BACKGROUND Conventional motion analysis studies define the ankle joint center as the midpoint between the most medial and lateral aspects of the malleoli, yet research points toward a more distal joint center location. The purpose of this study was to develop and evaluate an anatomically based correction that would move the conventional ankle joint center to a more accurate location. METHODS ...

OBJECTIVES/HYPOTHESIS Black patients generally present with advanced head and neck cancer resulting in decreased survival. The objective of this study was to determine whether equal access to laryngeal cancer care in a tertiary care Veterans Affairs (VA) Medical Center would result in similar survival for white and black patients. STUDY DESIGN Retrospective chart review. METHODS Patient and...

PURPOSE To investigate the effects of an imaginary and a visual target on torsional optokinetic nystagmus (tOKN) and directional symmetry of tOKN. METHODS Torsional OKN was induced by a rotating random dot pattern (52 degrees in diameter, constant angular velocity: +/-30 deg/sec to +/-52 deg/sec) with an imaginary or a visual target in 11 eyes of 10 healthy humans by dual-search coil methods....

parking area and inside the Bella Center, with a level of 6.0¡1.7 and 3.0¡0.9 mg?m, respectively. Peak values were 12.5 mg?m and 12.0 mg?m, respectively. However, outside in front of the Bella Center with smokers, mean PM2.5 was 17.8¡7.5 mg?m with a peak of 98.9 mg?m (p,0.03, as compared with inside the venue), which is a step down in AQI. PM2.5 along the motorway was only 4.6¡0.7 mg?m with a p...

objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...
