To develop and validate a dynamic motion analysis technique combining electrogoniometry and videofluoroscopy to assess lumbar spine kinematics in vivo.
Assessed dynamic lumbar flexion-extension in 30 healthy volunteers using a synchronized electrogoniometer and videofluoroscopy unit.
Captured continuous lumbar fluoroscopic images at 10-degree intervals across the total flexion-extension range of motion.
Calculated segmental intervertebral motion across each lumbar level (L1 through L5) to evaluate system reliability and movement patterns.
Lumbar vertebrae flexed sequentially in a descending order from L1 down to L5 throughout forward flexion.
The concavity of lumbar lordosis increased steadily throughout spinal extension.
Motion patterns showed no statistically significant differences between male and female participants.
