The corpus callosum (CC) is the largest white matter tract in the brain. It enables interhemispheric communication, particularly with respect to bimanual coordination. Here, we use diffusion tensor imaging (DTI) in healthy humans to determine the extent to which structural organization of subregions within the CC would predict how well subjects learn a novel bimanual task. A single DTI scan was...

PURPOSE Development of objective criteria and optimum training protocols are priorities for robotic laparoscopy. However, studies that have attempted to objectify learning have been limited due to lack of task complexity and absence of comparisons between experts and novices. Our aim was to address these limitations and assess proficiency in robotic laparoscopy using bimanual inanimate tasks. ...

INTRODUCTION Haptic virtual reality (VR) has revolutionized the skill acquisition in dentistry. The strength of the haptic VR system is that it can automatically record the outcome and associated kinematic data on how each step of the task is performed, which are not available in the conventional skill training environments. The aim of this study was to assess skill acquisition in endodontics a...

[Purpose] In this study, we examined effects of modified constraint-induced movement therapy (m-CIMT) and functional bimanual training, when applied to a patient with incomplete spinal cord injury, on upper extremity function and daily activities. [Subject and Methods] One patient, diagnosed with C4 incomplete spinal cord injury, underwent physical therapy with constraint-induced movement thera...

CONTEXT Rehabilitation for children with congenital hemiplegia to improve function in the impaired upper limb and enhance participation may be time-consuming and costly. OBJECTIVES To systematically review the efficacy of nonsurgical upper-limb therapeutic interventions for children with congenital hemiplegia. METHODS The Cochrane Central Register of Controlled Trials, Medline, CINAHL (Cumu...

STUDY OBJECTIVE External cricoid and thyroid cartilage manipulations are commonly taught to facilitate laryngeal view during intubation. We compare the laryngeal views during laryngoscopy with 4 manipulations (no manipulation, cricoid pressure, backward-upward-rightward pressure [BURP], and bimanual laryngoscopy) to determine the method that optimizes laryngeal view. METHODS This was a random...

Perceptual processes play an important role in motor learning. While it is evident that visual information greatly contributes to learning new movements, much less is known about provision of prescriptive proprioceptive information. Here, we investigated whether passive (proprioceptively-based) movement training was comparable to active training for learning a new bimanual task. Three groups pr...

Motor training results in performance improvement. It is not yet fully understood the extent to which functional improvement is reflected in changes in brain structure. To investigate the presence and degree of structural brain plasticity induced by long-term bimanual motor activity, we studied 17 right-handed professional typists with average duration of typing practice of 11 years. Using opti...

the aim of this study was to compare the effects of cognitive-attentional and cognitive-motor load on the performance of bimanual coordination skill. 31 female students (mean age 25+2 years) from shahid beheshti university attending were selected voluntarily and divided randomly into three groups: single group (n=11), cognitive group (n=10) and cognitive-motor group (n=10). single group partici...

Aging is associated with deterioration of skilled manual movement. Specifically, aging corresponds with increased reaction time, greater movement duration, segmentation of movement, increased movement variability, and reduced ability to adapt to external forces and inhibit previously learned sequences. Moreover, it is thought that decreased lateralization of neural function in older adults may ...
