This article critically analyzes the literature pertaining to the inter- and intraobserver reproducibility of spinal palpation to investigate the consistency of study results and assess the level of evidence for reproducibility. The results showed that there was strong evidence that the interobserver reproducibility of osseous and soft tissue pain is clinically acceptable and that intraobserver reproducibility of soft tissue pain and global assessment are clinically acceptable. Other spinal procedures are either not reproducible or the evidence is conflicting or preliminary.
