A study published in the Journal of Foot and Ankle Research in 2014 investigated the effects of red and infrared light therapy on patients with chronic plantar fasciitis. The researchers found that participants who received the light therapy experienced significant reductions in pain and improvements in functional outcomes compared to a placebo group.
Another study published in Lasers in Medical Science in 2018 examined the effects of red light therapy on patients with diabetic peripheral neuropathy, a condition that can cause foot pain. The researchers found that participants who received the light therapy experienced a significant reduction in pain compared to a control group.
A systematic review and meta-analysis published in the journal Pain Research and Management in 2020 analyzed multiple studies on the use of red light therapy for various types of musculoskeletal pain, including foot pain. The review concluded that red light therapy was effective in reducing pain intensity and improving physical function.
