Smart Shoulders

Our shoulder joints have the greatest range of motion of any of the musculoskeletal joints in our bodies. The shoulder joint is really two joints, the glenohumeral joint between the arm bone (humerus) and the shoulder blade (scapula) and the acromioclavicular joint between the acromion (a bony projection off the scapula) and the collarbone (clavicle). The glenohumeral joint is a ball-and-socket joint and the acromioclavicular joint is a gliding joint.

Acting together, these joints enable the shoulder to achieve a full 360º of motion in both the frontal (side to side) and sagittal (front and back) three-dimensional planes. The important caveat is that this extensive freedom of motion comes with a price: the shoulder not only has the most mobility, but is also the most unstable joint in the body.

The glenohumeral joint may be easily dislocated, most typically by a fall on an outstretched arm. The ligaments of the acromioclavicular joint are easily sprained and the joint itself is easily dislocated. Acromioclavicular joint injuries may be described as "AC separations". Overall, injuries to the shoulder joint are common, most frequently experienced by people participating in exercise activities and sports and by older people as a result of a fall.

The shoulder joint has built-in protection in the form of the four muscles comprising the rotator cuff, the supraspinatus, infraspinatus, teres minor, and subscapularis.1 The rotator cuff muscles participate in all shoulder joint and upper arm motions and provide stabilization to the shoulder as the joint moves through three-dimensional space. But the rotator cuff muscle group is itself subject to injury (muscle tears) and degeneration as a person ages of the tendons that attach the muscles to the shoulder and arm bones.

Thus, the shoulder joint needs additional protections to maintain its structural integrity and mechanical performance.

In days gone by, people did demanding physical work every day, automatically providing training and resilience to the anatomical components of the shoulder. But in the 21st century, with the decline of the farming and manufacturing sectors and the rise of the service economy, most people no longer engage in actual physical work. As a result, most of us require regular vigorous exercise to maintain physical fitness and good health. With specific respect to the shoulder, upper body strength training exercises will help provide the necessary activity and mobility to ensure ongoing functionality of our shoulder joints. 2,3

As well, obtaining regular chiropractic care helps ensure that our spines are working properly, providing effective mechanical support to our shoulder joints, and that our nerve systems are working at high levels to coordinate all the physiological activities necessary to our long-term health and well-being.

Reviews By Our Satisfied Patients

  • "I first came to see Dr. Canzano about neck and back pain. Dr. Canzano came highly recommended from a wonderful friend of mine who was also a patient. I was in constant pain and had chronic headaches and migraines. I was also taking a lot of pain medication which was only masking my problems. Dr. Canzano's holistic approach to treatment has been a very positive and rewarding one for me. Her advice about diet, nutrition, and exercise has been invaluable to me.

    This is a very special practice -- more like good friends or family. It is a warm, friendly and peaceful place that nurtures the whole person -- mind, body and spirit. Shirl's healing hands and welcoming personality are a critical part of the practice. She is a gifted massage therapist with incredible skills and intuition.

    I have recommended many friends and family members and continue to do so. I honestly don't know what I would do without the care this practice provides."

  • "I came to see Dr. Canzano because of shoulder pain and headaches. I was experiencing decreased activity and concentration. After a few visits, my co-workers started commenting that I was smiling again! I feel better generally when I have regular adjustments."

  • "I was searching for an Activator chiropractor. I had chronic and debilitating neck pain from too many auto accidents. My experience at Canzano Chiropractic has been incredible. Sometimes the adjustments give immediate relief. The nurturing, healing environment, the whole health counseling, massage and alternative healthcare give me whole body healing.

    Canzano Chiropractic offers me a holistic alternative to healthcare, giving myself and my body the assistance to heal. They care about the well being of their patients."
