This systematic review explores studies using biomechanical analysis of hyoid
bone displacement in videofluoroscopy of swallowing as a spatial outcome
parameter to evaluate intervention effects. Two authors independently carried out
the literature search using the electronic databases Embase, PubMed, and Cochrane
Library. Differences in their search findings were settled by discussion.
The search was limited to publications in the English, German, French, Spanish, or
Dutch language. MeSH terms were used, supplemented by free-text words to identify
the most recent publications.
In addition, reference lists were searched by hand.
Only studies using videofluoroscopy to evaluate the biomechanical effects of
swallowing interventions in dysphagic subjects were included in the review. While
the body of literature on measuring hyoid bone displacement in videofluoroscopy
has grown, only 12 studies met the inclusion criteria. Several of the 12 studies
had methodological shortcomings. In general, the conclusions could not be
compared across the studies because of their heterogeneous designs and outcome
measures. Overall, several intervention effect studies reported significant
results. In particular, bolus modification and swallowing maneuvers showed a
greater range of hyoid bone displacement. In light of this review, further
research on hyoid bone displacement as a spatial variable in well-defined patient
populations using well-defined videofluoroscopic protocols to measure intervention effects is recommended.
