Purpose
The Orthotics and Prosthetics User’s Survey (OPUS) is a self-report questionnaire consisting of five modules. It can be used for prosthetic and orthotic programs for quality assessment, to maintain awareness of improvement in activities, to evaluate changes in patient’s functional status and quality of life, and to assess satisfaction with devices and services.
- OPUS has an original and a modified version. Both the versions have of total five surveys:
1) The Upper Extremity Functional Status Survey(UEFS)
2) The Lower Extremity Functional Status Survey (LEFS)
3) OPUS-Health Related Quality of Life Index (HR-QOL)
4) OPUS-Satisfaction with Devices (CSD)
5) OPUS-Satisfaction with Services (CSS)
- Total items in the original OPUS are 87, and total items in the modified OPUS are 88.
- Different authors have used scoring for OPUS in a different way, so there is no minimal or maximal score reported. For example, the UEFS has a 5-point Likert scale where Score Points are 0 = not able, 1 = difficult, 2 = easy, 3 = very easy scores are given. The fifth column “not applicable is not scored” by some authors, or scored as “0” and added in the calculation. A total of these score points are considered at the final calculation.
- The LEFS and HRQOL are also based on a five-point Likert scale and a nominal YES-NO scale. The CSD and CSS use a four-point Likert scale.
- Easy to understand self-report questionnaire/survey.
- It can be administered through at clinic (preferred method). However, many studies have administered it via mail, as well as completion at home. These versions are not different from the original forms, and have not been specifically validated for use via mail or at home.
