The findings of the study was amazing. They found that the prevalence of rotator cuff tears was:
- 2.9% in those with ideal posture
- 65.8% in those with Kyphotic-lordotic posture (big thoracic and lumbar curves)
- 54.3% in those with flat back posture
- 48.9% in those with swayback type posture (pelvis shifts forward and shoulders shift back)
They concluded that postural abnormality represented an independent predictor of both symptomatic and asymptomatic rotator cuff tears.
What to make of this
These results really back up what the video above shows and hopefully, what you felt.
When your are in good posture, your shoulders are going to function like they are supposed to. They will move freely and as the study shows, your risk of a rotator cuff injury is very low.
If however, you have postural abnormalities, your risk of having a rotator cuff tear rises to almost 66% with some postures.
To me this shows how important posture is not only for a good functioning spine and nervous system, but also healthy shoulders. If you have shoulder pain or discomfort, whilst you are dealing with that, it will also be important to work on correcting your posture. My previous videos on hanging, both passive and active, can help with both of these. Chiropractic care could also be a way of helping improve posture. If you would like to find out more about how chiropractic care could help, please let me know.
Note: Some of the people in this study had no symptoms, even though they had a rotator cuff tear. If you have postural abnormalities, it would be worthwhile working on your posture, even if you have no shoulder pain. As we are always told, prevention is better than cure.
