Neuro-Behavioral Determinants of Interlimb Coordination by Stephan P. Swinnen download in iPad, ePub, pdf

Here, we continue with an overview of the current state-of-the-art in assessing or quantifying this type of coordination. In more recent years, Ivry et al. Such organization is reflected in spatiotemporal constraints upon execution of simultaneous movements. Under this framework, interlimb coordination is not only influenced by spatiotemporal constraints, but also by how tasks are cued and represented in higher centers in the brain. This was examined by comparing the coordination during unimanual and bimanual reaching movements.

These simulated or contrived

These simulated or contrived tasks may not be directly related to real-life situations, but they are simpler to apply. Dynamic pattern generation in behavioral and neural systems. In contrast to this view, the information-processing perspective, introduced by Marteniuk et al. Towards this end, we present a summary of different ways in which interlimb coordination has been studied and quantified. Nevertheless, it is worth to point out that, since there are no standard assessments that objectively and quantitatively assess individual components of body function e.

Dynamic pattern generation in

Finally, rehabilitation robots are programmed by engineers to automatically compute another set of metrics that attempt to quantify coordination between the upper limbs that interact with the robot. They are important because phase transitions provide a physical mechanism for the cooperative action of neurons. Neither argument holds water. The dominant arm is typically more efficient in controlling intersegmental dynamics and the nondominant arm has an advantage for maintaining limb posture. Transitions between dynamical states of differing stability in the human brain.

For treatment, neuroscience studies have motivated the use of bimanual therapies e. Such critical fluctuations were observed in Kelso's original experiments and later confirmed Kelso et al. In the clinic, protocols and outcome measures are tightly coupled, but coordination between upper limbs is rarely assessed directly. The meaning of the outcomes are based on validation studies of the assessment tests, which are done for each patient population the clinical test is meant to be used in.
