Surgical trials excluded from this review were almost exclusively conducted on patients with specific pathology, usually a demonstrated neurological compromise. We found no controlled trials that investigated the use of procedures such as fusion or disc

replacement for non-specific neck complaints. Given the high potential for serious adverse events and the high costs associated with surgery there is a need to establish better knowledge about the outcome of these procedures. Despite the extensive evidence identified and summarised by this review, several questions have not been answered comprehensively. ZD1839 Although we identified 221 studies that investigated interventions for neck pain, only 33 trials met our criteria of having participants with clearly defined nonspecific neck pain, and using a placebo, sham, or minimal or no intervention as a control. There is a need for greater consistency in classification of neck pain and conditions associated with neck pain. We excluded a large number of trials in which two active interventions were compared, ie, without comparison to a placebo, sham, or minimal or no intervention. This type of comparative trial should be a lower research priority in making determinations about efficacy. This review has identified evidence supporting some interventions for non-specific neck pain. However, none of these selleck compound interventions

was shown to have lasting benefit. There is a need to establish whether simple and inexpensive measures such as reassurance, self-care advice, and simple analgesics provided

by trained practitioners are effective for neck pain. first Future research might focus on the question of whether the addition of commonly provided or novel interventions confers additional benefits to quality baseline care. This is particularly pertinent for interventions that involve exposure to additional risks or incur additional costs. eAddenda: Appendix 1, Tables 3 to 6 available at jop. physiotherapy.asn.au Support: AL was funded by a University of Sydney scholarship.

“Both the prevalence and incidence of chronic heart failure have increased due to the improved survival of coronary heart disease patients and to the aging of populations worldwide (Bleumink et al 2004). The major symptoms of chronic heart failure include exertional dyspnoea, fatigue, exercise intolerance, and functional limitations, which may result in poor quality of life. Previous studies suggested that both central and peripheral impairments limit exercise capacity in chronic heart failure patients (Mueller et al 2007, van Tol et al 2006, Volaklis and Tokmakidis, 2005). Aerobic exercise training has been considered a safe and effective strategy to improve clinical symptoms (Flynn et al 2009, Mueller et al 2007, O’Connor et al 2009).
