Abstract
Background: physical activity (PA) has been reported to be reduced in severe chronic obstructive pulmonary disease (COPD) and Pulmonary Rehabilitation is well known to improve exercise capacity in those subjects.
Aim: to examine the variation in physical activity after a Pulmonary Rehabilitation Program (PRP) in COPD patients .
We examined 28 patients (mean age 68.7 yrs) with moderate-severe COPD(FEV1 55.1%).They wore the Armband Sensorwear for 6 consecutive days before and after a 10-week outpatient PRP.
Total Day Energy Expenditure(TDEE) and Active Energy Expenditure (AEE) significantly improved after PRP in the whole sample (TDEE :227+/-419 cal prePRP vs 2350+/-131 cal postPRP; p=0.026, AEE :298.7+/-220.3 cal prePRP vs 538.6+/-483.4 cal postPRP; p=0.03).
When we divided the patients according to the response to the 6MWT (responders >/= 36 non-responders< 36 mt or of the improvement of the total score of SGRQ (responders>/= 4, non-responders <4),we observed that non-responders in both group significantly improved in physical activity parameters.
In some patients with moderate-to-severe COPD a PRP may improve some parameters of physical activity measured with the Armband Sensorwear although the same treatment is no effective in terms of 6MWT or SGRQ.
