No you can definitely not. Physiotherapists are not allowed to use dr before their names. They can't portray themselves as Medical practitioners. It is considered as an offence.  But after completing the masters in physiotherapy you are allowed to start a clinic. As a person with the masters degree in physiotherapy you are considered as a doctor and independent of starting your own clinic and to use DR as a prefix before your name. A bpt doctor can only prescribe medication along with a relavant authority or a doctor.

Thank you.
