The use of our arms are an everyday activity, and often handedness or pain can cause significant contradiction to relief of these limitations. The shoulder joint (Glenohumeral Joint) is severely complex in being convoluted with a significant amount of tendinous insertions, to the humoral head and the humerus itself.
The shoulder is comprised of the rotator cuff muscles; Supraspinatus, Infraspinatus, Teres Minor and Subscapularis. All of these are extremely important for upper extremity mobility. Running over these muscles are the insertion of both the bicep tendons (Long and short bicep heads) as well as the shoulder “protector” the Deltoid muscles (Anterior, Middle and Posterior Deltoid), which makes the shoulder one of the most convoluted joints in the body.
Injury or strain to one of these creates huge limitations for using the arm on same side of injury and that causes immediate strain on the opposing shoulder for completion of activities of daily living (ADL).
Any shoulder injury can be a start of something bigger than any person should have to endure. A simple fall or slip down the steps with an outstretched or guarding arm, can be the origin of something much worse if not managed correctly in the long term. Some of the resulting issues are; Tension headaches, “pinched nerve” sensation, neck pain, back pain and many more. These are the few I’ve listed of many compensating symptoms found from straining the shoulder complex.
Recovery of rotator cuff strain involves immediate ice and rest of the joint to not overuse (especially in dominant handedness cases). Ice for 10 minutes on and 10 minutes off repeating 3 times per day for acute cases. If pain subsided do simple isolation exercises LOW WEIGHT for muscle recovery. If pain persists consult a relevant practitioner.
