Cognitive load and inhaler technique in COPD

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with COPD will be tested to see if thinking about a small memory task while using their inhaler changes how well they use it. Participants will do a Timed Up and Go test twice—once normally and once while holding a simple memory task in mind. Inhaler technique will be scored with a standard checklist, and inhaler use time will be recorded. The study will explore links between any change in technique under cognitive load and mobility, cognitive function, respiratory symptoms, and functional capacity. No inhaler training or correction will be provided between the two inhaler-use conditions.
