30 adults, aged 40 and older with mild to moderate COPD, will be recruited for this study. Participants must be willing to continually wear a FitBit activity monitor, have access to a smartphone or Wi-Fi/Data-enabled iPad, and be willing to complete respiratory muscle strength training exercises as well as reports on their smartphone at least 5 times per week for a 6-week period. Participants will be given a bluetooth inhaler device and a training app (RESP-FIT). This application will collect inhaler data and allows patients to self-report their daily symptoms. The goal of this study is to test whether use of the personalized inhaler device with the app strengthens lung function, promotes physical activity, and improves disease symptom self-management in persons with COPD.
RESP-FIT. The RESP-FIT program is a 6-week respiratory muscle strength training intervention adapted from previous respiratory muscle strength training (RMST) training regimens, consisting of 1) five training days/week using combined inspiratory and expiratory muscle training, consisting of breathing in and out against a combine inspiratory and expiratory muscle strength trainer (IMST/EMST), 2) individualized, progress-based text message training reminders and prompts related to timing and intensification calibration, and 3) use of a Fitbit for remote monitoring of physical activity and hours slept at night. Similar to other muscle strength training programs, exercises are done at regular intervals during the week (5 breaths, 5 times a day, 5 days a week; the participant will receive graphical illustration of RESP-FIT training frequency and intensity achieved, and based on their training regimen, will be prompted and/or reinforced via SMS text messaging). As the use of an accelerometer or remote tracking device alone may affect physical activity, a control group will receive only the Fitbit. This study proposes to assess the feasibility and initial efficacy of RMST by obtaining estimates of variability in fatigue secondary to dyspnea, using a technologically-enhanced RESP-FIT intervention. Our overarching hypothesis is that a training regimen consisting of RMST along with technology-enhanced symptom-tracking will decrease dyspnea, dyspnea-related activity avoidance, and fatigue. Additionally, this application proposes to further develop Smartphone Airway Monitoring System (SAMS) which currently integrates EMA probe questions covering COPD symptoms and preventive care use with the new functions, use in an adult population with COPD, video captured training technique and logging of RMST training sessions. Up to thirty adults with COPD (age over 40) will complete the study and use the SAMS app for 6 weeks in the natural environment. We will evaluate the acceptability, feasibility, adherence, and performance of RESP-FIT + SAMS through quantitative methods to further optimize the app and related study procedures for the next phase of testing (i.e., large scale efficacy RCT).

This is a randomized longitudinal controlled observational study. The study will recruit 30 participants and utilize a control group experimental design with dependent pretest and posttest to derive data regarding (1) feasibility and (2) within-participant effect size of the RESP-FIT intervention in terms of satisfaction, use and adherence, technical issues and acceptability, and self-reported symptom severity (dyspnea and fatigue). When completed, 30 adults (15 in each group) will have used SAMS for 6 weeks.

| Change in Fatigue | Change in fatigue (measured with the PROMIS v1.0 Fatigue Scale). The PROMIS Fatigue item banks assess a range of self-reported symptoms, from mild subjective feelings of tiredness to an overwhelming, debilitating, and sustained sense of exhaustion that likely decreases one's ability to execute daily activities and function normally in family or social roles. Fatigue is divided into the experience of fatigue (frequency, duration, and intensity) and the impact of fatigue on physical, mental, and social activities. A higher PROMIS T-score represents more of the concept being measured. For negatively-worded concepts like fatigue, a T-score of 60 is one SD worse than average. | baseline, 6 weeks |
| Dyspnea | Change in difficulty breathing (measured with the PROMIS v1.0 Dyspnea). Participant can select from 5 items evaluating how shortness of breath over the past 7 days affected ability to do various activities (Getting dressed, walking stairs, household chores, or walking fast pace) ranging from "I did not do this," "no difficulty," "a little difficulty," "some difficulty," and "much difficulty." A score of 50 is the average for the general population with a standard deviation of 10 as calibration testing was performed on a large sample of the general population. The dyspnea instruments were calibrated on a sample of adults with COPD, so a score of 50 is the average for people with COPD. For the adult PROMIS Dyspnea Severity 10a short form, a raw score of 10 converts to a T-score of 48.8 with a standard error (SE) of 2.0, for an average dyspnea rating. The T-score can range from 29.7-76.7. A higher score represents more dyspnea being measured. | baseline, 6 weeks |
