bearing static exercise with upper limb abduction of 80-90 degrees.

9. Negative weight is suitable for people, and gradually increases for 30 seconds to one minute or until it can't be persisted.

Second, the waist injury

This kind of injury refers to the soft tissue injury of the muscles, fascia, ligament or intervertebral joint of the waist (hip), commonly known as? Lumbar muscle strain? . Most people with chronic low back pain in badminton belong to this disease (about 60%), accounting for about. 1 1% of the total injuries in badminton.

(1) Etiology and Pathology:

Most of the student players are gradually formed due to fatigue accumulation, local strain or chronic minor injuries. However, if the waist activity is too frequent, the load is too large or too concentrated, such as a sudden burst of strength beyond the bearing capacity of the trunk, the action is beyond the functional range of the spine, and the muscle strength is poor (such as excessive stretching of the spine or striding left and right when taking off and spiking, moving back and forth to return the ball, excessive torsion of the trunk, etc.). ), it is easy to cause acute injury, but after the waist injury, if it is not cured in time, it will not pay attention to self-protection during training.

(2) Symptoms and diagnosis:

1. Pain

Minor injuries are often painless, and I feel low back pain later or the next morning. Do you feel the pain after a serious injury, even at the moment of sprain? Broken waist? Or there is a noise, and the pain is more severe. If low back pain is accompanied by radiation pain, numbness in legs or feet, and the pain is aggravated when the pressure in the chest and abdomen changes (such as coughing, sneezing and defecation), it may be lumbar disc herniation.

2. The physiological curvature of the spine changes, and lateral curvature may occur, and the curvature of the lumbar spine decreases or disappears.

3. Lumbar dyskinesia and muscle spasm

Such as back muscle strain, pain in bending and lateral flexion, and wound pain in resisting stretching spine activities.

4. The injured part generally has definite tenderness.

5. The spinous process is curved

Patients with sprained or dislocated intervertebral joints and prolapse of intervertebral disc nucleus pulposus are often accompanied by spinous process deviating from the midline.

(3) Handling and post-injury recovery exercises:

1. Physical therapy: acupuncture, massage, new drugs for external use to treat trauma, drugs for internal use to treat traumatic injuries, and painkillers when necessary.

During acute pain, you should stay in bed except necessary treatment to avoid serious injury and strain.

3. In the post-injury rehabilitation exercise, it is necessary to use a wide belt for protection and to combine training with treatment. If the back pain gets worse after training, you should practice temporarily and pay attention to rest. If there is no obvious aggravation after practice, you can practice as planned.

4. Rehabilitation exercise should focus on strengthening the strength and flexibility of trunk muscles, and at the same time pay attention to the exercise of related muscles (such as abdominal muscles and bilateral trunk muscles). ). In addition, local preparation activities should be done before practice, and relaxation and recovery should be done after practice, such as hot compress, massage and stretching.

5. Be fully prepared to improve the strength and coordination of waist muscles.

6. Pay attention, don't completely relax your muscles when you spike, and keep a certain degree of tension.

7. Strengthen waist muscle strength and stretching exercise, and strengthen abdominal muscle exercise at the same time. Strengthening these muscles can avoid self-injury, and can also protect the spine and avoid injuries to the spine and ligaments.
