Background and objective To determine if whole body vibration training ( WBVT) improves muscular force and modifies functional capacity parameters in patients with severe chronic obstructive pulmonary disease ( COPD). Methods We performed a randomized controlled trial in the outpatient Physical Medicine and Rehabilitation Department of a general hospital. Sixty stable male patients with COPD and mean forced expiratory volume in 1 s ( FEV1) 34.3% (predicted) were enrolled with 51 patients completing the study. Participants were randomized into two groups: Whole Body Vibration Training Group ( WBVTG), ( n = 26) undergoing three sessions per week for a total of 6 weeks and a Control Group ( CG) ( n = 25) without intervention. The main outcome measures were isokinetic knee flexor and extensor testing in a concentric-concentric regime and exercise capacity measured by the 6-min walking test ( 6MWT). Secondary outcomes were pulmonary muscular assessment with maximum inspiratory pressure ( MIP) and maximum expiratory pressure ( MEP). Results No significant differences were observed between groups in maximum moment of isokinetic knee flexor/extensor testing force in a concentric-concentric regime. In contrast, WBVTG patients showed a significant increase in the 6MWT (81.2 ± 9.2) meters; mean ± SD; P < 0.001). There was also a significant decrease in maximum oxygen desaturation in the 6MWT after 6 weeks of training (3.1 ± 1.1; P = 0.01). There were significant differences between groups in MIP and MEP at the end of the study in favour of the WBVTG. Conclusions WBVT provided significant improvements in functional capacity in severe COPD patients without changes in muscular force. [ABSTRACT FROM AUTHOR]

Objective To identify prognosis factors that allow us to identify patients at risk of developing chronic symptoms and disabilities after a whiplash injury. Participants 1436 patients who received a whiplash injury after a road traffic accident and met the Department of Physical Medicine and Rehabilitation for medical evaluation and rehabilitation treatment.
