AbstractAs people with an intellectual disability are resettled from institutions, the likelihood increases that physiotherapists working in outpatient departments will have patients who have an intellectual disability. This study, therefore, sought to establish from a sample of 88 outpatient physiotherapists the degree of their knowledge of the All Wales Strategy for the Development of Services for the Mentally Handicapped, die adequacy of their experience and knowledge to treat this particular client group effectively and their attitudes towards people with intellectual disabilities. Although physiotherapists were generally aware of the principles of the AWS, 88% did not know its specific objectives. They had very little experience and knowledge of intellectual disability, 77% believing themselves inexperienced. Nevertheless, a large majority held positive attitudes towards this client group and agreed in principle with integration into the community. Training with respect to people who exhibit challenging behaviour was identified as necessary.
