The study aims to assess the function of knee joints in patients after stroke compared to healthy people and evaluate the impact of rehabilitation on the function of knee joints in people after stroke.
Stroke patients were examined twice at the beginning of rehabilitation and after approximately 15 days of exercise. The control group (healthy participants) was assessed once. Wireless motion sensors connected to a mobile application were used to assess the kinematics of the knee joints. They were used to assess the range of motion in the knee joints (passive, active, active at maximum speed), proprioception (joint position sense tests), step-up test, step-down test, getting up and sitting on a chair, step and squat. Functional tests such as The Five Times Sit-to-Stand Test, Timed Up\&Go, The Step Test, the 5m walking test, and the 30-s Chair Stand Test were carried out. The strength of the knee extensors and flexors was also assessed using the Leg Force Feedback device. Balance was assessed on a posturography platform by performing tests such as standing with eyes open and closed on a stable surface and standing with eyes open and closed on an unstable surface. The symmetry of lower limb loads in a standing position was also assessed.

The study group comprised patients after stroke. The control group consisted of healthy volunteers.
Inclusion criteria to the stroke group were as follows :
Exclusion criteria from the post-stroke group were as follows:
The control group consisted of healthy volunteers with no prior history of trauma or neurological disease affecting the structure and function of the lower limb.
All patients from the stroke group were examined twice at the beginning and the end of this trial by a physical therapist. Patients participated in a rehabilitation program at the Neurological Rehabilitation Department between measurements.
Other: Rehabilitation
The control group consisted of healthy subjects.
People after a stroke participated in a standard rehabilitation process carried out at the neurological rehabilitation department.

Assessment of the center of pressure path length when measuring on a balance platform
Measurement of parameter such as total path length (cm). A test was performed in four conditions: standing with eyes open and closed on a stable surface and standing with eyes open and closed on an unstable surface.
Time frame: Baseline and after about 15 days of exercise.
Assessment of the center of pressure velocity when measuring on a balance platform
Assessment of parameter such as average speed (cm/s). A test was performed in four conditions: standing with eyes open and closed on a stable surface and standing with eyes open and closed on an unstable surface.
