The sternalis muscle is a little known muscle located at the sternum. This muscle seems to be vestigial in that it doesn’t have a known function. In originates on the superior portion of the sternum and the upper part of the pectoralis muscle. It’s insertion is the cartilage of ribs 3-7, or sometimes the sheath of the rectus abdominis, or the lower part of pectoralis major. Even though this muscle doesn’t seem to have a purpose anymore it can still harbour trigger points. These points will cause pain to be felt intensely deep in the sternum, with spillover pain radiating down the inside of the arm.
Your shoulder is one of the most complex joints in your body. It is surrounded and supported by a complex network of nerves, tendons, muscles, and ligaments. Many of these structures tie back to your spine or mid-back and neck. Your posture, or position, directly impacts the motion of your shoulder and scapula. Long hours at a desk or computer can lead to postural changes and muscle imbalances. Poor posture and a forward head position can lead to “upper cross syndrome.” Upper cross syndrome is an imbalance of the muscles in your upper back, neck, and shoulder that can lead to neck, back, and shoulder pain with restricted range of motion.
Why it Matters:
Whether it’s working at a computer, long hours in a car, or using a tablet/smartphone, just about everyone is susceptible to developing upper cross syndrome. However, you don’t need to suffer or change your career to find relief. A combination of Chiropractic adjustments, stretching, and specific postural exercises can make a huge impact on your ability to stay happy and healthy. Taking short breaks every 20-30 minutes to lightly extend your arms and move your neck through a comfortable range of motion will help your body “reset” while working. Also, periodic Chiropractic adjustments will help you maintain an optimal range of motion and reduce restrictions that can occur in your spinal joints.
– The shoulder is one of the most complex joints in the human body.
– Your posture greatly impacts the ability of your shoulders to move through their full range of motion.
– It’s important to address the neck and mid-back when treating a shoulder injury.
Upper cross syndrome is one of the most common conditions we see in our practice. Far too many people suffer from pain for years before discovering Chiropractic care. Millions of people end up taking medications just to get through the day. Like you, we believe there is a better way. Take a flyer for our upcoming workshop and share it with a friend at work. We are excited to share how the challenges of upper cross syndrome can be overcome without drugs or surgery!

The supraspinatus muscle is one of the muscles that makes up your rotator cuff. It attaches from the scapula to the humerus. It functions mainly to laterally rotate the arm as well as stabilize the shoulder joint. It also assists in abduction of the arm. This muscle can often harbour stubborn trigger points. These points refer pain into the shoulder, down the arm, into the elbow, and even into the forearm if irritated enough. These points can be effectively treated with trigger point massage therapy.
A very common muscle to become overloaded and damaged, and thus develop trigger points, is the pectoralis major muscle. This is the muscle that makes up the chest. It’s main functions are adduction and internal rotation at the shoulder. Poor rounded shoulder posture is a common cause of pec tightness and trigger points. trigger points in this muscle will produce pain felt into the front of the shoulder, the chest, and down the medial arm. If these symptoms occur in the left pec it can mimick heart pain. In women, these points can be a cause of breast pain and nipple hypersensitivity.
