Exploring interlimb constraints during bimanual graphic performance: effects of muscle grouping and direction

The integration of temporally shifted visual feedback in a synchronization task: The role of perceptual stability in a visuo-proprioceptive conflict situation

“…The performance in the in-phase synchronization mode corroborated the findings in the literature (Bingham et al, 1999;Bogaerts et al, 2003;Buekers et al, 2000;Langenberg et al, 1998;Roerdink, Peper, & Beek, 2005;Ryu & Buchanan, 2009;Swinnen, et al, 1998;Wilson, Collins, & Bingham, 2005a, 2005b. The spatial accuracy of the arm movements was significantly lower in the 50% feedback condition in which the spatial incompatibility (i.e., perception of the arm in a position that is incompatible with the proprioceptive information of the muscle afferents) between the target signal and the temporally shifted visual feedback of the actual arm movement was maximal Poulton, 1974).…”

“…Bimanual coordination studies have been very straightforward in showing that the in-phase coordination pattern (0° relative phase) is intrinsically more stable than the antiphase movement pattern (180° relative phase) (e.g., Swinnen, Jardin, Verschueren, Meulenbroek, Franz, Dounskaia et al, 1998;Zanone & Kelso, 1992). These phase effects were corroborated when the coordinated behavior is a product of the interaction between perception and action.…”

Transfer of learning between unimanual and bimanual rhythmic movement coordination: transfer is a function of the task dynamic

“…mirror symmetric movements in the fronto-parallel plane) are typically referred to as in-phase and are more stable than those which entail using non-homologous muscle groups at the same time (anti-phase). In the case of these two coordinations, that is, in phase or 0° and anti-phase or 180°, the egocentric constraint interacts with the allocentric constraint of whether the motion is in the same direction or not to affect overall coordination stability Swinnen et al 1998). However, a 90° coordination does not entail this interaction.…”

Combined effects of planning and execution constraints on bimanual task performance

“…These interference eVects were especially obvious when nonhomologous muscle pairs were activated (Li et al 2004). Ample studies showed an increased stability of arm movements in the symmetric mode (both hands/arms moving mirror-symmetrically with respect to the longitudinal axis of the body) compared to arm movements in the asymmetric mode (both hands/arms moving alternating with respect to the longitudinal axis of the body) (Byblow et al 1994;Semjen et al 1995;Swinnen et al 1997Swinnen et al , 1998Li et al 2004).…”
