Paraspinous lidocaine injection for chronic nonspecific low back pain: A randomized controlled clinical trial

In this large, sham-controlled, randomized trial, we examined the efficacy of the combination of standard treatment and paraspinous lidocaine injection compared with standard therapy alone in chronic low back pain. There is little research-based evidence for the routine clinical use of paraspinous lidocaine injection for low back pain. A total of 378 subjects with nonspecific chronic low back pain were randomized to 3 groups: paraspinous lidocaine injection, analgesics, and exercises (group 1- LID-INJ); sham paraspinous lidocaine injection, analgesics, and exercises (group 2- SH-INJ); and analgesics and exercises (group 3- STD-TTR).
