Benefits of Whole-Body Vibration to People With COPD
A total of 15 participants with GOLD Stage II COPD and one participant with GOLD Stage III COPD were recruited to the trial with 100% compliance to the both interventions (Figure 1). Demographic and disease characteristics are presented in Table 1. Acute and long-term results are shown in Table 2.

Flow of participation in the trial.
There was no acute effect of WBV or SWBV on rating of perceived dyspnea and oxygen saturation (p > 0.05) (Table 1). The WBV intervention increased heart rate by as much as 12 beats.min (p ≤ 0.05). The SWBV intervention increased heart rate by as much as 7 beats.min (p > 0.05).
Whole-body vibration improved performance of the TUG (13%) and 5-chair tests (18%) (p = 0.01). Across the first three weeks of WBV, TUG improvement was 0.5 sec (Partial η = 0.28, power = 0.99) and then an additional 0.9 sec (Partial η = 0.41, power = 0.95) after six weeks. Whole-body vibration also improved performance of the 5-chair test after three weeks by 2.1 sec (Partial η = 0.50, power = 0.95) and at Week 6 by 1.4 sec (Partial η = 0.49, power = 0.94). There was no effect of SWBV on simulated ADLs (p > 0.33). Performance was within ± 0.2 sec for both the TUG (2%) and 5-chair (1%) tests. Kinematic variables of gait improved after WBV (p = 0.01). Effect size was at least Partial η = 0.24 for stride length, Partial η = 0.14 for stride time, and Partial η = 0.72 for stride velocity. There was no effect of SWBV in kinematic variables of gait (p > 0.10).
