Radial Extracorporeal Shock Wave Therapy for Chronic Non-specific Low Back Pain

"rESWT will be performed as follows:~* Four rESWT sessions~* One rESWT session per week~* 4 × 1000 radial extracorporeal shock waves (rESWs) per session (1000 rESWs each applied to the left and the right paravertebral muscles above L3 to S1 using the 36-mm applicator, plus 1000 rESWs each applied to the left and the right sacroiliac joint using the 15-mm convex applicator, in prone position of the patient.~* rESWs applied at 15 Hz~* Air pressure of the rESWT device gradually increased during the first 200 rESWs each until the maximum discomfort the patient can tolerate will be reached, followed by 800 rESWs at this air pressure / energy flux density.~* No application of local anaesthetics"

1 x 200 mg per day for moderate pain (Numerical Rating Scale score 4-6 on an 11-point scale where 0 indicates no pain and 10 indicates worst imaginable pain), or 2 x 200 mg per day (Numerical Rating Scale 7-10), respectively, for four weeks

3 x 50 mg per day for four weeks
