Stroke is the third leading cause of death in the Republic of Croatia, while it is also the leading cause of disability in the world. Considering the comprehensiveness and complexity of the brain itself and the nervous system, the clinical picture is specific and very individual. According to etiology, stroke is divided into ischemic and hemorrhagic. Early and timely rehabilitation and treatment are key to reduced mortality and disability. Neurorehabilitation after a stroke represents a complex and exact approach and the collaboration of a multidisciplinary team, in order to encourage progress in all affected aspects while neuroplasticity is at a high level. A physiotherapist, as part of a multidisciplinary team, must be specially trained to work with neurological patients. With the development of technology in the last three decades, robotic systems are increasingly being used in neurorehabilitation. Today, there are various robotic devices for neurorehabilitation of the lower extremities that are used in rehabilitation after a stroke. One of the most sophisticated devices is Lokomat. Lokomat enables a large number of movement repetitions through intensive training with feedback, which makes it indicative in the rehabilitation of lower extremities and gait in patients after a stroke. The aim of this research was to examine the effect of Lokomat on increasing the strength of flexors and extensors of the hip and knee joints and on the speed and functionality of walking in chronic patients after a stroke. To assess success, the initial and final L-FORCE on the Lokomat device and the TUG test were performed in the experimental group, which were compared with the initial and final MMT and TUG test in the control group. The research refers to the younger population where the youngest respondent is 25 and the oldest is 50 years old. Initial and final strength and speed measurements on the Lokomat show generally greater improvements compared to the control group, but are not statistically significant compared to the control group, so further research is needed.
