In Birmingham, groundbreaking research led by Professor Zubair Ahmed and his team at the University of Birmingham has unveiled promising results in treating spinal cord injuries (SCI) using red and near-infrared light. This innovative therapy may offer hope for functional recovery to those afflicted with such devastating injuries.
The team’s study, published in the renowned journal Bioengineering & Translational Medicine, outlines a precise ‘dose’ of light therapy that can produce significant therapeutic advancements. Notably, this includes the substantial restoration of sensation, movement, and nerve cell regeneration. This finding comes after meticulous examination of cell models to assess the adequacy of frequency and duration of light exposure for maximum rehabilitation and nerve cell regrowth.
Research indicates that utilizing red light with a wavelength of 660nm for just one minute daily can enhance cell viability by 45% across a five-day treatment period. The effectiveness of this treatment is twofold as it protects and promotes the survival of nerve cells while also encouraging their growth.
Professor Ahmed and his team extended their examination to preclinical models of SCI, employing two methods of light therapy delivery—an implantable device and a non-invasive technique called transcutaneous delivery. Both techniques yielded similar outcomes, significantly reducing tissue scarring and substantially enhancing function post-injury. Furthermore, they observed notable reductions in scarring and cavities at the injury site, augmented levels of proteins linked with nerve regeneration, and improved connections between spinal cells.
