Future Day 2024

At this year's Future Day, the ARTORG Center opened its doors to inquisitive children aged 11 to 13 who wanted to gain an insight into the fascinating world of science and research.
The Musculoskeletal Biomechanics Lab welcomed five 7th-grade girls who had the opportunity to explore biomechanical research on bones. After an introductory overview of the subject, they delved into the structure of bones and participated in hands-on mechanical testing.
The rehabilitation center also welcomed a group of children to explore the use of modern technology and games within rehabilitation. After discovering and trying some playful therapeutic exercises, they had the opportunity to build their own rehabilitation game from electrical components.
