Corrigendum to ‘‘Adjustments to McConville et al. and Young et al. body segment inertial parameters’’ [J. Biomech. 40 (2007) 543–553] R. Dumas, L. Che`ze, J.-P. Verriest Laboratoire de Biome´canique et Mode´lisation Humaine, Universite´ Claude Bernard Lyon 1–INRETS, Baˆtiment Omega, 43 Boulevard du 11 novembre 1918, 69 622 Villeurbanne cedex, France
The authors regret that an incorrect position for Head Vertex (HV) was used in the adjustment procedure of the data from McConville et al., 1980 and from Young et al., 1983 (Dumas et al., 2006). The correct position results in modified Head & Neck Segment Coordinate Systems (SCS) and modified segment length. The correct adjusted 3D positions of anatomical landmarks and centre of mass in Head & Neck SCS are: Segment
Anatomical Landmark
Head & Neck
Female
Head Vertex (HV) Sellion (SEL) Occiput (OCC) Centre Of Mass (COM)
