OBJECTIVE: Muscle variants are common findings in dissection laboratories. These anomalous structures can be relevant in the diagnosis and management of certain conditions and therefore could be incorporated into anatomy curricula at chiropractic colleges. We aimed to create an online resource of muscle variants to facilitate student self-directed learning within this area of study. METHODS: At the time of their discovery during routine educational dissection, muscle variants included in the catalog were documented and subsequent case reports written...

Objective : The purpose of this study was to examine predictors for success on Parts I and II of the National Board of Chiropractic Examiners (NBCE) written examinations. Methods : Two validity studies were conducted to examine the criterion validity of Logan College assessments for Part I and II NBCE scores. Both studies consisted of a longitudinal design to examine the validity of entrance grade point average (GPA), in-program chiropractic course content GPA, and an institutional practice exam on Parts I and II of the NBCE...

OBJECTIVE: To measure changes in the quadriceps femoris angle (Q-angle) after the insertion of full-length flexible orthotics. SETTING: Outpatient health center of Logan College of Chiropractic. SUBJECTS: A total of 40 male subjects were included in the study population. The selected population all demonstrated bilateral pes planus or hyperpronation syndrome. DESIGN: Before-after trial. METHOD: A cohort demonstrating bilateral hyperpronation was recruited...

BACKGROUND AND OBJECTIVES: Since the founding of the chiropractic profession, very few efforts have been made to thoroughly explain the mechanism(s) by which joint complex dysfunction generates symptoms. Save for a few papers, only vague and physiologically inconsistent descriptions have been offered. The purpose of this article is to propose a precise and physiologically sound mechanism by which symptoms may be generated by joint complex dysfunction. DATA SOURCES: The data was accumulated over a period of years by reviewing contemporary articles and books, and subsequently retrieving relevant papers...

OBJECTIVE: To examine the rationale for and necessity of adjusting the film focal distance when X-ray angulation is employed during a radiographic study, and to determine the sensitivity of human interpreters to overall differences in film density and the correlation, if any, with digital analysis of radiographic films. DESIGN AND SETTING: The study was performed in the radiology department at Logan College of Chiropractic in St. Louis, Missouri. A standard X-ray phantom of the hand and wrist and several aluminum step wedges were exposed from 10% to 250% of baseline exposure intensity using equipment commonly found in a field doctor's practice...

OBJECTIVE: Little attention has been given to the craniovertebral articulations. Specifically, gross observations of variations of the superior articular facets on the atlas have not been described with respect to static and motion palpation findings. This study describes the anatomical variations of these facets and the clinical implications associated with asymmetrical structure. DESIGN: The superior articular facets of thirty human first cervical vertebrae were chosen for this study because the atlas constitutes the middle of the upper cervical complex and the atlanto-occipital joint contributes greatly to head movements...
