Variations in Head-Neck Posture and Hyoid Kinematics in Patients With Stroke and Aspiration Risk: A Cross-Sectional Observational Study.
Haipeng Jin, Yanli Huang, Weihong Xiao and 4 others
PMID 41834817WHAT IT FOUND
Stroke patients with high aspiration risk had forward head posture, restricted neck movement, and smaller hyoid displacements than those with low risk.
Poor head-neck posture correlated with reduced hyoid movement, suggesting posture may contribute to swallowing dysfunction.
Key findings
01The high aspiration risk group had significantly smaller craniovertebral angle and more restricted cervical range of motion than the low risk group.
02Hyoid anterior and superior displacements were significantly smaller in the high aspiration risk group compared to the low risk group.
03Pooled analysis showed significant correlations between head-neck posture measures and hyoid displacements.

What it does not show
The sample size was very small, with only 12 patients in each group, limiting the reliability of the findings. The study design was cross-sectional, so it cannot prove that poor posture caused the swallowing problems. Swallowing impairment was assessed only by the Penetration-Aspiration Scale, which measures airway safety but not the full spectrum of dysphagia. The analysis focused only on head-neck posture and did not account for the influence of the shoulders, thoracic spine, or pelvis on swallowing mechanics.
Declared interests
The investigators declared no financial or nonfinancial disclosures.
The easy way to misread this
Do not assume that correcting head-neck posture will improve swallowing function. This study only shows that poor posture and reduced hyoid movement occur together in patients with aspiration risk; it did not test whether treating the posture changes the swallowing outcome.
