- 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 designed 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 aimed at altering life style factors may represent an effective method for dealing with musculoskeletal pain problems.

- The purpose of the present study was to compare intensity levels assessed on Borg's Category Scale for Ratings of Perceived Pain (BRPP) (1982) (a verbal scale using adjectives and adverbs combined with the numbers 0-10), with assessments on the Visual Analogue Scale (VAS) (a 10 cm horizontal line). Eight healthy subjects volunteered in an experimental study, where pain was provoked by load on passive soft tissue elbow joint structures. Each subject participated 4 times on different occasions in the same experimental set-up, which was divided into six 2 min periods; 3 periods with load induced by applied external weights causing load moments of 3.4 Nm, 4.5 Nm and 6.8 Nm plus that induced by the weight of the lower arm and hand (average 2.9 Nm), followed by 3 periods without external weights. Each series consisted of 12 assessments given during the last 10 sec period of each minute on either the BRPP or the VAS. No significant difference was found between the first and second time a scale was used by the same subject, and none between the assessments on the VAS and the BRPP. Intensity levels of pain increased with load and time and decreased after reduction of the load moments. It is concluded that both scales can be used to reliably assess intensity levels of perceived pain elicited by loading joint structures. Intensity levels, as assessed on both scales, are associated with applied external load and time for exposure.
