Estimating maximum work rate during incremental cycle ergometry testing from six-minute walk distance in patients with chronic obstructive pulmonary disease.
To develop a predictive equation to permit estimation of the maximum work rate (Wmax) achieved during an incremental cycle ergometry test from the measurement of 6-minute walk distance (6MWD) and its derivative, 6-minute walk work, which is the product of 6MWD and body weight. ⋯ Wmax can be estimated from equations based on measurements of 6MWD or 6-minute walk work. The estimate of Wmax derived from either equation may provide a basis on which to prescribe cycle ergometry training work rates that comply with the current guidelines for pulmonary rehabilitation.

Intraobserver reliability of angular and linear measurements of scapular position in subjects with and without symptoms.
To assess intraobserver reliability of angular and linear clinical measurements of scapular position. ⋯ Repeated-measure (ICC(2,3)) results were more reliable than single-measure (ICC(2,1)) results. Very good to excellent intraobserver reliability was demonstrated for the angular and linear measurements of interest in both shoulders of subjects with and without symptoms. The 2 SE results provide guidance about the error associated with the individual measurements and will assist the clinician determining whether a change in the static position of the scapula has occurred as a result of intervention or over time. (National Research Register identifier N0060148286.).

Randomized Controlled TrialIntermittent positive-pressure breathing effects in patients with high spinal cord injury.
To determine whether intermittent positive-pressure breathing (IPPB) improved lung compliance, work of breathing, and respiratory function in patients with recent high spinal cord injury (SCI). ⋯ IPPB produced no immediate or long-term improvements in lung function or ventilatory mechanics in patients with recent SCI. (ClinicalTrials.gov identifier: NCT00476866.).

Controlled Clinical TrialClassifying subgroups of chronic low back pain patients based on lifting patterns.
To compare self-reported measures of chronic lower back pain (CLBP) patients who were assigned to 2 subgroups based on their lifting patterns performed during a repetitive lifting task. ⋯ A classification system based on lifting patterns identified 2 CLBP subgroups that were significantly different on lifting and self-reported measures, indicating the importance of physical functioning measures in classification systems.

Randomized Controlled Trial Comparative StudyA targeted home- and center-based exercise program for people after total hip replacement: a randomized clinical trial.
To examine the physical function, gait, and quality of life of patients after total hip replacement (THR) randomly assigned to either a targeted home- or center-based exercise program. ⋯ The targeted strengthening program was effective for both the home- and center-based groups. No group differences were found in the majority of the outcome measures. This finding is important because it shows that THR patients can achieve significant improvements through a targeted strengthening program delivered at a center or at home.
