RATIONALE, AIMS AND OBJECTIVES The basic single-group interrupted time series analysis (ITSA) design has been shown to be susceptible to the most common threat to validity-history-the possibility that some other event caused the observed effect in the time series. A single-group ITSA with a crossover design (in which the intervention is introduced and withdrawn 1 or more times) should be more r...

Research Note training have found mixed evidence for the effect of rider training on motorcycle crashes. Billheimer's (1998) matched-pair analysis of trained and untrained motorcycle riders is the only study conducted in the United States that has found a reduction in crashes among trained riders during the first 6 months following training. Among novice riders who rode less than 500 miles on a...

Accident studies emphasise the high frequency of perceptual errors made by car drivers when colliding with motorcycles (in 60 or 70% of these accidents, according to Van Elslande & Jaffard, 2010, and Hurt et al., 1981, respectively). The errors are identified as non (or late) detections of the motorcycle on the one hand (e.g., Cavallo & Pinto, 2012), and as a misperceptions of the motorcycle's ...

www.ums.ac.uk To determine what degree of causality rainfall, dry days and motorcycle events had on trauma incidence we used a Spearman rank co-efficient (SPC). We found poor correlation between the peaks of motorcycling accidents & other vehicle road accidents in both 2008 and 2009 (SPC 0.292 and 0.177 respectively). Motorcycling accidents are most common in months with most official motorcycl...

The scope of this paper is to assess traffic accidents involving motorcycles, the victims involved and the increase in the fleet compared with other vehicles in Rio Branco, State of Acre. It is an epidemiological, descriptive and transversal study of accidents between 2005 and 2008 recorded by the Acre State Highway Department. There were 3,582 motorcycle accidents and 3,768 victims in the peri...

OBJECTIVES to evaluate the epidemiological profile, the surgical treatment and the postoperative results of patients with complex traumatic injuries to the lower limbs. METHODS we conducted a retrospective study of patients with traumatic complex injuries treated by the Plastic Surgery Service of a regional hospital in Brasília. We analyzed clinical-epidemiological data, type of surgical proc...

BACKGROUND The aim of study was to determine the occurrence of tooth injuries and associated factors among patients treated at a hospital emergency ward. METHODS A cross-sectional study was conducted involving the analysis of 790 patient charts. The independent variables were gender, place of residence and type of accident. The dependent variable was tooth injury (fractures, concussion, luxat...

The paper illustrates the research outcomes of the integration of sensor system and control logic into a multibody simulation environment for motorcycle accidental dynamics analysis. One of the main objectives is to propose feasible scenarios for intelligent collision avoidance scheme for powered two wheeler (PTW) systems. A multibody model of a motorcycle that comprises a simplified model of t...

BACKGROUND Motorcycle crashes are the cause of severe morbidity and mortality especially because of head injuries. It seems that wearing a helmet has an effective role in protection against head injuries. Nevertheless, motorcyclists usually have no tendency to wear a helmet when driving in cities and have several reasons for this behavior. OBJECTIVES This study aimed to evaluate the use and r...

Background. Perthe's syndrome (traumatic asphyxia) is rare, which is caused by sudden compressive chest trauma and characterized by subconjunctival hemorrhage, facial edema, craniocervical cyanosis, and petechiae on the upper chest and face and should always be kept in mind as a possible complication of injuries of the chest and abdomen. Case Report. In this case report a 36-years-old male pati...
