Back problems associated with work have become expensive, indeed the most expensive musculoskeletal problem for Western societies [7, 17, 21, 48]. The back is so expensive because it is the most common cause of disability awards for people in the United States of America for persons under 45 years of age [17]. Although the expense is most attributable to disability and worker’s compensation in the industrial context, back problems seem almost unavoidable by the age of 50 and are the most common reason for a doctor’s appointment after the common cold [18]. Many have recommended approaches to reduce the impact but have had little influence on outcon [35]. |
