Rib Flares

Addressing rib flares is clinically worthwhile when they co-occur with mobility limitations or reduced movement variability, as correcting rib cage position can expand movement capability. Rib flare may reduce when tucking and breathing mechanics are coached well. Rib flares and the infrasternal angle are distinct concepts that should not be conflated because they represent different things requiring different treatments. Rib flares occur in both narrow and wide infrasternal angle individuals, but differ meaningfully in appearance, underlying muscular deficiency, and required intervention. Thoracic kyphosis is described as a normal spinal curve rather than inherently pathological. The article prioritizes restoring dynamic rib cage behavior over simply pulling the ribs down. Rib flare is a visible forward prominence of the lower rib cage associated with anterior pelvic orientation, reduced abdominal activity, and a C-shaped spinal presentation. The infrasternal angle is more important than the visible flare alone when assessing rib flare positioning. A rib flare is a protrusion of the lower rib cage where the ribs visibly stick out when viewed from the side. The root cause of rib f…
