Trinity Scientist Wins European Research Grant to Study Brain Repair

Research is evolving, but several credible studies highlight red light therapy's promise: In preclinical (animal) models, near-infrared light delivered to the skull improved motor function and reduced lesion size. A small randomized controlled trial (RCT) of chronic stroke survivors reported better hand-grip strength and faster reaction times in the RLT group versus controls. Meta-analyses of photobiomodulation in neurological disorders suggest modest benefits for cognitive and motor outcomes when combined with standard therapy. Case series document improved speech fluency and limb coordination after adjunctive RLT sessions. While sample sizes are often small and protocols vary, the consistency of positive trends supports further investigation.

While research is still evolving, a growing body of studies supports RLT's role in post-stroke rehabilitation: Animal studies• Rodents treated with near-infrared light showed improved motor function and reduced lesion size.• Enhanced dendritic sprouting and neuron survival were observed in lab models. Pilot human trials• Small clinical trials report improvements in motor skills, balance, and mood when RLT is added to standard therapy.• Cognitive gains—in areas like attention and memory—have also been documented. Meta-analyses & reviews• Systematic reviews highlight RLT's safety profile and potential to accelerate recovery when combined with physical and occupational therapy. While these results are promising, larger randomized controlled trials are needed to define optimal dosing, timing, and patient selection.
