    (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.

    The immediate effect of patellar tendon strap on weight-bearing asymmetry during squatting in patients with unilateral knee osteoarthritis: A pilot study
    (SAGE PUBLICATIONS LTD, 2016) DEMİRBÜKEN, İLKŞAN; Demirbuken, Ilksan; Ozyurek, Seher; Angin, Salih
    Background: Knee osteoarthritis has commonly been associated with a symptom of pain resulting in an inter-limb weight-bearing asymmetry during functional tasks. Patellar tendon strap is one of the non-pharmacologic interventions to alleviate knee pain. Objectives: To investigate the immediate effect of a patellar tendon strap on weight-bearing asymmetry during squatting in people with unilateral knee osteoarthritis. Study design: Cross-sectional study. Methods: Ten patients with unilateral knee osteoarthritis and 10 healthy subjects were included in the study. Weight-bearing asymmetry of patients was assessed using a weight-bearing squat test during squatting at 30 degrees and 60 degrees both with and without patellar tendon strap. Pain intensity was assessed during squatting in unstrapped and strapped conditions with Visual Analog Scale. Results: The decrease in weight-bearing asymmetry values immediately after wearing patellar tendon strap during 30 degrees (p=0.006) and 60 degrees (p=0.011) of squatting tests was significantly higher in knee osteoarthritis patients than in healthy subjects. Reported pain intensity was similar in unstrapped and strapped conditions (p=0.066). Conclusion: The results of this study showed improved inter-limb weight-bearing symmetry during squatting. Further research with larger sample sizes investigating the effect of patellar tendon strap on weight-bearing asymmetry during functional activities in people with knee osteoarthritis is warranted. Clinical relevance Patellar tendon straps (easily fit and cheap unlike knee braces) had more improvements in inter-limb weight-bearing symmetry during squatting in people with knee osteoarthritis compared to healthy subjects. This study is a new insight for future studies to investigate clinical benefits of wearing patellar tendon straps in this population.

    (SPRINGER HEIDELBERG, 2017) ACAR, GÖNÜL; Colak, Tugba Kuru; Kavlak, Bahar; Aydogdu, Onur; Sahin, Emir; Acar, Gonul; Demirbuken, Ilksan; Sari, Zubeyir; Colak, Ilker; Bulut, Guven; Polat, M. Gulden
    The aim of the study was to compare the effects of low-intensity exercise programs for lower extremities, either supervised or at home, on pain, muscle strength, balance and the hemodynamic parameters of knee osteoarthritis (OA) patients. This randomized study included 78 patients with knee OA in 2 groups of supervised and home-based exercise program. Exercises were applied to the first group in the clinic as a group exercise program and were demonstrated to the second group to be performed at home. Before and after the 6-week exercise program, assessment was made of pain, quadriceps and hamstring muscle strengths, 6-min walk test (6MWT), and non-invasive hemodynamic parameters. Results of the 78 patients, 56 completed the study. Pain, muscle strength, and 6MWT scores showed significant improvements in both groups. There were also significant differences in the amount of change in pain and muscle strength (pain: p = 0.041, Rqdc: 0.009, Lqdc: 0.013, Rhms: 0.04) which indicated greater improvements in the supervised group. The balance scores of supervised group showed a significant improvement (p = 0.009). No significant change was determined in hemodynamic parameters of either group. Conclusion according to the results of this study showed that low-intensity lower extremity exercises conducted in a clinic under the supervision of a physiotherapist were more effective than home-based exercises in reducing post-activity pain levels and improving quadriceps and right hamstring muscle strength. Both the supervised and home exercise programs were seen to be effective in reducing rest pain and increasing 6 MW distance in knee osteoarthritis patients.

    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.

    Background Using mobile application for postural assessments has been drawing a rising interest due to widespread use of smartphones. 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.

    (AVES PRESS LTD, 2016) DEMİRBÜKEN, İLKŞAN; Ergin, Cagla; Yurdalan, Saadet Ufuk; Demirbuken, Ilksan; Zengin, Orhan
    Objective: This study aimed to investigate the fatigue and physical activity levels of smoking and non-smoking healthy sedentary individuals. Methods: The study was conducted with 191 sedentary university students who were informed regarding the study (age of smoking individuals, 21.01 +/- 1.34 years and age of non-smoking individuals, 20.76 +/- 1.65 years). The short form of the International Physical Activity Questionnaire was used to assess the physical activity levels, and the Piper Fatigue Scale was used to assess the fatigue levels. Results: There were no significant differences between the high, moderate, low intensity, and total physical activity levels of smoking and non-smoking healthy sedentary individuals (p>0.05). There was no statistical difference between the emotional fatigue levels of smoking and non-smoking healthy sedentary individuals (p>0.05), while statistically higher cognitive, sensory, behavioral, and total fatigue scores were observed in smoking healthy sedentary individuals than in non-smoking healthy sedentary individuals (p<0.05). Conclusion: Smoking affects cognitive, sensory, behavioral, and total fatigue levels in young sedentary individuals. It may be useful to inform university students regarding the effects of smoking on fatigue levels with respect to public health.
