OBJECTIVE To determine why people do or do not wear helmets while bicycling. METHODS A survey was conducted from August through October 1999. Two survey areas were chosen for this study: local public schools and paved bicycle trails. For the school arm of the study, 3 public elementary, middle, and high schools were selected from 3 different regions of Rochester, Minnesota, for participation ...

For weapon cueing and Head-Mounted Display (HMD), it is essential to continuously estimate the motion of the helmet. The problem of estimating and predicting the position and orientation of the helmet is approached by fusing measurements from inertial sensors and stereo vision system. The sensor fusion approach in this paper is based on nonlinear filtering, especially expended Kalman filter(EKF...

OBJECTIVE To estimate the impact of a mandatory motorcycle helmet law in Taiwan. METHODS Taiwan passed a mandatory helmet law in June 1997. Data were collected retrospectively from police reports, which include hospital data, to compare six months pre-law June to November 1996) with the same six months post-law (June to November 1997). RESULTS Motorcycle fatalities decreased 14% after the i...

The aim of this study was to investigate the association between helmet component characteristics with frequency and distribution of head and brain injury (diffuse and focal) among motorcyclists in Klang Valley, Malaysia. In Malaysia, helmet law was implemented in 1973 (MIROS, 2008). To date, high helmet wearing rate was observed among Malaysian motorcyclists (i.e. 90% among riders) (World Heal...

Parachute opening shock tests were conducted with an instrumented test manikin to measure and record transmitted neck loads. The standard paratrooper helmet, as well as two developmental helmet systems, were fitted to the manikin head. These two systems alter the headborne weight and center of mass from the standard helmet, potentially increasing the risk of acute neck injury during parachute o...

OBJECTIVE To evaluate the influence of average family income in a geographic area on the effectiveness of helmet legislation on observed helmet use by children (5-14 years). METHODS The study was conducted in East York, a health district of Metropolitan Toronto, in collaboration with the East York Health Unit. In 1996, the total population was 107 822, 11 340 of which were children 5 to 14 ye...

Since late 1989, the cycle helmet wearing rate in New Zealand has risen from around 20% for adults and teenagers, and 40% for younger children, to more than 90% in all age groups. Cycle helmet wearing became mandatory under New Zealand law in January 1994. This paper considers the effect of cycle helmet wearing on hospitalised head injuries between 1990 and 1996, using cyclist limb injuries as ...

BACKGROUND Despite increasing evidence indicating that wearing cycle helmets can reduce the severity of head injuries, particularly in children, there is a paucity of local data on cycle helmet ownership and wearing rates. These data together with an understanding of the factors which influence these rates are important in developing appropriate health promotion programmes. METHOD The objecti...
