Effects of the Head Lift and Recline Exercise Regimens on the Neuromuscular Control of Functional Swallowing in Older Adults: An Electromyography Study Revealing Potential Differential Mechanisms.
Trial report in Journal of speech, language, and hearing research : JSLHR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe head lift exercise (HLE) and recline exercise (RE) are rehabilitative exercises that have been shown to elicit similar biomechanical swallowing changes in older adults. However, the neuromuscular mechanisms underlying these changes are unknown and could elucidate the physiological mechanisms these exercises target.
methodA randomized clinical trial with two arms-a 6-week HLE or RE regimen-was conducted. Data were collected on older adults pre- and posttreatment and at 6-week follow-up using videofluoroscopic swallow studies (VFSSs) and surface electromyography (sEMG). Results of the VFSS showing similar hyolaryngeal excursion gains post both regimens have been published. This follow-up study presents the sEMG data and includes data from 18 older adults (age range: 60-82 years; HLE = 9, RE = 9) from the pre- and posttreatment time points. sEMG activity measures (normalized mean amplitude, burst duration, and time to peak sEMG amplitude) were collected from submental muscles during standardized swallow tasks.
resultsNormalized mean amplitude, burst duration, and time to peak amplitude during swallowing did not significantly change posttreatment for either group. Post hoc correlational analysis of percent change between outcome measures from pre- to posttreatment revealed a strong negative relationship between normalized mean amplitude and time to peak amplitude for liquids (
conclusionsIn combination with the Fujiki, Oliver, Malandraki, et al. (2019) results, these findings support that older adults show improvements in anterior and superior hyoid excursion post both HLE and RE without the need for greater submental musculature contraction. The inverse relationship identified post hoc between the percent change of amplitude and time to peak amplitude may indicate different neuromuscular mechanisms for biomechanical gains and needs further exploration for future personalized treatments.
