Abstract

Abstract: Background: Patient with chronic nonspecific low back pain is weakened ligament, and prolotherapy is the effective treatment but their use remains controversial. These ligaments can be strengthened by platelet-rich plasma injection. We hypothesized that the effectiveness of platelet-rich plasma injection and prolotherapy may decrease pain and improved disability of patient with chronic low back pain Methods: This study was a prospective, double-blind, randomized controlled trial and was conducted for 3 years for patient enroll and follow-up. Thirty-four patients with chronic nonspecific low back pain (duration of at least 3 months) refectory to conventional management were randomized to platelet-rich plasma injection and lidocaine injection. Patients were treated with weekly platelet-rich plasma or lidocaine injections at the lumbopelvic ligaments for 2 weeks and then weekly prolotherapy with 15% glucose for 2 weeks and followed up 6 months. Visual analog scale, Oswestry Disability Index, and Roland–Morris Disability Questionnaire were evaluated at initial, 4 weeks, 3 months, and 6 months. Four patients did not complete this trial. Three were in the platelet-rich plasma injection and 1 was in the lidocaine injection. Results: The intensity of pain was significantly decreased in platelet-rich plasma injections at 6 months as compared lidocaine injections; between-group differences were 0.9 (95% confidence interval 0.10–1.75 [ P = .027]). All participants were significantly decreased pain and disability index at 4 weeks, 3 months, and 6 months but there were no significant differences between groups except for visual analog scale at 6 months. The baseline parameters were no significant differences in both groups. Conclusions: In chronic nonspecific low back pain, the platelet-rich plasma injection in combination with prolotherapy is an effective intervention and either lidocaine or platelet-rich plasma injection significantly reduced disability. And injection at the lumbopelvic ligaments using the platelet-rich plasma and prolotherapy is also an effective treatment for pain.
