[Effects of elastic lumbar belts on the effect of a muscle training program for patients with chronic back pain]

Aim of the study was to evaluate the influence of elastic lumbar belts on the effect of muscle training for patients with low back pain.

97 male subjects aged from 23 to 42 years with and without low back pain participated in the investigation. The low back pain patients (n = 63) were randomized into a training group without and a training group with elastic lumbar belts and a control group. The subjects with healthy backs (n = 34) were divided age-matched into a training group with elastic lumbar belts and a control group. The three training groups took part in a muscle strenghtening program over 8 weeks. The control groups did not receive any alternative physiotherapeutic treatment. All groups were tested at the beginning, after 8 weeks and further 6 months later.

The data obtained for the control groups remained virtually unchanged over the period of investigation. However, a significant increase of the muscle flexibility of the lower limbs could be proved for the training groups. Furthermore the coordination between the lumbar spine and pelvis when flexing the trunk deeply forward was more leveled out for the training groups with patients suffered low back pain. The results confirmed a reduction for pain severity and for limitations in activities of daily living as well. The modifications for the criteria investigated were significant stronger for the training group with patients using the elastic lumbar belt.

The effectiveness of the muscle strengthening program for patients with low back pain could be improved significantly by means of the elastic lumbar belt as an applicable therapy instrument in the functional rehabilitation of spinal injuries.
