There hasn’t been any scientific backing for technique being an injury risk as yet with all the other factors involved it is hard to work out the influence of technique. I have been lucky enough to spend time in a gait laboratory where we have shifted forces away from painful tissue by adjusting swing technique. We think this resulted in less pain however it is possible the tissue may have settled in time anyway! A good example of this would be in the film below describing Patrick Cantlay’s back issues. Essentially the answer was to get more power from the legs rather than generating lots of force with spine rotation.
