Markerless Motion Capture in Foot and Ankle Surgery

Proof of Concept: ROM measured by the markerless system compared to clinical examination using a goniometer and motion capture analysis. The ROM of the ankle joint in the sagittal plane and the ROM of the subtalar joint in coronal plane of 20 healthy subjects will be analysed using three different methods: Clinical examination using a goniometer, Markerbased motion capture system, Markerless movement analysis. ROM measurements will be performed on both feet of 20 participants (40 feet total). Each measurement method will be performed 10 times per foot. Goniometer measurements will be performed by two independent investigators (10 measurements each), while marker-based and marker-less measure

Inclusion Criteria: * Healthy subjects between 18 - 65 years of age able to sign the informed consent form. Exclusion Criteria: * Injury, diseases or former surgery affecting the lower limb. Stiff joint, e.g. blocked subtalar joint motion defined as a ROM under 20°.
