Effect of head and neck angle on swallowing dynamics in healthy adults

Key Points

• To investigate how different angles of the head and neck affect the swallowing process in healthy adults.
• Participants were assessed using video fluoroscopy to analyze swallowing dynamics at various head and neck angles.
• Healthy adults were randomly assigned to different head and neck positions during swallowing evaluations.
• Swallowing efficiency improved at a specific head and neck angle compared to neutral position, p<0.05.
• Changes in angle resulted in variations in swallowing timing metrics, indicating biomechanical influence.
