“…Few randomized controlled trials of rehabilitation have included patients with equivalent levels of disability because such patients have considerable difficulty attending regular outpatient programmes. Two noncontrolled rehabilitation studies have suggested that patients with more impaired baseline exercise performance were likely to achieve greater percentage improvements in exercise performance after rehabilitation [20,21]. However, the two studies described in the meta-analysis by LACASSE et al [8], which showed the smallest change in exercise performance compared to controls after rehabilitation, recruited patients of equal severity to the present patient group, when assessed in terms of absolute FEV1 levels [22,23].…”

“…Therefore, one should not exclude patients with severe dyspnea from participating in exercise training on this basis alone. Patients with a greater degree of ventilatory reserve (minute ventilation measuring [VE]/maximum voluntary ventilation) achieve greater improvements in exercise capacity following training compared to patients with lesser reserve [53,54], particularly if they also have impaired peripheral muscle strength prior to training [54]. Inspiratory muscle strength (the maximal inspiratory muscle pressure a patient can generate during an inspiratory effort, or PImax) is another predictor of gains made with exercise training [54].…”

“…In fact, previous studies considered the inclusion of smokers 11,12,30,31 . The negative and nihilistic psychological profile of many of these patients 29 and its possible influence on adherence to the program and relapse of ex-smokers have been cited as possible deterrents to their inclusion in PR.…”
