  • Deformities
  • Background and Purpose Although the relevance of understanding spinal kinematics during functional activities in patients with complex spinal deformities is undisputed among researchers and clinicians, evidence using skin marker-based motion capture systems is still limited to a handful of studies , mostly conducted on healthy subjects and using non-validated marker configurations.
