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 Investigation of the reasons for the employee turnover of parkinson's patients(2022-01-01) OĞUZ, SEMRA; POLAT, MİNE GÜLDEN; ERTÜRK UZUNOĞLU G., OĞUZ S., POLAT M. G., ERTAN F. S.Purpose: It is known that early retirement has been increasing for patients with Parkinson\"s disease. The data on the factors that cause early retirement in this patient population is limited. The objective of this study is to analyze the effects of Parkinson\"s disease that cause early retirement.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 Open Access Does kinesiophobia limit physical activity and quality of life in asthmatic patients(2022-09-01) KARACA, SEDA; POLAT, MİNE GÜLDEN; YILDIZ ÖZER, AYSEL; OĞUZ, SEMRA; Yıldız Özer A., Karaca S., Şenocak E., Oğuz S., Polat M. G.Kinesiophobia has been studied in musculoskeletal and neurological diseases. The aim of this descriptive study was to assess the level of kinesiophobia in stable asthmatic patients, and to determine whether it is an obstacle to physical activity and quality of life. A total of 62 asthmatic patients and 50 healthy control subjects were assessed using the tampa kinesiophobia scale (TSK) for kinesiophobia, International Physical Activity Questionnaire-Short Form (IPAQ-SF) for physical activity levels, and Asthma Quality of Life Questionnaire (AQLQ) for quality of life. A high degree of kinesiophobia was determined in 54.8% of the asthmatic patients. The TSK scores were significantly higher (P < 0.001), and the AQLQ scores were lower in the asthma group than in the control group (P < 0.001). The IPAQ-SF level and AQLQ score were lower (P < 0.001 for both) in the asthmatic group with a high kinesiophobia score. The TSK score was significantly associated with IPAQ-SF score (r = -0.889; P < 0.001) and AQLQ score (r = -0.820; P < 0.001) in asthmatic patients. According to linear regression analysis, kinesiophobia explained 84.40% of QoL and physical activity. Patients with a stable asthma were observed to have a high level of kinesiophobia compared with healthy subjects. High kinesiophobia levels may increase the disease burden by negatively affecting participation in physical activity and quality of life. While developing asthma education programs for asthma patients, it should be remembered that even in the stable period, kinesiophobia can develop. Preventive and therapeutic programs should include precautions to improve quality of life and physical activity against the effects of kinesiophobia.Publication Open Access The effects of the hybrid telerehabilitation exercise program in inactive university students during COVID-19 pandemic - A randomized controlled study(2023-02-01) POLAT, MİNE GÜLDEN; YILDIZ ÖZER, AYSEL; Ozer A. Y., ŞENOCAK E., Aybey B. N., Tolmaci L., Surmeli S., Ozmen I., POLAT M. G.Background/Aim The need for alternative methods to prevent physical inactivity and related problems is increasing day by day due to the prevalence of physical inactivity among university students, especially in the pandemic. This study aimed to investigate the effects of a hybrid telerehabilitation exercise program on the physical inactivity, poor sleep quality and physio-mental negativities caused by the pandemic in university students. Materials and Methods The study was completed with sixty-three physically inactive students with poor sleep quality, divided into two groups. The physiotherapist made all assessments at baseline and after the 6-week for both groups. Assessments consisted of Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), Short Form-12 (SF-12), and International Physical Activity Questionnaire-Short Form (IPAQ-SF). While no exercise program was applied to the control group, one session synchronous exercise training and one session control education were given to the exercise group. After two synchronous training sessions, the exercise group asynchronously continued the exercise program including indoor walking, flexibility and strengthening exercises for 6 weeks. Results According to inter-groups analysis, PSQI (p=0.026), BDI (p=0.037), SF-12 Mental (p=0.007), and IPAQ-sitting (p=0.003) of the exercise group had significant differences compared to the control. Also, the exercise group\"s PSQI, BDI, SF-12, and IPAQ-sitting time were p0.05). Conclusion Hybrid telerehabilitation exercise programs are a valuable, simple, and practical tool to improve sleep quality, prevent inactivity, develop and protect mental health among university students. Encouraging physically inactive people to engage in such methods may be one of the primary preventive approach to prevent the future negative consequences.Publication Open Access The effect of 2 different dual-task balance training methods on balance and gait in older adults: a randomized controlled trial(2022-03-01) POLAT, MİNE GÜLDEN; OĞUZ, SEMRA; Yuzlu V., Oguz S., Timurtas E., Aykutoglu E., Polat M. G.Objective The purpose of this study was to compare the effects of integrated and consecutive cognitive dual-task balance training in older adults on balance, fear of falling, and gait performance. Methods Fifty-eight participants (age >65 years) were randomly assigned to an integrated dual-task training group (IDTT) (n = 29) and consecutive dual-task training group (CDTT) (n = 29). Balance exercises and cognitive tasks were performed simultaneously by the IDTT group and consecutively by the CDTT group for 8 weeks. Balance was assessed using the Berg Balance Scale as a primary outcome measure and the Timed \"Up & Go\" Test (TUG) (standard-cognitive), fear of falling was assessed using the Tinetti Falls Efficacy Scale, and gait speed was assessed using the 10-Meter Walk Test (10MWT) (under single-task and dual-task conditions). All tests were performed before and after the training. Results There was no difference in group-time interaction in the Berg Balance Scale, TUG-standard, 10MWT-single task, and 10MWT-dual task tests. Group-time interaction was different in the TUG-cognitive and Tinetti Falls Efficacy Scale scores. Also, the effect of time was significantly different in all scales except for the 10MWT-single task in both groups. Conclusion At the end of the 8-week training period, the impact of integrated and consecutive dual-task balance training on balance and gait performance in older adults was not statistically significantly different. This study suggests that consecutive dual-task balance training can be used as an alternative method to increase balance performance and gait speed in older adults who cannot perform integrated dual-task activities. Impact There were no significant differences between the effects of the 2 dual-task training methods on balance and gait speed, suggesting that the consecutive dual-task balance training method can be used to improve the balance and gait of older adults. CDTT can be performed safely and considered as an alternative method for use in many rehabilitation training programs with older adults who cannot perform simultaneous activities.Publication Open Access The relationship between sit-to-stand task and fat tissue & lean body mass(2020-10-01) AVCI, ENDER ERSİN; AKGÜN, İREM; DEMİRBÜKEN, İLKŞAN; TİMURTAŞ, EREN; POLAT, MİNE GÜLDEN; Timurtaş E., Demirbüken İ., Avcı E.

G.Purpose: Since the use of normalized isokinetic strength was recently proposed to analyze sportive performance, it was aimed to examine relative isokinetic muscle strength as well as absolute strength in jump performance. Secondly, the investigation of the relationship between extremity-based and inter-extremity strength asymmetry and selected jump tasks was aimed. Methods: Thirty female professional volleyball players (23.70 ± 5.27 years) who has at least four training sessions per week participated to study during the pre-season period Peak torque (PT) of knee flexors and extensors at the speed of 60º/s and 180º/s were evaluated using isokinetic dynamometer. Jump height (cm) and relative power (W/kg) of vertical countermovement jump (CMJ) and squat jump (SJ) were tested by optojump photoelectric system. Results: A positive moderate correlation between PT and relative PT(rPT) at both speeds with jump height was detected (r = 0.365–0.594). It was found that jump power had a positive moderate to good correlation with PT(r = 0.557–0.731) and low to moderate correlation with rPT (r = 0.314–0.601). No significant correlation was found between hamstring/quadriceps ratio and bilateral muscle asymmetry with jump parameters (p > 0.05). Conclusions: Due to the relatively low level of relationship between normalized strength and performance, we suggest carrying out further studies examining the effects of normalized parameters on performance. Considering the findings based on strength asymmetry, the coordinated action of the relevant muscles may come to the forefront during the performance, rather than muscle strength.Publication Open Access Okul çağı dönemindeki serebral palsi’li çocuklarda görsel-motor algı etkilenimi(2022-03-01) OĞUZ, SEMRA; DUMAN ÖZKAN, TUĞÇE; YILDIZ ÖZER, AYSEL; POLAT, MİNE GÜLDEN; Oğuz S., Duman Özkan T., Civelek M., Yıldız Özer A., Polat M. G.Serebral Palsi’li (SP) çocuklarda görsel bellek ve görsel algıdaki bozuklukların seviyesi beyindeki fonksiyonel bozuklukların seviyesine bağlıdır. Bu çocuklarda herhangi bir görme bozukluğu olsun ya da olmasın beyindeki fonksiyon bozuklukları görsel algılamada da bozulmaya neden olmaktadır. Çalışmamızın amacı, SP’li çocuklarda görsel-motor algı etkilenimini Bender Gestalt Görsel Motor Algılama Testi (BGGMAT) ile değerlendirmekti. Çalışmaya 5-11 yaş arası 30 sağlıklı, 30 SP’li çocuk dahil edildi. Değerlendirme BGGMAT ile yapıldı. İstatiksel analiz için IBM SPSS programı kullanıldı. Tanımlayıcı analizler nominal değişkenler için frekans tabloları; normal dağılmayan ve ordinal değişkenler için ortanca ve minimum- maksimum değerler kullanılarak verildi. Gruplar arası farklılığın belirlenmesinde nominal değişkenler için Ki-kare Testi, normal dağılmayan değişkenlerde MannWhitney U testi, grup içi değişkenler arası farklılığın belirlenmesinde ise Wilcoxon Testi kullanıldı. Yapılan değerlendirme sonucunda iki grup arasında persantil oranları bakımından anlamlı ölçüde fark saptanırken (p<0,05); hata puanı ve zekâ yaşları arasında istatiksel olarak anlamlı fark bulunmadı (p>0,05). SP’li bireylerde BGGMAT hata puanları, persantil oranları ve zekâ yaşları yaşa, cinsiyete ve alınan fizyoterapi süresine göre incelendiğinde, yaşa ve fizyoterapi süresine göre anlamlı fark olduğu gözlemlenirken (p<0,05); cinsiyetler arasında bir fark gözlenmedi (p>0,05). BGGMAT’e göre SP’li çocuklarda görsel-motor algının etkilendiği saptandı. Bu problemin rehabilitasyon sürecine olumsuz etkileri olabileceğinden SP’li çocuklarda rutin uygulamalara görselmotor algı değerlendirmesinin de eklenmesi gerektiğini düşünmekteyiz.Publication Open Access The effect of kinesiophobia on physical activity, balance, and fear of falling in patients with Parkinson's disease(2022-01-01) OĞUZ, SEMRA; POLAT, MİNE GÜLDEN; Oğuz S., Erturk G., Polat M. G., Apaydın H.Purpose Kinesiophobia is defined as the fear of movement and activity resulting from a feeling of vulnerability to painful injury or re-injury. This study aimed to determine the effect of kinesiophobia on physical activity, balance, and fear of falling in patients with Parkinson\"s disease. Methods The study, which was designed as a cross-sectional type, was conducted with 86 patients with Parkinson\"s disease (age 61.25 SD [9.72] years old) by face-to-face interviews with the patients. The Tampa Scale of Kinesiophobia, International Physical Activity Questionnaire-Short Form, Berg Balance Scale, Falls Efficacy Scale, Visual Analog Scale - Fear of Falling, Unified Parkinson\"s Disease Rating Scale - motor score, and the Hoehn and Yahr scale were used to evaluate the patients. Results Patients with Parkinson\"s disease who had high levels of kinesiophobia had lower levels of physical activity, worse balance, and higher disease severity and fear of falling. A correlation was found between the Tampa Scale score and physical activity, balance, fear of falling, falls efficacy, and disease motor score (p r = -0.38, -0.54, 0.67, 0.57, and 0.37, respectively). According to multiple linear regression analysis, kinesiophobia explained the dependent variables to varying degrees ranging from 13% to 44% (p < .001). Conclusions Patients with Parkinson\"s disease may have kinesiophobia. Rehabilitation programs to support functional capacity for these patients should be developed considering the presence of kinesiophobia.
