English title: Treatment of low back pain and effectiveness of Sling-Exercise-Therapy (S-E-T). An experimental study was carried out to compare S-E-T-Training versus conventional strengthtraining regarding their effectiveness in the therapy of low back pain.

The parameters of interest were maximum strength of the trunk muscles (flexion/extension), spine stabilization, pain intensity and general well-being. The S-E-T Training method proved to be highly effective in improving trunkstabilization. There were no significant differences concerning the maximum strength. Both training groups were able to reduce their pain intensity and increase their general well-being.
