In the third and final episode looking at novel treatments for injury, I look at the evidence supporting the use of Low Levels Laser Treatment (LLLT). This is a widely available procedure with no really well understood mechanism of action. Is there evidence to suggest that it might be useful? Plus, a conversation with up and coming Australian professional triathlete Steve McKenna. After an injury forced him to take time off from Aussie Rules football, McKenna discovered his natural abilities in multisport and he has never looked back.
