The endurance time during constant high work-rate exercise (t(LIM)) is used to assess exercise capacity in patients with chronic obstructive pulmonary disease and as an outcome measure for pulmonary rehabilitation. Our study was designed to establish the minimum clinically important difference for the t(LIM). t(LIM) was measured in 105 patients (86 males) before and after an 8-week outpatient p...

OBJECTIVE Although the factors predictive of survival in patients with chronic obstructive pulmonary disease (COPD) have been widely studied, full consensus has yet to be reached. The objective of this study was to further clarify how lung function parameters, exercise tolerance, and quality of life influence survival in patients with COPD. PATIENTS AND METHODS This prospective study included...

The introduction of mistuning in jet-engine bladed disks can lead to large changes in stability and forced response. Even small random mistuning (within the bounds of manufacturing tolerance) can lead to unacceptable response and high-cycle fatigue. Meanwhile, intentional mistuning may improve stability and forced response under manufacturing uncertainty. This paper presents a general framework...

Exercise tolerance in chronic obstructive pulmonary disease (COPD) patients has been shown to be related to airway limitation and dyspnoea, but little is known about the effects of an emotional status on physical performance. We examined 49 COPD patients with a wide spectrum of airway limitation severity and hypoxaemia. Exercise tolerance was evaluated using the Six-minute Walking Distance Test...

the beginning, mid-point and end of study values respectively. There is an apparent tendency or trend for the mean values to progressively decline during the study in the Thllffia group, suggesting the development of resistance. However, when these data are subjected to paired t-testing, a statistical manipulation which tends to find signi6cance in even small deviations, statistical s i g d can...
