Objective: The aim of the current study was to investigate the suprahyoid muscle activation during isometric chin-tuck exercises in different body positions. Methods: Thirty-two healthyvolunteers were enrolled. Suprahyoid muscle activation was recorded with surface EMG sensors placed under the chin. Isometric Shaker Exercise (SE) and isometric chin-tuck exercises were performed in five different body positions for 3 repetitions. Maximum voluntary isometric contraction (MVC) of the suprahyoid muscles was recorded. The normalization procedure was applied by proportioning the maximum suprahyoid muscle activation recorded during each exercise to the MVC, and recorded as a percentage (MVC%). Results: Significantly higher suprahyoid muscle activation was detected during isometric SE compared to isometric chin-tuck exercises in supine and prone press up on elbows positions (p< .008). Suprahyoid muscle activation was found to be similar during isometric SE and isometric chin-tuck exercises in sitting, quadruped and prone positions (p> .008). Conclusions: In conclusion, similar suprahyoid muscle activation was obtained during isometric chin-tuck exercises in sitting, quadruped and prone positions as during isometric SE. Thus, isometric chin-tuck exercises in these positions could be used as an alternative option to increase suprahyoid muscle activation with the possible potential for less fatigue and better patient compliance during dysphagia management.
