The aim of this study is to review the protective effect of a bicycle helmet on each facial location systematically. PubMed was searched for articles published before December 12, 2014. The data were summarized, and the odds ratio (OR) between the locations of facial injury was calculated. A statistical analysis was performed with Review Manager (The Nordic Cochrane Centre). Bicycle helmets pro...
The side of the head is vulnerable to trauma in bicycle injuries. Depreitere et al., demonstrated contact between a flat-faced pendulum, and the side of cadaver heads, when bicycle helmets was worn. Computer design methods were used to interpret these experiments, showing that typical helmets safely absorbed 75% of the impact kinetic energy before pendulum-to-head contact occurred. Furthermore,...
OBJECTIVE The aim of the study was to examine the interactions between alcohol, bicycle helmet use, experience level, riding environment, head and brain injury, insurance status, and hospital charges in a medium-sized city without an adult helmet law. METHODS A study of adult bicycle accident victims presenting to a regional trauma center over a 1-year period was undertaken. Data were collect...
We invoke a triple rationale to rebut Hooper and Spicer's argument against mandatory helmet laws. First, we use the laws of physics and empirical studies to show how bicycle helmets afford substantial protection to the user. We show that Hooper and Spicer erroneously downplay helmet utility and that, as a result, their attack on the utilitarian argument for mandatory helmet laws is weakened. Ne...
The side of the head is a frequent impact site for pedal cyclists, motorcyclists, and industrial workers. It is vulnerable to impact, yet many helmet standards do not have impact tests at the side of the helmet. Laboratory impact tests should reproduce the phenomena in real impacts, but usually they do not allow the headform to rotate, or ignore the effect of the neck on the motion of the head....
There has been an ongoing debate in Australia and internationally regarding the effectiveness of bicycle helmets in preventing head injury. This study aims to examine the effectiveness of bicycle helmets in preventing head injury amongst cyclists in crashes involving motor vehicles, and to assess the impact of 'risky cycling behaviour' among helmeted and unhelmeted cyclists. This analysis invol...
OBJECTIVES To document current bicycle helmet use in Winnipeg, Manitoba and nearby rural communities, and to identify target groups for a helmet promotion campaign. METHODS Cyclist helmet use was observed between 28 May and 20 August 1996 at a sample of urban and rural locations. Age, gender, helmet use, riding companion(s), location type, correct helmet use, and use of headphones were record...
OBJECTIVE To develop national and state level estimates for preventable bicycle related head injuries (BRHIs) and associated direct and indirect health costs from the failure to use bicycle helmets. METHODS Information on the effectiveness and prevalence of use of bicycle helmets was combined to estimate the avoidable fraction, that is, the proportion of BRHIs that could be prevented through ...
OBJECTIVE To compare availability, urban price, and affordability of child/family safety devices between 18 economically diverse countries. DESIGN Descriptive: urban price surveys by local safety organisations or shoppers. SETTING Retail stores and internet vendors. MAIN OUTCOME MEASURES Prices expressed in US dollars, and affordability measured by hours of factory work needed to buy a ch...
OBJECTIVE The purpose of this study was to evaluate the "Bike Smart" program, an eHealth software program that teaches bicycle safety behaviors to young children. METHODS Participants were 206 elementary students in grades kindergarten to 3. A random control design was employed to evaluate the program, with students assigned to either the treatment condition (Bike Smart) or the control condit...
