PMID 40425763WHAT IT FOUND
Older inpatients who could perform fewer head lifts from a lying position had more food and liquid left in their throat after swallowing.
This simple test, requiring no special equipment, correlates with swallowing residue.
Key findings
01The number of head lift repetitions was independently associated with pharyngeal residuals in both the valleculae and pyriform sinus, even after adjusting for age and sex.
02Time to maintain head lift was associated with vallecular residue but not pyriform sinus residue in the adjusted model.
03Jaw-opening force was not significantly associated with either measure of pharyngeal residue.

What it does not show
Single-center study with a small sample size (50 participants), limiting generalizability. The same evaluator assessed head lift strength and calculated NRRS scores, introducing potential bias despite inter-rater reliability checks. The head lift test measures muscular endurance rather than maximal strength, and it is unclear how much sternocleidomastoid fatigue confounds the assessment of suprahyoid function. Participants were hospitalized inpatients; findings may not apply to outpatient populations. Median residue scores were low, which may have reduced the sensitivity to detect associations with jaw-opening force.

The easy way to misread this
Do not interpret the head lift test as a direct measure of swallowing muscle strength. The test primarily reflects muscular endurance, and the association with residue is correlational, not causal. A low score indicates risk, not a definitive diagnosis of dysphagia severity.
