Brief Summary
The purpose of this study is to analyse the changes in back muscle size and strength following use of Dysport®, and to establish whether there is any association between pain reduction and change in strength, in patients suffering from chronic low back pain.

Outcome Measures
Primary Outcomes (2)
Pain reduction as assessed by the mean Visual Analogue Scale (VAS) during last 2 weeks. Assessments will be made at the initial time before injection and 1, 2, 3 months after injection.
Improvement in daily life activities and quality of life using the Oswestry Low Back Pain Questionnaire (OLBPQ), and Short Form-36 (SF-36). Assessments will be made at the initial time before injection and 1, 2, 3 months after injection.
Secondary Outcomes (3)
Changes of the total isometric lumbar extensor strength and separated angle using lumbar MedX machine.
Association between pain reduction and strength. Measurements will be performed at baseline, and 1, 2, 3 months after injection.
Change of the lumbar extensor muscular size in CT Measurement will be performed at baseline and 3 months after injection.
