No specific regulation has been found on osteopathy. Osteopathy might still be governed by Poland’s general regulation of CAM, which you can read about here. The Polish Osteopathy Society accepts members with recognized diplomas from osteopathy schools (Polska Szkoła Osteopatii /European School of Osteopathy)(229).
