Abstract

Abstract: Objective: To investigate the effects of adding whole body vibration (WBV) to routine exercise regimen of pulmonary rehabilitation (PR) on bone strength, lung function and exercise ability of elderly patients with stable chronic obstructive pulmonary disease (COPD) complicated with osteoporosis (OP). Methods: Thirty seven elderly patients with stable COPD were randomly divided into control group (group C, n=12, age: 64.6±3.8 years), conventional PR group (PR group, n=12, age: 66.1±4.9 years), and whole body vibration combined PR group (WP group, n=13, age: 65.5±3.3 years). Before intervention, X-ray and computerized tomography bone scan, bone metabolic markers, pulmonary function, cardiopulmonary exercise, 6-minute walking and isokinetic muscle strength were performed, and then intervened for 36 weeks, three times/week, among which group C subjects were given routine treatment, PR group added aerobic running and static weight resistance on the basis of routine treatment, and WP group added WBV on the basis of PR group intervention. After the intervention, the same indicators were detected. Results: Compared with before the intervention, the pulmonary function indexes of each group were significantly improved after the intervention (P＜0.05), and the bone mineral density and bone microstructure indexes of the patients in the WP group were also significantly improved (P＜0.05). Compared with group C and group PR, the bone mineral density, bone microstructure, parathyroid hormone (PTH), insulin-like growth factor-1 (IGF-1), interleukin-6 (IL-6), osteocalcin (OCN) and other bone metabolism indexes, knee flexion, peak extension torque, fatigue index and muscle strength of patients in WP group were significantly improved (P＜0.05). Conclusion: Adding WBV to the conventional PR regimen can improve the bone strength, lung function and exercise capacity of elderly patients with COPD complicated with OP, and may be able to make up for the deficiency of the current conventional PR regimen for insufficient muscle and bone stimulation.
