BACKGROUND The tissue origin of low back pain (LBP) or referred lower extremity symptoms (LES) may be identified in about 70% of cases using advanced imaging, discography and facet or sacroiliac joint blocks. These techniques are invasive and availability varies. A clinical examination is non-invasive and widely available but its validity is questioned.(More)
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(More)
The frequency, incidence and severity of low back pain was assessed by a random telephone survey of 314 urban New Zealanders. Relationships between the severity and frequency of low back pain and referred lower extremity pain and other variables such as occupation, recreation, age, sex and predominant working posture was analysed. Point incidence was 17.5%,(More)

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(More)
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(More)
BACKGROUND Only controlled blocks are capable of confirming the zygapophysial joints (ZJ) as the pain generator in LBP patients. However, previous workers have found that a cluster of clinical signs ("Revel's criteria"), may be valuable in predicting the results of an initial screening ZJ block. It was suggested that these clinical findings are unsuitable(More)
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(More)
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(More)
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(More)
BACKGROUND The diagnosis of subacromial pathology is limited by the poor accuracy of clinical tests for specific pathologies. The aim of this study was to estimate the diagnostic accuracy of clinical examination and imaging features for identifying subacromial pain (SAP) defined by a positive response to diagnostic injection, and to evaluate the influence(More)
