The reason for this system is to allow for maximum movement and has very small joint contact zone. This essentially means that your shoulder is quite unstable. That is why your shoulder and neck muscles are so vital to a normally functioning shoulder.
In most cases, if you are suffering shoulder pain it is because your muscles are simply not strong enough or they are uncoordinated. The small rotator cuff muscles are often over-powered from the larger and strong muscles. Both of these dysfunctions can be normalised after a quality assessment and injury-specific exercises.
Often shoulder surgery is NOT NEEDED. Even if it was recommended as the first alternative. It is important to have an Active Release Technique (A.R.T.) certified therapist to do an assessment BEFORE surgery.
Dr. Derek at Fit Chiropractic can localize the issue and conservatively treat the injury and avoid painful surgery if possible. Also, a rehab program to strengthen the tissue can be catered to each specific injury.
