Article Effect of Freezing Phenomenon on Gait Parameters and Pedobarographic Pressure Distribution in Patients with Parkinson's Disease(Springer-Verlag Italia Srl, 2025) Korkusuz, Suleyman; Korkusuz, Busra Seckinogullari; Demircan, Emine Nur; Ozcan, Aysenur; Cakmakli, Gul Yalcin; Balkan, Ayla Fil; Elibol, BulentBackground 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.Article 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.
