Interventions that included ET and PA counseling during PR were effective strategies to improve PA in COPD
BACKGROUND Physical inactivity is associated with poor outcomes in COPD , and as a result , interventions to improve physical activity ( PA ) are a current research focus .
However , many trials have been small and inconclusive .
OBJECTIVE The aim of this systematic review and meta- analysis was to study the effects of r and omized controlled trials ( RCTs ) targeting PA in COPD .
Pilot study of a cell phone-based exercise persistence intervention post-rehabilitation for COPD
Objective 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 r and omly 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 ( FEV1 ) 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 Clinical Trials.gov ( NCT00373932 )
