Abstract
Purpose: Mental practice using motor imagery (MP) improves motor strength and
coordination in the upper and lower extremities in clinical patient populations. Its
effectiveness as a rehabilitation tool for patients with lingual weakness is not yet
well understood, nor are the underlying mechanisms within the context of swallow or
lingual MP. Using previously published data on a lingual and MP exercise program, the
objective of this study was to explore how MP of lingual exercise affects cortical
activation in healthy older adults over time and how neural changes correlate with
functional oral pressure outcomes. Method: A prospective randomized controlled study was
previously completed; older healthy participants were randomized to one of four
treatment groups receiving lingual MP, lingual physical practice, a combination of both,
and a sham control. This paper reports descriptive data on cortical activation during
both the physical and mental forms of lingual resistance in a subgroup of 13
participants using functional near-infrared spectroscopy at baseline and after 6 weeks
of the assigned exercise regimen. Results: Aggregated data indicates that participants
who completed 6 weeks of lingual exercise, either in physical or in MP form, had
decreased oxygenated hemoglobin when completing a maximal lingual pressure task.
Conclusions: Some participants in a lingual resistance MP program demonstrated trends
similar to those seen after strength training. Combining MP with physical training may
lead to greater changes in oxygenation compared to a physical or mental training program
alone, although given the small number of participants, it is important not to
overinterpret the results. MP is a promising, innovative approach that may enhance
traditional exercise-based swallowing rehabilitation.
