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: 1Citation - Scopus: 1Investigation 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 AkifBackground: 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.
