Rib cage mobility directly influences how well the chest expands during inspiration, so the most effective approaches are those that directly address the ribs and their surrounding fascia. Rib raising targets the rib angles and costovertebral joints, helping the thoracic cage open wider with each breath. Myofascial techniques release restrictions in the thoracic fascia and intercostal musculature, removing barriers to rib motion and improving overall chest expansion and diaphragmatic efficiency. Together, these methods enhance rib cage mobility and respiratory mechanics by directly acting on the structures that move with breathing. Other options don’t focus on the rib cage itself. HVLA to the thoracic spine may improve general spinal mobility but isn’t specifically aimed at improving rib articulation and chest expansion. Deep tissue work on the lower limbs and ultrasound therapy without manual contact don’t impact the thoracic cage or breathing mechanics.
