Light therapy has not been convincingly shown to help people with ALS

Original source

Light TherapyALSUntangled · 12 March 2021 (opens in a new tab)

An expert review found that light therapy has not been convincingly shown to benefit people with amyotrophic lateral sclerosis (ALS). At certain wavelengths and energy levels, it appears safe and has theoretically plausible mechanisms, but evidence of benefit remains insufficient.

Why this matters

People with ALS should not consider light therapy an established treatment based on the available evidence. Further research is needed to determine whether it helps and which treatment protocols might be appropriate.

Limitations and context

The evidence includes a single case report that did not provide enough detail to independently confirm the diagnosis or treatment benefit. The available source is an expert review, not a new clinical trial, and it identifies the need for further studies.
