Online First articles are published online before they appear in a regular issue of Physical Therapy (PTJ). PTJ publishes 2 types of Online First articles: Author manuscripts: PDF versions of manuscripts that have been peer-reviewed and accepted for publication but have not yet been copyedited or typeset. This allows PTJ readers almost immediate access to accepted papers. Page proofs: edited and typeset versions of articles that incorporate any author corrections and replace the original author manuscript.

Abstract Background: Most inspiratory muscle training (IMT) interventions in patients with COPD have been implemented as fully supervised daily training for 30 minutes with controlled training loads using mechanical threshold loading (MTL) devices. Recently, an electronic tapered flow resistive loading (TFRL) device was introduced that has a different loading profile and stores training data during IMT sessions. Objective: We aimed to compare the efficacy of a brief, largely unsupervised IMT protocol, conducted using either traditional MTL or TFRL on inspiratory muscle function in patients with COPD. Design: Twenty clinically stable patients with inspiratory muscle weakness, participating in a pulmonary rehabilitation program, were randomly allocated to perform eight weeks of either MTL- or TFRL-IMT. Methods: Patients performed two daily home-based IMT sessions of 30 breaths (3-5 minutes per session) at the highest tolerable intensity, supported by twice weekly supervised sessions. Compliance, progression of training intensity, increases in maximal inspiratory mouth pressure (Pi,max) and endurance capacity of inspiratory muscles (T,lim) were evaluated. Results: More than 90% of IMT sessions were completed in both groups. The TFRL group tolerated higher loads during the final three weeks of the IMT program (all p
