The Purpose of this Study was to investigate whether a manipulation to the L3/4 motion segment of healthy individuals would affect the strength of the quadriceps muscle tested postmanipulation. Fifteen consenting experimental subjects received a lumbar roll manipulation and 15 nonexperimental subjects underwent a simulated manipulation in the lumbar roll position. After these procedures, all…
Objective: To examine the relationship between bed hardness and muscle activity during sleep. Design: All subjects sleep on mattresses of varying hardness. Mattress hardness is determined by the Australian Spinal Research Foundation rating protocol on a one to five scale. The beds used are designated as soft, medium and firm. Each subject will sleep three…
Purpose: To determine the most commonly used diagnostic methods for detecting the spinal entity that chiropractors adjust/manipulate and the preferred term for describing this entity. Design: Postal survey (self-completed questionnaire). Setting: Victoria, Australia. Participants: All 554 chiropractors registered May 30, 1994, with the Chiropractors and Osteopaths Registration Board of Victoria. Main outcome measures: Frequency of…
The history of chiropractic in Australia is traced from the first grateful patient who also attended a course of instruction at the Palmer School and Infirmary of Chiropractic under D.D. Palmer and B.J. Palmer and brought chiropractic to Australia. The influence of Henry Otterholt–a U.S.-born Palmer graduate who was recruited by an untrained manipulator to…
Objectives: To (i) measure lumbar intervertebral motion patterns produced during low force, high frequency posteroanterior (PA) thrusts applied to adjacent thoracolumbar spinal segments; (ii) determine the dependence of PA stiffness and impedance characteristics of the thoracolumbar spine on loading frequency; and (iii) ascertain the feasibility of using PA stiffness or impedance to characterize the in vivo…
Objective: To determine the prevalence of indigestion and mid-back pain in persons seeking chiropractic care. Design: A cross-sectional survey using a self-report questionnaire. Setting: Three primary care private chiropractic practices in metropolitan Perth, Australia. Subjects: Persons seeking chiropractic care during a 1-month period. Intervention: None. Outcome measures: Six-month prevalence of indigestion and mid-back pain, rate of association between indigestion and mid-back…
Objective: As part of a randomised clinical trial to determine the efficacy of chiropractic therapy on premenstrual syndrome (PMS), subjects were evaluated for initial underlying spinal dysfunction. Subjects: Fifty-four subjects with diagnosed PMS (using a Moos PMS questionnaire plus daily symptom monitoring) and 30 subjects with no diagnosable PMS were recruited by newspaper advertising and…
Summary of aim(s): To demonstrate the terminal afferents from the thoracic spine, particularly from TI to T4 intra articular tissues. To demonstrate the types of different afferent projections, from a typical thoracic spinal joint. To demonstrate the distribution of those afferents within the Rexed laminae. Findings / Outcomes: A study was undertaken to investigate the…
Dysfunction of the cervical vertebral column may produce headaches and cause disturbances to balance and posture. It is also known that there is a high density of sensory receptors in the paravertebral musculature in the neck. However, little is known about how afferent nerves from the vertebral column and its associated ligaments influence the central…
The effects of sacro-iliac joint dysfunction on walking will be explored using five normal individuals and ten with sacro-iliac joint dysfunction. The subjects will be filmed at the University of New South Wales Ergonomics Iab. Five of those with sacro-iliac joint pain will be filmed before chiropractic adjustment, immediately after adjustment and after one week…
