Title: | Head movements destabilize cyclical in-phase but not anti-phase homologous limb coordination in humans | Authors: | MEESEN, Raf Levin, O. Wenderoth, N. Swinnen, S.P. |
Issue Date: | 2003 | Publisher: | Source: | NEUROSCIENCE LETTERS, 340 (3) , p. 229 -233 | Abstract: | The present study addressed the role of head movements in the coordination of the homologous upper or lower limbs in supine normal subjects. Consistent with previous research, in-phase mirror symmetrical movements were performed more accurately and consistently than anti-phase movements. However, inclusion of head movements destabilized in-phase but not anti-phase homologous limb coordination, in contrast to previous work demonstrating a higher vulnerability of anti-phase than in-phase coordination to various experimental perturbations. It was observed that the head moved in the same direction as the limbs during anti- but not during in-phase coordination. Furthermore, the interlimb patterns also affected the head rotations that were lower in spatiotemporal consistency and less consistently coupled with the limbs during in-phase than during anti-phase coordination. These findings provide new insights into the coalition of egocentric and allocentric constraints during interlimb coordination. | Keywords: | Interlimb coordination;Egocentric;Allocentric;Homologous limbs;Motor control;Relative phase;Coordination constraints | Document URI: | http://hdl.handle.net/1942/30905 | ISSN: | 0304-3940 | e-ISSN: | 1872-7972 | DOI: | 10.1016/s0304-3940(02)01335-6 | Category: | A1 | Type: | Journal Contribution |
