The impact of the ankle and foot on the spine is enormous. The structure and function of the ankle-foot largely affects the position of the pelvis, which in turn affects the mechanics and structure of the entire spine. The ankle-foot is a very complex combination of structures and functions. A relatively small structure carries a tremendous amount of body weight and load in motion. This influence, in many places, will be narrowed down to a static role. Therefore, many interventions will start with how the structure is altered. For example, the use of arch pads for people with flat feet. In fact, such a treatment is incomplete. This is because, even with an increased arch, the weak muscles are still not able to control the movement of the ankle very well during walking. Injury is inevitable. Therefore, when considering the impact of the foot and ankle on scoliosis and seeking intervention, it is important to evaluate movement and make functional judgments in addition to static observations. The impact of ankle problems (e.g., flat feet) on scoliosis is not only static in the standing position. The assessment of foot and ankle problems and the development of a physiotherapy program are individualized. On the one hand, each patient is different, and on the other hand, the response to intervention is different. Therefore there is a continuum of treatment rather than a one-step approach. In some previous interventions, patients have asked why the intervention did not meet expectations. The reason is actually quite simple: there is no program that does not need to be adjusted. Whether it is the wearing of a brace or the implementation of a training method, all are needed.
