Posture and Scapular Muscles

I just finished off my review of last weeks journals.  I have chatted about what I do in a previous post.  I talk about it in my 6 Must Read Journals for Exercise and Injuries .

I came across two articles that are great and will be helpful when it comes to neck pain, shoulder pain, scapular stabilization and poor posture.

Lets get to the two articles.

Can Head Posture Affects Neck Pain, Shoulder Pain and Scapular Muscles?

In this research they assessed the effects of forward head posture in a sitting position on the activity of the scapular upward rotators during loaded isometric shoulder flexion in the sagittal plane.

Three Keys I Got Out of This Articles:

#1 – With forward head posture there increase in EMG (muscle activity) activity in the upper trapezius and lower trapezius and a decrease EMG activity in the serratus anterior during loaded isometric shoulder flexion.

#2 – Forward head posture may contribute to neck and shoulder pain during loaded shoulder flexion in sitting.  This can be an issue for all of us.  Poor head posture could be lead to neck pain and shoulder pain when driving, working and being at our computers.

#3 – Neutral head position is advantageous in reducing upper and lower trapezius activity and enhancing serratus anterior activity as compared with forward head posture during loaded shoulder flexion

Where to Get More Details:

For those that are research geeks like me, here is the reference to the article.

Weon JH, Oh JS, Cynn HS, Kim YW, Kwon OY, Yi CH. (2010). Influence of forward head posture on scapular upward rotators during isometric shoulder flexion. J Bodyw Mov Ther. 2010 Oct;14(4):367-74. Epub 2009 Jul 22.

Can Stretching Help with Rounded Shoulders and Scapular Stabilizers?

In this article they performed pectoralis minor soft tissue mobilization and self-stretching of pectoralis minor.

Three Keys I Got Out of This Articles:

#1 – Pectoralis minor soft tissue mobilization and self-stretching of pectoralis mior significantly reduced rounded shoulder posture.

#2 – Rounded shoulder posture remained reduced after 2 weeks of a single treatment.

#3 – Lower trapezius strength improved when rounded shoulder posture improved.

If you want more information, I would dig in the Exercises For Injuries blog, I have done some other posts in the past.

Other areas you can get more information is:

Scapular Stabilization Exercise Program – This is program that I use with clients to help them over come shoulder pain.

Core Stability of the Shoulder – This is a live course where I go into more detail when it comes to scapular muscles.

Postural Assessment & Exercise Prescription – This is a live course where I go through assessing posture and exercises for postural conditions.

That is it.

Take care.
