Publication 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 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.

Elçin; Özgül, Bahar; Demirbüken, İlkşan; Alkaç, Çiğdem; Polat, M. GüldenPublication Open Access The association between isokinetic strength and strength asymmetry and jump performance in female volleyball players(2023-01-01) AYBERK, BAHAR; ÖZGÜL, BAHAR; POLAT, MİNE GÜLDEN; ATİK B., AYBERK B., ÖZGÜL B., POLAT M. 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 Gender and age impact on plantar pressure distribution in early adolescence(TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2019-05) ÖZGÜL, BAHAR; Demirbuken, Ilksan; Ozgul, Bahar; Timurtas, Eren; Yurdalan, Saadet Ufuk; Cekin, Murat Dincer; Polat, Mine GuldenObjective: The aim of the study was to investigate gender and age effect on dynamic plantar pressure distribution in early adolescence. Methods: A total of 524 adolescents (211 women and 313 men; mean age: 12.58 +/- 1.11 years (range: 11-14 years)) participated in pedobarographic measurements during gait at self-selected speed. Data of peak pressure (PP), maximum force (MaxF-Newton), body weight corrected maximum force (BW_MaxF), contact area (CA-cm(2)) were analyzed for total foot and four plantar regions (hindfoot, midfoot, forefoot and toes). Results: Higher toes PP was found in the ages of 12-14 years in females compared to males (253.79 +/- 104.93 vs 216.00 +/- 81.12 for the age of 12, p = 0.011, 264.40 +/- 65.02 vs 227.21 +/- 83.4 for the age of 13, p = 0.044, 299.75 +/- 140.60 vs 238.75 +/- 103.32 for the age of 14, p = 0.005). Females' higher MaxF especially for toes (136.24 +/- 48.54 vs 115.33 +/- 46.03, p = 0.008) and smaller CA especially for forefoot (50.12 +/- 5.79 vs 54.4893 +/- 6.80, p = 0.001) were considerable in the late of early adolescence. Forefoot (305.66 +/- 82.14 females p = 0.001, 281.35 +/- 79.59 males p < 0.001) and total foot PP (374.08 +/- 113.93 females, p = 0.035, 338.61 +/- 85.85 males p = 0.009) at the age of 14 was significantly higher than in younger ages in both gender groups. Conclusion: The results indicate that especially the age of 14 years in early adolescence is a critical age for alteration in plantar pressure distribution. Interestingly females tended to increase their toe and forefoot plantar pressures compared to males by increasing age. We suggest that gender and age impact on toes plantar pressure alterations in early adolescence may be a possible risk factor for further foot impairments.

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 Open Access Comparison of Two Different Proprioception Measurement Methods in the Shoulder Joint(2024-05-01) KILIÇ, TALHA; KURU ÇOLAK, TUĞBA; ÖZGÜL, BAHAR; Kılıç T., Kuru Çolak T., Tekin A., Özgül B., Çakmak Reyhan A.Aim: Proprioception assessment is important in shoulder rehabilitation. 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.
