The latissimus dorsi has a similar twist, revealing the synergistic relationship between the two muscles. These two broad, strong muscles work together to generate tremendous power, forcibly lowering the arm from an overhead position. Tissue restrictions here often present as an inability to fully flex the shoulder when the torso is fixed. Many clients will arch the back in an effort to extend the range of motion, leading to low-back pain when performing overhead activities. The pectoralis major also keeps the chest erect when the arms are supporting the body's weight. This occurs when pushing up out of a chair, supporting body weight on crutches, or during athletic activities like parallel bars. It also works with the latissimus dorsi and teres major to adduct the shoulder when pulling objects down from overhead or pulling the body up toward a fixed hand, such as when climbing a ladder or rope.

FUNCTIONAL ANATOMY PALPATING THE PECTORALIS MAJOR Positioning: client supine with the arm at the side. 1. Locate the inferior clavicle. 2. Palpate inferiorly along the muscle belly with your palm toward the sternum and costal cartilage. 3. Follow the muscle belly to its attachments on the clavicle, costal cartilage, and sternum, then use a pincer grasp to palpate the anterior border of the axilla. 4. To ensure proper location, the client resists shoulder horizontal adduction. CLIENT HOMEWORK: OVERHEAD CHEST STRETCH 1. Stand or sit up straight. 2. Reach your arms straight overhead and interlace your fingers with the palms facing upward. 3. Raise your arms upward as you press your shoulders downward. 4. Breathe deeply, allowing your chest to relax and open.
