Individuals with incomplete symptom relief after CP botulinum toxin (BTX) injection have few treatment options, including repeat BTX injection, dilation, or myotomy. Investigators sought to explore behavioral intervention to facilitate eructation retraining for individuals with incomplete response to CP BTX injections.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This is a retrospective case series of seven individuals with R\u2010CPD who experienced incomplete symptom resolution following injection or experienced symptom recurrence after BTX wore off. They participated in speech\u2010language pathology intervention focused on training patients to achieve a body position that facilitates eructation, called the Behavioral Eructation Retraining Protocol (BERP). Alongside counseling and education, BERP includes teaching the patient to achieve a position with the following features: laryngeal lowering, jaw protrusion, head turn and tuck, and torso anchoring.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Six of the seven patients achieved durable R\u2010CPD symptom resolution with a combination of CP BTX injection and BERP therapy.
