The cost-effectiveness of a back school program in industry. A longitudinal controlled field study.

To define the cost-effectiveness of a back school program in industry, a controlled longitudinal field study was carried out in a Dutch bus company. The experimental group received a program consisting of information on back care, physical fitness, nutrition, stress, and relaxation. Objective data on absenteeism were collected and compared during a 6-year period for the control and experimental groups. Results showed that a tailor-made back school program reduced absenteeism by at least 5 days per year per employee, therefore being cost-effective to industry. A reduction was not observed in incidence, but in mean length of absenteeism. This effect turned out to be persistent during a 2-year period following the program.

Patterns of muscular activity during movement in patients with chronic low-back pain.

Bilateral paraspinal electromyogram (EMG) at levels L1-L2 and L4-L5, and abdominal EMG of a group of 20 low-back pain patients were compared to those of a group of 20 pain-free controls during flexion, extension, lateral bending to right and left, and rotation to right and left. The results showed no significant left-right differences in paraspinal EMG levels between low-back pain patients and pain-free controls during any of the movements. However, patterns of paraspinal and abdominal EMG were found to be different for low-back pain patients compared to pain-free controls during flexion only.
