SI diagnostic blockade
Study hypothesis
1. In patients with non-specific low back pain, 10 ml lidocaine 2% reduces the pain more than 2 cm at the BOX-score compared to the placebo group
2. In patients with non-specific low back pain, 9 ml lidocaine 2% with 1 ml corticosteroid (40 mg methylprednisolone) reduces pain more than 2 cm at the BOX-score compared to the placebo group
3. In patients with non-specific low back pain, 9 ml lidocaine 2% with 1 ml corticosteroid (40 mg methylprednisolone) reduces pain more than 2 cm at the BOX-score compared to the lidocaine group

Intervention type
Drug
Phase
Not Specified
Drug names
lidocaine, methylprednisolone
Primary outcome measure
The effect of the diagnostic blockade is evaluated through a 10 items BOX-score (box 1 represents no pain, box 10 represents the worst imaginable pain). Patients will fill the BOX-score (diary) in at home 3 times a day, for at least 4 weeks after a blockade.
Secondary outcome measures
With the Roland Disability questionnaire and Oswestry Low Back Pain Disability Index the limitation caused by low back pain will be assessed. Global health will be assessed using the short form (SF)-36 and COOP-Wonca questionnaire. Additionally the duration of a pain free period and daily pain medication use will be reviewed.
