Objective: To study whether conservative correction in a leg-length discrepancy (LLD) of 10mm or less in patients with chronic low back pain (CLBP) can relieve pain.

Publication Type: Randomized, controlled intervention study, with a mean follow-up duration of 10 weeks.


  • Shoe inserts significantly reduced both pain intensity and disability.  A moderate positive correlation was found between LLD and the degree of pain relief after wearing shoe inserts. 

  • Shoe inserts appear to reduce CLBP and functional disability in patients with LLDs of 10 mm or less. 

  • It is possible that mild LLD is rarely treated because clinicians are not aware of  the potential for its correction.
