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 Metadata only Cross-cultural translation, validity, and reliability of the Turkish version of the Back Pain Attitudes Questionnaire(ELSEVIER, 2022) ÖZGÜL, BAHAR; Tay, Hilal Ata; Ozgul, Bahar; Darlow, Ben; Sari, ZubeyirBackground: As the Back Pain Attitudes Questionnaire (Back-PAQ), a validated instrument, could be performed to evaluate biopsychosocial dimensions of back pain, it has not been translated and adapted for Turkish population. Objectives: It was aimed to translate and cross-culturally adapt the Back-PAQ (versions of 34-item, 20-item, and 10-item) into Turkish language and analyse the validity and reliability of the Back-PAQ-Turkish version (Back-PAQ-Tr). Study design: Study of diagnostic accuracy/assessment scale. Methods: The translation and cross-cultural adaptation process were carried out in several steps according to international best-practice guidelines. 173 participants with back pain were recruited. Turkish version of the Tampa Scale of Kinesiophobia (TSK-Tr) and Fear Avoidance Beliefs Questionnaire (FABQ-Tr) were used to investigate the convergent validity. Results: Internal consistency of the Back-PAQ-Tr, Back-PAQ-Tr-20, and Back-PAQ-Tr-10 were 0.82, 0.78 and 0.68, respectively. Test-retest reliability was excellent for Back-PAQ-Tr (ICC = 0.95) and Back-PAQ-Tr-20 (ICC = 0.95), but weak for Back-PAQ-Tr-10 (ICC = 0.50). A weak correlation was found between all versions of Back-PAQ-Tr and TSK-Tr & FABQ-Tr, except for the moderate correlation between Back-PAQ-Tr-10 and TSK-Tr (r = -0.51) & the physical activity score of FABQ-Tr (r = -0.51). Back-PAQ-Tr, Back-PAQ-Tr-20, and Back-PAQ-Tr-10 accounted for 66.2%, 60.5%, and 78.2% of the variance in the data set, respectively. Conclusion: The versions of 34-item and 20-item Back-PAQ-Tr are reliable and valid questionnaire to assess Turkish populations' attitudes and beliefs regarding back pain. Since the reliability of the 10-item version was determined to be quite low, we particularly recommend the use of the versions of Back-PAQ-Tr and Back-PAQ-Tr-20.Publication Metadata only Rotator cuff disorders: A survey of current physiotherapy practice in Turkey(2023-01-01) ÖZGÜL, BAHAR; POLAT, MİNE GÜLDEN; AYBERK B., ÖZGÜL B., BURY J., POLAT M. G.Purpose: One of the most important factors guiding the physiotherapy program for rotator cuff disorders (RCD) is the clinical preferences of the physiotherapist in light of the evidence. However, the management parameters are remarkably variable between physiotherapists. It was aimed to describe the current physiotherapy practice of Turkish physiotherapists for the management of RCD and to explore its parallelism with the research evidence, and with the clinical perspective in European Countries. Methods: A cross-sectional online survey based on a clinical scenario that describes a typical patient with symptoms of RCD was conducted during July/August 2020. Descriptive responses of 104 physiotherapists were reported and analyzed by grouping physiotherapists with special interest (SI) who have further clinical experience or specialized training on RCD and no special interest (NSI). Results: The most preferred approaches were mobilization (82), scapular stabilization exercises (82), advice/education (71), and taping (62) considering all the participants. The preference rate of cold therapy (χ2=4.303, p=0.038) and isometric exercises (χ2=4.248, p=0.039) were significantly higher for physiotherapists with SI rather than NSI group. Conclusions: The most preferred management strategies of mobilization, exercise, and advice/education have been aligned with the preferences of physiotherapists from European countries and the current research evidence. However, passive modalities were also highly preferred. The management strategies differ between the physiotherapists who have SI and NSI. The high degree of practice variability and passive treatment preference of physiotherapists for the patients with RCD might be due to a lack of following the current literature evidence regularly.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 Metadata only The application of matrix rhythm therapy as a new clinical modality in burn physiotherapy programmes(ELSEVIER SCI LTD, 2014) ÖZGÜL, BAHAR; Sari, Zubeyir; Polat, Mine Gulden; Ozgul, Bahar; Aydogdu, Onur; Camcioglu, Burcu; Acar, Ahmet Hakan; Yurdalan, Saadet UfukPurpose: The aim of the present study was to investigate the use of matrix rhythm therapy (MRT) as one of the electrotherapeutic modalities in clinics. Methods: This study was carried out in the Burn and Wound Treatment Department of Dr. Lutfi Kirdar Kartal Education and Research Hospital in Istanbul between October 2010 and August 2011. A treatment protocol including whirlpool, MRT and exercise was applied to a group of patients who had burn injury of upper extremity. The evaluation of each patient included assessment of pain, range of motion, muscle strength, skin flexibility and sensory function at pre- and post-treatment. Results: There was no significant difference in values of pain, muscle strength and flexibility between pre- and post-treatment assessments (p > 0.05). A significant increase was found in the range of motion and sensory function at pre-treatment according to post-treatment (p < 0.01). Conclusion: The usage of MRT in order to maintain and improve the range of motion and to minimise the development of scar tissue was investigated in this study. We suggest conducting randomised controlled studies that carry out a comparison of the MRT with other treatment modalities with more cases and investigate the long-term effects of MRT.

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 Metadata only Kronik bel ağrısı olan bireylerde günlük yaşamda postüral alışkanlıkların incelenmesi(2022-12-16) ÖZGÜL, BAHAR; POLAT, MİNE GÜLDEN; ÖZGÜL B., TOPAL İ., POLAT M. G.Amaç: AraĢtırmanın birincil amacı kronik bel ağrısı Ģikâyeti yaĢayan bireylerin günlük yaĢamda vücut postürünü kullanım alıĢkanlıklarının araĢtırılmasıydı. AraĢtırmanın ikincil sorusu ise; bel ağrısı Ģiddetine göre postür kullanım alıĢkanlıklarının değiĢip değiĢmediği üzerineydi. Yöntem: Bel ağrısı Ģikâyeti bulunan 227 olgu (ortalama yaĢ 31,37±10,74 yıl), araĢtırmacılar tarafından hazırlanan çevrimiçi anketi tamamlamıĢtır. Anket içerisinde son bir aydır istirahat ve aktivite esnasındaki ağrı seviyesi vizuel analog skalası aracılığıyla ve günlük yaĢamda ayakta ve oturma süresi, sandalye ve koltukta oturma, yerden ağırlık kaldırma, ayakkabı giyme ve aĢağıya & yukarıya uzanma gibi aktivitelerde postür tercihleri görsel örnekler ile sorgulanmıĢtır. Bulgular: Günlük yaĢamda ayakta ve oturma süresi tüm olgular arasında %61 oranında 5 saat ve üzerindeydi. Sorgulanan tüm günlük yaĢam aktivitelerinde çoğunlukla (%65 ve üzeri) yanlıĢ postür tercih edilmekteydi. Postür kullanım alıĢkanlıklara göre ağrı Ģiddeti incelendiğinde; koltukta oturmada yanlıĢ postürü tercih edenlerin (t=- 1,674, p=,048), ve yukarı doğru uzanmada doğru postürü tercih edenlerin ağrı seviyesi daha yüksek (t=-1,844, p=,033) olarak saptandı. Sonuç: Bel ağrısı mevcut olan bireylerin günlük yaĢamda yüksek oranda yanlıĢ postürleri tercih ettiği görülmektedir. Ağrısı daha yoğun olan bireylerin yukarı uzanmada doğru postürü kullanmaları dikkat çekiciyken, daha yüksek seviyede ağrısı olan bireylerin koltukta yanlıĢ Ģekilde oturmayı tercih etmeye devam etmekteydi. AraĢtırmanın sonuçları incelendiğinde; kronik bel ağrısı olan bireylere günlük yaĢamda vücut postürünün ideal Ģekilde kullanımına dair eğitimler verilmesi gerektiğini ve bu eğitim programlarının etkinliğine yönelik ileri çalıĢmaların gerçekleĢtirilmesini önermekteyiz.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.
