“…In the mixed condition the low and high ID movements resulted in different velocities, but the velocity profiles (e.g., time of peak velocity) were almost perfectly synchronous (also see Kelso, Putnam, & Goodman, 1983). In Experiments 2 and 3 the targets were placed so that movements were toward the midline or away from the body, yet the results were remarkably similar to that from Experiment 1 (also see Heuer & Klein, 2006;Marteniuk et al, 1984;Spijkers, Tachmatzidis, Debus, Fischer, & Kausche, 1994). Taken together, these findings were interpreted by Kelso et al as indicating that the Blimbs are constrained to act as a single unit^with the more difficult task appearing to determine the time course of both limb movements.…”

“…According to the crosstalk model, two independent motor plans exist for each limb and some fraction of the force commands for one limb is diverted to the other limb (Cattaert et al, 1999). It has been proposed that the movements produced by the symmetric activation of homologous muscles are stabilized when the contralateral and ipsilateral signals are integrated, while movements produced by the activation of nonhomologous muscles or asymmetric activation suffer from ongoing interference due to conflicting information and partial intermingling of signals controlling the two arms (e.g., Kagerer et al, 2003;Kennedy, Boyle, Rhee, & Shea, 2015a;Marteniuk, MacKenzie, & Baba, 1984).…”

Perception and action influences on discrete and reciprocal bimanual coordination

For nearly four decades bimanual coordination, Ba prototype of complex motor skills^and apparent Bwindow into the design of the brain,^has been intensively studied. Past research has focused on describing and modeling the constraints that allow the production of some coordination patterns while limiting effective performance of other bimanual coordination patterns. More recently researchers have identified a coalition of perception-action constraints that hinder the effective production of bimanual skills. The result has been that given specially designed contexts where one or more of these constraints are minimized, bimanual skills once thought difficult, if not impossible, to effectively produce without very extensive practice can be executed effectively with little or no practice. The challenge is to understand how these contextual constraints interact to allow or inhibit the production of complex bimanual coordination skills. In addition, the factors affecting the stability of bimanual coordination tasks needs to be re-conceptualized in terms of perception-related constraints arising from the environmental context in which performance is conducted and action constraints resident in the neuromotor system.

“…In particular, such mechanisms may account for our observation that, in bimanual conditions, the rate of movement of the nonimpaired limb was reduced to that of the impaired limb. Explanations along similar lines have been put forward by Marteniuk et al (1984) and Swinnen et al (1991). When subjects are required to move a weighted and an unweighted stylus to a target, "assimilation" or synchronization effects are observed (Marteniuk et al 1985, experiment 2).…”

“…It has been shown subsequently that absolute synchrony is not obtained in circumstances in which the asymmetry in task demands (target size, movement amplitude or hurdle height) is in-creased (e.g. Goodman et al 1983;Marteniuk et al 1984;Fowler et al 1991).…”

Bimanual movement coordination in spastic hemiparesis

et al. 1996

A Fitts' task was used to examine whether the large movement asymmetry in subjects with spastic hemiparesis can be reduced or eliminated when both limbs are required to perform functionally equivalent tasks. Furthermore, it was determined whether any such benefit was expressed as mutual accommodation, or whether one hand "slaves" the other. Finally, the effect of increased task constraints on the magnitude of the asymmetry was considered. A group of ten students served as controls. Subjects had to grasp small balls and subsequently place them into holes. As expected, large total response time differences were present between the hands of the hemiparetic subjects in the unimanual conditions. However, 92% of the difference between hands was eliminated in the bimanual conditions. It is argued that the observed temporal invariance, or time locking, between hands in the bimanual conditions might be facilitated through the activity of bilateral controls exerted from each hemisphere and neural crosstalk at different levels of the central nervous system. Still, an asymmetric tendency remained in the bimanual conditions: a tendency existed for the impaired hand to reach the "target" later in time compared with the dominant hand. This tendency was enlarged as the asymmetry in task demands for the two limbs increased.

“…In drawing geometric shapes, as used in the present study, control processes manage the topological characteristics of the shape as well as the spatial characteristics of the components (number of segments and changes in direction), which together exemplify the complexity of the task. The latter is of additional importance when performing bimanual acts during which spatial coupling represents an intrinsic constraint [16,31]. This organization evokes bimanual interactions through a coupling mechanism of which the dominant limb exerts a stronger influence on the nondominant limb than vice versa [9,13].…”

Successful motor behavior depends on optimal information processing and planning. In the present study, the neural response of the motor system to conflict of visuomotor discrepancy (mirror-reversed vision) and complexity (task difficulty and hand laterality) was evaluated during the performance of bimanual actions. EEG coherence, expressing interregional communication, showed that conflict of visuomotor incongruence resulted in activation changes in both hemispheres, whereas conflict of task complexity evoked adjustments primarily in the left hemisphere. Furthermore, interhemispheric coherence was modified due to both forms of conflict. This demonstrates that conflict demands elicit distinct processes across the motor system. The data further illustrate that functional couplings are dynamically modulated during bimanual behaviour, suggesting that interactions between brain regions provide higher-order links for information processing and integration in view of complex motor skills.
