In this study, the neck and head relative to the ground were more flexed, while the head relative to the neck was more extended, in the subjects who were blind than in the sighted subjects. The introduction of external (sound) or proprioceptive (mandibular position, look ahead) inputs modified craniocervical posture and relationships (extension) in both groups.
