    Cross-Cultural Adaptation, Validity, and Reliability of the Turkish Version of the Cumberland Ankle Instability Tool for Athletes
    (Human Kinetics Publ Inc, 2025) Yazgan, E.A.; Karagözoğlu Coşkunsu, D.; Razak Özdinçler, A.R.
    CONTEXT: To cross-cultural translate the Cumberland Ankle Instability Tool (CAIT) to Turkish version (CAIT-T) and to evaluate the validity, reliability, and cutoff score of CAIT-T for Turkish athletic population. DESIGN: The English version of CAIT was translated to CAIT-T based on a guideline of cross-cultural adaptation. Fifty-two athletes with chronic ankle instability and 63 athletes without chronic ankle instability were included in the study. Construct validity was evaluated with correlations between the CAIT-T, Turkish version of Foot Ankle Ability Measure (FAAM-T), and Numeric Rating Scale. CAIT-T was completed twice by each participant at 7 to 10 days intervals to assess test-retest reliability based on the intraclass correlation coefficient, whereas Cronbach alpha evaluated internal consistency. Discriminative validity and content validity of the CAIT-T also evaluated. RESULTS: In construct validity, strong positive correlation was found between CAIT-T and Numeric Rating Scale perceived ankle instability (rho = -.771, P < .001), as well as moderate negative correlations with FAAM-T-activities of daily living and FAAM-T-sports (rho = -.448, P < .001 and rho = -0.541, P < .001, respectively). The CAIT-T demonstrated strong test-retest reliability (intraclass correlation coefficient score of .98) with a good internal consistency (Cronbach α: .85). Receiver operating characteristic curve showed a cutoff score of 26.5 (Youden index: 0.78, sensitivity: 0.57, specificity: 0.90.5). No ceiling or floor effects were observed. CONCLUSIONS: CAIT-T is a valid and reliable questionnaire for the assessment of chronic ankle instability in the Turkish athletic population.

    Measuring Shoulder Abduction Strength Using 2 Different Dynamometers: Comprehensive Intrarater and Interrater Reliability and Validity
    (Turkish Assoc Orthopaedics Traumatology, 2025) Atli, Ecenur; Topaloglu, Mahir; Hosbay, Zeynep; Ozdincler, Arzu Razak
    Objective: The purpose of this study is to investigate the intrarater and interrater reliability of handheld dynamometer (HHD) measurements in assessing isometric muscle strength of the shoulder abductors and to compare these results with those obtained using a fixed dynamometer (FD). Methods: The study involved 25 voluntary participants, all over the age of 18, asymptomatic (with no injuries in the upper extremity), and not engaged in overhead sports. The participants were evaluated twice by 2 different testers who were experienced in orthopedic rehabilitation, at 90 degrees of shoulder abduction in the scapular plane. On the first measurement day, Tester 1 performed measurements using both HHD and FD, while on the second measurement day, both testers used only the HHD. A 3-to 7-day interval separated the 2 measurement sessions. Paired-samples t-tests were used to evaluate the systematic bias between the testers. Spearman's rank correlation coefficient, intraclass correlation coefficient, standard error of measurement, and minimal detectable change were calculated. The statistical significance level was accepted as P < .05. Results: Data from 22 participants (15 women, 7 men; mean age: 23.00 +/- 3.19 years) were analyzed, as 3 individuals did not attend the final assessment. A strong correlation (r = 0.772) was found between Tester 1's HHD measurements and FD, while a similarly strong correlation (r = 0.748) was observed for Tester 2's HHD measurements. Excellent intrarater reliability (intraclass correlation coefficient [ICC]= 0.941) was found between Tester 1's measurements, and excellent interrater reliability (ICC= 0.889) was found between testers. Conclusion: Handheld dynamometer has demonstrated excellent interrater and intrarater reliability and high validity for assessing shoulder abductor muscle strength in research and clinical use. Since the muscle strength of testers using the HHD may influence the results, the FD may be a more appropriate option when the study population is stronger than the testers. Studies involving different clinical populations and testers with varying experience levels are needed to improve the relevance of the results. Level of Evidence: Level III, Diagnostic Study.
