Could Uneven Shoulders Indicate Any Issue? by charlestlee

Uneven shoulders can be observed in a couple of planes. One of the most common observations is when one shoulder looks higher than the other. This could indicate either a structural, muscular or neural imbalance.

Structurally, the patient may have a leg length discrepancy or a scoliosis that causes the shoulders to be raised on one side.

Muscularly, the shoulder blade or scapula has multiple muscles that stabilize it in position. Muscular imbalances can easily occur that cause certain muscles of the scapula to pull it in a certain direction. For example, in many single arm-dominated sports such as baseball or tennis, the dominate arm tends to over-develop the latissmus dorsi which is your ‘wing’ muscle. With more muscular development it actually pulls the shoulder blade down. In standing postures, most of these athletes will look like their shoulder is lower on the same side. This can create problem for the lowered shoulder, especially when the arm is required to repetitively raise over their head. With the shoulder lowered it takes greater work of the opposing muscles to raise the arm overhead. Over time, it can cause poor shoulder mechanics and lead to injury of the shoulder.

When someone has chronic nerve symptoms in their neck and arm due to a radiculopathy or pinched nerve in their neck, many times you may see that the shoulder on the same side looks elevated. This is due to the adaptation of the muscles to shorten or spasm to elevate the shoulder girdle and allows more room for the nerve to conduct. Patient’s with this pattern often feel tight in their neck and upper shoulder. When they try to stretching the muscles it makes their nerve symptoms worse. This happens because the muscle is not tight but in protective spasm keeping the nerve from being injured further. In this case it is important to treat the nerve first before trying to lower the shoulder girdle.

Your Diaphragm – Not Just For Breathing! by charlestlee

Post by Beth Collier PT, DPT, OCS

Most people know that our diaphragms are responsible for allowing us to breathe in and out. Most people also know that fast repetitions of diaphragm contractions manifest as hiccups.  What most people don’t realize is that the diaphragm is actually a part of your core and plays a vitally important role in posture.

Other components of your core muscles include your deep ab and back muscles as well as muscles that make up your pelvic floor. A dysfunction in one part of the core can lead to increase stress on the other remaining muscles groups, which is why core strengthening is emphasized in back pain and incontinence.

As a musician or athlete, it is important to train your diaphragm to be able to withstand the extra stress of increased breathing demand during activities like running, cycling, singing or playing a wind instrument but still be able to contribute to your core strength and postural control.



Musicians With Too Much Flexibility by BCollier

When first learning a musical instrument, it is often the flexibility of a person that gives them an advantage to playing with superior technique.  In the case of hand flexibility, the ability to easily span octaves or assume challenging fingerings make technically demanding pieces seem much more feasible.  However, in cases of extreme mobility, musicians will often revert to firm pressures  to better stabilize their instrument. When firm pressures are applied against a firm surface, often posistions of hyperextension are assumed. Such positions, especially frequently repeated or chronically maintained, put your joints at risk for injury. Contrastingly, many people with extreme joint flexibility will try to brace themselves by co-contracting multiple muscle groups to give a feel of stability. Often, in these cases, the muscles become more subject to injury as they approach a state of fatigue and overuse.  Potential solutions for musicians who suffer from too much joint flexibility include ring splints- as seen in the picture below.  Splints, such as those found at www.silverringsplint.com allow the musician functional use of their fingers, while adding an external support to the joints to prevent injury.

Proper fit and splint selection are essential for best outcomes with assistance in music performance.  Be sure to consult a PT or certified hand therapist to assist you with you decisions!
