Turkish Validity and Reliability of Baltimore Orthopedic Subscapularis Score

The aim of this study is to adapt the Baltimore Orthopedic Subscapularis Score (BOSS) to Turkish society and to make its validity and reliability in Turkish. The BOSS was developed by Hameker et al to differentiate subscapularis tears from other rotator cuff muscle tears in patients with rotator cuff injuries. The BOSS has 5 questions. This study will be conducted with patients with rotator cuff injuries. The patients will be sought to answer questionnaires during regular rehabilitation sessions. 25 participants will be included in the study. In order to evaluate the validity of the BOSS, the Western Ontario Rotator Cuff Disability Index (WORC), which can evaluate the functionality of the shoulder in patients with rotator cuff injury and has been validated in Turkish, and the SF-12 which can evaluate the quality of life 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 BOSS will be able to be modified. The data of BOSS will be collecting through face-to-face when the patients came to the rehabilitation center. 25 participants will be included in the study.

In order to evaluate the validity of the BOSS, the Western Ontario Rotator Cuff Disability Index (WORC), which can evaluate the functionality of shoulder in patients with rotator cuff injury and has been validated in Turkish, and the SF-12 which can evaluate the quality of life and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.

Treatment and study plan

Scale validity and reliability

Other

The aim of this study is to adapt the Baltimore Orthopedic Subscapularis Score (BOSS) to Turkish society in patients with rotator cuff injury and to make its validity and reliability in Turkish. It has 5 questions. The patients will be sought to answer questionnaires during regular rehabilitation sessions.

Primary outcomes

  1. Disability

    Time frame: baseline

    Disability will be assessed with the Baltimore Orthopedic Subscapularis Score (BOSS) in patients with rotator cuff injuries. It has 5 items. Each item is scored on a 1-to-5, a total score ranging from 5 (best possible score) to 25 (worst possible score). Higher scores indicate a higher disability.

  2. Functionality of the shoulder

    Time frame: baseline

    Functionality of the shoulder will be assessed with the Western Ontario Rotator Cuff Disability Index (WORC) in patients with rotator cuff injuries. It has 21 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 2100 (worst possible score). Higher scores indicate poorer functionality.

Secondary outcomes

  1. Health status

    Time frame: baseline

    Health status will be assessed with the SF-12. It has 12 items. It has eight sub-dimensions and two summary scores: physical and mental. In the total score obtained from the scale, 100 indicates the best health status, while 0 indicates the worst health status.
