amongst professionals in medical practices the action of waste by physiotherapist is of importance to study. This is because unlike other medical practitioners, who may ultimately prescribe medicine and their responsibility is considered based on the principle of causation, physiotherapists are mostly working directly on the body of patients and their responsibility is governed by the principle of waste/ destruction which assimilates their responsibility to that of surgeons. As a summery, it can be claimed that a physiotherapist's responsibility based on the principle of waste is presumed unless the opposite (the innocence) is proven. Some examples of physiotherapists' responsibilities are injuries caused in practice therapy such as physiotherapy and rehabilitation of heart patients,.practices, mobilization of PNF joints, etc.
