Manual handling accounts for one-third of all workplace injuries in Australia, but two thirds of costs from injuries. The majority of these injuries are back injuries, but injuries to hands, arms and feet are also significant. For reported workers compensation cases in the years 1998-99, cases related to body stressing accounted for 38.5% of cases (excluding Victoria and the ACT) (NOHSC: New Workers Compensation Cases Reported, 1998-99,  Mechanism of Injury or Disease). Body stressing covers 'muscular stress while lifting, carrying or putting down objects, muscular stress while handling objects other than lifting, carrying or putting down, muscular stress with not objects being handled, and repetitive movement, low muscle loading'.
