Turkish Validity and Reliability of Short-Western Ontario Rotator Cuff Disability Index

The aim of this study is to adapt the Short-Western Ontario Rotator Cuff Disability Index (SHORTWORC) to Turkish society and to make its validity and reliability in Turkish. The Western Ontario Rotator Cuff Disability Index (WORC) developed by Kirkley et al assesses quality of life in patients with Rotator Cuff İnjury. The WORC has 21 questions. The WORC was shortened and renamed as Short-Western Ontario Rotator Cuff Disability Index (SHORTWORC). The SHORTWORC consists of 7 questions. This study will be conducted with patients with rotator cuff injuries. The patients will be sought to answer questionnaires during regular rehabilitation sessions. 35 participants will be included in the study. In order to evaluate the validity of the SHORTWORC, the Western Ontario Rotator Cuff Disability Index (WORC), which can evaluate the quality of life in patients with rotator cuff injury and has been validated in Turkish, and the The University of California-Los Angeles (UCLA) shoulder scale, which can evaluate the functionality of shoulder and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.

About this study

The reliability and validity of the scale will begin with language equivalence and cultural adaptation. The scale will be translated from English to Turkish by two people who are fluent in Turkish and English. A single Turkish translation will be obtained from these two Turkish translations with a common opinion.

The scale, which has been translated into Turkish, will be translated into English by two other people who are fluent in Turkish and English. The scale translated into English will be compared with the original. In the pre-trial phase, a reassessment will be conducted with 15 participants to test the intelligibility of the scale. Based on the results of the pre-test phase, the final version of SHORTWORC will be able to be modified. The data of SHORTWORC are collecting through face-to-face when the patients came to the rehabilitation center. 35 participants will be included in the study.

In order to evaluate the validity of the SHORTWORC, the Western Ontario Rotator Cuff Disability Index (WORC), which can evaluate the quality of life in patients with rotator cuff injury and has been validated in Turkish, and the University of California-Los Angeles (UCLA) shoulder scale, which can evaluate the functionality of shoulder and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.

Scale validity and reliability

Other

The aim of this study is to adapt the Short-Western Ontario Rotator Cuff Disability Index (SHORTWORC) to Turkish society in patients with rotator cuff injury and to make its validity and reliability in Turkish. It has 7 questions. The patients will be sought to answer questionnaires during regular rehabilitation sessions.

Primary outcomes

Disability

Time frame: baseline

Disability will be assessed with the Short-Western Ontario Rotator Cuff Disability Index (SHORTWORC) in patients with rotator cuff injury. It haf 7 items. Each item is scored on a 0-to-100-mm visual analog scale, summing a total score ranging from 0 (best possible score) to 700 (worst possible score). Higher scores indicate poorer quality of life.

Secondary outcomes

Functionality of shoulder

Time frame: baseline

Functionality of shoulder will be assessed with the University of California-Los Angeles (UCLA) shoulder scale. It contains a total of 5 questions belonging to 5 categories: Pain (scored from 1-10), Function (scored from 1-10), range of motion (scored from 0-5), muscle strength (scored from 0-5), patient satisfaction (scored from 0-5). Each category is scored differently. Higher scores indicate better shoulder functionality.
