British Journal of Sports Medicine (BJSM) is a multi-media portal that provides original research, reviews and debate relating to clinically-relevant aspects of sport and exercise medicine, including physiotherapy, physical therapy and rehabilitation. We contribute to innovation (research), education (teaching and learning) and knowledge translation (implementing research into practice and policy). Our web, print, video and audio material, combined with active social media, serves the international community of clinicians who treat active people.
