We have discussed in an earlier entry how our posture can affect the position of our pelvic organs, shifting them slightly forward to sit over the top of our pubic bone when we are in neutral spine. It makes sense to recognize how the position of our pelvis can affect our pelvic floor muscles and our pelvic organs, but how can our rounded shoulders effect our pelvic floor function?
To connect these two areas of our body, we have to take a good look at our abdominal and pelvic cavities.
The areas of our pelvis and our abdomen are one continuous body cavity. This is important to realize because as we take up space within our abdomen, it directly affects our pelvic cavity and its contents. Our diaphragm is continuously descending and ascending with every breath we take, taking up space as it descends and giving it back as it ascends. When we breathe in and our diaphragm draws down within our abdomen, we normally accommodate this by expanding our chest and our lower ri...
My shoulder hurts...is it osteoarthritis?
Osteoarthritis is a very common problem. Most people know someone who is dealing with arthritis of at least one joint. Spine, hips, knees, and hands are the most common places for osteoarthritis to cause symptoms. However, any joint can be affected and a common question I hear when a patient presents with shoulder pain is: Do I have arthritis?
First, a bit of anatomy -- the shoulder is composed of two separate joints:
(1) the acromioclavicular joint where the collarbone meets the shoulder bone (2) the glenohumeral joint where the ball of the humerus articulates with the shoulder blade (scapula). Both joints can be affected by osteoarthritis. It is relatively uncommon for osteoarthritis to develop in the glenohumeral joint without a history of trauma or previous injury. We'll discuss that in a minute. First, let's review the acromioclavicular joint.
Causes of Shoulder Pain Besides Arthritis The glenohumeral joint is the most mobile j...
"Separation" of the acromioclavicular (AC) joint, where the end of the collarbone meets the shoulder blade, is actually a sprain of the ligaments that connect the two bones. "Separation" is an old medical term that has been applied to the widening of the space between the bones. Since this problem involves ligaments, it really should be called a sprain. AC separation is typically an injury of young, active people who fall on the shoulder. Most commonly, it occurs when a person lands on the point of the shoulder, driving the shoulder blade down relative to the clavicle. Patients often tell of being thrown over the handlebars when bicycling, being tackled while playing football, or being upended while skiing. As with sprains , there are degrees of severity. Weight lifters, in particular those who do bench presses, often get AC separation. It can also occur in other situations where lifting occurs, or with injury such as falling on the shoulder. A mild, or first-degree, s...
