The type and location of the exercise may also influence the benefit obtained. These points BVD523 are important to consider in an elderly population, who may experience limitations in where and how they can exercise. The meta-analysis examined the combined results of different studies to increase the overall statistical power and the precision of estimates while controlling for bias and limiting random error. Nevertheless, several limitations in generalising the findings must be acknowledged. First, a relatively small number of trials, all of which included a relatively small sample size, were examined. Trials reported in languages other than English and Chinese were excluded, as were trials reported only as

abstracts. These exclusions may have led to publication bias. Also, more participants were female, making the observed effects less certain in men. A-1210477 manufacturer In summary, the results of this meta-analysis indicate that participation in exercise training has a moderately beneficial effect on sleep quality and decreases both sleep

latency and use of sleep medication. These findings suggest that physical exercise therapy could be an alternative or complementary approach to existing therapies for sleep problems, especially since exercise is low cost, widely available and generally safe. eAddenda: Figures 3, 5, 7, 9, 10, 11, 12, and 13 available at jop.physiotherapy.asn.au “
“Acute low back pain is defined as pain, increased muscle tonus, and stiffness localised below the costal margin and above the inferior gluteal folds, sometimes accompanied by radiating pain, for up to six weeks. Pain that continues but does not exceed 12 weeks is defined as subacute, becoming chronic thereafter (van Tulder et al 2002, Koes et al 2006). The lifetime prevalence of low back pain Parvulin is greater than 70% in industrialised countries (Airaksinen et al 2006). Several studies have reported that acute low back pain improves within four weeks, with 75–90% recovery and a relapse rate of 60% (Coste et al 2004, Grotle et al 2007). However, a small proportion of people

with acute low back pain progress to have chronic low back pain (Waddell et al 2003, Waddell et al 2004). Low back pain may cause a person to take sick leave or it may cause disability that limits a person’s ability to perform usual work activities. Either of these can contribute to the period absent from usual work. Recall of sick leave is accurate over 2 to 3 months and reliable (Burdorf et al 1996, Severens et al 2000, Frederiksson et al 1998). Some psychosocial factors measured in the acute or subacute stages of low back pain are predictors of progression, with the strength of the prediction being dependent on the time of measurement (Burton et al 2003). One psychosocial factor that we address in this review is the patient’s prediction or expectations, which we define as what patients believe might occur. These expectations may be a prognostic indicator, perhaps by affecting clinical outcomes.
