OBJECTIVE: Chronic lateral epicondylosis is common, debilitating, and often refractory. Prolotherapy (PrT) is an injection therapy for tendinopathy. The efficacy of two PrT solutions for chronic lateral epicondylosis was evaluated. DESIGN: This study is a three-arm randomized controlled trial. Twenty-six adults (32 elbows) with chronic lateral epicondylosis for 3 mos or longer were randomized to ultrasound-guided PrT with dextrose solution, ultrasound-guided PrT with dextrose-morrhuate sodium solution, or watchful waiting ("wait and see").

Eighty-six patients with cervicogenic headaches underwent a comprehensive clinical and instrumental studies involving neurological and neuroorthopedic examinations; pain rating by the visual-analogue scale (VAS) and the rank scale, and neuroimaging and electrophysiologic techniques. The patients were divided into two groups: a study group (n = 43) and a control one (n = 43).

OBJECTIVE: To determine the effects of cervical contralateral rotation and cervical contralateral lateral flexion on vertebral artery blood flow velocity. DESIGN AND SETTING: A prospective study was performed at a private chiropractic clinic. PATIENTS: One hundred forty-eight patients had their vertebral arteries insonated as part of the premanipulative screening procedure.

BACKGROUND: Several studies have been published on the effect of cervical rotation alone upon blood flow in the vertebral arteries. However, we have not found articles addressing the question of how spinal manipulative therapy per se affects the vertebral artery flow. OBJECTIVE: The aim of the present study was to investigate whether any changes occur in peak flow velocity in the vertebral artery after spinal manipulative therapy as measured using the latest Doppler ultrasound technology.

The purpose of this study was to test the validity of Doppler ultrasound (US) velocimeter examination of vertebral arteries during contralateral (to the opposite side) cervical rotation. Vertebral arteries from 20 subjects were insonated using a bidirectional Doppler velocimeter at the suboccipital portal (standard technique) and C2 transverse process level (new technique) during contralateral cervical rotation. The results, regarding persistence or major reduction in Doppler signals, were then compared with those from a colour-flow duplex US scanner using the same procedure.

OBJECTIVE: To determine whether lumen narrowing in vertebral arteries during atlanto-axial rotation is due to stretch or localized compression. DESIGN AND SETTING: Experiments with models were made in a private chiropractic clinic, whereas studies of cadaveric specimens were performed in an anatomy laboratory. Doppler ultrasound and magnetic resonance angiography (MRA) studies were carried out in the radiology department of a public hospital. PATIENTS: Eight patients had their vertebral arteries examined by use of a Doppler velocimeter and MRA.

OBJECTIVE: It has been proposed that Doppler velocimetry, which is noninvasive, quick, and relatively inexpensive, should be used when the screening vertebral arteries before manipulation to reduce the risk of cervical manipulation-related injury to these vessels. The objective of this analysis of the literature is to study the evidence of the suitability of Doppler velocimetry for this purpose.

OBJECTIVE/HYPOTHESIS: Either licensed American chiropractors or traditional Chinese herbalists may produce vertiginous attack in a patient after cervical manipulation. The purpose of the study was to present our experience in treating these patients to determine the risk of this procedure. STUDY DESIGN: A retrospective study from May 1999 to April 2002.

OBJECTIVE: To determine whether the presence of posterior ponticles markedly increases by 30% or more, the incidence of major rotational stenosis of vertebral arteries. METHODS: Doppler ultrasound studies were performed in 3 private chiropractic clinics and in the radiology department of a public hospital, and magnetic resonance angiography (MRA) studies were made in the latter location. Thirty-two chiropractic patients had Doppler velocimetery, and 16 of these patients had MRA scanning.
