BackgroundPatients with Chronic Obstructive Pulmonary Disease (COPD) reduce physical activity to avoid the onset of breathlessness. Fan therapy (FT) can reduce breathlessness at rest, but the efficacy of FT during exercise remains unknown in this population.AimTo investigate 1) the effect of FT on exercise-induced breathlessness and post-exercise recovery time in patients with COPD, 2) the acceptability of FT during exercise 3) to assess the reproducibility of any observed improvements in outcome measures.MethodsA pilot single-centre randomised controlled crossover, open (non-masked) trial (NCT031375424) of FT versus no FT during 6-minute walk test (6MWT) in patients with COPD and a Modified Medical Research Council (mMRC) dyspnoea score ≥2. Breathlessness intensity was quantified pre and on termination of the 6MWT, using the numerical rating scale (NRS) (0–10). Post-exertional recovery time was measured; defined as the time taken to return to baseline NRS breathlessness score. Oxygen saturation and heart rate were measure pre and post the 6MWT.ResultsFourteen patients with COPD completed the trial per protocol (4=male, 10=female; median age (interquartile range)=66.50 (60.75–73.5) years); mMRC dyspoena 3 (2–3)). Fan therapy resulted in lower exercise-induced breathlessness (Δ NRS; Δ mBORG) [within-individual differences in medians (WIDiM)=−1.00, IQR=−2.00 to −0.50, p<0.01; WIDiM=−0.25, IQR=−2.00 to 0.00, p=0.02], greater distance walked (metres) during the 6MWT [WIDiM=21.25, IQR=12.75 to 31.88, p<0.01], and improved post-exertional breathlessness (NRS) recovery time [WIDiM=−10.00, IQR=−78.75 to 50.00, p<0.01]. Fan therapy was deemed to be acceptable by 92% of participants.ConclusionFan therapy was acceptable and provided symptomatic relief to patients with COPD during exercise. These data will inform larger pilot studies and efficacy studies of FT during exercise.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.
