There is a lot of much needed skepticism on the internets these days in regard to the idea that we can diagnose movement “dysfunction” and prescribe movement “correction.” A lot of this debate centers on the FMS and other systemic approaches to improving quality of movement. I think a lot of this discussion is useful and productive. I also think that the level of skepticism sometimes goes too far, veering into what I call “movement relativism” - the idea that one movement will work just as well as another for a given purpose, or that we don’t have the slightest idea how to tell whether one way of moving is better than another.
