- ItemExercise and symptom monitoring with a mobile device.(2007-01-22) Nguyen, Huong Q; Wolpin, Seth; Chiang, Kuan-Chun; Cuenco, DorAnne; Carrieri-Kohlman, VirginiaMobile PDA phone devices allow remote monitoring of clinical and behavioral parameters However passively expecting patients to use these devices may lead to low response rates Our study aimed at collecting exercise and symptom data from an older clinical population of patients with COPD employed push technology principles by delivering automated prompts to patients in an effort to increase response rates We found acceptable response rates with subjects preferring to have prompts delivered to coincide with their exercise activity though usability issues had adverse effects on response rates and time
- ItemPilot study of a cell phone-based exercise persistence intervention post-rehabilitation for COPD.(2009-09-14) Nguyen, Huong Q; Gill, Dawn P; Wolpin, Seth; Steele, Bonnie G; Benditt, Joshua OOBJECTIVE To determine the feasibility and efficacy of a six month cell phone based exercise persistence intervention for patients with chronic obstructive pulmonary disease COPD following pulmonary rehabilitation METHODS Participants who completed a two week run in were randomly assigned to either MOBILE Coached n 9 or MOBILE Self Monitored n 8 All participants met with a nurse to develop an individualized exercise plan were issued a pedometer and exercise booklet and instructed to continue to log their daily exercise and symptoms MOBILE Coached also received weekly reinforcement text messages on their cell phones reports of worsening symptoms were automatically flagged for follow up Usability and satisfaction were assessed Participants completed incremental cycle and six minute walk 6MW tests wore an activity monitor for 14 days and reported their health related quality of life HRQL at baseline three and six months RESULTS The sample had a mean age of 68 11 and forced expiratory volume in one second 18 predicted Participants reported that logging their exercise and symptoms FEV 1 of 40 was easy and that keeping track of their exercise helped them remain active There were no differences between groups over time in maximal workload 6MW distance or HRQL p 0 05 however MOBILE Self Monitored increased total steps day whereas MOBILE Coached logged fewer steps over six months p 0 04 CONCLUSIONS We showed that it is feasible to deliver a cell phone based exercise persistence intervention to patients with COPD post rehabilitation and that the addition of coaching appeared to be no better than self monitoring The latter finding needs to be interpreted with caution since this was a purely exploratory study TRIAL REGISTRATION ClinicalTrials gov NCT00373932
