    Notes: Summary Several new studies have indicated that an active approach to patients with chronic disabling low back pain (LBP) seems effective. Some of these studies emphasize the importance of dealing with the patient's total situation in comprehensive multidisciplinary programs — the bio-psycho-social model. However, these programs are expensive. The aim of this study was to evaluate the rehabilitation outcome from three different active programs in terms of: (1) return-to-work rate, (2) days of sick leave, (3) health-care contacts, (4) pain and disability scores, and (5) staying physically active. The subjects included 132 patients randomized to the study, of whom 123 started one of the treatment programs. They had all had at least 6 months of chronic LBP. The patients were randomized into one of three programs: group 1 — a full-time, intensive 3-week multidisciplinary program, including active physical and ergonomic training and psychological pain management, followed by 1 day weekly for the subsequent 3 weeks; group 2 — active physical training, twice a week for 6 weeks, for a total of 24h; group 3 — psychological pain management combined with active physical training, twice a week for 6 weeks, also for a total of 24h. The results presented here are based on data collected 4 months following treatment, which shows an 86% response rate. The initial examination and the follow-up evaluation were performed by a blinded observer. The results show that 4 months after treatment, the intensive multidisciplinary program is superior to the less intensive programs in terms of return-to-work rate, health-care contacts, pain and disability scores, and staying physically active. In conclusion, it seems that although the multidisciplinary program is initially expensive compared to the less intensive programs, the savings in sick pay, early retirement pensions, and health care contacts make it economically worthwhile. Long-term follow-up will show whether this effect continues.

    Notes: Summary A method for evaluation of muscular contraction frequencies during prolonged work is presented. It is based upon computer-aided electromyographic (EMG) analyses. Variations in muscular tension, expressed as the relative force of contraction or torque in the joint, are followed using previously described EMG techniques. The number of times muscular tension crosses an amplitude band from below is then estimated. The band represents a predetermined range of amplitude. It is moved in steps from the lowest to the highest force level which occurred during the work task, and the frequency of band-crossings is computed for each band position. The frequencies are then plotted against the force levels at which the upper limit of the band was placed. From this relationship a frequency/force index is computed. The analysis is repeated several times using different band-widths. Thus, the method considers the contraction frequencies according to the load levels. It was developed to study the function of the musculo-venous pump in the legs during prolonged sedentary work, but might also be used to analyse such factors as muscular strain during work.
