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 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 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.

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.
