When you slouch (try it)…your head moves forward and down (requiring you to then look up to keep yours eyes ahead), your back becomes rounded and your shoulders roll forward.
Now sit up as straight as you can…your head moves back and up, your back straightens up and you pull your shoulders back.
Your shoulder is made up of a “ball and socket” joint known as the glenohumeral joint. But did you know that your “shoulder” is also made up of 3 other joints? To complete your shoulder, you have 3 other joints including…
- Scapulothoracic joint (shoulder blade and upper back)
- Acromioclavicular joint (shoulder blade and collar bone)
- Sternoclavicular joint (breast bone and collar bone).
These four joints move in perfect rhythm to allow you to move your arm in any direction you need.
When you slouch, you round your shoulders forward causing compression of ligaments, tendons, nerves and muscles that make up the front of your shoulder and chest. You also change the angles at which those joints mentioned above can move. Poor mobility can lead to overuse, excessive strain and eventually pain in your shoulder. You may feel pain down your arm as well. This can be due to your poor posture!
With just about every activity we do throughout the day our heads are down and our shoulders are rounded forward. This occurs when we sit at our desks, use our cell phones, wash dishes and read a book. Having poor posture has a negative impact on the health of your spine and the surrounding musculature.
Poor posture is almost inevitable, especially after a long day at work or doing chores around the house.
