An analysis of 959 reports on physical restraint episodes that occurred in mental hospitals within 6 months was carried out. The results indicate that physical restraint in the form of immobilization using strait-jackets and belts was applied in 209 cases (i.e. ta 12.4% of treated patients). Among behaviours justifying the use of physical restraint aggression against others, self-aggression, violent destroying of property and motor agitation prevailed aver mostly therapeutic reasons, troublesome behaviours, escapes, and other. Out of 959 episodes: 54.2% were in accordance with the statutory regulations, 33.7% – in formal accordance, but tacking sufficient justification, 3.8% – contrary to the regulations, 4.1% – doubtful, while 4.2% – on the patient's awn request. Legitimacy of physical restraint was found to be accepted mechanically by the doctor ordering the use of physical restraint and by director of the hospital.
