Lower Extremity Strength for Upper Extremity Stability: An Introduction to RedCord and Myofascial Trains
Overhead athletes in any sport are at high risk for shoulder injuries. The common thought to rehabilitate shoulder injuries is to strengthen the rotator cuff musculature, and upper extremities. More modern thought points to hip strength and lower extremity strength to further support the upper body. In the example of weightlifting, force transmission is so high in the upper body, lower body force has to match so as to not get injured, and complete the lift! To further understand on how to train the lower body to provide upper extremity stability, we turn towards myofascial trains.
Before we go through myofascial trains, we must first go over a brief anatomy of the shoulder joint2. We also have to understand what exactly the shoulder’s functions are. The shoulder joint sacrifices stability for mobility, with close to 180 degrees of motion in most individuals. We need to be able to have this amount of motion to reach overhead, grab objects, reach into tight spaces, and of course the snatch and clean and jerk! Despite an increased amount of motion, the shoulder can provide adequate stability when performing the aforementioned functional movements. The shoulder complex is a complicated joint with multiple joints and muscles that have to coordinate to provide efficient biomechanical movement. The AC joint, SC joint, thoracic spine, scapula and glenohumeral joint all have to have the right amount of mobility and muscle control to produce adequate movement. If one or many of these joints is injured or does not have proper range of motion, poor mechanics can occur. Many studies3 point to the thoracic spine as one of the main culprits to shoulder pain, with it being significant in end range shoulder motion. Although, a recent study concluded that thoracic spine manipulation does not alter the mechanics of the shoulder girdle, suggesting that pain re-mapping is occurring following manipulation.4 We need approximately 60 degrees of clavicular posterior rotation, 180 degrees of freedom within the glenohumeral joint, 60-70 degrees of scapular upward rotation, and a variance of degrees in the thoracic spine to complete efficient range of motion. Passive structures such as ligaments, prevent excessive motion, ………………………………………..Read More at Performance Menu
