Quantification of three-dimensional (3-D) upper extremity (UE) joint motions and forces during Lofstrand crutch, walker, and wheelchair mobility is essential for improved long-term care of children with orthopaedic disabilities. Large joint ranges of motion combined with high joint loads during assistive mobility device usage have been shown to lead to pain and pathology. The investigation of UE joint demands may have significant impact on rehabilitation protocols and transitional care.
Advanced mobility modeling techniques using 3-D inverse dynamics methods are proposed to assess wheelchair mobility, Lofstrand crutch and walker-assisted gait in children with cerebral palsy, spinal cord injury, myelomeningocele, and osteogenesis imperfecta. Our UE model computes triaxial wrist, elbow and shoulder complex kinematics and kinetics utilizing our custom designed force sensing assistive devices. The model is demonstrated in a pediatric population of assistive device users with orthopaedic disabilities for biomechanical assessment. This work provides quantitative framework to support training paradigms, alternative mobility patterns and redesigned assistive devices to reduce the risk of pain and pathology.
