Cortical interhemispheric interactions in motor control are still poorly understood and it is important to clarify how these depend on inhibitory/facilitatory limb movements and motor expertise, as reflected by limb dominance. Here we addressed this problem using functional magnetic resonance imaging (fMRI) and a task involving dominant/nondominant limb mobilization in the presence/absence of c...

Peters (J Motor Behav 21:151-155, 1989; Interlimb coordination: neural, dynamical and cognitive constraints, Academic, Orlando, pp 595-615, 1994) suggested that expressions of handedness in bimanual coordination may be reflections of an inherent attentional bias. Indeed, previous results indicated that focusing attention on one of the limbs affected the relative phasing between the limbs in a m...

Background: Osteoarthritis (OA) is second most common degenerative arthritis with 56.6% affection in rural areas where as 32.6% urban India.Dominant lower limb the leg used to manipulate objects or lead out movement. Primary predisposing factor of wear and tear which might correlate dominance limb. Methodology: Total 180 subjects were screened, 61 bilateral osteoarthritis 40 unilateral selected...

BACKGROUND Focality of onset of amyotrophic lateral sclerosis (ALS) is not understood. Attempts to implicate physical exercise in the aetiology of ALS have provided inconsistent results. If physical use of a limb were important in defining the site of onset, then handedness might be expected to influence the side of upper limb-onset disease and footedness likewise in lower limb-onset ALS. MET...

Mounting evidence suggest that the right-hemisphere (RH) has a relative advantage, over the left-hemisphere (LH), in mediating social intelligence - identifying social stimuli, understanding the intentions of other people, awareness of the dynamics in social relationships, and successful handling of social interactions. Furthermore, a review and synthesis of the literature suggest that pro-soci...

This study was designed to differentiate between two models of motor lateralization: "feedback corrections" and dynamic dominance. Whereas the feedback correction hypothesis suggests that handedness reflects a dominant hemisphere advantage for visual-mediated correction processes, dynamic dominance proposes that each hemisphere has become specialized for distinct aspects of control. This model ...

Content: Electromyography (EMG) is a recording of muscles electrical activity and is useful for mechanism study. In Exercise and Sport Science, mechanism of dominance and non-dominance limb activity is recently a focus area. Objective: The aim of this study is to observe the muscle electrical activity of soccer players’ dominant and non-dominant leg. Design: Cross-sectional study. Setting: Dist...

The evolution of the appendages during fin-to-limb transition has been extensively studied, yet majority studies focused on skeleton and fossil record. Whereas anatomy appendicular musculature changes in muscular architecture remain largely unstudied, may provide important new insights. is associated with appearance a mode locomotion shift from pectoral to pelvic dominance. Here, we propose way...
