Persistent tension and soreness on the posterior side of the shoulder and neck (location as shown in the figure), worst at night before bedtime and relieved in the morning. Postural analysis: 1. forward head shift; 2. forward shoulder extension; 3. rib cage exostosis; 4. protruding abdomen; 5. flattened hips; 6. forward weight shift; 7. elevated right iliac crest; 8. longer right leg. Possible influences: Shortened muscles: sternocleidomastoid, suboccipital, pectoralis major, pectoralis minor, subclavius Elongated muscles: middle and lower trapezius, rhomboids Weak muscles: transverse abdominis, internal intercostal muscles, gluteus maximus Muscle strength test: weakness of gluteus maximus, middle and lower trapezius, rhomboids found Shoulder abduction movement pattern test: premature activation of right trapezius, delayed suprascapular gyration Shoulder palpation This is a typical case of tension pain due to overstretching of the posterior shoulder and neck. The patient had pain due to a long period of ambulation and study, with internal rotation of the humerus and forward extension of the shoulder girdle resulting in shortening of the anterior muscles and overstretching of the posterior muscles, due to being stretched throughout the day, so although it was severe before going to bed, it was relieved when getting up in the morning after a night’s rest, and then Then it starts to enter the next vicious cycle of shortening and lengthening. There are also problems with long and short legs and pelvic tilt, which are not yet symptomatic, but are potentially risky. Solutions: 1) Adjust the sacroiliac joints to restore the length of the legs 2) Pull the pectoralis minor 3) Release the pectoralis minor 3) Release the subclavian muscle 4) Pull the sternocleidomastoid muscle 5) Pull the suboccipital muscle 6) Strengthen the cervical flexor group 7) Activate the transversus abdominis 8) Lower the ribs 9) Y.L.W.T. exercises to strengthen the lower and middle trapezius muscles 10) Activate the glutes (although there is no direct effect on the shoulder and neck pain itself. But it has a positive impact on the overall posture and functional activities). 11. Rehabilitation results Head recovery, shoulder peak posterior shift, weight posterior shift (observe the position of arm and trouser seam), pelvic position tends to be centered. The patient felt that the tension in the back side of the shoulder and neck disappeared, and the shoulder was relaxed and pain-free. Note: Subsequent self-training should be continued, adhere to the above exercise methods, and pay attention to the change of posture and avoid maintaining a certain posture for too long.
