In the present study, data of bicycle crashes leading to medical attendance in acute hospital or to death which occurred between June 1(st) 2004 and May 31(st) 2006 were analyzed. The final results consisted of injury data and patient records obtained from Kuusankoski Regional Hospital and from the road accident investigation teams. The total number of cases was 216. The severity of the injurie...

The purpose of this research was to study the behaviour and attitudes of young cyclists in different urban environments towards wearing a helmet, and possible differences regarding the length of the cycle lanes in the surveyed cities. A survey was carried out among 546 schoolchildren, aged from 10 to 15 years, at primary schools in three Croatian cities: Zagreb, Vara`din and Samobor. A comparis...

This paper shows that the meta-analysis of bicycle helmet efficacy reported by Attewell, Glase, and McFadden (Accident Analysis and Prevention 2001, 345-352) was influenced by publication bias and time-trend bias that was not controlled for. As a result, the analysis reported inflated estimates of the effects of bicycle helmets. This paper presents a re-analysis of the study. The re-analysis in...

Bicycle helmet efficacy was quantified using a formal meta-analytic approach based on peer-reviewed studies. Only those studies with individual injury and helmet use data were included. Based on studies from several countries published in the period 1987-1998, the summary odds ratio estimate for efficacy is 0.40 (95% confidence interval 0.29, 0.55) for head injury, 0.42 (0.26, 0.67) for brain i...

This study investigated risk compensation by cyclists in response to bicycle helmet wearing by observing changes in cycling behavior, reported experience of risk, and a possible objective measure of experienced risk. The suitability of heart rate variability (HRV) as an objective measure of experienced risk was assessed beforehand by recording HRV measures in nine participants watching a thrill...

The performance of bicycle helmets was investigated in oblique impacts with a simulated road surface. The linear and rotational accelerations of a headform, fitted with a compliant scalp and a wig, were measured. The peak rotational accelerations, the order of 5 krad s when the tangential velocity component was 4 m s, were only slightly greater than in comparable direct impact tests. Oblique im...
