The main purpose of this study will be to assess the consistency and reliability of measurements made using the Vicon three-plane gait analysis device (Vicon Motion Capture System Ltd, Oxford, UK) and a mobile application based on image recognition technology with the help of artificial intelligence.
The study will involve 50 healthy, physically active people aged 20-25. The participants will be subjected to movement analysis using the Vicon three-plane gait analysis system using reflective markers. Each of them will make 6 walks at their natural pace along a 10 m long path, during which a three-plane image of their walking will be recorded by the Vicon system. Additionally, during the examination, video recording of the full gait cycle in the sagittal plane from both sides, in the front plane from both sides and at an angle of 30, 45 and 60 degrees will be made using a smartphone camera. The recorded gait cycle using the camera will be analyzed in an image recognition application, which will generate angular values of the lower limb joints. First, the values generated by the Vicon system and the application from the sagittal plane recording will be compared. Then, the consistency of the values generated by the application from the recordings in the sagittal plane on both sides for the same lower limb will be checked. The last step will be to compare the compliance of the angular values from the Vicon system with the data generated in the application from recordings at angles of 60, 45, 30 and 0 degrees.

Gait analysis by the Vicon system
To perform gait analysis, it is necessary to attach reflective markers to the subject at specific anthropometric points. Participants will be asked to walk barefoot in a relaxed manner at a self-selected comfort speed through a 10-meter path (6 repetitions of walking). Each passage through the path will be recorded using the Vicon three-plane gait assessment system, which generates angular values of the ankle, knee and hip joints (degree).
Time frame: 45 minutes
Gait analysis by the mobile image recognition application
During the gait analysis using the Vicon system, video recording of the full gait cycle in the sagittal plane from both sides, in the front plane from both sides and at an angle of 30, 45 and 60 degrees will be made using a smartphone camera. The recorded gait cycle using the camera will be analyzed in an image recognition application, which will generate angular values of the lower limb joints (degree).
