Background:The six-minute walking distance (6MWD) test has demonstrated validity and reliability to assess changes in functional capacity following pulmonary rehabilitation in patients with chronic obstructive lung disease. However, no attempt has been made to establish an iterative measurement of 6MWD during the overall period of pulmonary rehabilitation. Therefore, the aim of this study was to evaluate the impact of a twelve-week rehabilitation program on the iterative weekly measurement of 6MWD in chronic obstructive pulmonary disease (COPD) patients and healthy subjects.Methods:Twenty-six patients with COPD and nine age-matched healthy subjects were studied. Measurements were taken at baseline and after twelve weeks except for the 6MWD. The exercise measurements included a six-minute walking test (6MWT) and an incremental exercise test. Oxygen saturation, heart rate, and dyspnea will be monitored during all these tests.Results:At baseline there were significant differences between groups, except in age, body mass index, and oxygen saturation. After 12 weeks, there was no significant change in lung function in patients with COPD and healthy subjects. The 6MWD, peak oxygen uptake V̇O2peak and anaerobic threshold increased significantly after training in both groups (P < 0.01). The averaged trace of the 6MWD of patients with COPD and healthy subjects was followed-up respectively by a logarithmic and linear fitting. 6MWD showed a plateau after eight weeks in patients with COPD, however, it increased continually overall in healthy subjects.Conclusion:Both patients with COPD and healthy subjects demonstrated functional responses to training but with somewhat different patterns in quality of the improvement of the 6MWD.

“…[1][2][3][4][5][6][7] These mechanisms have the potential to alter inputs into the perceptual processes for the sensation of breathlessness. 9,49 The greatest mean improvements in the 6MWD were for subjects no longer volunteering descriptors of air hunger (increase of 46 m) or work/effort (increase of 47 m, see Table 3).…”

“…1,2 Exercise of sufficient duration and intensity is associated with reduction in skeletal muscle dysfunction, may enhance mechanical efficiency of physical activities, and may reduce or delay the onset of dynamic hyperinflation during exercise and reduce sensitivity to dyspnea. [1][2][3][4][5][6][7] While participation in CPRP has been shown to reduce the intensity of dyspnea and impact of dyspnea on health related quality of life, 2 whether participation in CPRP moderates the qualitative sensation of dyspnea is less clear.…”

“…While there is debate concerning the optimal frequency and duration of exercise training within CPRP, a number of guidelines recommend that exercise training for people with COPD participating in CPRP should occur 3 times a week for a duration of at least 6 -12 weeks. 1,3,4,5,20 These 2 studies 18,19 indicate that the intensity and, possibly, the type of breathlessness sensation can be modified by participation in CPRP of shorter duration.…”

BACKGROUND: This study investigated whether descriptors of breathlessness differed after participation in an 8 week pulmonary rehabilitation program and whether changes in sensory quality would be reflected in responsiveness to pulmonary rehabilitation. METHODS: People with COPD provided descriptors for their sensation of breathlessness before and after an 8 week pulmonary rehabilitation program. Primary outcomes for responsiveness to pulmonary rehabilitation were the 6 minute walk distance (6MWD) and the St George Respiratory questionnaire. Significant proportional shifts for sensory categories after rehabilitation were identified using the McNemar test. Random effects mixed modeling was used to determine significance of differences for primary outcomes between subjects modifying or not modifying descriptors of breathlessness. RESULTS: Of the 107 people referred to the pulmonary rehabilitation program, 94 met the spirometric criteria for COPD, with 58 having data for pre and post assessments (36 males, 71 ؎ 9 years old, percent of predicted FEV 1 58 ؎ 24%). A significant proportion of subjects reduced descriptors of air hunger (P ‫؍‬ .03, odds ratio 0.31, 95% CI 0.09 -0.89) and depressed, regret, helpless (P ‫؍‬ .04, odds ratio 0.36, 95% CI 0.10 -1.05) following rehabilitation. Subjects reducing their use of descriptors of air hunger had greater improvements in the 6MWD after rehabilitation (P ‫؍‬ .006, mean increase 46 m). CONCLUSIONS: The sensory quality of breathlessness was modified for approximately one third of subjects after pulmonary rehabilitation, with significant improvements in the 6MWD for subjects who reduced their use of descriptors of air hunger.

“…A study conducted by Green et al [79] concluded that for patients recruited from the same centre, those undertaking a seven week training programme had better health outcomes than a group who undertook a 4 week programme. Solanes et al [80] claimed that a minimum of 8 weeks of rehabilitation (with three sessions per week) is necessary for improvements in health outcomes to be observed. [86] suggested that other reasons include not feeling comfortable in taking part in group activities, not feeling safe with health professionals who are conducting rehabilitation programmes, and personal beliefs or experiences about their illness.…”

Duration of pulmonary rehabilitation to achieve a plateau in quality of life and walk test in COPD

Abstract: A program of 3 weekly 3-h sessions of outpatient pulmonary rehabilitation program should last at least 8 weeks in order to achieve optimal HRQL and exercise tolerance for most patients.
