It is not clear to what extent the health care professionals in Papua New Guinean hospitals are aware of the physiotherapy and rehabilitation services available to them. A study was conducted aimed at assessing the level of knowledge and perception of physiotherapy by hospital-based health professionals using a simple self-administered closed and open-ended questionnaire. 200 questionnaires were sent to each of five major hospitals but only 145 responses (15%) were received from different cadres of health professionals. Responses from nursing officers accounted for 46% (n = 67) while those from medical officers accounted for only 10% (n = 14). The respondents generally showed a lack of knowledge about physiotherapy services. It is suggested that inter-professional training and communication should be given greater attention during medical and health professional training to ensure that all health professionals are aware of the role and importance of physiotherapy services.
