Improving physical activity in patients with COPD with urban walking circuits.

BACKGROUND: Even after a rehabilitation program, levels of physical activity in COPD progressively decrease unless strategies to encourage activity are implemented. We analyzed the effects of the implementation of urban walking circuits on levels of physical activity and exercise capacity of patients with severe and very severe COPD after a rehabilitation program. METHOD: A total of 83 patients were randomized to either urban circuits group (UCG) or usual care in the non-circuit group (NCG), after completing a 2-week rehabilitation program. Results were evaluated 9 months after completion of the rehabilitation program and were compared with a control group of 54 patients not enrolled in the rehabilitation program. RESULTS: At the end of follow-up, UCG patients increased their physical activity by a mean of 32.4 (SE = 5.9) min per day and 1.09 (SE = 0.22) days walked per week; 33.9 (SE = 5.6) min per day and 1.12 (SE = 0.24) days per week more compared to the NCG (p < 0.001). There was a significant positive correlation between the results of the 6-min walking test and minutes walked per day in the UCG (r(2) = 0.52, p < 0.05) but not in the NCG (r(2) = 0.094, p > 0.05). Controls showed a significant decrease in exercise capacity and physical activity over the follow-up. CONCLUSIONS: Urban circuits are an easy, inexpensive strategy, which demonstrated to be useful to stimulate physical activity in our population of severe and very severe COPD patients and resulted in increased exercise capacity even 9 months after completion of a rehabilitation program.

Effects of whole body vibration training in patients with severe chronic obstructive pulmonary disease.

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.

[Factors related with clinical evolution in whiplash]. / Factores relacionados con la evolución clínica del síndrome del latigazo cervical.

BACKGROUND AND OBJECTIVE: Factors of poor clinical recovery in acute whiplash are not conclusive. The goal of this prospective longitudinal study was to identify factors with influence in clinical evolution allowing us to identify patients with risk for developing chronic symptoms and disabilities after an acute whiplash. PATIENTS AND METHOD: We included 226 patients who suffered acute whiplash after road traffic accident and met the Department of Physical Medicine and Rehabilitation for medical evaluation and physiotherapy treatment. We collected variables following a protocol designed for the study. All patients were assessed through the visual analogue scale (VAS) for the intensity of neck pain, the Goldberg Depression and Anxiety Scale and the Northwick Park Neck Pain Questionnaire (NPH) for cervical column functionality, at initial evaluation and at discharge of treatment. RESULTS: Factors related with poor recovery of NPH at discharge were: number of days of cervical column immobilization with collar, presence of headache, dizziness, and dorsal pain at initial evaluation and initial evaluation of VAS score and Goldberg Depression and Anxiety Scale. In the multivaried analysis we found that variables with influence on NPH at discharge were statistically significant for VAS, Goldberg depression subscale and NPH scores at initial evaluation. CONCLUSIONS: The most important factors that determine the evolution of patients with acute whiplash are the initial evaluation of the neck pain with the Visual Analogue Scale, the cervical column functionality with NPH and Goldberg Depression subscale.
