Abstract: The high incidence rate of occupation-related low back injury was known to cause enormous loss in economy and human resources. Insofar as traditional preventive measures are concerned, employee training and education were the main focus. However, mere provision of lifting training was demonstrated as ineffective in combating the problem. Back care training together with an ergonomic approach was therefore suggested in a bid to tackle high back injury incidence in health care settings. An ergonomic approach aims to develop a safe working system, which seeks to match the work tasks with worker's capabilities. A valid and reliable risk factor analysis tool is then indispensable. Existing risk factor analysis tools for health workers, in the form of assessment checklist, fall short in providing a comprehensive assessment for people suffering from cerebral palsy because the checklists are not patient specific. Furthermore, these assessment forms suffer from another major setback and that is information of their reliability and validity. This study aims to develop a valid and reliable risk factor analysis tool for people suffering from cerebral palsy and to compare the reliability of professional and non-professional staff in assessment implementation.
The newly developed assessment form was designed based on six assessment forms from various countries. A group of six experts from the field of physiotherapy, occupational therapy, nursing and bioengineering were invited to validate the new assessment form. Good content validity with Content Validity index (CVI) of I was found for the entire instrument. Then the subjects of professional and nonprofessional staff assessed 20 clients with cerebral palsy based on the new form. The same assessment was conducted again a week later to investigate the intrarater reliability. It was found that the Intraclass Correlation Coefficient (ICC) values of professional staff in both interrater and intrarater reliability were superior to the nonprofessional staff. Significant difference was also found in the mean rating scores of individual questions of the assessment form (p <0.05). In general, non-professional staff rated the client as more risky than the professionals. In conclusion, the professional staff rated the clients in a more consistent manner than their nonprofessional counterparts and different perceptions on the risk level existed among two subject groups. Small sample size, homogeneity of client's characteristic and functional ability are the major limitations of this study. Further studies conducted in other service centers for people suffering from cerebral palsy were suggested to overcome the limitations.
