This document discusses goals and techniques for chest mobilization. The goals are to maintain or improve mobility of the chest wall, trunk, and shoulders when affected by tightness or other issues. This can improve ventilation. Techniques described include stretching tight muscles while taking deep breaths, and leaning forward during expiration to push internal organs up against the diaphragm. Specific chest mobilization techniques involve movements like bending, lateral flexion, rotation, arm movements, and pulling the knees to the chest while breathing. Contraindications include rib fractures, bone cancer, tuberculosis, osteoporosis, hernias, severe pain, and unstable vital signs.
