FUT’nin, BDÖ ve GÖDÖarasındaki korelasyonları orta düzeyde bulundu (rho=0,453, rho=0,370, sırasıyla).Sonuç: Fonksiyonel uzanma testi, MS’si olan bireylerde güvenilir ve geçerlidir. Orta seviyede kriter ve içerik geçerliliğine sahipolup düşme riski hakkında bilgi verir. Ancak daha detaylı sonuçlar için SLT kullanılmalıdır.Öğe Commentary on Multidimensional Effects of Solid and Hinged Ankle-Foot Orthosis in Children With Cerebral Palsy(Lippincott Williams & Wilkins, 2021) Keklicek, Hilal; Demirel, Aynur[Abstract Not Available]Öğe Comparing the acute effect of myofascial release techniques and passive stretching on hind foot dynamic loading in patients with multiple sclerosis: A cohort-blinded study(Walter De Gruyter Gmbh, 2020) Balkan, Ayla Fil; Keklicek, Hilal; Salci, Yeliz; Altinkaynak, Umut; Armutlu, KadriyeStudy aim: It is important for therapists to incorporate new practical methods into therapy programs when they have demonstrable efficacy in the treatment of multiple sclerosis. Investigating the acute effects of myofascial release techniques (MFR) and passive stretching (PS) on hind foot loading and the severity of spasticity in individuals with multiple sclerosis (MS) was the aim of the study. Material and methods: Following the initial evaluation. 10 participants with MS (n = 20 feet) were given MFR for the plantar flexor muscle group. After the day following the first visit, participants were asked to come again and PS was applied to the plantar flexor muscle groups after the evaluation. The severity of spasticity was assessed with the Modified Ashworth Scale (MAS). Dynamic loading parameters of the hind foot - medial and lateral maximum pressure (N/cm(2)), active contact areas (cm(2)), contact percentiles (%) - were evaluated with dynamic pedobarography. Participants of the study were evaluated four times: (1) at the initial evaluation. (2) after MFR application, (3) 24 hours after the initial evaluation (pre-PS), (4) after PS. Results: There were no differences in MAS (p > 0.05) according to time-dependent analyses (p > 0.05). After MFR, the maximum pressure of the medial heel and active contact area were increased (p < 0.05) and there was a carryover effect on the maximum pressure of the right foot. Conclusions: This study showed that MFR was an effective method for management of plantar flexor spasticity in patients with multiple sclerosis in the short term and there was a carryover effect in favor of MFR. There was no additional effect of PS.Öğe Comparison of gait variability and symmetry in trained individuals with transtibial and transfemoral limb loss(Sage Publications Ltd, 2019) Keklicek, Hilal; Kirdi, Elif; Yalcin, Ali; Topuz, Semra; Ulger, Ozlem; Erbahceci, Fatih; Sener, GulPurpose: Gait variability is a determinant of qualified locomotion and is useful for monitoring the effects of therapeutic interventions. The aim of this study was to compare gait variability and symmetry in trained individuals with transtibial (TT) amputation and transfemoral (TF) amputation. Methods: The design of this study was planned as observational. Eleven individuals with TF amputation, 14 individuals with TT amputation, and 14 healthy individuals (HI) were evaluated with a motorized treadmill. The mean step length, the step length variability, an ambulation index, and the time on each foot (stance phase symmetry) of participants were recorded. Results: There were differences between the three groups in the residual/non-preferred limb (RNp) step length (p = 0.031), the intact/preferred (IP) limb step length variability (p = 0.001), the RNp step length variability (p < 0.001), the time on each foot (p < 0.001), and the ambulation index score (p < 0.001). There was a similarity between the groups (TF, TT, HI) in IP limb step lengths (p = 0.127) and duration of prosthesis usage since amputation in individuals with lower limb loss (p = 0.224). Conclusions: This study provided basic data about gait variability and symmetry in individuals with traumatic lower limb loss. The results of the study showed that the variability of gait increased with the level of loss, and individuals with TT amputation showed partially equivalent performance with the healthy group. Similarities in gait characteristics may have resulted from effective prosthetic usage or effective gait rehabilitation.Öğe Effects of arm swing on spatiotemporal characteristics of gait in unilateral transhumeral amputees(Elsevier Ireland Ltd, 2019) Topuz, Semra; Kirdi, Elif; Yalcin, Ali Imran; Ulger, Ozlem; Keklicek, Hilal; Sener, GulBackground: Gait is an autonomic process consisting of coordinated movements of the upper extremities, lower extremities, trunk and pelvis. However, researches regarding effects of upper extremity problems on gait parameters are limited. Research question: The aim of this study was to investigate the effects of arm swing on spatiotemporal characteristics of gait in individuals with unilateral transhumeral amputations. Methods: A total of 25 unilateral transhumeral amputees and 25 healthy subjects were included. Information on the demographic features of individuals, amputations, and prosthetic devices were recorded. Spatiotemporal characteristics of gait were obtained using the GAITRite electronic walkway, and the arm swing was evaluated with the two video-cameras and analyzed using the Dartfish Pro Suite 7 software. Results: The groups were similar regarding their age, height and weight. Mean duration from the amputation was 14.91 +/- 10.90 years, and the mean weight of the prostheses was 1.44 +/- 0.39 kg. Amputees had a less ambulatory arm swing on their amputated sides compared to their intact arms and healthy individuals. When the amputee group was compared to the healthy individuals, their step and stride lengths were shorter and their foot progression angle was higher, their gait velocity and cadence were lower than the healthy group. Significance: The reduction of arm swing on the amputated side in unilateral transhumeral amputees is thought to be due to (1) use of the contralateral side in functional activities, (2) restriction of shoulder joint movement of socket boundaries and (3) fixed mechanical elbow joint. It has been thought that a decrease in the arm swing during walking may lead to a decrease in step length, stride length, and gait velocity.Öğe The Effects of Instrumental Balance Training on Balance in Individuals with Unilateral Transtibial Amputation: A Pilot Study(Lippincott Williams & Wilkins, 2023) Kirdi, Elif; Yalcin, Ali; Keklicek, Hilal; Topuz, Semra; Ulger, Ozlem; Yazicioglu, GulIntroductionWith the loss of a lower limb, an individual with amputation may face impaired gait and balance. Different rehabilitation techniques can be used to deal with those functional disabilities. The purpose of this study was to determine whether computerized balance training could have any possible effects on balance in individuals with unilateral transtibial amputation.Materials and MethodsA total of 16 subjects who used a prosthesis in their daily life and were between 18 and 65 years of age were included in the study. Individuals were randomly divided into two groups: control group (CG) (n = 7) trained with traditional prosthetic rehabilitation and the experimental group (EG) (n = 9) trained with computerized balance training for five sessions for 2 weeks. Percentage of prosthetic weight bearing (PWB) timed up and go test (TUG), single-leg stance test (SLST), postural sway score, and limits of stability (LoS) were evaluated at baseline and posttreatment.ResultsNo significant differences were observed in between-group comparisons after treatment. Within-group comparison showed that PWB, SLST, and LoS score increased in EG, whereas only PWB increased in CG.ConclusionsSimilar results were revealed with both computerized and traditional prosthetic training. Although there were no significant differences in between-group comparisons, computerized balance training improved the amputated side single-leg stance and stability limits, which are highly related to fall risk in individuals with amputation.Öğe Effects of online education on prosthetics orthotics education during COVID-19(Wolters Kluwer Health, 2024) Uysal, Halil Hakan; Yildirim Sahan, Tezel; Keklicek, Hilal; Anaforoglu Kulunkoglu, BaharBackground:It is obvious that educational activities were affected globally due to the pandemic.Objective:This study was planned to examine the effects of online education on undergraduate degree (UD) and associate degree (AD) Orthotics and Prosthesis education in the COVID-19 pandemic.Study Design:A crossectional online survey.Method:The Google Forms questionnaire was delivered to students of Orthotics and Prosthesis in the level of undergraduate degree and AD and academicians conducted in the study. Next, the participants were reviewed regarding their knowledge about devices used for online education and related technical problems. A 5-point Likert-type questionnaire with 18 questions that was developed specifically for this study was applied to examine their views on online education.Results:The study included 472 participants who had a mean age of 21.30 +/- 0.22 years. Among the participants, 262 were AD students (55.5%). Approximately 82% of the participants were used their mobile phones for connection. The connection problems, and inappropriateness of online education in applied course, preference of online education for theoretical courses, insufficiency of digital course materials, failure to access education easily, insufficiency of online examinations for measurement and evaluation, and preference of homework over online education were stated by 79%, 88.3%, 41.9%, 54.5%, 70.1%, 41.7%, and 42.8% of the participants, respectively.Conclusion:Both academicians and students experienced connection problems, and applied courses were not suitable for online education. Motivation to attend the courses was low in online education, relevant workload increased, online examinations were not sufficient for measurement and evaluation, and studies were more unplanned. It is necessary to switch to formal education after the pandemic.Öğe Farklı Vücut Kitle İndeksi Düzeyinde Olan Bireylerde Statik Yük Altındaki Ayağın Pronasyon Cevabının İncelenmesi(2018) Keklicek, Hilal; Selçuk, HalitÇalışmanın amacı farklı vücut kitle indeksi (VKİ) düzeyinde olan bireylerde statik yük altındaki ayağın pronasyon cevabının araştırılmasıydı. Demografik veriler, VKİ değerleri (kg/m2) kaydedildi ve naviküler düşme miktarı (%) değerlendirildi. Değerlendirme tamamlandıktan sonra, katılımcılar üç gruba ayrıldı: düşük kilolu bireyler (VKİ <18,5 kg/m2), normal kilolu bireyler (VKİ=18,5-24,9 kg/m2), preobezite düzeyinde olan bireyler (25-29,9 kg/m2). İkili karşılaştırmalar, düşük kilolu grup ile normal kilolu grup (p = 0,012) arasında ve preobez grup ile normal kilolu grup arasında fark olduğunu gösterdi (p = 0,046). Düşük kilolu grup ile preobez grup arasında olmadığı görüldü (p=0,854). Çalışma, düşük kilolu ve preobez bireylerin ayağının pronasyon cevabının benzer olduğunu ve her iki grubun da normal kilolu bireylerden daha yüksek bir pronasyon cevabı oluşturduğunu gösterdi. Normal kiloda olmanın, statik yüklenme altında uygun ayak pronasyonu açısından önemli olduğu sonucuna varılmıştır.Öğe Fiziksel Aktivite Farkındalık Eğitiminin, Genç Bireylerin Aktivite Düzeyleri, Yürüyüş, Emosyonel Durum ve Yaşam Kalitesi Üzerine Etkisi(2019) Ülger, Güven Özlem; Balkan, Ayla Fil; Demirel, Aynur; Keklicek, Hilal; Ceren, Ali Naim; Onan, Dilara; Kara, DilaraAmaç: Genç bireylerde, fiziksel aktivitenin sağlık üzerine etkilerini anlatan farkındalık eğitiminin, fizikselaktivite(FA) düzeylerine olan etkilerini incelemekti.

Its neurologic complications include -but are not limited to headache, loss of smell, encephalitis, and cerebrovascular accidents. Even though gait analysis is an objective measure of the neuro-motor system and may provide significant information about the pathophysiology of specific diseases, no studies have investigated the gait characteristics in adults after full recovery from COVID-19. This was a cross-sectional, controlled study that included 12 individuals (mean age, 23.0 +/- 4.1 years) with mild-to-moderate COVID-19 history (COVD) and 20 sedentary controls (CONT; mean age, 24.0 +/- 3.6 years). Gait was evaluated using inertial sensors on a motorized treadmill. Spatial-temporal gait parameters and gait symmetry were calculated by using at least 512 consecutive steps for each participant. The effect-size analyses were utilized to interpret the impact of the results. Spatial-temporal gait characteristics were comparable between the two groups. The COVD group showed more asymmetrical gait patterns than the CONT group in the double support duration symmetry (p = 0.042), single support duration symmetry (p = 0.006), loading response duration symmetry (p = 0.042), and pre-swing duration symmetry (p = 0.018). The effect size analyses of the differences showed large effects (d = 0.68-0.831). Individuals with a history of mild-to-moderate COVID-19 showed more asymmetrical gait patterns than individuals without a disease history. Regardless of its severity, the multifaceted long-term effects of COVID-19 need to be examined and the scope of clinical follow-up should be detailed.Öğe Investigating the dynamic loading pattern of the foot in sedentary healthy adolescent(2020) Balkan, Ayla Fil; Keklicek, Hilal; Salcı, Yeliz; Akyol, BetülAim: The aims of this study were to define the dynamic loading pattern of the foot in healthy adolescents and to investigate thedifferences between boys and girls.Material and Methods: n = 89 adolescents (n = 42 girls, n = 47 males) using right hand-preferred and have normal body mass index(18.5- 24.9 kg/m2) were included in the study. Dynamic foot pressure analysis was used to determine the foot dynamical loadpatterns of the participants. The results were compared by considering be male or female factor and right-left foot dynamic loadingpattern.Results: In the comparison between the groups, it was seen that the contact percentages and active contact areas of the differentregions of the feet were different in boys and girls (p <0.05). When the right-left foot load patterns were compared, it was seen thatthe load transfer in the right foot progressed to the anterior medial and the left foot showed a delay in the load transfer processes(p <0.05).Conclusion: Boys walked with a wider contact percentage in the left foot and wider metatarsal and heel active contact areas in bothfeet than in girls. Furthermore, on the preferred side (right) the load transfer is positioned on the anterior medial of the foot, while themain difference in the other foot is due to the delay in reaching the maximum pressure.Öğe Investigating the dynamic plantar pressure distribution and loading pattern in subjects with multiple sclerosis(Elsevier Sci Ltd, 2018) Keklicek, Hilal; Cetin, Baris; Salci, Yeliz; Balkan, Ayla Fil; Altinkaynak, Umut; Armutlu, KadriyeBackground: Multiple sclerosis (MS) is a complex disorder affecting subjects by multiple system impairments. Gait problems are common in subjects with MS and various factors such as; ataxia, hypertonic muscles or/and seconder musculoskeletal system deformities affect the normal plantigrade contact by disturbing accommodation of foot to the ground while walking. The aim of this study was investigating the dynamic plantar pressure distribution and time of maximum pressure in subjects with MS and determining the differences from healthy subjects (HS). Methods: Fifty-five subjects with MS (110 foot) and 20 HS (40 foot) were the participants of the study. The dynamic pedobarograph was utilized for evaluation of dynamic loading parameters; maximum pressure (N/cm2) and time of maximum pressure (ms) collected from heel medial, heel lateral, midfoot, heads of first, second, third, fourth and fifth metatarsal bones. Results: There were differences between the groups in maximum pressure of heel medial (p < .001) and heel lateral (p < .001) was higher in HS. Also, there were differences between the groups the time of maximum pressure of all metatarsal head areas, midfoot, heel medial and heel lateral (p < .001). Subjects with MS spent lesser time to reach maximum pressure for forefoot loading and longer time for hindfoot loading. Conclusion: The study provided basic data about foot pressure distribution and time of maximum pressure in subjects with MS. Results of the study showed that the hindfoot loading was disrupted and inappropriate timing during load transfer from hindfoot to forefoot is exist in subjects with MS.Öğe Learning effect of dynamic postural stability evaluation system(Ios Press, 2019) Keklicek, Hilal; Kirdi, Elif; Yalcin, Ali; Yuce, Deniz; Topuz, SemraBACKGROUND: Repeated exposure to a given perturbation of the postural control system has been shown to cause learning of more efficient postural strategies for maintaining balance both within a session and over time. It is important to show whether outcomes from treatment strategies are related to the effectiveness of training or are the result of the learning of the test process. OBJECTIVE: To investigate the learning effect of the dynamic postural stability evaluation system. METHODS: We studied 20 healthy young subjects (13 females and 7 males), with a mean age of 22.3 +/- 1.9 years. Limits of stability and postural sway were assessed. All participants completed the standardized dynamic postural stability evaluation test (Bertec, Bertec Corporation, Columbus, OH, USA) seven times. The test was performed in both eyes open and eyes closed conditions. RESULTS: There were differences in the limits of stability scores for backward (p = 0.042), left side (p = 0.05), and the total score (p = 0.04). There were significant differences in postural sway anteroposterior direction in perturbed surface with eyes closed condition (p = 0.004) and total limits of stability scores of perturbed surface with eyes closed condition (p = 0.046). CONCLUSIONS: The study showed that balance test scores stabilized at different sessions from 1st to 3rd assessment period. Maximum normalized scores were reached at the third trial.Öğe Postural stability and flexibility responses of yoga training in women: Are improvements similar in both sexes?(Taylor & Francis Inc, 2023) Inal, Ozgu; Keklicek, Hilal; Karahan, Menekse; Ulucam, EnisThe researchers' aim is to examine the postural stability and flexibility responses of yoga training in women. The authors conducted the yoga training program 2 days a week and they assessed flexibility using the sit and reach test, trunk hyperextension test and trunk lateral flexion test. The researchers measured static and dynamic balance employing the device and database system. Then, the authors repeated all assesments were at the end of the first, the fifth and the tenth sessions. As a result of this study, the researchers revealed that the male participants had significantly poorer results in a single parameter (longitudinal sway) when compared with the female group, but the groups were statistically equivalent in this parameter after the first yoga training session. The authors also revealed that yoga was effective in improving flexibility among healthy young adults of both sexes, although the males showed greater improvement than females in the flexibility results.Öğe Primary dysmenorrhea and postural control: Is it a problem only during menstruation?(Elsevier Ireland Ltd, 2021) Keklicek, Hilal; Aydin, Nimet Sermenli; Can, Hilal Basak; Aydin, Didem Donmez; Kayatekin, Ayse Zeynep Yilmazer; Ulucam, EnisBackground: The effects of the menstrual cycle and primary dysmenorrhea (PD) on phase-related cognitive and physical functions are controversial. This study was carried out to examine whether women with PD showed a different physical function or dual-tasking response than women without PD at times other than menstruation. Methods: Women with or without PD were recruited for the study. Individuals assessed on the first day of the menstruation and the day they reported themselves as well being (feeling good day-FGD). Zebris ? FDM Type Force Platform was used to evaluate postural stability. Individuals have were asked to perform to a 3-step balance test protocol; the first session: comfortable upright standing; the second session: standing with a motor task; the third session: standing with a cognitive task (counting backward). Correctly calculated numbers were also recorded. Results: The number of correct answers given by individuals during the cognitive dual-task was similar on the first day of menstruation and FGD (p 0,05). In the assessments performed on the first day of menstruation, there was no difference in any parameters between the groups (p 0.05). In the measurements made on FGD day with the cognitive task; there was a difference between the groups (p < 0,05). Individuals with PD had higher postural sway. Significance: This study showed that the primary dysmenorrhea is not only a problem for females during menstruation, primary dysmenorrhea causes impaired ability of the individual to perform dual-tasking and continuously affects postural stability.Öğe The Relationship between Physical Activity Level and Physical Activity Awareness among University Students(2020) Aydın, Nimet Sermenli; Keklicek, HilalPurpose: The aim of this study was to determine physical activity awareness among university students, examine the relationship between physical activity and its awareness level and investigate whether there are differences according to gender. Material and Methods: Individuals (n=403) were assessed by an online form including a socio-demographic form, Cognitive Behavioral Physical Activity Questionnaire(CBPAQ), International Physical Activity Questionnaire-Short Form (IPAQ-SF). Daily step counts for 7 days were taken from participants whom agreed to report (n=162) by using their smartphone’s pedometer. Results: There was a significant correlation between physical activity level and the physical activity awareness (p<0.01). There was a significant positive correlation between the self-regulation (p<,001) and the outcome expectations (p=,006); a significant negative correlation between the personal barriers (p=,001). There was a positive correlation between the number of steps and the physical activity awareness (p=,02). The effect of the self-regulation on physical activity behavior in males had a greater effect than in females (p<001), and personal barriers for women had a greater impact on physical activity than in males (p=025). Discussion: It is thought that social and cognitive factors and gender-specific differences should be taken into consideration while determining the strategies and setting targets to promote physical activityÖğe Thoracal motion-based analysis of breathing patterns in individuals with a mild-moderate Covid-19 history using machine learning techniques: A single blinded multidisciplinary study on post-Covid(Elsevier Sci Ltd, 2024) Kurt, Lke; Selcuk, Halit; Ulukaya, Sezer; Ozturk, Guelnur; Keklicek, HilalBackground: Covid-19 led to deaths worldwide and left significant sequelae in a lot of people. Thoracic movements are important for the proper functioning of the respiratory system. However, there is no study on how the thoracic mobility of individuals who have recovered fully from Covid-19 is affected. Methods: In this study, the differences between thorax movements of healthy individuals and individuals with Covid-19 were investigated from a multidisciplinary perspective for the first time. Spontaneous and deep breathing data under two (at sitting- at standing) different conditions were collected and analyzed. In terms of engineering, using the Boruta feature selection method and various machine learning algorithms, discriminative features that will benefit clinically were determined. Clinically, the effect of Covid-19 was examined statistically in terms of respiratory biomechanics with thoracal motion-based analysis of 22 individuals. Results: The use of Boruta in sitting and standing positions during deep breathing increased the classification performance. In spontaneous breathing, using Boruta only in the sitting position provided an increase in classification performance achieving an accuracy of 95.45 %. The results of the study showed that respiratory movements of the thoracic cage in the anteroposterior and craniocaudal directions were more restricted and had weaker respiratory acceleration skills in individuals with a Covid-19 history (p < 0.05). Conclusion: From a clinical point of view, it was observed that the respiratory acceleration movements were restricted in individuals with a Covid-19 history even though full recovery. Also, it was revealed that machine learning models can classify with high performance in situations requiring effort.Öğe The trunk control: Which scale is the best in very acute stroke patients?(Taylor & Francis Ltd, 2019) Balkan, Ayla Fil; Salci, Yeliz; Keklicek, Hilal; Cetin, Baris; Adin, Ridvan Muhammed; Armutlu, KadriyeBackground: It is important to evaluate trunk control, given that it is one of the indicators of adequate functional and motor recovery in patients following a stroke. The assessment should be feasible and adequate in clinical conditions in the acute phase.Objectives: The aim of this study was to detect the most appropriate scale used for trunk control assessment in very acute stroke patients in terms of time and ease of implementation.Methods: Sixty-five patients with very acute stroke were included in the study. The patients were assessed with the Trunk Impairment Scale-1 (VTIS), the Trunk Impairment Scale-2 (FTIS), the Motor Assessment Scale trunk subscale (T-MAS) and the Trunk Control Test (TCT), and Functional Impairment Measure (FIM). Floor/ceiling effects, reliability, validity responsiveness of all trunk control scales analyzed. The correlation between all scales and FIM were calculated.Results: All scales had similar reliability, responsiveness and construct validity level. T-MAS and TCT were more advantageous than other scales according to time. TCT and VTIS showed floor effect. The best predictive validity values were observed for the T-MAS and TCT.Conclusions: Four scales investigated in this study can also be used to evaluate the patients with very acute stroke. On the other hand, the advantages and disadvantages of the scales should be thoroughly assessed and researchers can use one of four scales considering their aim, patient populations and clinical characteristics of patients
