INTRODUCTION: Cerebral palsy is a clinical entity which includes a group of non-progressive motor disorders which are often changing. They are caused by a disorder or damage to the brain before, during or after childbirth. It is the most common cause of severe neuromotor disorder in children, affecting 2-3/1000 of live-born children. Robotics in neurorehabilitation hepl in recovery on the principle of neuroplasticity. Lokomat is the world„s leading robotic medical device. It has been created with the purpose to regain the functionality of lower extremities of adult patients and children that have partially or fully lost it. At the same time, gait training is performed, proprioception is stimulated, and computer-based tasks for cognitive recovery are performed. AIM OF STUDY: Investigate the effect of the Lokomat on increasing the functionality and reducing tonus in children with spastic cerebral palsy. METHODS : The sample of respondents consists of thirty children with a classification of spastic cerebral palsy ranging from four to sixteen years. All of them had an individual rehabilitation theraphy program and under the supervision of a physiotherapist at the Lokomat rehabilitation device, 6 days a week for 40-50 minutes a day. They underwent testing at the beginning and at the end of the rehabilitation cycle. GMFM-88 test measurement at the beginning and end of rehabilitation program were performed to check the performance. The Lokomat measured the range, strength and tone of movement of the lower extremities (L-STIFF, L-FORCE). RESULTS: The research results showed that the effect of the Lokomat robotic device on the increase of functionality had a positive effect, while no statistically significant difference was shown on the reduction of tone and spasm in the lower extremities in children with spastic cerebral palsy. CONCLUSIONS: Thanks to robotic neurorehabilitation, which enables high doses and intensities of therapy, which strongly encourages neuroplasticity of the brain, through motor learning and repetition of tasks, it should become an equal method in neurorehabilitation as soon as possible.
