Exercise training in patients with chronic respiratory failure due to kyphoscoliosis: a randomized controlled trial.

Background: Research has provided evidence for the safety, feasibility, and efficacy of exercise training in patients with COPD. However, little is known about the impact of exercise training in patients with chronic respiratory failure due to kyphoscoliosis. We evaluated the effect of an exercise training program on exercise capacity, muscle strength, dyspnea, and quality-of-life indices in subjects with chronic respiratory failure due to kyphoscoliosis.

Factors associated with quality of life in patients with chronic respiratory failure due to kyphoscoliosis.

Objectives: Patients with chronic respiratory failure due to kyphoscoliosis (CHRF-KS) constitute a specific population with impaired health-related quality of life (HRQL). Thus far, no studies have examined factors related to HRQL. The objective of the present study was to identify clinical, functional and exertion-related factors associated with HRQL.

Shuttle walking versus maximal cycle testing: clinical correlates in patients with kyphoscoliosis.

A cross-sectional prospective design was used to compare the effectiveness of the shuttle walking test (SWT) and the maximal cycle ergometry test (CET) to assess the functional capacity of patients with chronic hypercapnic respiratory failure due to severe kyphoscoliosis. Twenty-four patients completed both the SWT and CET. Heart rate, blood pressure, leg fatigue, chest pain and dyspnea (Borg's scale) were measured immediately after each test.
