I need to translate a small part of the text into Greek:
In the experimental group were applied to the paretic leg 20 min of neurodevelopmental therapy and 20
min of muscle-strength-enhancement training. In the control group, 40 min of neurodevelopmental therapy
was applied. The method of concentric and eccentric muscle-strength-enhancement training for the paretic leg is as follows. A subject stands on a height-adjustable table where he/she is able to bear weight on the paretic leg while holding a stall bar with the upper limb on the paretic side. The subject pushes a ball back and forth on the ground using the non-paretic leg by controlling the ankle and knee joints of the paretic leg.
