The effects of the addition of mechanical traction to physical therapy on low back pain? A systematic review with meta-analysis

Objective: This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) on the comparative effects of different types or parameters of lumbar traction in low back pain (LBP).

Methods: CENTRAL, CINAHL, ISI Web of Science, PEDro, PubMed, and Scopus databases were searched from their inception to March 31, 2021. We considered all RCTs comparing different types or parameters of lumbar traction on adults who complained of LBP with or without lumbar radiculopathy (LR). Any restriction regarding publication time or language was applied. Two reviewers independently selected the studies, performed the quality assessment, and extracted the results. Meta-analysis employed a random-effects model.

Results: Sixteen studies met the inclusion criteria for qualitative analysis, and five were pooled. Meta-analyses of results from five studies on LBP with LR showed no significant difference between diverse tractions modalities at short-term follow-up. Very low to low-quality evidence supports these results. High-force and low-force traction demonstrated clinically significant improvements in pain.

Conclusion: The literature suggests the short-term effectiveness of traction on pain in LBP with LR, regardless of the type or the dosage employed. Different effects of traction other the mechanical ones can be hypothesized. This systematic review may be relevant for clinical practice due to the similar effects of different traction types or dosages.
