Abstract
Changes in work techniques, musculoskeletal symptoms and work ability were studied after occupationally-oriented rehabilitation courses for farmers experiencing low back or shoulder pain. Fifty-two women and 43 men participated. The OWAS analysis of work postures, biomechanical modeling of lifting techniques, and a questionnaire were used before and after the courses and after 1 year of follow-up. Bent and twisted postures or postures with the arms over the shoulders occurred more seldom after the courses and the follow-up. Changes in lifting techniques were minor. The musculoskeletal pain index decreased by 12 and 3 points for the women and men, respectively. The mean work ability index increased from 33.5 (men and women) to 36.5 (women) and 35.1 (men). This study showed that rehabilitation can produce significant, long-lasting effects on rehabilitees' work techniques, work ability, and subjective well-being.
