The secondary prevention of low back pain: a controlled study with follow-up
& NA ; The current investigation studied the effectiveness of a secondary prevention program for nurses with back pain who were deemed at risk for developing a chronic problem . A 2 × 3 repeated measures design was employed with 2 groups and 3 assessment periods . The treatment group received an intervention design ed to reduce current problems , but above all to prevent reinjury and minor pains from becoming chronic medical problems , and it included a physical and behavioral therapy package . The control group was placed on a waiting‐list . Results indicated that the treatment group had significantly greater improvements than the control group for pain intensity , anxiety , sleep quality and fatigue ratings , observed pain behavior , activities , mood , and helplessness . These differences were generally maintained at the 6 month follow‐up . In addition , the treatment group broke a trend for increasing amounts of pain‐related absenteeism , while the control group did not . Taken as a whole , the results suggest that a secondary prevention program aim ed at altering life style factors may represent an effective method for dealing with musculoskeletal pain problems
