Previous literature reporting differences in swallowing mechanics associated with stroke.

Landmark	Authors	Relevant Finding
Hyoid	Bingjie et al [11]	reduced vertical movement in aspirating versus non-aspirating stroke patients horizontal showed no significant difference between any group—stroke or healthy
	Paik et al [15]	no significant difference for vertical movement decreased anterior movement in dysphagic stroke patients as compared to normal
	Kim et al [16]	slightly decreased but non-significant difference in aspirating versus non-aspirating stroke patients in vertical and horizontal directions
	Seo et al [17]	non-significant decreases in movement for non-recovered stroke aspirators compared to recovered
Larynx	Bingjie et al [11]	reduced vertical displacement in aspirating versus non-aspirating stroke patients
Hyolaryngeal complex	Han et al	penetration-aspiration status predicted reduced hyolaryngeal elevation in stroke survivors
