Motor Imagery Practice to Improve Respiratory and Cough Function.
Cara Donohue
PMID 40009179WHAT IT FOUND
Five weeks of imagining cough or expiratory exercises improved peak cough flow in healthy adults, but did not change expiratory pressure.
High adherence suggests this mental practice is feasible, though evidence of effectiveness is preliminary.
Key findings
01Motor imagery practice of voluntary cough and expiratory muscle strength training was feasible, with 95% adherence to repetitions and 91% attendance at telehealth sessions.
02Across both groups, significant increases were found in peak expiratory flow measured by handheld device (+13.7 L/min) and cough spirometry (+0.71 L/s), but no other pulmonary or cough measures improved significantly.
03The expiratory muscle strength training group showed no statistically significant improvements in any outcome measure, including maximum expiratory pressure.

What it does not show
The sample was small (n=19 completed) and consisted of healthy, young adults, which limits generalizability to patients with respiratory or swallowing impairments. The study lacked a control group, making it difficult to attribute changes solely to motor imagery rather than natural variation or learning effects. Multiple comparisons were not controlled for, increasing the risk of false-positive findings. No instrumental swallowing assessments were performed, so the impact on actual dysphagia outcomes is unknown.
Declared interests
The study was funded by start-up funds, with no commercial conflicts of interest declared.
The easy way to misread this
Do not assume this mental practice improves breathing muscle strength. The study found no significant change in maximum expiratory pressure, even in the group specifically practicing EMST, and results were from healthy adults who may have had little room for improvement.
