Article Abstract
Movement preparation of bimanual asymmetric movements takes more time than bimanual symmetric movements in choice reaction-time conditions. This bimanual asymmetric cost may be caused by increased processing demands on any stage of movement preparation. The authors tested the contributions of each stage of movement preparation to the asymmetric cost by using the additive factors method. This involved altering the stimulus contrast, response compatibility, and response complexity. These manipulations changed the processing demands on stimulus identification, response selection, and response programming, respectively. Any manipulation with a larger reaction time cost than control suggests that stage contributes to the bimanual asymmetric cost. The bimanual asymmetric cost was larger for incompatible stimuli, which supports that response selection contributes to the bimanual asymmetric cost.

Effect of aging on the visuomotor control during continuous bimanual movement.
Front Aging Neurosci

Department of Mechanical and Aerospace Engineering, University of Central Florida, Orlando, FL, United States.
Introduction: Skilled bimanual coordination is an essential component of activities of daily living that relies on complex interactions between the limbs, yet how age-related changes impact asymmetries in visuomotor control during these tasks remains largely unknown. In the present study, we examined both motor performance and visual attention distribution in non-rhythmic continuous bimanual tasks and investigated the effect of aging.
Methods: Twelve right-handed young adults (YA) and twelve right-handed older adults (OA) performed a bimanual tracking task in which each hand controlled a cursor using a robotic device to track the upward movement of a horizontal target line simultaneously and independently.
Developmental changes in independent bimanual coordination: evidence from the circles-lines coupling task in children aged 5-13 years.

Introduction: Bimanual coordination, particularly the ability to perform independent and simultaneous asymmetric movements with both hands, is essential for many daily activities and develops throughout childhood. However, its developmental trajectory remains unclear. This study investigated age-related changes in bimanual coordination using the bimanual circles-lines coupling (BC) task and explored its relationship with fine motor skills in children aged 5 to 13 years.

Background: Cerebral Palsy (CP) is the most common childhood-onset motor disability. Play-based early intensive manual therapies (EIMT) is an evidence-based practice to improve long-term hand function particularly for children with asymmetric hand use due to CP. For children under two years old, this therapy is often delivered by caregivers who are coached by occupational therapists (OTs).

Many motor skills require precise coordination between the arms to accomplish. The use of transcranial direct current stimulation (tDCS) has helped to reveal hemispheric contributions to bimanual skills. In this study, three bilateral montages were used to explore hemispheric contributions to a rhythmic bimanual skill: anode left M1/cathode right M1 (LARC), anode right M1/cathode left M1 (RALC), and sham.

Instituto de Microcirugia Ocular, Barcelona, Spain .
Purpose: To present a new technique for lens explantation, involving intraocular lens (IOL) cleavage in the vitreous chamber using two forceps and successive removal from the anterior chamber.
Methods: Retrospective monocentric analysis of 10 eyes affected by IOL subluxation/luxation who underwent IOL explantation and 23-G vitrectomy. After separating the capsular bag rests from the IOL using the vitrectomy probe, serrated forceps were used to grab the IOL, while microscissors performed an "initiation" cut at the midpoint of the lens plate.
