PendingUS20250322964A1Physical therapies and activitiesImage enhancementHip fractureFrailty assessment
An AI-assisted, data driven, real time posture detection system for physiotherapy, fall prevention, and / or frailty assessments. The system uses a pre-trained pose detection model and video images from multiple angles captured by multiple cameras to determine the three-dimensional locations of user joints in real time. In embodiments, the system calculates qualitative metrics (e.g., range of motion, ankle dorsiflexion, Q-angle, hip-knee-ankle alignment, gait speed, etc.) to determine whether the user has suffered or is at risk of an injury (e.g., ACL tear, patellar tendonitis, hip fracture, etc.) and / or whether a physiological condition has worsened or improved over time (e.g., after surgery or physical therapy). In some embodiments, the system constructs a digital twin of the user and displays a visual representation of the digital twin performing idealized movements (e.g., proper form for exercise or physical therapy) to provide real-time instruction and feedback to improve the physiological condition of the user.
