Translation of the Leicester Cough Questionnaire into Swedish, and validity and reliability in chronic obstructive pulmonary disease.

Purpose: The purpose of this study was to translate and culturally adapt the Leicester Cough Questionnaire into Swedish and to test the validity and reliability of the Swedish version, in patients with chronic obstructive pulmonary disease.

Methods: The original Leicester Cough Questionnaire was translated into Swedish by a method, which followed an established forward-backward procedure, including cross-cultural adaptation and pretest. To test the validity of the final version of Leicester Cough Questionnaire in Swedish, the St George's Respiratory Questionnaire and the COPD Assessment Test were used (n =112) and to test reliability, the questionnaire was repeated (n = 86).

Improved oxygenation during standing performance of deep breathing exercises with positive expiratory pressure after cardiac surgery: A randomized controlled trial.

Objective: Breathing exercises after cardiac surgery are often performed in a sitting position. It is unknown whether oxygenation would be better in the standing position. The aim of this study was to evaluate oxygenation and subjective breathing ability during sitting vs standing performance of deep breathing exercises on the second day after cardiac surgery.

Creatine supplementation and physical training in patients with COPD: a double blind, placebo-controlled study.

Study Objectives: Patients with chronic obstructive pulmonary disease (COPD) have low exercise capacity and low content of high energetic phosphates in their skeletal muscles. The aim of the present study was to investigate whether creatine supplementation together with exercise training may increase physical performance compared with exercise training in patients with COPD.

Design: In a randomized, double-blind, placebo-controlled study, 23 patients with COPD (forced expiratory volume in one second [FEV1] < 70% of predicted) were randomized to oral creatine (n = 13) or placebo (n = 10) supplementation during an 8-week rehabilitation programme including exercise training.

Performance changes for patients with chronic obstructive pulmonary disease on long-term oxygen therapy after physiotherapy.

Objective: To investigate whether patients with chronic obstructive pulmonary disease on long-term oxygen therapy would benefit from an early 8-week rehabilitation programme in terms of exercise performance, health-related quality of life and activities of daily living.

Methods: Two weeks after onset of oxygen therapy, 20 patients were randomized to rehabilitation (group A) or not (group B). Exercise performance was measured using a 6-minute walking test.
