Three-point cyclic bending was applied to intervertebral joint complexes (three vertebrae with two intervertebral discs) of monkey (Macaca fascicularis), wallaby (Wallabia rufogrisea frutica), tiger (Panthera tigris), jaguar (Panthera onca) and seal (Halichoerus grypus). Force-displacement loops were recorded for intact specimens in both extension and(More)
OBJECTIVE To test systematically if spinal manipulative treatments (SMT) and the audible release associated with SMT cause activation of spinal muscles. DESIGN Experimental pilot study. SETTING Human Performance Laboratory, The University of Calgary. PARTICIPANTS One male and one female asymptomatic volunteer. INTERVENTION Slow and fast SMTs to the(More)
OBJECTIVE The purpose of this study was to compare the relative movements between adjacent vertebrae that were accompanied by a cavitation sound to those relative movements wherein no cavitation sound was recorded, during spinal manipulative treatments (SMTs) to T12 of an unembalmed human cadaver. SETTING The experiment was conducted in the gross anatomy(More)

Four-point bending was used to apply pure extension and flexion moments to the ligamentous lumbosacral spine and pelvic girdle of monkey (Macaca fascicularis), rabbit (domestic and wild, Oryctolagus cuniculus), badger (Meles meles), wallaby (Wallabia rufogrisea frutica), sheep (Ovis aries), seal (Phoca vitulina) and tiger (Panthera tigris). The absolute(More)
OBJECTIVE The purpose of this study was to measure the relative movements of vertebrae during manipulative thrusts to unembalmed post-rigor mortis human cadavers. SETTING The investigation was conducted in the gross anatomy laboratory at the University of Calgary. SUBJECTS Two 77-yr-old, unembalmed, post-rigor mortis, male cadavers were used. (More)
The aim of this study was to investigate whether the ligamentous lumbar vertebral column of a macaque could potentially provide passive mechanical support to the weight of the head, upper body and forelimbs during upright sitting. The seated flexed curvature of the lumbar spine of Macaca sylvana was estimated from a photograph and was partitioned equally(More)
The purpose of this study was to investigate the influence of training with heavy rugby balls on selected spin pass variables in youth rugby union players. Pre-training, 14 participants performed rapid spin passes (using right and left hands) at a wall-mounted target, from 7-m and 10-m distances. Horizontal (linear) and spin (longitudinal angular)(More)
