简要总结
In this study, it is aimed to examine the factors that cause knee hyperextension in chronic stroke patients. Although the presence of weakness or spasticity in the quadriceps muscle, weakness or spasticity in the plantar flexors, and weakness of the dorsiflexors, hamstrings and gastrocnemius muscle are shown in the literature as the cause of hyperextension of the affected knee in hemiplegic patients, there is a comprehensive study that shows the effect of both muscle strength and spasticity in the lower extremity muscles. there are no studies.
The hypotheses of the study are:
Hypothesis 1:
H0: There is no relationship between knee hyperextension in the stance phase of gait and lower extremity muscle strength in stroke patients.
H1: There is a relationship between knee hyperextension in the stance phase of gait and lower extremity muscle strength in stroke patients.
Hypothesis 2; H0: There is no relationship between knee hyperextension in the stance phase of gait and lower extremity spasticity in stroke patients.
H1: There is a relationship between knee hyperextension in the stance phase of gait and lower extremity spasticity in stroke patients.
Hypothesis 3; H0: There is no relationship between knee hyperextension and electromyographic muscle activations in chronic stroke patients.
H1: There is a relationship between knee hyperextension and electromyographic muscle activations in chronic stroke patients.

结局指标
主要结局
Movement Analysis
时间窗: Baseline
Reflective signs will be placed at certain anatomical points of the participants. Participants will be asked to walk a distance of 5 meters. The three-dimensional positions of these reflective marks will be recorded with the 8-camera Vicon motion capture system. Then it will be examined in computer environment using Blade software.
Electromyographic Measurements
时间窗: Baseline
Electromyography (EMG) is frequently used in the literature for motion analysis evaluations. It shows the amplitude of the electrical activity of the muscles. In this study, 8-channel Delsys Bagnoli desktop cable electromyography system (Delsys (Delsys Inc., USA)) will be used. EMG; It shows whether the muscles are active during movement, when they are active and how active they are. In this study, the muscles to be measured by EMG: tibialis anterior, medial gastrocnemius, medial hamstrings, rectus femoris, gluteus medius and the lower part of the latismus dorsi are planned.
