Here’s another blog from a Mississauga Chiropractor…
Glenohumeral instability can be caused from ligament laxity, muscle imbalances or joint malformation.
- Previous trauma, shoulder pain or dislocation
- Possible pain with certain movements; patient may be able to voluntarily dislocate their own shoulder. (Glenohumeral instability often coexists with other rotator cuff conditions)
- Deltoids and rotator cuff muscles have local trigger points and spasms
- 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:
- Restore the normal shoulder range of motion
- Normalize shoulder strength and dynamic muscle control
c) Improve scapular & clavicular range of motion with stretching and mobilization
- Strengthen parascapular muscles & stretch serratus anterior muscle
- Strengthen the rotator cuff muscles (especially the internal rotators/adductors)
- Strengthen the biceps brachii
- Improve shoulder proprioception
