Samenvatting
A study of 124 patients between 1972 and 1974 tried to give an insight into several special questions concerning: type of motorcycle, circumstances of trauma, driving experience and the amount of personal protection including helmets and clothing. Users of helmets sustained head injuries in 45% compared to 60% among the unprotected riders. Severe injuries are diminished by the use of protective clothes from 52.9 to 28.1%.
