Capillus Red LightTherapy Mat uses low-level red light therapy (photobiomodulation) to help relieve pain and promote healing in muscles and soft tissues. The device delivers specific wavelengths of red light that penetrate the skin and may help reduce inflammation, improve circulation, and support tissue recovery. For back pain, the blanket design allows the light to cover a larger treatment area, making it easier to treat the entire back at once. It is a noninvasive therapy that can be used at home and is generally well tolerated. While some patients report improvement in pain and stiffness, results can vary and it is usually used as a complement to other back pain treatments rather than a standalone therapy.
