Purpose: To explore the feasibility of a non-pharmacological cough control therapy (CCT) customized for a client with interstitial lung disease (ILD). Client Description: An 83-year-old female with hypersensitivity pneumonitis, and chronic cough for 18 years treated previously with pharmacological treatment for the underlying lung disease and gastroesophageal reflux disease, as well as lozenges and breathing and relaxation strategies. Intervention: Four cough education and self-management sessions (45–60 minutes each) facilitated by a physiotherapist and speech-language pathologist via videoconference were conducted. Session topics included mechanisms of cough in ILD, breathing and larynx role in cough control, trigger identification, cough suppression and control strategies, and psychosocial support towards behaviour change using motivational interviewing. Measures and Outcome: The following assessments were conducted prior to and one week after the intervention: semi-structured interviews, Leicester Cough Questionnaire, King’s Brief Interstitial Lung Disease questionnaire, Functional Assessment of Chronic Illness Therapy Fatigue Scale, modified Borg Scale for severity and intensity of cough, and the Global Rating of Change Questionnaire. Implications: Implementing the CCT was feasible. The client reported increased perceived cough control, a reduction in exhaustion from coughing bouts, and a better understanding of the mechanisms behind cough management and suppression. Improvements were also observed in cough-related quality of life, severity, and intensity.
Background: Manual percussion is used during airway clearance sessions for children with cystic fibrosis. Use of percussor cups can assist manual chest physiotherapy percussion when the treatment is too taxing, or the adult hand is too large. The Canadian distribution for the usual commercial percussor was recently discontinued. The McMaster Manufacturing Research Institute (MMRI) was approached to produce two percussor cup prototypes as potential alternatives. The objective of this study was to evaluate the useability, satisfaction, preference, and safety of the MMRI percussor cups compared to the Smiths Palm Cup® Percussor. Methods: Participants were allocated to two groups based on age. Order of percussor cup use was randomized; caregivers used each percussor cup for 2 consecutive days. Data collection included: demographics, the Quebec User Evaluation of Satisfaction with assistive Technology 2.0, the Pictorial Single-Item Usability Scale, adverse effect report, overall satisfaction ratings and top percussor cup ranking. Results: Twenty-five caregivers and their children enrolled in and completed the study. The MMRI narrow handle percussor prototype, regardless of cup size, was comparable in usability, safety and effectiveness. This can be a locally sourced, innovative solution in Canada for a pediatric percussor cup. Conclusions: All percussor types were favourably reported across metrics examining usability, safety, and effectiveness, apart from the MMRI small cup, wide handle prototype. Overall, the MMRI wide handle prototype was the least preferred, regardless of cup size, while the MMRI narrow handle prototype was comparable to the Smiths Palm Cup® Percussor across all metrics, regardless of cup size.
