28 Bilateral movement rehabilitation is gaining popularity as an approach not only to improve the recovery 29 of bimanual function, but also of unilateral motor tasks. While the neural mechanisms mediating the 30 transfer of bilateral training gains into unimanual contexts are not fully understood, converging evidence 31 from behavioural, neurophysiological and imaging studies suggests that bim...

The purpose of this article was to describe a child-friendly modified constraint-induced movement therapy protocol that is combined with goal-directed task-specific bimanual training (mCIMT-BiT). This detailed description elucidates the approach and supports various research reports. This protocol is used in a Pirate play group setting and aims to extend bimanual skills in play and self-care ac...

When a neural movement controller, called an "internal model," is adapted to a novel environment, the movement error needs to be appropriately associated with the controller. However, their association is not necessarily guaranteed for bimanual movements in which two controllers--one for each hand--result in two movement errors. Considering the implicit nature of the adaptation process, the mov...

Previously, transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) has resulted in improved performance in simple motor tasks. For a complex bimanual movement, studies using functional magnetic resonance imaging and transcranial magnetic stimulation indicated the involvement of the left dorsolateral prefrontal cortex (DLPFC) as well as left M1. Here we investigated th...

OBJECTIVE To determine how stroke lesion side and ipsilateral motor pathways influence motor performance in bimanual tasks. METHODS Stroke subjects and age-matched controls participated in two data collection sessions: (1) motor behavior was examined during a movement task performed in unimanual, bimanual symmetric, and bimanual asymmetric conditions and (2) transcranial magnetic stimulation ...

AIM To investigate the neuronal activation pattern underlying the effects of mirror illusion in children/adolescents with normal motor development and in children/adolescents with hemiparesis and preserved contralateral corticospinal organisation. METHOD The type of cortical reorganisation was classified according to results of transcranial magnetic stimulation. Only subjects with congenital ...

Bimanual movements involve the interactions between both primary motor cortices. These interactions are assumed to involve phase-locked oscillatory brain activity referred to as inter-hemispheric functional coupling. So far, inter-hemispheric functional coupling has been investigated as a function of motor performance. These studies report mostly a negative correlation between the performance i...

Deficits in bimanual coordination of older adults have been demonstrated to significantly limit their functioning in daily life. As a bimanual sensorimotor task, instrument playing has great potential for motor and cognitive training in advanced age. While the process of matching a person's repetitive movements to auditory rhythmic cueing during instrument playing was documented to involve moto...

Background and Purpose Deficits in upper-extremity function in individuals with tetraplegia are primarily due to the loss of motor pathways. Detrimental cortical reorganization, however, may create further loss of function. The purpose of this case report is to describe the cortical changes associated with a combination intervention using bimanual massed practice training with somatosensory sti...
