Question Are there differences in the effectiveness of pelvic floor muscle training on pelvic floor muscle strength and urinary incontinence symptoms in postmenopausal women who are and are not using hormone therapy? Design Randomised, controlled trial with concealed allocation, blinded assessors, and intention-to-treat analysis. Participants Ninety-nine postmenopausal women, 38 of whom were using daily systemic oestrogen/progestogen therapy. Intervention The experimental group (n = 51) received an intensive supervised pelvic floor muscle training protocol, and the control group (n = 48) received no intervention. The randomisation was stratified by hormone therapy use. Outcome measures Change in pelvic floor muscle strength assessed with manometry at 12 weeks. Prevalence and severity of urinary incontinence symptoms were assessed using questionnaires. Results Eighty-eight women provided data that could be included in the analysis. Pelvic floor muscle training increased pelvic floor muscle strength by 8.0 cmH 2 O (95% CI 3.4 to 12.6) in women not using hormone therapy and by –0.9 cmH 2 0 (95% CI –6.5 to 4.8) in women using hormone therapy (interaction p = 0.018). A sensitivity analysis showed that the greater training effect in women who were not using hormone therapy was still apparent if the analysis was conducted on percentage change in strength rather than absolute change in strength. There was also a significantly greater effect of training in women not using hormone therapy on prevalence of urinary incontinence symptoms (ratio of odds ratios = 7.4; interaction p = 0.028). The difference in effects on severity of urinary incontinence symptoms was not statistically significant (interaction p = 0.37). Conclusion Pelvic floor muscle training increases pelvic floor muscle strength more in women who are not using hormone therapy than in women using hormone therapy.

Question Is stretch effective for the treatment and prevention of contractures in people with neurological and non-neurological conditions? Design A Cochrane Systematic Review with meta-analyses of randomised trials. Participants People with or at risk of contractures. Intervention Trials were considered for inclusion if they compared stretch to no stretch, or stretch plus co-intervention to co-intervention only. The stretch could be administered in any way. Outcome measures The outcome of interest was joint mobility. Two sets of meta-analyses were conducted with a random-effects model: one for people with neurological conditions and the other for people with non-neurological conditions. The quality of evidence supporting the results of the two sets of meta-analyses was assessed using GRADE. Results Eighteen studies involving 549 participants examined the effectiveness of stretch in people with neurological conditions, and provided useable data. The pooled mean difference was 2 deg (95% CI 0 to 3) favouring stretch. This was equivalent to a relative change of 2% (95% CI 0 to 3). Eighteen studies involving 865 participants examined the effectiveness of stretch in people with non-neurological conditions, and provided useable data. The pooled standardised mean difference was 0.2 SD (95% CI 0 to 0.3) favouring stretch. This translated to an absolute mean increase of 1 deg (95% CI 0 to 2) and a relative change of 1% (95% CI 0 to 2). The GRADE level of evidence was high for both sets of meta-analyses. Conclusion Stretch does not have clinically important effects on joint mobility.

Question: What is the effect of a multifactorial intervention on frailty and mobility in frail older people who comply with their allocated treatment? Design: Secondary analysis of a randomised, controlled trial to derive an estimate of complier average causal effect (CACE) of treatment. Participants: A total of 241 frail community-dwelling people aged ≥ 70 years. Intervention: Intervention participants received a 12-month multidisciplinary intervention targeting frailty, with home exercise as an important component. Control participants received usual care. Outcome measures: Primary outcomes were frailty, assessed using the Cardiovascular Health Study criteria (range 0 to 5 criteria), and mobility measured using the 12-point Short Physical Performance Battery. Outcomes were assessed 12 months after randomisation. The treating physiotherapist evaluated the amount of treatment received on a 5-point scale. Results: 216 participants (90%) completed the study. The median amount of treatment received was 25 to 50% (range 0 to 100). The CACE (ie, the effect of treatment in participants compliant with allocation) was to reduce frailty by 1.0 frailty criterion (95% CI 0.4 to 1.5) and increase mobility by 3.2 points (95% CI 1.8 to 4.6) at 12 months. The mean CACE was substantially larger than the intention-to-treat effect, which was to reduce frailty by 0.4 frailty criteria (95% CI 0.1 to 0.7) and increase mobility by 1.4 points (95% CI 0.8 to 2.1) at 12 months. Conclusion: Overall, compliance was low in this group of frail people. The effect of the treatment on participants who comply with allocated treatment was substantially greater than the effect of allocation on all trial participants.

The article explores the database of diagnostic test accuracy studies for physiotherapists. Topics discussed include cardiorespiratory physiotherapy arises when a physiotherapist aims to confirm the presence or absence of chronic obstructive pulmonary disease; of diagnostic test accuracy and systematic reviews of primary studies of diagnostic test accuracy; and controlled trials of diagnostic tests provide estimates of the accuracy of tests.

• First head-to-head comparison of QUADAS, QUADAS-2, DAQS measurement properties. • Inter-tester reliability of individual items of the tools was poor. • Summary scores were imprecise and convergent validity was often low. • The quality of the included studies was mixed. • A new quality assessment tool should exclude items relating to generalizability. To determine the reliability, internal consistency, measurement error, convergent validity, and floor and ceiling effects of three quality assessment tools commonly used to evaluate the quality of diagnostic test accuracy studies in physical therapy. A secondary aim was to describe the quality of a sample of diagnostic accuracy studies. 50 studies were randomly selected from a comprehensive database of physical therapy-relevant diagnostic accuracy studies. Two reviewers independently rated each study with the Quality Assessment of Diagnostic Accuracy Studies (QUADAS), Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) and Diagnostic Accuracy Quality Scale (DAQS) tools in random sequence. Only 7% of QUADAS items, 14% of QUADAS-2 items, and 33% of DAQS items had at least moderate inter-rater reliability (kappa > 0.40). Internal consistency and convergent validity measures were acceptable (>0.70) in 33% and 50% of cases respectively. Floor or ceiling effects were not present in any tool. The quality of studies was mixed: most avoided case–control sampling strategies and used the same reference standard on all subjects, but many failed to enroll a consecutive or random sample of subjects or provide confidence intervals about estimates of diagnostic accuracy. The QUADAS, QUADAS-2 and DAQS tools provide unreliable estimates of the quality of studies of diagnostic accuracy in physical therapy. [ABSTRACT FROM AUTHOR]
