BACKGROUND Since motor learning is a key component for stroke recovery, enhancing motor skill learning is a crucial challenge for neurorehabilitation. Transcranial direct current stimulation (tDCS) is a promising approach for improving motor learning. The aim of this trial was to test the hypothesis that dual-tDCS applied bilaterally over the primary motor cortices (M1) improves online motor sk...

Recovery of complex neural function after injury to the adult CNS is limited by minimal spontaneous axonal regeneration and/or sprouting from remaining pathways. In contrast, the developing CNS displays spontaneous reorganization following lesion, in which uninjured axons can develop new projections to appropriate target neurons and provide partial recovery of complex behaviours. Similar pathwa...

BACKGROUND Motor skill learning usually comprises "fast" improvement in performance within the initial training session and "slow" improvement that develops across sessions. Previous studies have revealed changes in activity and connectivity in motor cortex and striatum during motor skill learning. However, the nature and dynamics of the plastic changes in each of these brain structures during ...

We used a cognitive architecture (ACT-R) to explore the procedural learning of surgical tasks and then to understand the process of perceptual motor learning and skill decay in surgical skill performance. The ACT-R cognitive model simulates declarative memory processes during motor learning. In this ongoing study, four surgical tasks (bimanual carrying, peg transfer, needle passing, and suture ...

Objectives: Down syndrome (DS) is the most common multiple congenital anomaly syndrome associated with a developmental disability. Children with Down syndrome have delay in both motor and mental age. This study carried out to explore relationship between mental and motor age of children with DS. Methods: A cross-sectional study was conducted on 60 participants with DS (5 to 7 years old) usin...

background and objectives: motor development is considered as a part of the process of growth and development in which the child, firstly gains control over his own body function, and then utilizes it for interaction and manipulation with the environment. the aim of this study was to standardize of peabody developmental motor scale (pdms) in normal children aged 72 to 83 months living in tehran...

Humans have an exceptional ability to execute a variety of skilled movements. Researchers been long interested in understanding behavioral and neurophysiological basis human motor skill learning for advancing both fundamental neuroscientific knowledge clinical outcomes. However, despite decades work this field there is lack consensus about what meant by “skill” learning. With advent various tas...

OBJECTIVE In both clinical practice and research, motor delay is understood to be explained, at least in part, by intellectual abilities; however, no data are available to operationalize these criteria to guide clinical decision making. This study provides data on IQ and motor skills in children to answer 3 research questions concerning the relationship between IQ and motor skill: (1) Can motor...

Greater loss in structural integrity of the ipsilesional corticospinal tract (CST) is associated with poorer motor outcome in patients with hemiparetic stroke. Animal models of stroke have demonstrated that structural remodeling of white matter in the ipsilesional and contralesional hemispheres is associated with improved motor recovery. Accordingly, motor recovery in patients with stroke may r...
