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

  • "In 2006, I was scheduled by a Cardiologist to have a Heart Catheterization. I had been having constriction and tightness in my chest, so I sought the opinion of Dr. Hicks. He showed me where my neck was subluxated and told me he was sure an adjustment would remedy my situation. He was right! I felt immediate relief and my symptoms have never returned."
    -Jeannine K.
  • "In May 2010 I had been hit in the head with a softball and had a concussion. Soon after I began having severe migranes and headaches. After two MRI studies, the medical doctor prescribed me Sumatriptan which is a painkiller. I suffered from the migranes for 14 months until I met Dr. Hicks. He gave me my first adjustment and my mom and Dr. Hicks noticed that the color in my face went from pale to pink immediately! My migranes have disappeared and I rarely even get a headache. Thank you Dr. Hicks!"
    -Brenna B. age 17, South Lyon
  • "My husband and I were apprehensive about seeing a Chiropractor but Dr. Hicks put us both at ease. The treatments we have received have helped both of us far beyond our expectations. Not only have the adjustments been beneficial but our eating habits and sleep patterns have greatly improved. Dr. Hicks listens to our concerns and keeps finding ways to improve our well being. Both Joanne and Dr. Hicks have made us feel a part of their family."
    -Elizabeth & A.J.
  • "I have had sinus problems for 25 years. It caused me to lose my voice every year and I love to sing at my church. I was also unable to smell or taste food for years. Now, with regular chiropractic care along with nutritional supplements, I have regained my sense of smell and taste. Also, I have not had to miss singing for my church on Sunday mornings thanks to Dr. Hicks!"
