Background: Lateral elbow tendinopathy (LET) is one of the most common work-related or
sport-related pain disorders of the arm. Several instruments have been developed to determine the outcome of elbow conditions including LET. The PRTEE questionnaire which is an updated version of the Patient-Rated Forearm Evaluation Questionnaire (PRFEQ) is a 15-item questionnaire specifically designed for patients with LET. The PRTEE questionnaire, provides a very quick (it takes less than 5 min to complete), easy, and standardized quantitative description of pain and functional disability in patients with LET. It has been translated and culturally adapted into German, Italian and Swedish. There is no Greek version of the PRTEE questionnaire available at present. In order to administer this questionnaire to a Greek speaking population, a rigorous process of cross-cultural adaption and validation is needed.
Purpose: To cross-culturally adapt and validate the Greek version of the Patient-Rated Tennis Elbow Evaluation (PRTEE-G) Questionnaire.
Methods: Four bi-lingual translators were involved in the translation and cultural adaptation procedures. Eighty-two patients (61 women and 21 men) with LET participated in the study. To establish test - retest reliability, the patients were asked to complete the PRTEE-G Questionnaire before and after the first physiotherapy treatment. Internal consistency of the translated instrument was measured using Cronbach 'alpha'. An intraclass correlation coefficient was used to assess the test - retest reliability of the PRTEE-G Questionnaire. Concurrent validity was measured by correlating the PRTEE-G Questionnaire scores with the Greek version of the Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) scores using Pearson's correlation coefficient.
Results: The Greek PRTEE questionnaire has acceptable internal consistency (Cronbach 'alpha' =0.95), excellent test - retest reliability (ICC = 0.94) and demonstrates expected concurrent validity (r > 0.72).
Conclusion(s): The Greek version of PRTEE Questionnaire is a reliable and valid measure when administered to patients with LET.
Implications: The Greek PTREE questionnaire could be applied in a Greek-speaking population
to assess symptoms and functional limitations in patients with LET. It provides a useful assessment tool for cross-cultural research in patients with LET.
