Prolotherapy as a Regenerative Treatment in the Management of Chronic Low Back Pain: A Systematic Review.

: Chronic low back pain markedly impairs quality of life and imposes a significant economic burden on public health. The complex pathophysiology of chronic low back pain arises from the complex anatomical configuration of the lumbar region, which includes a diverse array of structures. Consequently, etiologies may involve intervertebral disc degeneration, facet joint osteoarthritis, spinal stenosis, spondylosis, and spondylolisthesis. Therapeutic interventions for chronic low back pain are equally varied, ranging from pharmacological treatments to physiotherapy, kinetotherapy, balneotherapy, and image-guided local injectable procedures such as prolotherapy. Prolotherapy is a regenerative injection technique designed to stimulate the body's healing processes by applying a regenerative treatment (typically dextrose), which aims to modulate neurogenic inflammation and diminish nociceptive signaling. : A systematic review of the literature was performed in alignment with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Studies published within the last ten years evaluating the effects of prolotherapy on pain reduction in individuals with chronic low back pain were included, following a search across six databases. Results: The review revealed several studies evaluating the influence of prolotherapy on pain in chronic low back pain patients. Findings were heterogeneous, with some studies indicating significant pain reduction and others showing minimal or no improvement. : The current evidence regarding the efficacy of prolotherapy for pain relief in chronic low back pain remains inconclusive, highlighting the necessity for further in-depth research. Continued and updated investigations into prolotherapy's role are imperative for enhancing the quality of life of affected patients.
