OBJECTIVE The study's objective was to examine the effect of body position on oxygen consumption (Vo(2)) and hemodynamics. Although gravity-dependent hemodynamic and pulmonary consequences are well documented, less is known about the effect of body positions on VO(2) and hemodynamics, which is of importance in critical care. DESIGN This was a(More)
This randomized controlled trial examined the psychological, physical, and neurophysiological effects of a qigong exercise program on depressed elders with chronic medical illness. The experimental group (n = 21, 80 ± 7 years) was given a 12-week qigong exercise program, while the comparison group (n = 17, 81 ± 8 years) participated in a newspaper reading(More)
OBJECTIVE The evidence of tai chi for balance improvement and fall reduction in older adults was updated and reviewed. METHOD A systematic review was carried out by two independent reviewers among nine electronic databases to identify randomized controlled trials (RCTs) that examined the effects of tai chi on balance improvement and fall reduction in(More)
BACKGROUND AND PURPOSE The oxygen demand of breathing exercises and the clinical implications have not been studied in detail. In this study, the oxygen cost of 3 common breathing exercises believed to reduce oxygen cost (ie, work of breathing) was compared with that of spontaneous breathing in patients with chronic obstructive pulmonary disease (COPD).

BACKGROUND Cardiopulmonary resuscitation is often performed in compromised conditions and for long periods. OBJECTIVE To compare energy expenditure, compression effectiveness, and kinetics of the spine during simulated chest compression with the rescuer in different positions. METHODS A 3-group design with 36 nurses (26 females) and 20 male emergency(More)
Transcutaneous Electrical Nerve Stimulation over acupoints (Acu-TENS) facilitates recovery of resting heart rate after treadmill exercise in healthy subjects. Its effect on postexercise respiratory indices has not been reported. This study investigates the effect of Acu-TENS on forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in(More)
OBJECTIVE Cardiopulmonary resuscitation (CPR) is frequently performed by allied health professionals, and, if undertaken in compromised positions, it may induce injury to the rescuer's spine. Back pain as an occupational symptom in manual workers has received considerable attention in the medical literature, but there is no report on the effect of CPR on(More)
Ventilator-associated pneumonia results from bacterial colonisation of the aerodigestive tract or aspiration of contaminated secretions into the lower airways. As a consequence of infection of the lung parenchyma and alveolitis, accumulation of inflammatory exudates and infiltration of airway mucosa can lead to unfavourable respiratory mechanics in(More)
CONTEXT The initial gain from a Pulmonary Rehabilitation Program (PRP) among patients with chronic obstructive pulmonary disease (COPD) begins to fade away 6 months after the completion of a rehabilitation program. One possible reason may be due to the poor compliance of the patients to the existing forms of home exercise program (e.g., walking, weight(More)
