Investigation of Knee Hyperextension and Femoral Cartilage Thickness in Chronic Stroke Patients

It is aimed to measure knee hyperextension and knee joint cartilage thickness in chronic stroke patients and to examine the relationship between the factors affecting knee hyperextension and knee joint cartilage thickness. This study, it is aimed to compare the knee joint cartilage thicknesses of the affected and unaffected extremities and to examine the relationship between knee hyperextension and knee joint cartilage thickness. The second aim is to compare the knee joint cartilage thickness of the paretic and nonparetic extremities and in stroke patients with and without knee hyperextension. The hypotheses of the study are: Hypothesis 1; H0: There is no difference between the knee joint cartilage thickness of the affected and unaffected extremities in chronic stroke patients with knee hyperextension. H1: In chronic stroke patients with knee hyperextension, there is a difference between the knee joint cartilage thicknesses of the affected and unaffected extremities. Hypothesis 2; H0: There is no relationship between knee hyperextension during the stance phase of gait and knee joint cartilage thickness in chronic stroke patients. H1: There is a relationship between knee hyperextension during the stance phase of gait and knee joint cartilage thickness in chronic stroke patients. Hypothesis 3; H0: There is no relationship between lower extremity muscle strength and spasticity and knee joint cartilage thickness in chronic stroke patients with knee hyperextension. H1: There is a relationship between lower extremity muscle strength and spasticity and knee joint cartilage thickness in chronic stroke patients with knee hyperextension. Hypothesis 4; H0: There is no difference between the cartilage thickness of the knee joint in chronic stroke patients with and without knee hyperextension. H1: There is a difference between the cartilage thickness of the knee joint in chronic stroke patients with and without knee hyperextension.
