Article Akredite Edilmiş ve Akredite Edilmemiş Fizyoterapi ve Rehabilitasyon Lisans Bölümlerindeki Öğrencilerin Akreditasyon Farkındalığının İncelenmesi(2026-02-27) Korkusuz, Süleyman; Korkusuz, Büşra Seçkinoğulları; Yuruk, Zeliha Ozlem; Taşkın, GülşenThis study aimed to examine the opinions about the general education process and accreditation awareness of students studying in accredited and non-accredited Physiotherapy and Rehabilitation (PTR) undergraduate departments. Ninety-one students studying in accredited departments and 104 students studying in non-accredited departments participated in the study. A survey form prepared by the researchers, adapted from literature, was used in the study. The survey included two sections: General education and functioning of the department (5 questions) and opinions on accreditation (12 questions). Students studying in accredited departments knew the accreditation concept better than students in non-accredited departments (p= .001). It was reported that students in accredited departments were more satisfied with the level of education and training provided by the department and the opportunities it offered to students (p<.05). It was also seen that students in non-accredited departments were more likely to think that accreditation provided advantages in terms of going abroad, education, and professional equality (p<.05). The students’ responses to the items about their overall satisfaction, participation in management and consulting process, accreditation requirement, impact of accreditation on education, physical conditions, facilitation, horizontal transition, and employment were similar between accredited and non-accredited departments (p>.05). The results show that students studying in PTR departments have high awareness of the benefits of accreditation, such as equal opportunities in education, improvement of education and training levels, and employment. Our results also emphasize that student representation should be considered in decision-making processes.Article Citation - WoS: 9Citation - Scopus: 9Balance and Gait in Individuals With Diabetic Peripheral Neuropathy(Taylor & Francis Ltd, 2023-09-15) Korkusuz, Suleyman; Seckinogullari, Busra; Yuruk, Zeliha Ozlem; Ulug, Naime; Kibar, SibelBackground: Diabetic Peripheral Neuropathy (DPN) causes various physical problems such as the increased risk of falling, loss of balance and coordination while standing or walking, susceptibility to injuries due to sensory loss.Aims: The aim of the study was to evaluate and compare the effects of neuropathic pain (NP) in individuals with DPN on balance and gait.Methods: This prospective controlled study was conducted on 42 adults aged between 40-65 years. The participants were divided into three groups; individuals with DPN and NP (DPN+NP/n = 14), individuals with DPN without NP (DPN-NP/n = 14), and the control group (n = 14), respectively. The Force Plate system and Core Balance System measured static and dynamic postural balance and stability limits. Gait and dynamic plantar pressure distribution analyses were performed with a computerized gait evaluation system.Results: The score of LANSS, and VAS during gait were higher in DPN+NP group than in DPN-NP (p < 0.05). No significant difference was observed between the groups in balance parameters (p > 0.05). The right-left heel maximum forces were lower in both groups with DPN compared to the control group (p < 0.05). In terms of spatiotemporal parameters of the gait, there was a difference between the groups only in step width and left single support line parameters (p < 0.05).Conclusions: The results of this study indicate that the individuals with DPN have an increased step width, their left single support line was shortened, and the maximum force on the heel decreased. The NP did not cause any change in balance and gait parameters.Article Citation - WoS: 2Citation - Scopus: 1Knee Hyperextension in Chronic Stroke: Associated Biomechanical and Neuromuscular Factors(Elsevier Sci Ltd, 2025-08) Korkusuz, Sueleyman; Korkusuz, Busra Seckinogullari; Ozgoren, Nihat; Aritan, Serdar; Ceren, Ali Naim; Topcuoglu, Mehmet Akif; Balkan, Ayla FilBackground: This study aimed to determine the gait phase in which knee hyperextension occurs in stroke patients and to investigate the factors associated with knee hyperextension. Methods: This study included 30 stroke patients aged between 40 and 70 years with maximum knee hyperextension during the stance phase of gait. Muscle strength was evaluated with manual muscle test, and muscle tone was assessed with the Modified Ashworth Scale. Kinematic evaluation of the patients was made using the motion analysis system. Additionally, categorisation was made according to the stance phase of gait, where knee hyperextension was at its highest. Findings: A weak relationship was found between maximum knee hyperextension angle and gastrocnemius spasticity, a moderate relationship between knee flexor muscle strength, and a moderate relationship between ankle dorsiflexor muscle strength. In addition, a weak relationship was found between the maximum knee hyperextension and pelvic retraction angles. According to this clustering, it was observed that 66.67 % of the participants (20 people) showed maximum knee hyperextension in the single support phase. It was observed that the participants who had maximum knee hyperextension, especially after the mid-stance phase, had higher mean gastrocnemius spasticity. It was also observed that participants in Cluster 4, with a greater amount of maximum knee hyperextension, had the worst clinical parameters. Interpretation: Our study observed that the degree of maximum knee hyperextension was related to knee flexor and ankle dorsiflexor muscle strengths, gastrocnemius spasticity and pelvic retraction. As clinical parameters worsened, maximum knee hyperextension was thought to occur late in the stance phase. Clinical Trial code: NCT05679700Article The Relationship of Cognitive Functions with Physical Fitness Parameters, Balance, and Fall Risk in Older Adults(2025-08-31) Yiğit, Öznur; Korkusuz, Süleyman; Korkusuz, Büşra SeçkinoğullarıObjectives: This study examines the effects of cognitive parameters on physical fitness, balance, and fall risk. Materials and Methods: The study included 79 older adults. Cognitive functions of older adults were assessed using the Montreal Cognitive Assessment Scale (MoCA) and Clock Drawing Test (CDT). The Berg Balance Scale (BBS) was used to assess balance and fall risk, and the Senior Fitness Test (SFT) was used to assess physical fitness parameters (PFP). According to MoCA, individuals were included in the Mild Cognitive Impairment (n=38) and Normal Cognitive Level (n=41) groups. Results: The mean age of individuals in the Mild Cognitive Impairment group was 71.50 ± 4.41, while the mean age of individuals in the Normal Cognitive Level group was 70.48 ± 4.57. In our study, individuals with mild cognitive impairment were found to have worse balance scores and physical fitness parameter scores, except for lower and upper extremity flexibility and aerobic endurance. While a significant relationship was noted between MoCA and balance as well as fall risk, no relationship was found between CDT and the balance score. Furthermore, no association between the CDT and any physical fitness parameter was found, despite a good correlation between the MoCA and several physical fitness parameters. Conclusion: In conclusion, it was shown that global cognition in geriatric individuals is related to balance and PFP, such as agility, upper and lower extremity strength.Article Citation - WoS: 10Citation - Scopus: 9Examining the Effects of Non-Immersive Virtual Reality Game-Based Training on Knee Hyperextension Control and Balance in Chronic Stroke Patients: a Single-Blind Randomized Controlled Study(Springer-verlag Italia Srl, 2024-10-28) Korkusuz, Suleyman; Taskin, Gulsen; Korkusuz, Buesra Seckinogullari; Ozen, Melike Sumeyye; Yuruk, Zeliha OzlemBackground Post-stroke hemiparesis can lead to decreased mobility, gait disturbances, impaired balance, postural instability, limitations in activities of daily living (ADL), and long-term disability. Aims The aim of this study was to examine the effect of non-immersive virtual reality game-based training (nIVRGT) in addition to conventional rehabilitation in stroke patients on dynamic balance, knee hyperextension control, and ADL. Methods Twenty-five chronic stroke patients aged between 51 and 70 were included in the study. Stroke patients were randomized to a control group (n = 12) and a study group (n = 13). Individuals in control group participated conventional physiotherapy and rehabilitation program for 60 min, 3 days a week for 6 weeks. individuals in the study group received 40 min of conventional physiotherapy and rehabilitation program plus 20 min nIVRGT. Functional Reach Test, Timed Up and Go Test, Computerized Gait Evaluation System and Barthel Index were used in the evaluation. Result The study group improved significantly in dynamic balance, knee control, and ADL (p < 0.05). In the control group, significant improvements were observed in dynamic balance and knee control (p < 0.05), except ADL (p > 0.05). The study group improved in dynamic balance compared with the control group (p < 0.05). Knee control and ADL improved similarly in both groups (p > 0.05). Conclusion Our results showed that conventional and additional nIVRGT rehabilitation improved dynamic balance and knee hyperextension control in chronic stroke. However, it was observed that the non-immersive virtual reality (nIVR) approach was more effective in improving dynamic balance in stroke patients than conventional rehabilitation alone.Article Sarcopenia Severity and Physical Fitness Levels in Nursing Home Residents and Community-Dwelling Older Adults(Springer London Ltd, 2026-05-29) Yavuz, Ferdi; Korkusuz, Süleyman; Korkusuz, Büşra Seçkinoğulları; Yürük, Zeliha ÖzlemBackground It is important to evaluate the physical fitness and sarcopenia levels of older adults, taking into account their living environment. Objective The aim of our study was to compare the sarcopenia severity and physical fitness levels of nursing home residents and community-dwelling older adults using the ISarcoPRM diagnostic algorithm incorporating ultrasonographic measures. Methods Nursing home residents (NHR) (n = 51) and community-dwelling older adults (CDO) (n = 52) were included in this cross-sectional study. Participants' physical fitness levels were assessed using the Senior Fitness Test (SFT). Sarcopenia severity was assessed using the 5r-Chair Stand Test (5r-CST) and hand grip strength (HGS), as well as the anterior thigh thickness (ATT) and Sonographic Thigh Adjustment Rate (STAR) obtained from ultrasonographic measurements. Participants were defined as nonsarcopenic, sarcopenic, and dynapenic according to the ISarcoPRM diagnostic algorithm of Kara et al. Result In our study, it was seen that individuals in NHR and CDO showed a homogeneous distribution in terms of sarcopenia severity (p > 0.05). When the groups were compared, the ATT, STAR, HGS and 5r-CST values of NHR were lower than CDO (p < 0.05). When comparing the groups, the physical fitness of NHR was lower than that of CDO according to SFT parameters (p < 0.05). Conclusion The results of our study showed that geriatric individuals living in NHR had higher levels of sarcopenia and lower levels of physical fitness than CDO. We believe that this result is due to the fact that NHR are dependent on caregivers in the institution where they live for their self-care and daily living activities.Article Citation - WoS: 2Citation - Scopus: 4Multi-Paradigm Metric and Its Applicability on Java Projects(Budapest Tech, 2013) Misra, Sanjay; Cafer, Ferid; Akman, Ibahim; Fernandez-Sanz, LuisJAVA is one of the favorite languages amongst software developers. However, the numbers of specific software metrics to evaluate the JAVA code are limited In this paper, we evaluate the applicability of a recently developed multi paradigm metric to JAVA projects. The experimentations show that the Multi paradigm metric is an effective measure for estimating the complexity of the JAVA code/projects, and therefore it can be used for controlling the quality of the projects. We have also evaluated the multi-paradigm metric against the principles of measurement theory.Article Citation - WoS: 3Citation - Scopus: 3Comparison of the Effectiveness of Kinesiology Taping and Rigid Taping on Ankle Kinematics During Drop Landing in Individuals With Lateral Ankle Injury(American Podiatric Medical Association, 2022-11) Korkusuz,S.; Kilic,R.T.; Aritan,S.; Ozgoren,N.; Sozay,S.; Kibar,S.; Yosmaoglu,H.B.Background: Lateral ankle sprain is an injury that often occurs during sports or daily life activ-ities. Athletic tape and kinesiology tape applications are among the external support treatment options especially for athletes to support the ankle and protect it from recurrent sprains. We sought to compare the kinematic stabilization effects of different ankle taping applications on the ankle joint during drop landing in individuals with a history of unilateral lateral ankle injury. Methods: In this randomized controlled study, 30 volunteers with unilateral ankle injury were evaluated. The participants were asked to land on one leg on the involved side and the contralateral side from a 30-cm-high platform. The same practice was repeated after apply-ing kinesiology tape and rigid tape to the injured foot. Kinematic analysis of the foot and ankle was performed by recording three-dimensional spatial position information at a speed of 240 frames per second using infrared cameras. Results: The highest inversion angles of the involved foot at initial contact and 150 msec after initial contact were higher than those of the uninvolved side (P = .03 and P = .04, respec-tively). There was no significant difference in ankle kinematic values in the involved foot among kinesiology taping, athletic taping, and no taping applications (P = .74). Conclusions: People with lateral ankle sprains show reduced inversion during landing. There were no significant differences among kinesiology taping, athletic taping, and no taping on the injured foot in terms of ankle kinematics. Care should be taken when using taping materials as protective measures for sports activities. © 2022, American Podiatric Medical Association.

The aim of our study was to evaluate the relationship between sarcopenia severity and trunk control, balance, respiratory function, and inspiratory muscle strength in patients with sarcopenic stroke. Forty-five patients voluntarily participated in our study. All patients were evaluated by a neurologist, diagnosed with stroke, and met the study's participation criteria. The level of the functional dependence of the patients was assessed by the Modified Rankin Scale (mRS). The severity of sarcopenia was calculated using the Sonographic Thigh Adjustment Ratio (STAR) formula, based on anterior thigh muscle mass measured by ultrasonography. In patients with chronic stroke, respiratory function was measured with a spirometer, and inspiratory muscle strength was measured with a Power Breath K5 device. Trunk control was assessed by the Trunk Impairment Scale (TIS), and balance was assessed by the Berg Balance Scale (BBS). In our study, a moderate positive correlation was observed between STAR value and balance, trunk control, inspiratory muscle strength, Forced Vital Capacity FVC (L), and Peak Expiratory Flow PEF (L/s), and a low positive correlation was observed between STAR value and FEV₁ (p<0.05). Furthermore, a moderate positive correlation was found between BBS and FVC (L) and FEV₁ (L), and a low positive correlation was found between BBS and PEF (L/s) and FEF 25–75 (%) (p<0.05). A low positive correlation was found between trunk control and volume (L), and a moderate positive correlation was found between TIS and FVC (L), FEV₁ (L), PEF (L/s), and FEF 25–75 (%) (p<0.05). In conclusion, our study demonstrated that the severity of sarcopenia in sarcopenic stroke patients is related to balance, trunk control, respiratory functions, and inspiratory muscle strength. Additionally, some pulmonary functions were found to be related to balance and trunk control. These findings demonstrated that considering the multidimensional functional components, including muscle mass, pulmonary function, balance, and trunk control, together is clinically important in planning rehabilitation programs.Article Citation - WoS: 1Citation - Scopus: 1Balance, Gait and Foot Pressure Distribution in Neuropathic Pain Associated with Lumbar Disc Degeneration(MDPI, 2025-02-21) Yavuz, Ferdi; Korkusuz, Suleyman; Korkusuz, Busra Seckinogullari; Yuruk, Zeliha Ozlem; Kibar, SibelBackground: This study aimed to evaluate the effects of NP associated with LDD on balance, gait and foot pressure distribution. Methods: This prospective controlled study was conducted on 42 individuals aged between 40 and 70 years. There were 3 groups in the study: individuals diagnosed with NP associated with LDD (n = 14), individuals with LDD without NP (n = 14), and the control group (n = 14). The Force Plate system and Core Balance System measured static and dynamic postural balance and stability limits. Gait and dynamic plantar pressure distribution analyses were performed with a computerized gait evaluation system. Results: The Leeds Assessment of Neuropathic Signs and Symptoms (LANSS), VAS during gait, and Oswestry Disability Index (ODI) scores were higher in the LDD with NP group than in the LDD without NP group (p < 0.05). It was found that LDD with NP group had backward dynamic balance control (p < 0.05). There was no significant difference in balance control, dynamic plantar pressure distribution, and spatiotemporal gait parameters between the groups (p > 0.05). Conclusions: Although participants with NP had higher levels of pain severity in gait and disability, there was no difference in postural balance, dynamic plantar pressure distribution, and spatiotemporal gait parameters compared to participants with LDD without NP and healthy individuals. All participants with LDD were unilaterally affected. Therefore, postural balance and gait tasks would be able to compensate for the unaffected limb.
