The purpose of this study is to determine whether rhythmic upper-limb movement training in post-stroke patients allows to improve only this particular type of movements or if it also improves some parameters of discrete movements. Based on our results we hope to be able to answer a fundamental question: are rhythmic and discrete movements two independent primitives?
Patients are assessed four times during this longitudinal study. One month separates the first two assessment, next patients are trained 12 times during one month with rhythmic movement training on an end-effector robot. After this month, patients are assessed a third time and three months later a fourth time in order to study long-time benefits of the therapy.

Change in movement smoothness in rhythmic straight movements after one month of rhythmic therapy
Patients are asked to fulfill rhythmic movements on the end-effector robot Reaplan. The smoothness is assessed with following metrics: * number of peaks in velocity profile * TENT value * logarithmic dimensionless square jerk
Time frame: 1 week to 1 day before therapy and 1 day to 1 week after therapy
Change in movement smoothness in discrete straight movements after one month of rhythmic therapy
Patients are asked to fulfill discrete movements on the end-effector robot Reaplan. The smoothness is assessed with following metrics: * number of peaks in velocity profile * TENT value * logarithmic dimensionless square jerk
Time frame: 1 week to 1 day before therapy and 1 day to 1 week after therapy
Change in accuracy of discrete straight movements after one month of rhythmic therapy
Patients are asked to fulfill discrete movements on the end-effector robot Reaplan. The accuracy is assessed.
Time frame: 1 week to 1 day before therapy and 1 day to 1 week after therapy
Change in smoothness of rhythmic circular movement after rhythmic therapy
Patients are asked to fulfill 10 circular movements on the end-effector robot Reaplan. The movement smoothness are assessed
Time frame: 1 day to 1 week before therapy and 1day to 1 week after therapy
Change of the general motricity of the patient due to one month rhythmic therapy
1. Upper limb Fugl-Meyer Assessment 2. Box and block test 3. Ashworth test
Time frame: 1 week to 1 day before therapy and 1 day to 1 week after therapy

Evolution of the movement smoothness in rhythmic and discrete movements, the movement accuracy in discrete movements and the general motricity
Time frame: 1 day to one week after therapy and 3 months after therapy
Assessment of the natural evolution of the patient
Natural evolution of the movement smoothness in rhythmic and discrete movements, of the accuracy in discrete movements and of the general motricity of the patient
Time frame: 4 to 5 weeks before therapy and 1 week to 1 day before therapy
