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
Take Research Out of Lab Setting
• 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
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
