(Springer London Ltd, 2023) Aktan, Ridvan; Yilmaz, Hayriye; Demir, Ismail; Ozalevli, Sevgi
Background 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.

Clinical Outcomes of Male Subjects With Moderate Copd Based on Maximum Mid-Expiratory Flow
(Daedalus Enterprises Inc, 2021) Aktan, Ridvan; Ozalevli, Sevgi; Alpaydin, Aylin Ozgen
BACKGROUND: Although FEV1 and FEV1/NVC are accepted as standard parameters in treatment follow-up, these parameters have a limited ability to predict clinical outcomes in patients with COPD. However, small airways dysfunction, which is determined by maximum mid-expiratory flow, is variable in the same stage of patients with COPD, even if their FEV1 and FEV1/FVC are similar. The aim of this study was to compare pulmonary function, the severity of perceived dyspnea, the severity of fatigue, physical activity level, and health-related quality of life based on the severity of small airways dysfunction in male subjects with moderate COPD. METHODS: The study consisted of 96 subjects with moderate COPD. Pulmonary function tests, the distance achieved on the 6-min walk test, the modified Medical Research Council Dyspnea Scale, the International Physical Activity Questionnaire - short form, the Fatigue Severity Scale, the St George Respiratory Questionnaire, and Short Form 36 questionnaire were evaluated in all subjects. After calculating the mean percent of predicted maximum mid-expiratory flow for the entire sample, subjects were divided into 2 groups: below average (Group 1, n = 54 subjects) and above average (Group 2, n = 42 subjects). RESULTS: There were no differences between the groups in age, body mass index, cigarette consumption, percent of predicted FEV1, and FEV1/FVC (P = .55, .61, .19, .09, and .15, respectively). Scores from the Fatigue Severity Scale and the modified Medical Research Council dyspnea scale were significantly higher in Group 1 (P = .003 and P = .002, respectively); in addition, results from the 6-min walk test and the International Physical Activity Questionnaire - short form scores were significantly lower (P = .001 and P < .001, respectively). CONCLUSIONS: Increased small airways dysfunction led to increased perception of dyspnea and fatigue, as well as poor exercise capacity and health-related quality of life in male subjects with COPD. We suggest that it may be useful to consider the maximum mid-expiratory flow in addition to FEV1 and FEV1/FVC in the treatment and follow-up of male patients with moderate COPD.
Comparison of Pulmonary Function, Respiratory Symptoms, Functional Level, and Health-Related Quality of Life in Patients With Systemic Sclerosis According To Smoking Status
(Taylor & Francis Inc, 2022) Yakut, Hazal; Ozalevli, Sevgi; Aktan, Ridvan; Erez, Yesim; Birlik, Merih
Background Patients with systemic sclerosis (SSc) are at high risk for pulmonary and vascular complications. Smoking is an important risk factor for respiratory symptoms and vascular complications of many diseases in the general population. However, studies on the role of smoking in SSc are insufficient. Aims This study aimed to compare pulmonary function, respiratory symptoms, functional level, and health-related quality of life (HRQoL) in patients with SSc according to smoking status and to assess the correlation between cigarette consumption and these parameters in patients with SSc. Methods Seventy-two patients with SSc (smoker group; n = 35 or nonsmoker group; n = 37) were included. The pulmonary function test was measured with a spirometer. Respiratory symptoms were questioned and the perceived severity of dyspnea and fatigue was evaluated. The functional levels were determined by questioning the patients' average daily walking distance, exercise habits, and daily sedentary time. HRQoL was assessed by Scleroderma Health Assessment Questionnaire. Results The rate of respiratory symptoms including dyspnea, cough, and sputum were higher in the smoker group (p .001, p = .041, and p .001, respectively). Also, the perceived severity of dyspnea and fatigue was higher in the smoker group (p < .05). The mean daily walking distance, exercise habits, and overall HRQoL were lower (p = .004, p = .002, and p = .034, respectively) and the sedentary time and vascular complications were higher (p .001 and p = .038, respectively) in the smoker group. However, there was no significant difference between the two groups in terms of the pulmonary function test (p > .05). There was a weak to moderate correlation between cigarette consumption and respiratory symptoms, dyspnea and fatigue severity, functional level, and HRQoL in the smoker group (0.001 <= p <= .024). Conclusions Smoking may increase respiratory symptoms and vascular complications and decrease the functional level and HRQoL in patients with SSc. To maintain functional independence in patients with SSc, awareness of the harms of smoking should be increased and smoking cessation should be encouraged, along with physiotherapy and rehabilitation programs including exercise and physical activity recommendations.

Comparison of Pulmonary Functions, Physical Activity Level and Quality of Life in Obese and Pre-Obese Individuals
(Aves, 2017) Aktan, Ridvan; Ozalevli, Sevgi
Objective: There are studies regarding pulmonary functions of obese individuals in literature; however, there is insufficient data regarding pre-obese individuals. This study aimed to compare the pulmonary functions, physical activity levels, and health-related quality of life (HRQOL) of obese and pre-obese individuals. Methods: The characteristics of 62 subjects participating in the study were recorded All subjects were evaluated using pulmonary function tests (PFT), short form-36 health survey (SF-36), obesity and weight loss quality of life measure (OWLQOL), international physical activity questionnaires (IPAQ), and modified medical research council (mMRC) scale. Results: The severity of perceived dyspnea in obese subjects was significantly higher than that in pre-obese subjects. The PFT parameters (FVC, FEV 1, PEF, FEF 25-75, FEF 25-75 %, MVV, and MVV%) were significantly lower in obese subjects. Although individuals in both groups were inactive, the inactivity levels in obese subjects were significantly higher. HRQOL scores were significantly lower in obese individuals. The body mass index (BMI) was significantly correlated with dyspnea severity, SF-36 subscores, OWLQOL scores, and PFT parameters. Conclusion: While an increasing BMI has an adverse effect on the pulmonary functions of pre-obese individuals, increased BMI coupled with reduced pulmonary functions causes a decrease in the physical activity levels and reduces HRQOL of obese individuals.
Demans Hastalarının Birincil Aile Bakıcılarının Sağlığı Üzerine İkincil Bakım Verenin Etkileri: Fiziksel ve Psikolojik Yönlere Odaklanma
(2025) Yener, Görsev G.; Ozalevli, Sevgi; Yakut, Hazal; Felekoğlu, Elvan
Amaç: Dünya genelinde demans hastası sayısı artmakta ve hastalığın erken dönemlerinden itibaren bakım verenlere ihtiyaç duyulmaktadır. Ancak, birincil bakım verenin yanında ikincil bir bakım verenin bulunmasının birincil bakım verenin fiziksel ve psikolojik sağlığı üzerindeki etkisi net değildir. Bu çalışma, ikincil bakım veren bulunan ve bulunmayan birincil bakım verenlerin fiziksel ve psikolojik parametreler açısından karşılaştırılmasını amaçlamıştır. Gereç ve Yöntem: Bu kesitsel çalışma, İzmir’de bir üniversite hastanesinin nöroloji polikliniklerinden alınan 61 demans hastasının birincil aile bakıcısını içermektedir. Katılımcılar, bakım verme düzenlemelerine göre iki gruba ayrılmıştır: tek başına bakım verenler (n=26; %42,6) ve ikincil bir bakıcıyla birlikte bakım verenler (n=35; %57,4). Fiziksel sağlık, Nordic Kas-İskelet Sistemi Anketi (kas-iskelet sistemi bozuklukları), Uluslararası Fiziksel Aktivite Anketi (fiziksel aktivite) ve Yorgunluk Şiddeti Ölçeği (yorgunluk) kullanılarak değerlendirilmiştir. Psikolojik sağlık ise Dünya Sağlık Örgütü Yaşam Kalitesi Ölçeği-Kısa Formu ve Zarit Bakıcı Yükü Ölçeği ile değerlendirilmiştir. Bulgular: Gruplar arasında psikolojik ölçümler açısından anlamlı bir fark bulunmamıştır. Ancak, fiziksel sağlık açısından farklılıklar gözlemlenmiştir. İkincil bir bakıcısı olmayan bakıcılar, bakım verme görevleri nedeniyle günlerinin anlamlı derecede daha büyük bir bölümünü oturarak geçirmiştir (p=0,020). Ayrıca son yedi gün içinde omurga (p=0,05), üst ekstremiteler (p=0,046) ve alt ekstremitelerde (p=0,019) daha fazla kas-iskelet şikâyeti rapor edilmiştir. Sonuç: İkincil bir bakımverenin varlığı, demans hastalarına bakan birincil bakımverenlerin fiziksel sağlığıyla ilişkilidir; ancak psikolojik iyi oluş üzerinde anlamlı bir etkisi bulunmamaktadır. Bu bulgular, bakımverenlerin sağlıklarını koruyabilmeleri için fiziksel destek sağlanmasının gerekliliğini vurgulamaktadır. Özellikle bakımın kültürel olarak aile içinde yürütüldüğü toplumlarda, çok yönlü bakımveren destek programlarına duyulan ihtiyacı öne çıkarmaktadır.

(Elsevier Sci Ltd, 2018) Aktan, Ridvan; Ozalevli, Sevgi; Özakbaş, Serkan
Objective: The aim of the study was to investigate the effects of smoking on respiratory symptoms and functional levels by questioning use of cigarette in Multiple Sclerosis (MS) patients. 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.

(Dokuz Eylul Univ Inst Health Sciences, 2023) Aktan, Özge Ocaker; Aktan, Rıdvan; Yakut, Hazal; Yakut, Hazal; Ozalevli, Sevgi; Kara, Bilge
Purpose: 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.

(Wiley, 2021) Yakut, Hazal; Ozalevli, Sevgi; Aktan, Ridvan; Alpaydin, Aylin Ozgen; Birlik, Ahmet Merih; Can, Gercek
Aim 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.

Impact of Inspiratory Muscle Strength and Lung Function on Functional Exercise Capacity in Post-Myocardial Infarction Patients: A Cross-Sectional Study
(Galenos Publishing House, 2025) Aktan, Rıdvan; Ozalevli, Sevgi; Dursun, Huseyin; Aktan, Özge Ocaker
OBJECTIVE: This study aims to investigate the contribution of lung function and respiratory muscle strength in predicting functional exercise capacity in post-myocardial infarction (MI) subjects. MATERIAL AND METHODS: This cross-sectional study included 56 stable post-MI subjects. Lung function was assessed using a digital spirometer, and respiratory muscle strength was measured using an intraoral pressure meter. The 6-minute walk distance (6MWD) was conducted to assess functional exercise capacity. Correlations and multiple regression analyses were performed to evaluate predictors of 6MWD, considering demographic factors, lung function, and respiratory muscle strength. The Bland-Altman plot was used to investigate the agreement between observed and predicted 6MWDs. RESULTS: Significant positive correlations were found between 6MWD and forced vital capacity (FVC)%predicted (r = 0.528, P = 0.022) and maximum inspiratory pressure (MIP)%predicted (r = 0.640, P = 0.022). Age (r = -0.350, P = 0.008) and body mass index (BMI) (r= -0.561, P < 0.001) were negatively correlated with 6MWD. The best regression model included MIP%predicted (β = 0.332, P = 0.002), BMI (β = -0.264, P = 0.012), being male (β = 0.262, P = 0.003), age (β = -0.210, P = 0.020), and FVC%predicted (β = 0.219, P = 0.026) as significant unique contributors. The final multiple linear regression model was significant [F (5, 50) = 19.08, P < 0.001] and explained 65.6% of the variance (R2 = 0.656) in the 6MWD. CONCLUSION: Lung function and respiratory muscle strength significantly contribute to functional exercise capacity in post-MI. This study emphasizes the importance of comprehensive respiratory function assessments in rehabilitation strategies to improve exercise capacity in patients with post-MI.

KOAH Hastalarında Vücut Ağırlığı-Yürüme Mesafesinin Sağlıkla İlişkili Yaşam Kalitesi İle İlişkisi: 6 Dakikalık Yürüme Mesafesi İle Karşılaştırmalı Bir Çalışma
(2025) Aktan, Rıdvan; Alpaydin, Aylin Ozgen; Ozalevli, Sevgi
Amaç: Bu çalışmanın amacı, geliştirilmiş bir sonuç ölçütü olarak 6 dakika yürüme testi mesafesi-vücut ağırlığı çarpımı (yani 6 dakikalık yürüme işi-6DK-İŞİ) ile sağlıkla ilişkili yaşam kalitesi arasındaki ilişkiyi incelemek ve bu ilişkiyi 6 dakika yürüme testi mesafesi ile karşılaştırmaktı. Yöntem: Bu retrospektif kesitsel çalışmaya orta-ağır KOAH'lı toplam 81 hasta (ortalama yaş: 61.0±4.6 yıl) dahil edildi. Çalışma Ocak 2025 ile Mart 2025 tarihleri arasında gerçekleştirildi. Hastaların klinik özellikleri, akciğer fonksiyon testleri, 6 dakika yürüme testi mesafeleri ve Saint George Solunum Anketi (SGRQ) ile ölçülen sağlıkla ilişkili yaşam kalitesi sonuçları kaydedildi. 6DK-İŞİ, 6 dakika yürüme testi mesafesi ve vücut ağırlığının birbiriyle çarpımı olarak hesaplandı ve kg.metre (kg.m) olarak kaydedildi. SGRQ ile 6 dakika yürüme testi mesafesi ve 6DK-İŞİ arasındaki korelasyon katsayıları ve basit doğrusal regresyonlar değerlendirildi. Bulgular: Hastaların ortalama 6 dakika yürüme testi mesafesi ve 6DK- İŞİ sırasıyla 441.5±83.3 m ve 33176.2±9865.8 kg.m idi. 6DK-İŞİ SGRQ alt alanlarıyla (r=−.582 ile −.641 arasında, p<.001) 6 dakika yürüme testi mesafesine (r =−.381 ile −.455 arasında, p<.001) kıyasla daha güçlü korelasyonlar gösterdi. Ayrıca basit doğrusal regresyon analizine göre, SGRQ toplam puanı ile 6 dakika yürüme testi mesafesi arasındaki belirleme katsayısı (R2) .207 iken 6DK-İŞİ ise .411 idi. Sonuç: Bulgularımız 6 dakika yürüme testinde kat edilen basit mesafe yerine 6DK-İŞİ’nin kullanılmasının, yaşam kalitesi ile ilişkisi nedeniyle orta-ağır KOAH'lı hastalarda daha avantajlı olduğunu göstermektedir. Bu nedenle 6DK-İŞİ orta-ağır KOAH'lı hastalarda fonksiyonel kapasiteyi tahmin etmek için daha etkili bir sonuç parametresi olabilir. Daha geniş, daha çeşitli popülasyonlarla ve uzunlamasına tasarımlarlı gelecek çalışmalara ihtiyaç vardır.

Validation of the Rapid Assessment of Physical Activity Questionnaire in Older Patients With Chronic Obstructive Pulmonary Disease
(Dokuz Eylul Univ Inst Health Sciences, 2021) Aktan, Ridvan; Ozalevli, Sevgi; Yalcinkaya, Gamze; Alpaydin, Aylin Ozgen; Sevinc, Can
Purpose: There are not many questionnaires that have proven validity and reliability in evaluating the level of physical activity in older patients with chronic obstructive pulmonary disease (COPD). In clinical and scientific studies, it is important to quickly determine the physical activity level of patients in terms of time management. The aim of the study was to examine the validity of the rapid assessment of physical activity (RAPA) questionnaire in older patients with COPD. Methods: A total of 105 older patients with COPD surveyed the short form of the International Physical Activity Questionnaire (IPAQ-SF) and after 2 weeks RAPA questionnaire as well. The IPAQ-SF was accepted as the gold standard for physical activity assessment in COPD. Furthermore, patients were assessed for a 6-min walking test (6MWT) and perceived dyspnea (with modified medical research dyspnea scale (mMRC)). Correlation coefficients (r) was used for the relationship between RAPA and IPAQ-SF. Results: There were significant positive correlations between RAPA and IPAQ-SF total score (r = 0.968, p<0.001), 6MWT (r = 0.626, p<0.001), in addition to significant negative correlation between the RAPA and mMRC scores (r = -0.454, p<0.001). The RAPA showed good sensitivity (87.5%) and a specificity (100%) value. Positive and negative predictive values of the RAPA were 100% and 96.4% respectively. Conclusion: This study showed the RAPA was an easy-to-use, valid, and reliable questionnaire to measure physical activity levels in older patients with COPD.
