This essential reading aims to provide a compact and understandable overview of the legal complexities surrounding the topic of alternative practitioners for physiotherapy. The content is easy to implement even for those without a legal background. Since physiotherapists have the opportunity to obtain a license as an alternative practitioner limited to the field of physiotherapy, the author has been intensively engaged with this topic.

After all, there are some pitfalls that do not arise for the average physiotherapist. Several of the topics discussed here are also of great importance.
