Here’s another blog from a Mississauga Chiropractor…


Glenohumeral instability can be caused from ligament laxity, muscle imbalances or joint malformation.


  1. Previous trauma, shoulder pain or dislocation
  2. Possible pain with certain movements; patient may be able to voluntarily dislocate      their own shoulder.  (Glenohumeral      instability often coexists with other rotator cuff conditions)
  3. Deltoids and rotator cuff muscles have local trigger points and spasms
  4. There is apprehension with shoulder external rotation, flexion or abduction end ranges.



a)      Initial pain and inflammation should be controlled with rest, ice/heat; if dislocated, it should be reduced ASAP


b)      Once pain is reduced, the goals of conservative treatment should:

  1. Restore the normal shoulder range of motion
  2. Normalize shoulder strength and dynamic muscle control


c)      Improve scapular & clavicular range of motion with stretching and mobilization

  1. Strengthen parascapular muscles & stretch serratus anterior muscle
  2. Strengthen the rotator cuff muscles (especially the internal rotators/adductors)
  3. Strengthen the biceps brachii
  4. Improve shoulder proprioception
