Relationship of Proprioception, Reaction Time and the Gait and Balance Parameters After Stroke

The aim of this observational study is to analyze how impaired proprioception affects the gait, reaction time, balance and functioning of stroke patients. Research questions: * Are there correlations between the deficit of proprioception and reaction time and the parameters of gait and balance as well as the functional state of stroke patients? * Are there relationships between factors such as proprioception, reaction time, balance, functional status and gait, and time since stroke, the hemisphere where the stroke occurred, and gender? * Are there differences in proprioception deficits and reaction times between the lower limbs in stroke survivors? Participants will be assessed once using standard functional clinical tests and the rehabilitation devices. Researchers will compare stroke patients and healthy volunteers to see, if there are differences in proprioception deficits, reaction time and balance.
