Neck pain

Red light therapy for neck pain

Evidence for low-level laser therapy and photobiomodulation in acute, chronic, and myofascial neck pain.

Study count

The cited reviews include 16 RCTs with 820 patients and 13 RCTs with 556 myofascial neck pain patients.

Evidence grade

low

Panel relevance

partially-replicable

Bottom line

Neck pain content can say the evidence is promising for targeted PBM/LLLT, but should avoid diagnosing causes or promising relief from panels.

Consensus: LLLT has positive neck pain meta-analysis findings, but consumer panels are only partially comparable to targeted clinical laser protocols.

What the studies found

  • The 2009 Lancet review found reductions in neck pain compared with placebo or active control and follow-up effects up to 22 weeks after treatment completion.
  • The 2022 myofascial neck pain review found improved pain and pressure-pain threshold.
  • Disability outcomes were less clear in the myofascial neck pain review.

Dosage and timing

WavelengthsNot settled nm
IrradianceNot settled
FluenceNot settled
Session timeVaried by trial.
FrequencyVaried by trial.
DurationMulti-session clinical courses; no universal home-panel protocol.
TimingNo strong time-of-day consensus.
Treatment areaPainful neck sites and myofascial trigger regions.
Device typesMostly low-level laser therapy devices.
NotesPain outcomes are clearer than disability outcomes.
  • Target location appears important; broad exposure should not be assumed equivalent.
  • No cited source establishes one consumer panel dose.
  • Protocol pages should clearly label clinical laser evidence versus LED panel extrapolation.

Caveats

  • Neck pain may involve neurological, injury, inflammatory, or structural causes.
  • Medical evaluation is appropriate for severe, persistent, radiating, or traumatic pain.
  • Panel heat and positioning around the neck should be handled conservatively.
