Ive never spent this much money on an app before, but after reading the great reviews decided to go for it. All of the maneuvers are on You Tube. So just search for CRTechnologies and save yourself $40. As a primary care provider, I personally think there are way too many maneuvers to sort through. There are so many tests to sort through without much direction to quickly decide which are best for your patient. If there were some sort of algorithm for quickly figuring out which special tests to perform if a patient has say neck pain radiating down the arm with numbness, that would be more relevant to me. If you are an orthopedic specialist and have extra cash to spend for a slightly more organized version of what you can find for free on You Tube, then go for it. Otherwise, save your money.
