Evidence-based practice relies on several skill sets which are based both on a three part perspective, and as a whole. In evidence-based practice, one should gather information from the following three sources:
A recently published (2017) comprehensive study review  showed that many different tools, methods and treatments provided a positive effect on oral motor exercise and development, which is promising. However, the study also concluded that within much of the research carried out, there were methodological weaknesses present, so one could not draw any solid conclusions.
This means that although we already know a lot about general oral motor exercise, we need both better and further studies to achieve greater knowledge, about which methods and practices are the most effective.
As we wait for new research, it is therefore necessary for the responsible clinician to implement quality control within his treatment by providing systematic follow-ups, as well as documenting the individual effects of the actions initiated . In addition, relevant individual information about the user's medical condition must be obtained and details on the personal goals and desired outcomes are for the particular user - see cf. an evidence-based practice.
