To some degree yes, but that's why I offer MOTs. Gait retraining in studies only covers simple cues to change how a person runs. Almost inevitably this does create problems and inefficiencies. That's exactly why we assess, and then work to improve, the strength, mobility and gradual learning of gait changes, so that your body and brain can grow into a more efficient and lower risk running style. Gait retraining does work when it's done well and thoroughly.
