Publication Open Access Reliability of balance evaluation using Pedalo®-Sensomove Balance device in healthy young individuals(2022-11-25) GÜNAY YAZICI, CANAN; ÖZEN BERKOL, TUĞÇE; ÖZGÜL, BAHAR; KURU ÇOLAK, TUĞBA; SARI, ZÜBEYİR; Günay Yazıcı C., Özen Berkol T., Özgül B., Kuru Çolak T., Sarı Z.Purpose: It is important to assess the integrity of the balance system to predict individual balance and coordination abilities. MarBES is a device consisting of 9 led scales and 4 pressure sensor systems developed to evaluate and improve balance and coordination as a TÜBİTAK 3001 project. Weight data is estimated from pressure sensors located in 4 different corners and a score is calculated with computer software for the individual\"s center of gravity (Centre of pressure X, Y) and the amount of deviation from the center for each axis.. The aim of this study is to examine the test-retest reliability of the MarBES device. Methods: Double-leg and single-leg (eyes open-closed) tests were applied to healthy young adult participants for balance testing on the MarBES device. Weight transfer to the target surface was measured for assessment of the participants coordination performance. Participants rested for 10 minutes and all measurements were repeated by the same evaluator. The obtained data were recorded and the reliability of the measurements was evaluated with Pearson correlation analysis. Results: A total of 33 healthy young individuals (24 F; 9 M) with a mean age of 21±0.96 years were included in the study. In the correlation analysis, there was a strong correlation in all measurement parameters of the MarBES device except for X axis measurements of right leg (eyes open) and double leg eyes closed (p<0.005). Conclusion: Objective evaluation of balance and coordination parameters is very important in rehabilitation. Resulde of the study showed that the MarBES device developed by the researchers is a reliable method for the evaluation of balance and coordination in healthy young individuals.

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 The relationship between diabetes knowledge level, physical activity, and quality of life in older adults(2023-08-01) KURU ÇOLAK, TUĞBA; ÖZGÜL, BAHAR; Akçay B., Kuru Çolak T., İğrek S., Özgül B., Apti A.Aim: This study aimed to examine the relationship between knowledge about diabetes, physical activity, and quality of life in older adults with type 2 diabetes. Material and Method: A total of 188 geriatric individuals with a mean age of 75.2 years were included in this study. The level of knowledge about diabetes was assessed by the Diabetes Information Questionnaire-24, the Kasari index was used to assess the level of physical activity, and quality of life was assessed by the Diabetes-39 Quality of Life Questionnaire. Results: The participants’ knowledge about diabetes, their physical activity levels according to the Kasari index, and Diabetes-39 quality of life scores were all low. It was determined that level of knowledge was significantly related to physical activity and the Diabetes-39 diabetes control subgroup score (p<0.005). There was a significant relationship between the Kasari index and Diabetes-39 quality of life total score (p<0.005). Conclusion: Level of knowledge about diabetes is related to physical activity and quality of life in elderly adults. It is important to encourage participation in training programs and increase physical activity to improve the quality of life of these individuals, who must live with this chronic disease for many years while also accompanied by geriatric symptoms.Publication Metadata only Ayak postürüne göre ayak bileği çevresi kas yapısının incelenmesi(2022-12-09) ÖZGÜL, BAHAR; DEMİRBÜKEN, İLKŞAN; POLAT, MİNE GÜLDEN; Özgül B., Aygün N. B., Demirbüken İ., Polat M. G.Amaç: Internal ve eksternal yumuşak doku yapıları, kuvvet ve dinamik destek uygulayarak ayak postürü üzerinde etkilere sahiptir. Bu çalışma kapsamında farklı ayak postürüne sahip bireylerde muskuloskeletal ultrasonik değerlendirmesiyle ile seçilen kasların yapısal karakterizasyonun gerçekleştirilmesi ve ayak bileği çevresinde yer alan majör kas gruplarının yapısal özelliklerinin karşılaştırılması amaçlandı. Yöntem: Otuz üç kadın olgunun (ortalama yaş: 21,45±1,60 yıl) dominant ayağı Ayak Postür İndeksi (APİ) uygulanarak değerlendirildi ve pron ayak postürüne sahip 15 olgu (APİ skoru = 6-10) ve normal ayak postürüne sahip 18 olgu (APİ skoru = 0-5) tespit edildi. Olguların tibialis anterior, gastrocnemius medialis ve peroneal kasların kalınlığı ve ek olarak peroneal kasların kesit alanı görüntüleri 5-13 MHz’lik bir prob ve Venue 40 ultrasonografik görüntüleme sistemi aracılığıyla toplandı. ImageJ programı kullanılarak üç farklı görüntünün ilgili yapısal özellikler analiz edildi ve ortalaması alındı. Ultrasonografik görüntüleme, uluslararası sertifikası olan ve beş yıldır muskuloskeletal ultrasonik görüntülemede tecrübesi olan fizyoterapist tarafından gerçekleştirildi. Bulgular: Her iki grupta yer alan olgular demografik özellikler açısından benzerdi (p>0,05). Pron ayak postürüne sahip bireylerin tibialis anterior (p=0,025, z=2,242), peroneus brevis (p=0,013, z=-2,459) ve total peroneus kas kalınlığının (p=0,007, z=2,639) normal ayak postürü grubundan daha fazla olduğu tespit edildi. Gastrocnemius medialis, peroneus longus kalınlığı ve peroneal kasların kesit alanı açısından gruplar arasında fark yoktu (p>0,05). Sonuç: Mevcut çalışmanın bulgularına göre, ayak postürüne göre ayak bileği hareketlerini kontrol eden tibialis anterior ve peroneal kasların kalınlığı farklılık gözlenmektedir. Daha fazla olgunun yer aldığı, ayak postürüne göre tendona aktarılan kuvvet hakkında daha detaylı bilgi verebilen penasyon açısının da değerlendirildiği ileri çalışmaların yapılması planlanmıştır.

Proprioception sense can be evaluated with different methods in the clinical setting. The aim of this study was to compare shoulder proprioception measurements made with universal goniometer and isokinetic system. Methods: A total of 52 healthy individuals with a mean age of 24.6 ±4.29 years were included in the study. Shoulder proprioception was evaluated three times with a universal goniometer and isokinetic device at 30, 45 and 60 degrees shoulder flexion angles with eyes closed in a sitting position and mean values were recorded. Results: When the results obtained with the two measurement methods were compared, it was determined that there was a significant difference between the mean values (for 30, 45 and 60 degrees shoulder flexion angles, p=0.003, 0.005, 0.000, respectively) and there was no correlation relationship between the results of the two measurement methods (p<0.05). However, when the mean deviation from the target angle was compared with both measurement methods, it was determined that there was no significant difference between the measurement methods (p<0.05). Conclusion: The findings of this study demonstrated that when shoulder proprioception was measured using a goniometer or an isokinetic dynamometer at various angles, different values could be obtained. However, since the differences compared to the target angle are similar for the two measurement methods, both assessment methods can be used for proprioception evaluation.
