    Purpose: To translate Diabetes-39 quality of life scale (D-39) into Turkish, to accomplish a cross-cultural adaptation, to demonstrate validity and reliability of Turkish version (D-39-TR). Methods: A total of 214 patients with type 2 diabetes were included, with an average age of 52.59 ± 14.83, a female/male ratio of 51/49%. Internal consistency and test-retest reliability were assessed by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. For structural validity, factor analysis was used. The SF-36 was used for convergent validity, and hemoglobin A1c (HbA1c) was used for differential validity. Results: The Cronbach's alpha coefficient was over 0.70 for all subscales of D-39-TR and it was 0.93 for whole D-39-TR. No problematic items were detected in the scale. The ICC for test-retest reliability was 0.91 (95% CI 0.91-0.94). The test-retest consistency for the total score was r = 0.94, p < 0.001. D-39-TR was explained by five factors. The ratio of explaining the total variance of these 5 factors was determined as 53.97%. SF-36 (r=-0.48, p < 0.001) and HbA1c values (r = 0.31, p < 0.001) were moderately correlated with total score of D-39-TR. A significant difference was found between QoL values of patients with poor and good glycemic control (p < 0.001). Conclusion: Turkish version of D-39 is a reliable and valid scale for measuring QoL in patients with type 2 diabetes.IMPLICATIONS FOR REHABILITATIONThe Turkish version of the Diabetes-39 (D-39) is a valid and reliable questionnaire and can be used in patients with type 2 diabetes.The Turkish version of the D-39 offers a useful tool for better identifying quality of life of patients with type 2 diabetes who are at risk for adverse outcomes.The Turkish version of the D-39 can be used to evaluate the effectiveness of attempts to increase quality of life in patients with type 2 diabetes.

    Effect of Telerehabilitation on Exercise Capacity, Cardiac Function and Physical Activity in a Patient with Systemic Arterial Hypertension: A Case Report
    (Hacettepe University, 31 Ocak 2025) Durukan, Beyza Nur; Jam, Farzin; Çırak, Yasemin; Ozan, Zeynep; Şener, Yusuf Ziya; Yaglı, Naciye Vardar
    Aim: The aim of this study was to investigate the effects of calisthenic-based aerobic exercise training applied via real-time telerehabilitation on cardiac functions, exercise capacity, physical activity and body composition in an adult patient with systemic hypertension. Methods: A 48-year-old female case is presented in this study. The hypertensive individual who applied to the Sorgun State Hospital Department of Cardiology was consulted for cardiac rehabilitation (CR). Since the patient did not have access to outpatient CR, the physical therapist decided to perform synchronous telerehabilitation. Before and at the end of the exercise training, exercise capacity was assessed with 6-minute stepper test and maximal stress test, physical activity level with the International Physical Activity Scale and smart watch, body composition with bioelectrical impedance analysis, and systolic and diastolic functions with echocardiography. The patient underwent submaximal exercise training via video conference for 24 sessions and real-time heart rate monitoring was performed with a smart watch during the exercise. Results: The patient (height: 155 cm, body mass index: 31.61 kg/m²) completed all 24 sessions (100%). No adverse events were observed during the exercise sessions. At the end of the exercise training, there were improvements in the patient’s systolic and diastolic functions as well as in 24-hour blood pressure monitoring. Moreover, there was a significant increase in predicted oxygen consumption and exercise capacity levels. In addition, positive changes were observed in the patient’s physical activity level and body composition. Discussion: Hypertension, a major cause of morbidity and mortality, can benefit from aerobic exercise training delivered via telerehabilitation, which has demonstrated significant improvements in cardiometabolic health. Given the high adherence rate, cost-effectiveness, and feasibility, cardiac telerehabilitation appears to be a promising intervention for managing hypertension in clinical practice.
