What the trial is, and whether it could suit you

This study evaluates whether cognitive load affects inhaler technique in adults with chronic obstructive pulmonary disease (COPD). During a single study visit, participants will complete assessments of cognitive function, mobility, and respiratory status. Dual-task mobility will be assessed using the Timed Up and Go test performed alone and while completing a cognitive task. Inhaler technique will then be evaluated in two conditions: usual inhaler use without an additional task and inhaler use while maintaining a short sequence of digits in working memory. Inhaler technique will be scored using a standardized five-step device-specific checklist, and inhaler use time will also be recorded. The study will examine whether inhaler technique worsens under cognitive load and whether this deterioration is associated with dual-task mobility performance, cognitive function, respiratory symptoms,
