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 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)
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 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)
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)
The voltage dependent ionic conductances were studied by analysing the phase plane trajectories of action potentials evoked by electrical stimulation of the sartorius muscles of the frog (Rana esculenta). The delayed outward potassium current was measured also under voltage clamp conditions on muscle fibres of either the frog (Rana esculenta) or Xenopus(More)
