Pediatrics
• Scoliosis surgery
• Harms Study Group – Multi-Center – Develop database > 3000 patients – 8 year prospective study to evaluate
• A/P to P & staged vs not • Quality of life • Operative vs Non-operative outcomes • Risk of post operative infection • Evaluate natural history prior to surgical intervention
– Effect of diagnoses on treatment • Scheuermann’s Kyphosis • Cerebral Palsy Scoliosis • Marfan’s Syndrome • Congenital Scoliosis
Pediatrics Goals
• Create Spinal Deformity Center at UVA
• Develop new in house database – Prospective study to evaluate:
• Early onset scoliosis • Congenital scoliosis • Effects on lung function
– Employ EOS imaging (low dose 3D x-ray) – Dynamics MRI
Movement Analysis
• How do interventions effect human movement – Clinical
• Pre post surgery • Efficacy of interventions

Movement Analysis
• How do interventions effect human movement – Basic Science
• Why do we move the way we do • What is better? • Use models to answer questions
• Inertial Measurement Units, IMU
• Collect motion data out of lab
• Developed hyper precise calibration techniques
• Stride length within 2-3%
• Activity recognition Walking, running, stairs, incline
Take Research Out of Lab Setting
Where Next?
• How do interventions effect human movement
– Improve fidelity of models • Clinically
• Basic Science
– Develop better predictive routines
– Increase the ability to collect high quality motion data out of the lab environment
