Summary

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.
