Understand the area
The project’s diaphragm research includes a preliminary study using several practitioner-applied techniques. Our interpretation: a combined clinical protocol does not establish the separate effect of one contact, or justify a fixed-duration ball or block hold beneath the ribs. This entry remains a research overview.
Context & cautionsDo not use a body-map marker as a placement instruction. Deep pressure beneath the sternum or ribs is not a published self-care guide here.
Research before a routine
This region currently has an overview and source trail. Our review has not established a suitable general self-pressure guide for this area.
