AUTHORS ' CONCLUSIONS Very low quality evidence is available from single trials , thus we are uncertain if hip pre caution s with or without the addition of equipment and functional restrictions are effective in preventing dislocation and improving outcomes after THA .
BACKGROUND Total hip arthroplasty ( THA ) is one of the most common orthopaedic operations performed worldwide .
Painful osteoarthritis of the hip is the primary indication for THA .
Following THA , people have conventionally been provided with equipment , such as raised toilet seats and chairs , and educated to avoid activities that could cause the hip joint to be in a position of flexion over 90 degrees , or adduction or rotation past the midline .
These aspects of occupational therapy have been advocated to reduce the risks of prosthesis dislocation .
However , the appropriateness of these recommendations has been question ed .
OBJECTIVES To assess the effects of provision of assistive devices , education on hip pre caution s , environmental modifications and training in activities of daily living ( ADL ) and extended ADL ( EADL ) for people undergoing THA .
Questionnaire on the perceptions of patients about total hip replacement.
We developed a 12-item question naire for completion by patients having total hip replacement ( THR ) . A prospect i ve study of 220 patients was undertaken before operation and at follow-up six months later . Each completed the new question naire as well as the SF36 , and some the  Arthritis Impact Measurement Scales ( AIMS ) . An orthopaedic surgeon assessed the Charnley hip score . The single score derived from the question naire had a high internal consistency . Reproducibility was examined by test-retest reliability and was found to be satisfactory . The validity of the question naire was established by obtaining significant correlation in the expected direction with the Charnley scores and relevant scales of the SF36 and the AIMS . Sensitivity to change was assessed by analysing the differences between the preoperative scores and those at the follow-up . The st and ardised effect size for the new question naire compared favourably with that for the SF36 and the AIMS . The new question naire provides a measure of outcome for THR which is short , practical , reliable , valid and sensitive to clinical ly important changes
