RANDOMIZED CONTROLLED TRIAL
Steven G White, Peter McNair, Mark Laslett, Wayne Hing
OBJECTIVE: To determine the reliability of patient reports of pain intensity during the application of physical tests. METHODS: A single examiner required participants to use the numeric pain rating scale (NPRS) to report the intensity of pain provoked during physical testing of the hip. Standardized versions of 14 physical tests were used on 18 people with hip pain. Tests were repeated at 1 hour and 2-7 days later. Within- and between-session reliability of reports of pain intensity was calculated using intraclass correlation coefficients (ICCs) and Lin's concordance correlation coefficients (CCCs)...

MULTICENTER STUDY
Angela Cadogan, Peter McNair, Mark Laslett, Wayne Hing
BACKGROUND: Despite numerous methodological flaws in previous study designs and the lack of validation in primary care populations, clinical tests for identifying acromioclavicular joint (ACJ) pain are widely utilised without concern for such issues. The aim of this study was to estimate the diagnostic accuracy of traditional ACJ tests and to compare their accuracy with other clinical examination features for identifying a predominant ACJ pain source in a primary care cohort. METHODS: Consecutive patients with shoulder pain were recruited prospectively from primary health care clinics...

COMPARATIVE STUDY
Mark Laslett, Peter McNair, Angela Cadogan, Wayne Hing
OBJECTIVES: Key diagnostic decisions often turn on measurement of change in pain intensity after diagnostic anesthetic blocks. This study aimed to introduce a new direct measure pain intensity change and compare it with percent change as calculated from the traditional preprocedure and postprocedure pain visual analog scales. METHODS: Shoulder pain patients enrolled in a diagnostic accuracy study comparing clinical variables with image-guided local anesthetic injections were assessed with both the traditional preprocedure and postprocedure visual analog scales and the new direct method...

PURPOSE: Over 20 years ago the term non-specific low back pain became popular to convey the limitations of our knowledge of the pathological source of most people's low back pain. Knowledge of underlying pathology has advanced little since then, despite limited improvements in outcomes for patients with low back pain. METHODS: This paper discusses potential misunderstandings related to diagnostic studies in the field of low back pain and argues that future diagnostic studies should include and investigate pathological sources of low back pain...

BACKGROUND: The prevalence of imaged pathology in primary care has received little attention and the relevance of identified pathology to symptoms remains unclear. This paper reports the prevalence of imaged pathology and the association between pathology and response to diagnostic blocks into the subacromial bursa (SAB), acromioclavicular joint (ACJ) and glenohumeral joint (GHJ). METHODS: Consecutive patients with shoulder pain recruited from primary care underwent standardised x-ray, diagnostic ultrasound scan and diagnostic injections of local anaesthetic into the SAB and ACJ...

Orthopaedic special tests (OST) are commonly used in the assessment of the painful shoulder to assist to rule-in or rule-out specific pathology. A small number of tests with high levels of diagnostic accuracy have been identified but interexaminer reliability data is variable or lacking. The aim of this study was to determine the interexaminer reliability of a group of OST with demonstrated diagnostic accuracy at primary care level. Forty consecutive subjects with shoulder pain were recruited. Six tests were performed by two examiners (physiotherapists) on the same day...

Acceptable reliability is a prerequisite for inclusion of physical examination tests in clinical examinations of the painful shoulder. The aim of this study was to establish the intraexaminer and interexaminer reliability of measures of shoulder range of motion (ROM) and muscle force using a new hand-held dynamometer with the ability to standardize overpressure force during passive ROM tests. Forty consecutive subjects with shoulder pain were recruited, and tests were performed by two physiotherapists. Tests included active ROM elevation, passive ROM glenohumeral abduction and external rotation and resisted abduction and external rotation...

BACKGROUND: Low-back pain with leg pain (sciatica) may be caused by a herniated intervertebral disc exerting pressure on the nerve root. Most patients will respond to conservative treatment, but in carefully selected patients, surgical discectomy may provide faster relief of symptoms. Primary care clinicians use patient history and physical examination to evaluate the likelihood of disc herniation and select patients for further imaging and possible surgery. OBJECTIVES: (1) To assess the performance of tests performed during physical examination (alone or in combination) to identify radiculopathy due to lower lumbar disc herniation in patients with low-back pain and sciatica;(2) To assess the influence of sources of heterogeneity on diagnostic performance...

Mark Laslett
The acute onset lumbar lateral shift, otherwise known as a list or acute scoliosis, is a common clinical observation associated with low back pain. In general orthopaedics, the presence of a lateral shift is associated with a poor prognosis; however, a manual correction method devised by McKenzie is claimed to produce rapid reversal of the deformity and reduction in pain. This single-case report presents the details of the McKenzie Mechanical Diagnosis and Treatment (MDT) management of a major right-sided lateral shift, which includes the manual correction technique, self-correction and management, prophylaxis, pain ablation, and rehabilitation to a high level of athletic function, with long-term follow-up at 9 months...

Surface marker expression forms the basis for characterization and isolation of human embryonic stem cells (hESCs). Currently, there are few well-defined protein epitopes that definitively mark hESCs. Here we combine immunotranscriptional profiling of hESC lines with membrane-polysome translation state array analysis (TSAA) to determine the full set of genes encoding potential hESC surface marker proteins. Three independently isolated hESC lines (HES2, H9, and MEL1) grown under feeder and feeder-free conditions were sorted into subpopulations by fluorescence-activated cell sorting based on coimmunoreactivity to the hESC surface markers GCTM-2 and CD9...

Mark Laslett
Sacroiliac joint (SIJ) pain refers to the pain arising from the SIJ joint structures. SIJ dysfunction generally refers to aberrant position or movement of SIJ structures that may or may not result in pain. This paper aims to clarify the difference between these clinical concepts and present current available evidence regarding diagnosis and treatment of SIJ disorders. Tests for SIJ dysfunction generally have poor inter-examiner reliability. A reference standard for SIJ dysfunction is not readily available, so validity of the tests for this disorder is unknown...

BACKGROUND: Only controlled intra-articular zygapophyseal joint (ZJ) injections or medial branch blocks can diagnose ZJ-mediated low back pain. The low prevalence of ZJ pain implies that identification of clinical predictors of a positive response to a screening block is needed. PURPOSE: To estimate the predictive power of clinical findings in relation to pain reduction after screening ZJ blocks. STUDY DESIGN: As part of a wider prospective blinded study investigating diagnostic accuracy of clinical variables, a secondary analysis was carried out to seek evidence of variables potentially valuable as predictors of screening ZJ block outcomes...

Discography is the only available method of directly challenging the discs for pain sensitivity. However, it is invasive, expensive and there is a debate about its clinical value. There is a need to identify clinical signs that may indicate the need for a discography examination. Pain centralization (retreat of referred pain to towards the spinal midline) has been associated with positive discography and possesses specificity between 80 and 100% depending on levels of disablement and psychosocial distress. Less than half of positive discography patients reports centralization and there is a need to identify other potentially valuable predictors...

Previous research indicates that physical examination cannot diagnose sacroiliac joint (SIJ) pathology. Earlier studies have not reported sensitivities and specificities of composites of provocation tests known to have acceptable inter-examiner reliability. This study examined the diagnostic power of pain provocation SIJ tests singly and in various combinations, in relation to an accepted criterion standard. In a blinded criterion-related validity design, 48 patients were examined by physiotherapists using pain provocation SIJ tests and received an injection of local anaesthetic into the SIJ...
