Article Citation - WoS: 6Citation - Scopus: 6Agreement Between Tele-Assessment and Face-To Assessment of 30-S Sit-To Test in Patients With Type 2 Diabetes Mellitus(Springer London Ltd, 2023) Aktan, Ridvan; Yilmaz, Hayriye; Demir, Ismail; Ozalevli, SevgiBackground The globalization of healthcare systems, and the aim to lower healthcare costs have all contributed to the growth of telehealth technology in recent years. However, before these systems are put into use, their efficacy should be verified. To the best of our knowledge, this is the first study focusing on the evaluation of functional exercise capacity using the 30-s sit-to-stand (30-s STS) test as a tele-assessment method in patients with type 2 diabetes mellitus (T2DM). Aims The purpose of the study is to investigate the level of agreement between tele-assessment and face-to-face assessment of 30-s STS test in patients with T2DM. Methods Fifty participants performed two times 30-s STS tests separated by 1 h: a face-to-face and an Internet-connected video call examination (tele-assessment). Two physiotherapists conduct these evaluations; each was blinded to the other. The order of the evaluations was designated at random for each participant and physiotherapist. Results There was a good level of agreement between tele-assessment and face-to-face assessment of the 30-s STS test (mean differences = 0.20 +/- 0.88, limits of agreement =1.93 to - 1.53). Excellent interrater reliability was found for scores of the 30-s STS test [ICC = 0.93 (95% CI: 0.88; 0.96)]. In addition, all before and after test parameters show that there was a very good interrater reliability (rho >= 0.75). Conclusions This study shows a good level of agreement between tele-assessment and face-to-face assessment of the 30-s STS test. Our study's findings indicate that tele-assessment is a potential application to determine the level of physical capacity remotely in patients with T2DM.Article Citation - WoS: 15Citation - Scopus: 18Effects of Supervised Exercise Program and Home Exercise Program in Patients With Systemic Sclerosis: a Randomized Controlled Trial(Wiley, 2021) Yakut, Hazal; Ozalevli, Sevgi; Aktan, Ridvan; Alpaydin, Aylin Ozgen; Birlik, Ahmet Merih; Can, GercekAim To compare the effects of supervised exercise and home exercise program in patients with systemic sclerosis (SSc). Methods Thirty-seven SSc patients were included. Patients with SSc were allocated into 2 groups as supervised and home exercise. Breathing, aerobic and resistance exercises were performed with a physiotherapist for 12 weeks in the supervised exercise group. Breathing, posture and aerobic exercises were given to the home exercise group as a home program for 12 weeks. All patients were assessed at baseline and 12 weeks later in terms of functional capacity, pulmonary functions, respiratory-peripheral muscle strength, dyspnea severity, health-related quality of life (HRQoL) and fatigue level. Results Significant improvements were observed in the functional capacity, measured by 6 minute walking test in the supervised exercise group (before = 376.21 +/- 65.50, after = 518.78 +/- 75.84 m) and home exercise group (before = 384.44 +/- 68.14, after = 432.7 +/- 70.8 m; (P < .05). Respiratory-peripheral muscle strength (with the exception of inspiratory muscle strength and upper limb strength in the home exercise group) and HRQoL were significantly increased and fatigue level was significantly decreased in the supervised exercise and home exercise groups (P < .05). However, pulmonary functions and dyspnea severity were significantly improved only in the supervised exercise group (P < .05). The supervised exercise program was found superior to the home exercise program for change in all parameters (P < .05). Conclusion This study suggests that exercise interventions should be applied in addition to the medical treatments of patients with SSc as supervised and home exercise programs play an important role in the functionality and health status of these patients.Article Citation - WoS: 1Citation - Scopus: 1Cultural Influences on Choosing to Move More and Sit Less(W.B. Saunders, 2025) Aktan, Ridvan; Hall, Grenita; Ozemek, CemalLow levels of physical activity (PA) and prolonged periods of sedentary time significantly increase the risk of developing non-communicable diseases. Individuals who minimally increase their PA levels can experience significant reductions in risk of morbidity and mortality. Despite regular public messaging cycles and PA promotional campaigns highlighting these observations, the number of individuals meeting the PA recommendations has been underwhelming and stagnant for decades. Numerous studies have identified prominent barriers to becoming and staying physically active, in addition to a person's or people's cultural beliefs. Yet exercise professionals and other allied healthcare professionals may not consider one's cultural experiences when promoting PA. Recognizing the impact of culture on PA, whether it is positive or negative, can facilitate culturally sensitive discussions with individuals or groups and customizing PA recommendations in a way that facilitates its adoption. Accordingly, this paper aims to review relevant studies and examples of how culture can influence PA behaviors, as well as provide considerations for exercise professionals and allied healthcare providers to take when promoting PA in diverse populations.Conference Object Effects of High-Intensity Inspiratory Muscle Training as a Pre-Cardiac Rehabilitation Intervention on Cardiovascular Function in Patients With Heart Disease: a Pilot Study(Lippincott Williams & Wilkins, 2024) Aktan, Ridvan; Severin, Richard; Ozemek, CemalArticle Citation - WoS: 2Factors Affecting the Severity of Fatigue in Male Patients With Chronic Obstructive Pulmonary Disease(Ediciones Doyma S A, 2021) Alpaydin, A. O.; Aktan, R.; Keles, E.; Ozalevli, S.Background and objectives: Fatigue, the second most common symptom after dyspnea in patients with chronic obstructive pulmonary disease, impairs functional capacity and quality of life. This study aims to predict the factors that affect fatigue severity and investigate the effects of fatigue in patients with chronic obstructive pulmonary disease. Methods: Data were collected to assess demographic and clinical characteristics, cigarette consumption, fatigue severity (Fatigue Severity Scale), dyspnea severity (Medical Research Council Dyspnea Scale), level of physical activity (International Physical Activity Questionnaire-Short Form), and health-related quality of life (36-Item Short Form Health Survey). Results: A total of 64 male chronic obstructive pulmonary disease patients were evaluated (mean age 61.1 +/- 4.7 years, mean Fatigue Severity Scale score 39.8 +/- 14.4). The result of the linear regression model was significant and explained 84% of the variance in fatigue severity (Adjusted R-squared = 0.84, F=29.48, df = 60, p < .001). It showed that the Medical Research Council Dyspnea Scale score (beta= .40), cigarette consumption (beta = .35), and physical activity level (beta= -.37) were significantly correlated with the severity of fatigue (p < .001 for all) and that they independently contributed to the prediction of severity of fatigue. Conclusion: Dyspnea, cigarette consumption, and physical activity level affect fatigue severity. Additionally, physical activity levet, pulmonary function, and health-related quality of life were also associated with fatigue. These findings support the assertion that it is important to measure fatigue and the factors that affect its severity.

Methods: A questionnaire was sent via e-mail to the 135 MS patients, who clinically diagnosed with MS and EDSS score was determined.Perceived dyspnea was assessed by the mMRC scale.The severity of dyspnea and fatigue perceived during rest and effort was assessed by the mBORG scale.Functional levels of the patients were assessed by asking the average daily walking distance and the average sitting time daily. Results: The mean EDSS score of the smoker and the non-smoker group were 2.85 +/- 0.75, 2.96 +/- 1.03 respectively(p = 0.48).There was no statistically difference found between groups in terms of age,height,weight,BMI,gender,EDSS scores(p > 0.05).The rate of cough, sputum and severity of perceived dyspnea was statistically higher in the smoker group(p < 0.05).The mean walking distance daily of the smokers was statistically lower (p < 0.001). The smoker group had a high level of sedanter lifestyle(p < 0.05). Conclusion: It has been proven that smoking increases respiratory problems even in MS patients with a good EDSS score.Moreover, these problems lead to a further reduction in the functional levels of the patients, in addition to the disease progression.Article Citation - WoS: 3The Effects of Respiratory Muscle Functions on Trunk Muscle Endurance in Healthy Young Adults(Dokuz Eylul Univ Inst Health Sciences, 2023) Aktan, Özge Ocaker; Aktan, Rıdvan; Yakut, Hazal; Yakut, Hazal; Ozalevli, Sevgi; Kara, BilgePurpose: Respiratory muscles play a dual role in breathing and trunk stability during activities. The relationship between respiratory muscle functions and trunk stability has not yet been clarified. The aim of the study was to examine the effects of respiratory muscle functions on trunk muscle endurance in healthy young adults. Methods: McGill's trunk muscle endurance tests, which consist of trunk flexion endurance test (FE), Sorensen test (ST) and Side Bridge test (SB), were used to evaluate the participants' trunk muscle endurance. Respiratory muscle strength was evaluated by measuring intraoral maximal inspiratory and expiratory pressures using an intraoral pressure meter device. The respiratory muscle endurance test was performed with the incremental threshold load protocol using a threshold IMT device. Results: A total of 51 healthy young adults, with a mean age of 21.8 ± 3.2 years, were evaluated. The results of the linear regression models were significantly explained 46% of the variance in the SB and 38% in the FE, (for SB Adj R2=0.46, F=21.40, p< 0.001 and for FE Adj R2=0.38, F=15.65, p< 0.001). Respiratory muscle endurance contributed 30% to the endurance of the trunk flexor muscles, while respiratory muscle strength contributed only 8%. Similarly, respiratory muscle endurance contributed 38% to the endurance of the trunk lateral flexor muscles, while respiratory muscle strength contributed only 8%. Conclusion: Although respiratory muscle strength and respiratory muscle endurance were independent contributors to trunk muscle endurance, respiratory muscle endurance more affected trunk muscle endurance than respiratory muscle strength in healthy young adults.Conference Object The Effects of Respiratory Muscle Functions on Trunk Muscle Endurance in Healthy Young Adults [conference Object](European Respiratory Soc Journals Ltd, 2021) Aktan, Ozge Ocaker; Aktan, Ridvan; Yakut, Hazal; Ozalevli, Sevgi; Kara, Bilge[Abstract Not Available]Article Citation - WoS: 8Citation - Scopus: 10Effects of Home-Based Telerehabilitation-Assisted Inspiratory Muscle Training in Patients With Idiopathic Pulmonary Fibrosis: a Randomized Controlled Trial(Wiley, 2024) Aktan, Rıdvan; Tertemiz, Kemal Can; Yiğit, Salih; Özalevli, Sevgi; Özgen Alpaydın, Aylin; Uçan, Eyup SabriBackground and Objective: There are few studies that have used inspiratory muscle training (IMT) as an intervention for patients with isolated idiopathic pulmonary fibrosis (IPF). This study aimed to investigate and interpret the effects of home-based telerehabilitation-assisted IMT in patients with IPF. Methods: Twenty-eight participants with IPF took part in the study. Lung function tests, functional exercise capacity by 6-min walk distance (6MWD), dyspnoea perception by modified medical research council dyspnoea scale (mMRC), and inspiratory muscle strength by maximal inspiratory pressure (MIP) were assessed. IMT was performed twice a day, 7 days/week, for 8 weeks. The intervention group (n = 14) performed IMT at 50% of their baseline MIP while the control group (n = 14) performed IMT without applied resistance. Loading intensity was progressed by keeping the load at 4-6 on a modified Borg scale for the highest tolerable perceived respiratory effort for each patient. Results: Dyspnoea based on mMRC score (p < 0.001, eta(2) effect size = 0.48) significantly decreased within the intervention group compared with the control group. There were significant increases in the intervention group compared to the control group based on 6MWD (p < 0.001, eta(2) effect size = 0.43), MIP (p = 0.006, eta(2) effect size = 0.25) and MIP % predicted (p = 0.008, eta(2) effect size = 0.25). Conclusion: The findings of this study suggest that an 8-week home-based telerehabilitation-assisted IMT intervention produced improvements in inspiratory muscle strength, leading to improvements in functional exercise capacity and dyspnoea.Conference Object Should Maximal Mid-Expiratory Flow (mmef) Be Considered More in Copd?(European Respiratory Soc Journals Ltd, 2020) Aktan, Ridvan; Ozalevli, Sevgi; Alpaydin, Aylin Ozgen[Abstract Not Available]
