The present study examines the effects of a four-week training session in a pegboard task on uniand bimanual performance. Of particular interest was whether practice transfer from the trained to the untrained hand takes place. Twenty-five consistently right-handed subjects were trained to perform the task with the dominant hand, or the subdominant hand, or with both hands. After this training, ...

The issue of handedness has been the topic of great interest for researchers in a number of scientific domains. It is typically observed that the dominant hand yields numerous behavioral advantages over the non-dominant hand during unimanual tasks, which provides evidence of hemispheric specialization. In contrast to advantages for the dominant hand during motor execution, recent research has d...

OBJECTIVE To determine reliability of maximal grip strength, muscle coordination and muscle endurance. To compare these parameters in young adults with unilateral cerebral palsy and healthy subjects. To evaluate the correlation of these variables with functional activities. SUBJECTS Twenty-six healthy subjects and 26 young adults with unilateral cerebral palsy recruited from a cohort study in...

Amputation of the dominant hand forces patients to use the nondominant hand exclusively, including for tasks (e.g., writing and drawing) that were formerly the sole domain of the dominant hand. The behavioral and neurological effects of this chronic forced use of the nondominant hand remain largely unknown. Yet, these effects may shed light on the potential to compensate for degradation or loss...

Co-ordinated bi-manual actions form the basis for many everyday motor skills. In this review, the internal model approach to the problem of bi-manual co-ordination is presented. Bi-manual coordinative tasks are often regarded as a hallmark of complex action. They are often associated with object manipulation, whether the holding of a single object between the two hands or holding an object in e...

[Purpose] Eye-hand coordination declines with age, but physical activity is known to slow down the degeneration. Playing mahjong involves lots of eye-hand coordination. The objective was to investigate the relationship between playing mahjong and eye-hand coordination in older adults using a fast finger-pointing paradigm. [Subjects and Methods] Forty-one community dwelling older adults aged six...

Is there any difference between matching the position of the hands by asking the subjects to move them to the same spatial location or to mirror-symmetric locations with respect to the body midline? If the motion of the hands were planned in the extrinsic space, the mirror-symmetric task would imply an additional challenge, because we would need to flip the coordinates of the target on the othe...

background: hand grip strength (hgs) is a reliable indicator of peripheral muscle strength. although, numerous studies have investigated the strength of hand grip; little attention has been given to coronary artery disease (cad) patients, exploring the relationship between hgs and myocardial oxygen consumption (mvo2) index. the current study aimed to evaluate the interaction between hgs and mvo...

Purpose Muscle strength is often higher when measured on the dominant hand than non-dominant hand, and there are reports of differences in mortality rates between left-handed right-handed people Korean population. Therefore, it necessary to longitudinally investigate effect grip rates. Methods Data from Longitudinal Study Aging (KLoSA) 2006 2016 were assessed 9,196 research subjects included. T...
