So much of the current research pertinent to the expansion of the field especially in regards to shoulder and knee examination, diagnosis, and treatment are found on this site, much of which is contributed by Mike himself. His site, in my own opinion, is an unbelievable avenue for all therapists to grow and be able to interact w/ one another in regards to endless topics. Best site by far out there for physical therapists or anyone involved in musculoskeletal related fields!
