Core Functions of Plantar 3D Scanners in Dancer’s Foot Data Collection
I. Precise Data Acquisition
Structural Morphology Quantification
Non-contact laser scanning technology captures 3D parameters (e.g., arch height, toe alignment) with millimeter-level precision, providing objective evidence for identifying structural risks in ballet dancers (e.g., hallux valgus >15° or high arches).
Dynamic Adaptability Assessment
Combined with pressure plate testing, quantifies plantar pressure distribution changes in different foot positions (e.g., first and fifth positions), aiding in evaluating movement standards (e.g., detecting weight shift in parallel positions).
II. Extended Application Scenarios
Orthotic Solution Validation
3D models generated from scan data directly support custom orthotics design, with pressure tests verifying improvements (e.g., ≥20% reduction in midfoot pressure deemed effective).
Long-term Developmental Tracking
Regular scans establish arch development curves, particularly useful for early intervention in young dancers.
III. Collaborative Technical Advantages
Efficiency Enhancement
Single scans complete in seconds, avoiding training disruptions caused by traditional plaster molding.
Data Visualization
STL files integrate with 3D printing systems for rapid production of personalized shoe lasts or corrective devices.
