Aging, visual information, and adaptation to task asymmetry in bimanual force coordination.
This study investigated the coordination and control strategies that the elderly adopt during a redundant finger force coordination task and how the amount of visual information regulates the coordination patterns. Three age groups (20-24, 65-69, and 75-79 yr) performed a bimanual asymmetric force task. Task asymmetry was manipulated via imposing different coefficients on the finger forces such...
متن کاملConstraints on Coordination Intrinsic dynamics, behavioral information and asymmetry in bimanual rhythmic coordination
Rhythmic interlimb coordination arises from the interaction of intrinsic dynamics and behavioral information, i.e., intention, memory and/or external information specifying the required coordination pattern. This study investigates the influence of the content of memorized behavioral information on coordination in musically experienced and inexperienced subjects. These groups are hypothesized t...
متن کاملBimanual coordination and aging: neurobehavioral implications.
We investigate whether aging leads to global declines in discrete and continuous bimanual coordination tasks thought to rely on different control mechanisms for temporal coupling of the limbs. All conditions of continuous bimanual circle drawing were associated with age-equivalent temporal control. This was also true for discrete simultaneous tapping. Older adults' between-hand coordination def...
متن کاملModeling constraints to redundancy in bimanual force coordination.
This study investigated the interactive influence of organismic, environmental, and task constraints on the organization of redundant force coordination patterns and the hypothesis that each of the three categories of constraints is weighted based on their relative influence on coordination patterns and the realization of the task goal. In the bimanual isometric force experiment, the task const...
متن کاملGrip force coordination during bimanual tasks in unilateral cerebral palsy.
AIM The aim of the study was to investigate coordination of fingertip forces during an asymmetrical bimanual task in children with unilateral cerebral palsy (CP). METHOD Twelve participants (six males, six females; mean age 14y 4mo, SD 3.3y; range 9-20y;) with unilateral CP (eight right-sided, four left-sided) and 15 age-matched typically developing participants (five males, 10 females; mean ...
