Direct Chin-tuck Against Resistance (dCTAR) to improve swallowing

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study tests a modified chin-tuck exercise (dCTAR) that combines resistive chin tuck with swallowing to strengthen the suprahyoid muscles and promote forward-upward hyoid‑larynx movement. Researchers will recruit both adults with post-stroke dysphagia and healthy control participants and perform dCTAR while measuring muscle contraction and hyoid-larynx displacement. Outcome measures include ultrasound and functional swallowing metrics, and the protocol will explore how tongue strength and bite force relate to the treatment effect. The design aims to confirm prior single-case observations that dCTAR can improve cricopharyngeal relaxation and bolus passage.
