Eighteen former and active boxers underwent neurological examination, EEG, computed tomographic scan of the brain, and neuropsychological testing. Eighty-seven percent of the professional boxers had definite evidence of brain damage. All the boxers had abnormal results on at least one of the neuropsychological tests. Brain damage is a frequent result of a(More)
To improve understanding of slip propagation mechanisms, one could compare features of early stance phase during slips and non-slips. This study investigated the similarities and differences in kinematics and utilized COF of paired trials, defined as a matched pair of slip and non-slip trials produced by the same participant walking on the same floor(More)
A human-centered measure of floor slipperiness could be useful as an adjunct to conventional tribologic measures. This paper reports on the development and evaluation of a measure of slip distance based on variables derived from the signal of a heel-mounted accelerometer. Twenty-one participants walked on a laboratory runway under several surface(More)
Standing after maintaining working postures may result in imbalance and could elicit a fall. The objective of this study was to assess the magnitude of this imbalance. Forty-five male participants completed three replications of conditions created by four static postures and three durations within posture. Participants transitioned to quiet standing at a(More)
Determination and integration of human force capabilities and requirements is an essential component of ergonomic evaluation. With regard to hand-intensive tasks, direct force measurements can be cumbersome and intrusive. Here, the use of surface electromyography (EMG) was evaluated. EMG was obtained from three standardised electrode sites on the forearms(More)
Detailed neurological examinations, EEG and CT scans of the head were performed on 10 professional boxers aged 20 to 31 years shortly after being knocked-out. Intracerebral and subdural haematomas were not suspected or discovered. However, CT scans revealed cerebral atrophy in five of the boxers; this finding was most common in the boxers with the most(More)
Time-to-contact (TtC) is an alternative measure of postural stability to center of pressure (CoP) velocity. TtC is based on both spatial and temporal aspects of CoP displacement, definition of the boundary shape, and quantity of minima analyzed. Three boundary shapes and three minima selection methods were used to compute TtC during bipedal quiet standing.(More)
Three pointing devices (mouse, touch pad, touch screen) were evaluated for usability with a WindowsTM-style menu selection task while in a moving off-road environment. A pilot study determined which commercially available devices had the potential to promote good performance in the environment. Eighteen subjects performed a series of complex pointing tasks(More)

The flexible wooden boards are still being used on the scaffolds at some construction worksites in China. We examined if the board dimension, acclimation phase and construction work experience influence workers' walking strategies on these boards. Among the 40 construction workers recruited, half of them had more than 1 year of construction work experience.(More)
