Source

A sham-controlled meta-analysis found short-term benefit in chronic non-specific low back pain, mainly in higher-dose non-acupuncture laser trials.

Evidence grade

low

Effect direction

mixed

Panel relevance

partially-replicable

Key findings

  • The review included 15 studies with 1,039 participants.
  • Pain reduction favored laser treatment in subgroups using at least 3 J per point.
  • The authors rated evidence as moderate for short-term benefit but called for rigorously blinded dosage-appropriate trials.

Caveats

  • A later systematic review reached a more negative conclusion for non-specific low back pain.
  • Clinical point-laser dose is not directly equivalent to broad LED panel exposure.
