(Taylor & Francis Ltd, 2024) Korkusuz, Suleyman; Seckinogullari, Busra; Yuruk, Zeliha Ozlem; Ulug, Naime; Kibar, Sibel
Background: 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.

(Amer Podiatric Med Assoc, 2022) Korkusuz, Suleyman; Kilic, Rabia Tugba; Aritan, Serdar; Ozgoren, Nihat; Sozay, Seyhan; Kibar, Sibel; Yosmaoglu, Hayri Baran
Background: Lateral ankle sprain is an injury that often occurs during sports or daily life activities. 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 applying 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, respectively). 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.

(Springer-Verlag Italia Srl, 2025) Korkusuz, Suleyman; Korkusuz, Busra Seckinogullari; Demircan, Emine Nur; Ozcan, Aysenur; Cakmakli, Gul Yalcin; Balkan, Ayla Fil; Elibol, Bulent
Background This study aimed to examine the gait parameters of individuals with Parkinson's Disease with and without freezing of gait (FoG) on the treadmill, where freezing difficulty decreases. Methods Our study included three groups of demographically similar individuals: 15 patients with Parkinson's disease without freezing of gait, 14 patients with Parkinson's disease with freezing of gait, and 14 healthy controls. Spatiotemporal parameters of gait and static-dynamic pedobarographic pressure distribution analysis were performed using a computerized gait evaluation system (on a treadmill). Results The step length, gait speed and gait phase duration of the freezing of gait group were lower than the other groups (p < 0.05). While pedobarographic pressure distribution during static stance was similar in all groups (p > 0.05), pedobarographic pressure distribution during gait was different between groups (p < 0.05). Conclusion In patients with freezing of gait, gait speed was lower, step length and single support phase were shorter, and double support phase was longer. While the amount of load on the backfoot was lower in both Parkinson's groups, the amount of load on the forefoot was lower only in patients with freezing of gait. Even if freezing of gait did not occur, it was observed that the gait characteristics of Parkinson's disease with freezing of gait were different from those of Parkinson's disease without freezing of gait.

(Lippincott Williams & Wilkins, 2024) Korkusuz, Suleyman; Kibar, Sibel; Ozgoren, Nihat; Aritan, Serdar; Seckinogullari, Busra; Balkan, Ayla Fil
ObjectiveKnee hyperextension is one of the most common compensatory mechanisms in stroke patients. The first aim of the study was to measure knee hyperextension and femoral cartilage thickness in stroke patients. The second aim was to compare the femoral cartilage thickness of the paretic and nonparetic limbs in stroke patients with and without knee hyperextension.DesignForty stroke patients were included in the study. The patients were divided into two groups according to the presence of knee hyperextension based on kinematic analyses performed during walking with a three-dimensional motion analysis system. The medial femoral cartilage, lateral femoral cartilage, and intercondylar cartilage thicknesses of the paretic and nonparetic sides of the patients were measured by ultrasonography.ResultsIn the study group, medial femoral cartilage, intercondylar, and lateral femoral cartilage thicknesses were less on the paretic side than on the nonparetic side, while the femoral cartilage thicknesses on the paretic and nonparetic sides were similar in the control group. Paretic side medial femoral cartilage and intercondylar thicknesses were less in the study group compared with the control group, and lateral femoral cartilage thickness was similar between the two groups.ConclusionsKnee hyperextension during walking causes femoral cartilage degeneration in stroke patients.Clinical Trial code: NCT05513157ConclusionsKnee hyperextension during walking causes femoral cartilage degeneration in stroke patients.Clinical Trial code: NCT05513157
Effects of Sensorimotor-Cognitive Training on Balance and Gait in Patients with Idiopathic Parkinson’s Disease: A Randomized Controlled Trial
(Springer London Ltd, 2026) Korkusuz, Suleyman; Elibol, Bulent; Ozcan, Aysenur; Korkusuz, Busra Seckinogullari; Fil, Ayla; Cakmakli, Gul Yalcin; Yigit, Oznur
Background Sensory-motor-cognitive integration deficits are common in Parkinson's disease(PD) and significantly limit functional performance, highlighting the growing need for holistic training approaches that target these domains simultaneously. Aims This study aimed to examine the effects of sensory-motor-cognitive integration training on balance and gait in patients with Parkinson's disease (PwPD). Methods A total of 40 PwPD, aged between 45 and 75 years, were included. The intervention group received 24 sessions (3 days per week for 8 weeks) of 60-minute sensory-motor-cognitive integration training. The control group was placed on a waiting list and continued their routine daily activities. All participants were assessed at baseline, at the end of the 8th week, and at the 12th week. Static posturography was used to evaluate balance [Limits of Stability and the Modified Sensory Integration and Balance Clinical Test] and gait (Walk Across test). Additionally, balance was assessed using the Functional Reach Test (FRT), and gait performance was evaluated with the Modified Dynamic Gait Index (mDGI). Results Significant time & times; group interactions were observed for functional balance and gait outcomes. The intervention group showed significant improvements in FRT and mDGI scores over time (p < 0.001), whereas no significant changes were observed in the control group. Static posturography also demonstrated significant time-related changes and group differences for most parameters (p < 0.05), except for movement velocity, directional control, and step length symmetry. Conclusion These findings suggest that individualized, multidomain sensory-motor-cognitive integration training may represent a particularly effective rehabilitation approach for enhancing balance and gait in PwPD.

Examining 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) Korkusuz, Suleyman; Taskin, Gulsen; Korkusuz, Buesra Seckinogullari; Ozen, Melike Sumeyye; Yuruk, Zeliha Ozlem
Background 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.

Investigation the Effect of Rigid Taping on Knee and Hip Joint Kinematics in Chronic Stroke Patients With Knee Hyperextension Gait
(Elsevier Ireland Ltd, 2025) Korkusuz, Suleyman; Fil-Balkan, Ayla; Korkusuz, Busra Seckinogullari; Ozgoren, Nihat; Aritan, Serdar; Ceren, Ali Naim; Topcuoglu, Mehmet Akif
Background: Although stroke patients gain an advantage in gait due to the knee hyperextension that occurs during the stance phase, this situation disrupts the biomechanical structure of the knee and increases the risk of injury to the capsular and ligamentous structures. The aim of this study was to examine the effects of rigid taping on hyperextension control and pelvic kinematics in stroke patients with knee hyperextension during the stance phase of gait. Research question: Does rigid taping have an effect on hyperextension control and pelvic kinematics in stroke patients with knee hyperextension? Methods: Thirty stroke patients aged between 40 and 70 were included in this pre-postintervention study. Kinematic assessment of gait was performed using a motion analysis system (Vicon Ltd, Bilston). Then, the rigid taping was applied to the patients using the hyperextension taping technique, and the kinematic analysis of the gait was repeated with the motion analysis system. Results: It was found that the rigid taping for the knee hyperextension significantly reduced the knee hyperextension (p < 0.05). Additionally, it was observed that the rigid taping significantly reduced the pelvic retraction (p < 0.05). However, no change was observed in the pelvic drop with the rigid taping application. Significance: Our results showed that the rigid taping effectively controlled the knee hyperextension. It was thought that the rigid taping application contributed to reducing knee hyperextension and pelvic retraction because it mechanically gave the knee a flexion moment and provided proprioceptive input.
