BACKGROUND CONTEXT In a small prospective study assessing 10 symptomatic and 10 asymptomatic subjects, Schellhas et al. compared cervical discography to magnetic resonance imaging. Within that study he reported on the distribution of pain for the C3-C4 to C6-C7 levels. Four years later, Grubb and Ellis reported retrospective data from his 12-year experience using cervical discography from C2-C3...

Low back pain is the most common pain symptom experienced by American adults and is the second most common reason for primary care physician visits. There are many structures in the lumbar spine that can serve as pain generators and often the etiology of low back pain is multifactorial. However, the facet joint has been increasingly recognized as an important cause of low back pain. Facet joint...

To assess the value of the provocative tests of glaucoma we investigated the water-drinking and jugular compression tests in about 140 eyes. Three groups of cases were investigated: (i) Normal eyes ... ... ... 50 (ii) Eyes with established glaucoma: (a) chronic simple glaucoma ... ... 33 (b) acute congestive glaucoma ... ... ... 13 57 (c) chronic congestive glaucoma ... ... 1 I J (iii) Pre-glau...

The currently advocated pre-manipulative risk assessment protocols include the use of provocative positional tests to challenge the integrity of the vascular supply to the brain. This paper examines the validity of these pre-manipulative provocative tests in light of recent studies involving ultrasound scanning of the vertebral arteries in subjects who also had provocative tests performed. Thes...

Asthma is usually diagnosed clinically. This study investigated how methacholine challenge and peak expiratory flow monitoring influenced change from a pretest clinical diagnosis. Records of 132 patients referred with respiratory symptoms, who subsequently had reliable measurements of both airway responsiveness (provocative concentration of methacholine causing a 20% fall in forced expiratory v...

Although coronary artery spasm is diagnosed by angiography using provocative drugs like Acetylcholine and Ergonovine, an exercise test following hyperventilation is an equivalent non-invasive test to diagnose this condition [2]. Thus, a negative provocative stress test ruled out the possibility of vasospastic angina in this patient. The Naranjo probability score confirmed an adverse drug reacti...

BACKGROUND This study was aimed at assessing the accuracy of provocative tests in diagnosis of acute or chronic Cervical Radiculopathy (CR) based on an electrodiagnostic reference criterion. MATERIALS AND METHODS Shoulder Abduction Test (SAT), Spurling Test (ST), Upper Limb Tension Test (ULTT), and electromyography were done on 97 patients who referred to Electrodiagnostic center in the unive...
