The dispersion of motorcycle related injuries and deaths might be a result of disparity in motorcycle helmet use. This study uses national roadside survey data, injury sentinel surveillance data and other national data sets in 2010 of Thailand, a country with high mortality related to motorcycle injuries, to explore the disparity in helmet use, explanatory factors of the disparity. It also asse...

Helmet use on ski slopes has steadily increased worldwide over the past years. A common reason reported for helmet non-use, however, is impaired hearing. Therefore, an intra-subject design study was conducted to compare hearing thresholds and sound source localization of 21 adults with normal hearing in an anechoic chamber when wearing a ski helmet and ski goggles or wearing a ski cap and ski g...

The effectiveness of helmets in extenuating the primary shock waves generated by the explosions of improvised explosive devices is not clearly understood. In this work, the role of helmet on the overpressurisation and impulse experienced by the head were examined. The shock wave-head interactions were studied under three different cases: (i) unprotected head, (ii) head with helmet but with vary...

OBJECTIVE To compare the distribution and observation of helmet use patterns among 4 common childhood leisure activities-bicycle riding, in-line skating, skateboarding, and scooter riding-in a setting with no helmet use legislation. DESIGN A cross-sectional, unobtrusive, direct observation of children engaged in 1 of the 4 activities was conducted during an 8-week period. SETTING Eight comm...

BACKGROUND Off-road motorized vehicle crashes are a common source of trauma among Alaska children. Injury morbidity is worse in Alaska Native children than non-Native children, but the reasons are unclear. OBJECTIVE To evaluate the differences in helmet use between the Native and the non-Native children, and to assess the impact of helmet use on injury patterns and outcomes. DESIGN This ret...

BACKGROUND Transportation by motorcycle and bicycle has become popular in Taiwan, this study was designed to investigate the protective effect of helmet use during motorcycle and bicycle accidents by using a propensity score-matched study based on trauma registry system data. METHODS Data of adult patients hospitalized for motorcycle or bicycle accidents between January 1, 2009 and December 3...

To determine if helmet removal causes a significant increase in lordosis of the cervical spine in ice hockey players, we radiographically assessed the position of the cervical spine in subjects immobilized to a standard spine backboard wearing shoulder pads both with and without a helmet. Ten adult male volunteers (ages, 18 to 28 years) with no previous history of cervical spine injuries were f...

BACKGROUND The incidence of bicycle helmet use and the factors associated with helmet use in Ontario are presented in this study. The Ontario Health Survey (1996), a population-based survey of Ontario residents, was used as the data source. METHODS As the factors associated with helmet use were found to differ between adults and teens, a separate analysis was performed for each age grouping. ...

Motorcycle crashes are a major public health concern and place economic stresses on the health care system. Helmets have been shown to reduce both motorcycle-related fatalities and head injuries. Universal motorcycle helmet laws in other states have shown to be effective at increasing helmet use. The current Rhode Island motorcycle helmet law does not require every motorcycle rider to wear a he...
