Rear-end impacts caused worse initial symptoms and specific clinical findings, not clearly distinguished from those occurring after frontal impacts. WAD III injuries, retro-orbital pain, and isolated contra-directional pro-/retraction pain occurred more frequently after rear-end impacts, indicating the importance of shear loads and craniocervical junction vulnerability. Head inward rotation dur...

The analytical Fourier-Mellin transform is used in order to assess motion parameters between gray-level objects having the same shape with distinct scale and orientation. From results on commutative harmonic analysis, a functional is constructed in which the location of the minimum gives an estimation of the size and orientation parameters. Furthermore, when the set of geometrical transformatio...

This study examined the effect of translatoric spinal manipulation (TSM) on cervical pain and cervical active motion restriction when applied to upper thoracic (T1-T4) segments. Active cervical rotation range of motion was measured re- and post-intervention with a cervical inclinometer (CROM), and cervical pain status was monitored before and after manipulation with a Faces Pain Scale. Study pa...

The phonon Raman spectra of crystals of dimethy~~tylene, pcrdeyrero-cjimetfiylacetylene and their n%ures have been investigated down to 20°K. The high temperature phase shows only one Iine and the Iow temperature phase only two. Neither of these is related to the R, (metbyi) rotation, which seems to remain pmctidiy free. However, the latter motion is found to be restricted in a newly discovered...

Rotation axes were calculated during active head movements using a motion analysis system. The mean rotation axis for 1 Hz head pitch when seated was posterior (6 mm) and inferior (21 mm) to the interaural axis, shifting 16 mm downwards when standing. During seated 2 Hz head pitch the rotation axis was close to the interaural axis, shifting downwards 15 mm when standing. This downward shift sug...

PURPOSES It has been reported that the amount of posterior tilt and upward rotation in scapular motions decreases with aging. The purposes of the current study were to investigate age related scapular motion regression and scapular restriction in patients with idiopathic frozen shoulder (IFS). METHODS The groups were recruited as follows: two groups of 50 asymptomatic subjects aged in their t...
