1. Compare functionality of ASD and control subjects 2. Relate functionality of ASD patients to their pathology, in terms of spinal deformity and muscle condition
Adult (>18 years old) subjects suffering from a adult spinal deformity with sagittal or coronal plane misalignment diagnosed on EOS imaging.
