This systematic review investigates the effect of swallowing interventions (e.g., swallowing maneuvers, swallowing postures, oral-motor exercises) on hyoid bone displacement as observed via videofluoroscopy in individuals with dysphagia secondary to a variety of etiologies (e.g., stroke, Parkinson’s, head and neck cancer).

Traditional swallowing exercises combined with the super-supraglottic swallow were found to improve superior hyoid bone displacement.
The Shaker exercise program did not significantly influence hyoid bone displacement; however, it did improve other parameters and was shown to reduce post-swallow aspiration.
The effortful swallow, supraglottic swallow, and chin tuck did not show significant effects on hyoid bone displacement; however, the chin tuck combined with the supraglottic swallow demonstrated a reduction in penetration.
Volume and consistency of the bolus had variable effects on hyoid bone displacement in individuals with dysphagia.
Neuromuscular electrical stimulation was found to limit the hyoid bone displacement or cause the hyoid bone to move inferiorly.
