OBJECTIVE The objective of this pilot study was to determine the number of patients required for a randomized controlled trial of spinal manipulation for neck pain and to determine if there is a relationship between pain and range of motion (ROM) in the cervical spine. DESIGN Fifty consecutive outpatients were studied in a pretest-posttest design without(More)
BACKGROUND Prognosis of whiplash injury has been found to be related to a number of sociodemographic, treatment and clinical factors. In the current study, we attempt to identify several novel prognostic factors for delayed recovery in whiplash-associated disorders (WADs), using a validated and reliable measure of recovery. PATIENTS AND METHODS(More)
STUDY DESIGN Retrospective clinical cohort study. OBJECTIVE To identify the prognostic factors associated with a poor response to treatment in the early stages of a whiplash-associated disorder (WAD). SUMMARY OF BACKGROUND DATA Several demographic and clinical factors related to recovery following acute WADs have been identified. However, few(More)
BACKGROUND CONTEXT Evidence-based clinical practice guidelines (CPGs) for the management of patients with acute mechanical low back pain (AM-LBP) have been defined on an international scale. Multicenter clinical trials have demonstrated that most AM-LBP patients do not receive CPG-based treatments. To date, the value of implementing full and exclusively(More)
We describe the case of a patient with a lumbar disc herniation who underwent a course of side posture manipulation. Despite the appearance of an enormous central herniation on the CT scan, the patient improved considerable during only 2 wk of treatment. The disparity which so commonly exists between radiological and clinical findings is depicted in this(More)
BACKGROUND Despite available evidence for optimal management of spinal pain, poor adherence to guidelines and wide variations in healthcare services persist. One of the objectives of the Canadian Chiropractic Guideline Initiative is to develop and evaluate targeted theory- and evidence-informed interventions to improve the management of non-specific neck(More)
BACKGROUND CONTEXT Waitlists are commonly used in Canada to manage access to surgical procedures such as elective surgical lumbar discectomy (ESLD). The timing of enrollment onto the waitlist is important as this is a proxy measure for the concordance of preferences for surgery between a patient and surgeon. After enrollment, the waiting time to actual(More)
Joint "cracking" is common but not a clearly understood audible phenomenon. In this brief report we propose an in-vitro model to potentially assist in revealing a mechanism for, and therefore source of, this phenomenon. Using a suction cup under tension and de-nucleated fluid to simulate synovial fluid, an audible release with intra-articular cavity(More)
STUDY DESIGN Prospective cohort study of patients registered for elective surgical lumbar discectomy (ESLD) between November 1999 and December 2003 at a major tertiary care center in Vancouver. OBJECTIVE To determine whether compensation status was associated with longer waiting time for ESLD. SUMMARY OF BACKGROUND DATA In Canada, access to publicly(More)
