Publication Open Access The effect of different body mass index levels on static and dynamic postural balance performance in adults(2023-01-01) TİMURTAŞ, EREN; SELÇUK, HALİT; DEMİRBÜKEN, İLKŞAN; POLAT, MİNE GÜLDEN; TİMURTAŞ E., SELÇUK H., Canoz E. U., Kortelli O. S., DEMİRBÜKEN İ., POLAT M. G.Purpose: It was aimed to estimate the static and dynamic postural balance performance in adults with different Body Mass Index (BMI) levels. Material and Methods: The study was conducted in Üsküdar Diabetes and Obesity Treatment Center between September and October 2021. Participants were divided into 5 groups according to BMI scores: normal-weight, overweight, 1st degree obese, 2nd degree obese, and 3rd degree obese. In addition, participants' static and dynamic balance performance were assessed by the Limits of Stability (LOS) and modified Clinical Test of Sensory Integration of Balance (m-CTSIB) tests. Results: For LOS parameters, there was a significant difference between groups in reaction time scores only for the backward direction (p<0.05). The endpoint and maximum excursion measurements except for the backward and directional control measurements except for the back and right were significantly different between groups, with the worst scores for 3rd degree obese group (p<0.05). For the m-CTSIB test, there was a significant difference between groups in all parameters except the eyes open condition on foam surface (p<0.05). Conclusion: The 3rd degree obese individuals are the most affected subgroup in dynamic balance. We recommended that rehabilitation and fall prevention programs primarily focus on 3rd degree obese individuals. Keywords: Limits of stability test, modified clinical test of sensory integration of balance, postural balance, body mass indexPublication Open Access An Investigation of the Effects of Holographic Wristbands on Strength, Balance and Flexibility - a Double-Blind Placebo Controlled Study(SOC PHYSICAL THERAPY SCIENCE, 2012) ÖZGÜL, BAHAR; Sari, Zubeyir; Kablan, Nilufer; Ozgul, Bahar; Aydogdu, Onur; Timurtas, Eren; Tutuncuoglu, Fatih; Yurdalan, Saadet Ufuk; Polat, Mine Gulden[Purpose] This study investigated the effects of holographic wristbands on strength, balance and flexibility. [Subjects and Methods] The study included 43 healthy university students, 15 females (34.88%) and 28 males (65.12%), attending the Department of Physiotherapy and Rehabilitation at Marmara University. The age of the participants ranged from 19 to 27 (mean age 21.2 +/- 1.7 years). Strength, balance with eyes open, balance with eyes closed and flexibility were evaluated under four different conditions of wearing holographic EFX (R), PWX (R) and placebo wristbands, and no wristband. [Results] In evaluations of strength, balance with eyes are open, balance with eyes closed and flexibility, a significant difference was observed in favor of the placebo wristband compared to the PWX (R) wristband. For the other tests, holographic wristbands had no effect on strength, flexibility or balance with eyes closed. [Conclusion] It was concluded that holographic wristbands, which are marketed asergogenic aids, have no effect on strength, balance or flexibility.Publication Open Access A mobile application platform to increase physical activity in individuals with type 2 diabetes during the coronavirus (covid-19) pandemic(2022-09-01) TİMURTAŞ, EREN; POLAT, MİNE GÜLDEN; Timurtaş E., Cinar E., Karabacak N., Sertbaş Y., Polat M. G.Introduction: Mobile health applications for individuals with type 2 diabetes (T2DM) have the potential to improve physical activity (PA) during the coronavirus (COVID-19) pandemic; yet, there is a need to identify the content of a mobile application (app) in the light of conceptual framework and the delivery features to increase the usability of the app. The aim of this study is to improve the mobile application based on a framework that conceptually determines the needs of individuals with T2DM. At the same time, it is to determine the presentation features of the application to increase its usability for individuals and health professionals using it. Methods: The content and delivery features of a PA app were determined using the Delphi method considering the dia- betes core sets of the international classification of the functioning framework, including experts in the area of T2DM for the app\"s content and heterogeneous participants for the delivery features of the app. A mobile application was created according to the data obtained by this method after the application was created by this way. Results: Delphi experts suggested 64 ideas for the content of the app, of which 46 reached sufficient agreement (72.5–100%). In the second step, participants generated 27 ideas, yet, the consensus was reached on 12 delivery features (70–100%). The application was created by transforming these ideas into app content. Discussion and Conclusion: This study addressed the content-related limitations and usability challenges in the pre-existing studies. During the lockdown, the developed PA app can be implemented using different mobile devices.Publication Metadata only Obez bireylerde farklı egzersiz eğitimlerinin yürütücü fonksiyonlar üzerine etkisi: Pilot çalışma(2023-08-30) KARAKOÇ, ZEHRA BETÜL; DEMİRBÜKEN, İLKŞAN; TİMURTAŞ, EREN; Karakoç Z. B., Demirbüken I., Timurtaş E., Sertbaş Y.Obez Bireylerde Farklı Egzersiz Eğitimlerinin Yürütücü Fonksiyonlar Üzerine Etkisi: Pilot ÇalışmaÖzet: Çalışmamızın amacı, obezitenin yönetiminde bilimsel araştırmalar sonucu kullanılması önerilen egzersiz eğitimlerinin yürütücü fonksiyonlar üzerindeki etkilerinin karşılaştırılmasıydı. Çalışmamıza Üsküdar Diyabet ve Obezite Merkezi’ne doktor tarafından egzersiz uygulaması için yönlendirilen dahil edilme kriterlerini sağlayan 11 obez olgu dahil edildi. İnhibitör kontrol, çalışma belleği ve kognitif fleksibiliteyi değerlendirmek için sırasıyla Stroop Renk ve Kelime Testi, 2-back Testi ve İz Sürme Testi A-B (İST A-B) kullanıldı. Değerlendirmede için sırasıyla, için, için kullanıldı. Egzersiz gruplarından biri yüksek şiddetli (kombine yüksek şiddet, n=5), diğeri ise orta şiddetli (kombine orta şiddet, n=6) aerobik ve dirençli egzersizlerden oluştu. Aerobik egzersizler karvonen yöntemine göre yüksek şiddet için %70, orta şiddet için %60 şiddetinde koşu bandında gerçekleştirildi. Dirençli egzersizler 1 maksimum tekrara göre yüksek şiddetli grupta %70, orta şiddetli grupta %60 oranında direnç makinelerinde gerçekleştirildi. Aerobik egzersizler ilk 4 hafta, haftada 3 gün; sonraki 4 hafta haftada 5 gün yapıldı. Dirençli egzersizler haftada 2 gün, her egzersiz 2 set olacak şekilde gerçekleştirildi. Stroop, 2-back Testi ve İST-B değerleri egzersiz sonrası her iki grupta da değişkenlik göstermezken İST-A bölümü orta şiddet egzersiz grubunda anlamlı bir gelişme kaydedildi (p=0.046). Egzersiz öncesi ve sonrası gruplar arası karşılaştırmalarda her iki grup da benzerlik gösterdi (p>0.05). Kombine orta şiddet egzersiz programı, işlem hızında artışa neden olarak yürütücü fonksiyonlarda gelişme sağladı. Bu çalışmanın sonuçları, sağlıklı deneklerin bilişsel performansı için optimal olan orta yoğunlukta egzersiz eğitiminin obez denekler için de geçerli olduğunu desteklemektedir. Çalışmamızdaki yüksek şiddet egzersiz grubunda kognitif performans kötüleşmese de bu sonuçların inverted-U hipotezi ile açıklanabileceğini düşünmekteyiz. Anahtar Kelimeler: Obezite, Yürütücü Fonksiyonlar, Egzersiz The Effect of Dıfferent Exercıse Traınıngs On Executıve Functıons in Obse Indıvıduals: Pılot Study Abstract: The aim of our study was to compare the effects of exercise training, which is recommended to be used in the management of obesity as a result of scientific research, on executive functions. Our study included 11 obese patients who were referred to Üsküdar Diabetes and Obesity Center for exercise practice. Stroop Color and Vocabulary Test, 2-back Test and Trail Making Test A-B (TMT A-B) were used to assess inhibitory control, working memory and cognitive flexibility, respectively. One of the exercise groups consisted of high-intensity (combined high-intensity, n=5), and the other consisted of moderate-intensity (combined moderate-intensity, n=6) aerobic and resistance exercises. Aerobic 13th UTSAK, 26-27 August, Ankara | 101 exercises were performed on the treadmill at an intensity of 70% for high intensity and 60% for moderate intensity, according to the Karvonen method. Resistance exercises were performed on resistance machines at a rate of 70% in the high-intensity group and 60% in the moderate-intensity group, according to 1 maximum repetition. Aerobic exercises were performed 3 days a week for the first 4 weeks, and 5 days a week for the next 4 weeks. Resistance exercises were performed 2 days a week, with 2 sets of each exercise. Stroop, 2-back Test, and TMT-B values did not show any difference after exercise in both groups, while the TMT-A significantly increase in the moderate intensity exercise group (p=0.046). In comparisons between groups before and after exercise, both groups showed similarity (p>0.05). Combined moderate-intensity exercise program led to an increase in processing speed and improved executive functions. The results of this study support that moderate-intensity exercise training, which is optimal for the cognitive performance of healthy subjects, is also optimal for obese subjects. Although cognitive performance did not worsen in the high-intensity exercise group in our study, we think that these results can be explained by the inverted-U hypothesis.

Although there are some mobile applications in use, validated mobile tools for accurate postural assessment are still warranted. Aims This study aimed to develop Fizyoprint mobile application tool to assess standing posture and investigate the validity and reliability of the application in young adults. Methods A convenience sample of 20 young adults (12 men and 8 women with a mean age of 21.3 +/- 2.2 years) and 2 physiotherapists as raters participated in the study. The participant's digital images were obtained from the anterior, posterior, and right lateral sides. The raters selected the anatomic reference points by using digital markers in the app screen, and the Fizyoprint application, with Turkish language option, calculated a total of 26 posture variables, including 11 distance and 15 angle variables. Each participant was assessed twice (1-week interval) by 2 raters with Fizyoprint. Inter- and intra-rater reliabilities were estimated using the intraclass correlation coefficient. The BioTonix (TM) posture analysis system was used for validation. Results A total of 80.7% (21 variables) indicated acceptable to excellent intra-rater reliability results. A total of 57.7% (15 variables) were found to be acceptable to excellent for inter-rater measurements. The results confirmed the validity of the Fizyoprint application for testing the standing posture. Conclusions Fizyoprint application is a new, valid, free mobile tool with acceptable concordance with BioTonix (TM) postural analysis system for assessing standing posture. Further studies are warranted to test the current application in different populations and musculoskeletal conditions.Publication Open Access Covid-19 pandemisinde fizyoterapistlerin telerehabilitasyon uygulamaları bariyer ve fasilitatörlerinin incelenmesi(2022-08-01) TİMURTAŞ, EREN; POLAT, MİNE GÜLDEN; Timurtaş E., Polat M.

G.Publication Open Access Usability of Mobile Health Application for Individuals with Type 2 Diabetes Mellitus and Clinicians(MARMARA UNIV, INST HEALTH SCIENCES, 2020-03-31) TİMURTAŞ, EREN; Timurtas, Eren; Polat, Mine GuldenObjective: Usability of technological devices is an important and relevant construct as mobile technologies are increasingly used to deliver healthcare products. Most accessible devices are smartphone and smartwatch but information on their usability is scarce. The aim of this study is to compare the usability of smartphone and smartwatch devices in delivering an exercise platform to individuals with Type 2 Diabetes Mellitus (T2DM) among two focus groups: individuals with T2DM and clinicians. Methods: A total of 40 individuals with T2DM (focus group 1) and 20 clinicians (focus group 2) were recruited to use the platforms one week. Each focus group was randomly divided into: smartphone and smartwatch groups. Each participant was provided with a practice trial for a week before data collection. Usability of both devices was measured with System Usability Scale (SUS). Student t-test was used to compare the total and subscale scores of SUS between two devices in each focus group. Results: In focus group 1 and 2, the mean total scores of SUS were slightly higher in smartphone group (88,75 +/- 9,34 and 86,75 +/- 8,68 ) than smartwatch group (87,87 +/- 7.56 and 82,35 +/- 6,59) respectively. When compared to individual items, three items were statistically significant in focus group 1 and one in focus group 2 (p <= 0.05). Conclusion:This study demonstrates a high usability (SUS score>80,8) for both smartphone and smartwatch devices in individuals with T2DM and clinicians. When compared between devices for two groups, exercise platform delivered through smartphone performed better on usability than smartwatch for both individuals with T2DM and clinicians.
