ADAPTATION OF KEY QUESTIONNAIRES USED FOR THE ASSESSMENT OF THE CONDITION AND FUNCTION OF A SHOULDER JOINT IN PATIENTS WITH PAIN SYNDROMESOF DIFFERENT ETIOLOGIES
Introduction: Surgical interventions in patients with rotator cuff injuries, joint instability, adhesive capsulitis, synovitis, injuries of the long head of the biceps tendon, subacromial impingement, etc. have been growing in number each year. The evaluation of the function and state of the shoulder joint, as well as the choice of proper rating scales that are sufficiently informative and sensitive to clinical condition changes, are mandatory tasks for both orthopedists and physical therapists engaged in the process of diagnosis and treatment. To ensure correct and objective assessment of the function and state of a joint by meansof specialized questionnaires, these tools must be adapted to the linguistic and cultural makeup of the countries, where they are expected to be used, which can be achieved through direct and reverse translation based on strict rules. Objective: The objective of this study is to perform adaptation of the Russian versions of the four key questionnaires that are used for the assessment of the state of a shoulder in patients with pain syndromes of different etiologies. Materials and Methods: The Russian versions of the questionnaires were adapted based on recommendations of Beaton D.E. Results and Conclusions: The Russian versions of the questionnaires finalized in the course of the study are ready for use in further research and clinical practice. The adaptation algorithm that was employed has been field-proven in a number of countries. Apart from translation, all the questions where thoroughly analyzed from the perspective of the Russian national context. One of the most critical tasks was the translation of medical terms. However, despite all the highlighted challenges, none of the questionnaires proved to be difficult for understanding. The next step is validation.
