While many aspects of human vision at low light levels have been studied in great detail, motion perception has rarely been investigated so far. Here we address differential effects of light level on the perception of coherent motion, heading from radial flow, and biological motion. We determined detection thresholds under photopic, mesopic, and scotopic conditions. Results indicate that the pe...

One long-established simplifying principle behind the large repertoire and high versatility of human hand movements is the two-thirds power law-an empirical law stating a relationship between local geometry and kinematics of human hand trajectories during planar curved movements. It was further generalized not only to various types of human movements, but also to motion perception and predictio...

OBJECTIVES To investigate occupational factors associated with sick leave over a 4-year period in Australian employees. METHODS Longitudinal data (self-report) from 2861 Australian full-time employees (69.4% male) were used. Occupational factors and relevant covariates were assessed at baseline with sick leave assessed yearly over a 4-year period. The data were analyzed using multinomial logi...

The results of treatment of Lisfranc injuries are often unsatisfactory. This retrospective study investigated 46 patients with isolated Lisfranc injuries at a minimum of two years after surgery. Thirteen patients had a poor outcome and had to change employment, or were unable to find work as a result of this injury. The presence of a compensation claim (p = 0.02) and a delay in diagnosis of mor...
