Practice of a given physical activity is known to improve the motor skills related to this activity. However, whether unrelated skills are also improved is still unclear. To test the impact of physical activity on an unpracticed motor task, 26 young adults completed the international physical activity questionnaire and performed a bimanual coordination task they had never practiced before. Resu...

We review the properties of coordinated rhythmic bimanual movements and previous models of those movements. Those models capture the phenomena but they fail to show how the behaviors arise from known components of the perception/ action system and in particular, they do not explicitly represent the known perceptual coupling of the limb movements. We review our own studies on the perception of r...

During bimanual load lifting, the brain must anticipate the effects of unloading upon the load-bearing arm. Little is currently known about the neural networks that coordinate these anticipatory postural adjustments. We measured neuromagnetic brain activity with whole-head magnetoencephalography while participants performed a bimanual load-lifting task. Anticipatory adjustments were associated ...

Abstract Introduction: The cerebral palsy and brachial plexus injury may cause asymmetry in the use of upper limbs (UL). This condition requires early treatment to reduce impact child's life; therefore, several proposed interventions aim increase their functional independence. Constraint-Induced Movement Therapy (CIMT) Hand-Arm Bimanual Intensive (HABIT) have been widely considered effective im...

Children with unilateral cerebral palsy (CP) have been shown to improve their motor performance with sufficient practice. However, little is known about how they learn goal-oriented tasks. In the current study, 21 children with unilateral CP (age 4-10 years old) and 21 age-matched typically developed children (TDC) practiced a simple bimanual speed stack task over 15 days of practice. Both grou...

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...

Purpose: Poor bimanual performance is usually a major functional impairment for children with unilateral cerebral palsy (CP). This study was performed to examine the reliability and validity of Turkish version Caregiver Functional Use Survey (CFUS), which assesses manual function CP.Methods: Fifty CP their parents were included in study. The test-retest assessed using Intraclass Correlation Coe...

Although strong motor coordination in intrinsic muscle coordinates has frequently been reported for bimanual movements, coordination in extrinsic visual coordinates is also crucial in various bimanual tasks. To explore the bimanual coordination mechanisms in terms of the frame of reference, here we characterized implicit bilateral interactions in visuomotor tasks. Visual perturbations (finger-c...

28 Bilateral movement rehabilitation is gaining popularity as an approach not only to improve the recovery 29 of bimanual function, but also of unilateral motor tasks. While the neural mechanisms mediating the 30 transfer of bilateral training gains into unimanual contexts are not fully understood, converging evidence 31 from behavioural, neurophysiological and imaging studies suggests that bim...
