Objective To update our previously published systematic review and meta-analysis by subjecting the literature on shoulder physical examination (ShPE) to careful analysis in order to determine each tests clinical utility. Methods This review is an update of previous work, therefore the terms in the Medline and CINAHL search strategies remained the same with the exception that the search was confi ned to the dates November, 2006 through to February, 2012. The previous study dates were 1966 -October, 2006. Further, the original search was expanded, without date restrictions, to include two new databases: EMBASE and the Cochrane Library. The Quality Assessment of Diagnostic Accuracy Studies, version 2 (QUADAS 2) tool was used to critique the quality of each new paper. Where appropriate, data from the prior review and this review were combined to perform meta-analysis using the updated hierarchical summary receiver operating characteristic and bivariate models. Results Since the publication of the 2008 review, 32 additional studies were identifi ed and critiqued. For subacromial impingement, the meta-analysis revealed that the pooled sensitivity and specifi city for the Neer test was 72% and 60%, respectively, for the HawkinsKennedy test was 79% and 59%, respectively, and for the painful arc was 53% and 76%, respectively. Also from the meta-analysis, regarding superior labral anterior to posterior (SLAP) tears, the test with the best sensitivity (52%) was the relocation test; the test with the best specifi city (95%) was Yergason's test; and the test with the best positive likelihood ratio (2.81) was the compression-rotation test. Regarding new (to this series of reviews) ShPE tests, where meta-analysis was not possible because of lack of suffi cient studies or heterogeneity between studies, there are some individual tests that warrant further investigation. A highly specifi c test (specifi city >80%, LR+ ≥ 5.0) from a low bias study is the passive distraction test for a SLAP lesion. This test may rule in a SLAP lesion when positive. A sensitive test (sensitivity >80%, LR− ≤ 0.20) of note is the shoulder shrug sign, for stiffnessrelated disorders (osteoarthritis and adhesive capsulitis) as well as rotator cuff tendinopathy. There are six additional tests with higher sensitivities, specifi cities, or both but caution is urged since all of these tests have been studied only once and more than one ShPE test (ie, active compression, biceps load II) has been introduced with great diagnostic statistics only to have further research fail to replicate the results of the original authors. The belly-off and modifi ed belly press tests for subscapularis tendinopathy, bony apprehension test for bony instability, olecranon-manubrium percussion test for bony abnormality, passive compression for a SLAP lesion, and the lateral Jobe test for rotator cuff tear give reason for optimism since they demonstrated both high sensitivities and specifi cities reported in low bias studies. Finally, one additional test was studied in tw...
For rehabilitation professionals engaged in the treatment of osteoarthritis (OA), it is standard practice to perform objective assessments of physical function (using both physical performance and self-report measures) to obtain a picture of patient status. These assessments also serve as a baseline value for estimating changes (treatment effects) over time. While reliability and validity of some commonly used physical performance measures have been investigated in an OA population, most require further research regarding clinical utility and responsiveness. 14 Physical performance measures have often been criticized, as detailed testing of their measurement properties has not been extensively reported. 14,22,33 Measures of responsiveness have commonly been reported as statistically significant change scores, which are useful in establishing the threshold of change needed beyond measurement error. 10 Investigation of minimal clinically important differences (MCIDs) of physical performance measures is warranted, as these have become commonly used outcome measures in the treatment of OA. 8,12,17,[35][36][37] At present, the responsiveness (in terms of MCID) of the timed up-and-go (TUG) test, 40-meter self-paced walk test (40-m SPWT), 30-second chair stand (30 CST), and 20-cm step test has not been investigated in T T STUDY DESIGN: Prospective cohort study. T T OBJECTIVES:To establish the major clinically important improvement (MCII) of the timed upand-go test (TUG), 40-meter self-paced walk test (40-m SPWT), 30-second chair stand (30 CST), and a 20-cm step test in patients with hip osteoarthritis (OA) undergoing physiotherapy treatment. As a secondary aim, a comparison of methods was employed to evaluate the effect of method on the reported MCII. T T BACKGROUND: Minimal clinically importantdifference scores are commonly used by rehabilitation professionals to determine patient response following treatment. A gold standard for calculating MCII has yet to be determined, which has resulted in problems of interpretation due to varied results. T T METHODS:As part of a randomized controlled trial, 65 patients were randomized into a physiotherapy treatment group for hip OA, in which they completed 4 physical performance measures at baseline and 9 weeks. Upon completion of physiotherapy, patients assessed their response to treatment on a 15-point global rating of change scale (GRCS). MCII was estimated using 3 variations of an anchor-based method, based on the patient's opinion. T T RESULTS:A comparison of 3 methods resulted in the following change scores being best associated with our definition of MCII: a reduction equal to or greater than 0.8, 1.4, and 1.2 seconds for the TUG; an increase equal to or greater than 0.2, 0.3, and 0.2 m/s for the 40-m SPWT; an increase equal to or greater than 2.0, 2.6, and 2.1 repetitions for the 30 CST; an increase equal to or greater than 5.0, 12.8, and 16.4 steps for the 20-cm step test. T T CONCLUSION:The variation in methods provided very different results. This illustrates the impor...
Considerable variability exists in the demands of straight-line running and multi-directional demands across sports, competition levels, and sexes, indicating the need for sports medicine clinicians to design future rehabilitation programs with improved specificity (including the type of activity and dosage) to these demands.

MRI was identified as the most sensitive and specific imaging test for diagnosing stress fractures of the lower extremity. When MRI is available, NS is not recommended because of its low specificity, high dosage of ionizing radiation, and other limitations. Conventional radiographs are likely to result in false negatives upon initial presentation, particularly in the early stages of stress fracture, and in some cases may not reveal an existing stress fracture at any time. A diagnostic imaging algorithm was developed with specific recommendations for cost-efficient imaging of low-risk and high-risk suspected stress fractures.
BackgroundHip Physical Examination (HPE) tests have long been used to diagnose a myriad of intra-and extra-articular pathologies of the hip joint. Useful clinical utility is necessary to support diagnostic imaging and subsequent surgical decision making.ObjectiveSummarise and evaluate the current research and utility on the diagnostic accuracy of HPE tests for the hip joint germane to sports related injuries and pathology.MethodsA computer-assisted literature search of MEDLINE, CINHAL and EMBASE databases (January 1966 to January 2012) using keywords related to diagnostic accuracy of the hip joint. This systematic review with meta-analysis utilised thePreferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) guidelines for the search and reporting phases of the study. Der-Simonian and Laird random effects models were used to summarise sensitivities (SN), specificities (SP), likelihood ratios and diagnostic OR.ResultsThe employed search strategy revealed 25 potential articles, with 10 demonstrating high quality. Fourteen articles qualified for meta-analysis. The meta-analysis demonstrated that most tests possess weak diagnostic properties with the exception of the patellar-pubic percussion test, which had excellent pooled SN 95 (95% CI 92 to 97%) and good specificity 86 (95% CI 78 to 92%).ConclusionSeveral studies have investigated pathology in the hip. Few of the current studies are of substantial quality to dictate clinical decision-making. Currently, only the patellar-pubic percussion test is supported by the data as a stand-alone HPE test. Further studies involving high quality designs are needed to fully assess the value of HPE tests for patients with intra- and extra-articular hip dysfunction.
A majority of the identified risk factors associated with first time sciatica are modifiable, suggesting the potential benefits of primary prevention. In addition, those risk factors are also associated with unhealthy lifestyles, which may function concomitantly toward the development of sciatica. Sciatica as a diagnosis is inconsistently defined among studies.
