Abstract

Background: Whole-body vibration exercises (WBVE), inserted on the Pulmonary rehabilitation (PR) program of chronic obstructive pulmonary disease (COPD) individuals can improve the exercise capacity, postural control and muscle power. This study evaluated the functionality of the COPD submitted to WBVE, comparing two different postures on the vibrating platform. Methods: The WBVE protocol (5 bouts, 1 time per week for 6 weeks, 25Hz, 2.5 mm of peak-to-peak displacement) were performed on a side-alternating vibratory platform (SAVP). Two different postures were adopted: the Siting group (SitG) were sitting in a chair with the hands maintained in contact with their knees and the Stand group (StandG) were standing with 30º knee flexion on the SAVP; both positing the foot on the base of the SAVP. The functionality was assessed by the Short Physical Performance Battery (SPPB). Results: Thirty eight COPD individuals completed the WBVE protocol. Significant (p ≤0.05) improves was presented by the SitG (balance test p=0.03; 3mSG test p=0.05; 5CS test p=0.04; total score p=0.003) and StandG (3mSG test p=0.02). The body mass index (BMI) and dyspnea had a negative correlation (r=-0.10, p=0.65 and r=-0.25, p=0.26) and positive correlation (r=0.19, p=0.44 and 0.10, p=0.69) with the total score of the SPPB, for SitG and StandG respectively. Conclusion: WBVE can be considered a safe, suitable kind of exercise on the PR program for COPD individuals, improving their functional capacity and minimizing the exacerbation of symptoms such as dyspnea. Additionally, the SPPB showed an adequate tool to identify the functional parameters of this population.
