Prone Mechanical Traction for Low Back Pain

Supine Mechanical Traction Clinical Prediction Rule

Subgroup Identification

  • Presence of lower extremity symptoms (sciatica)
  • Signs of nerve root compression
  • Peripheralization with extension movements or crossed straight leg raise
Fritz et al. Is there a subgroup of patients with low back pain likely to benefit from mechanical traction? Results of a randomized clinical trial and subgrouping analysis. Spine. 2007 Dec 15;32(26):E793-800.

The results of this study suggest this subgroup is characterized by the presence of leg symptoms, signs of nerve root compression, and either peripheralization with extension movements or a crossed straight leg raise. Further research is needed to validate this finding.Fritz et al.

In the treatment of patients with signs of lumbar nerve root compression, the addition of mechanical traction to an [extension-oriented treatment approach (EOTA)] failed to show added benefit. There were no significant differences in pain and disability over either the short- or long-term follow-up periods between those receiving EOTA and those receiving EOTA in combination with mechanical traction. Furthermore, we were unable to validate a subgroup of individuals more likely to respond to mechanical traction.Thackeray A, Fritz JM, Childs JD, Brennan GP.
