Article Citation - WoS: 3Citation - Scopus: 3Effect of Knee Hyperextension on Femoral Cartilage Thickness in Stroke Patients(Lippincott Williams & Wilkins, 2024) Korkusuz, Suleyman; Kibar, Sibel; Ozgoren, Nihat; Aritan, Serdar; Seckinogullari, Busra; Balkan, Ayla FilObjectiveKnee 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: NCT05513157Article Citation - WoS: 5Citation - Scopus: 4Examining 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 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.
