My research is focused on understanding differences in neural plasticity when motor skill acquisition occurs in the presence of altered sensory inputs, and how lateralization of brain function and hand preference factor into this. Adaptive (beneficial) plasticity enhances motor learning and performance; while maladaptive (harmful) plasticity leads to faulty movement patterns, decreasing speed and accuracy of motor performance, and creating the potential for injury. In occupational, recreational or sporting contexts, we are often learning new motor skills while extraneous sensory stimuli such as vibration or pain are present. This Discovery Grant addresses how altered sensory inputs such as pain, influence whether movement induced plasticity is adaptive or maladaptive. Hand dominance or laterality is a model of lifelong use-dependent plasticity and this research also seeks to understand how motor control differences between the Dominant (Dom) and non-dominant (NonDom) limbs influences the potential for adaptive or maladaptive plasticity in response to motor training

我的研究重点是了解在感觉输入发生变化的情况下，运动技能获得时神经可塑性的差异，以及大脑功能和手的偏好因素如何对此产生影响。适应性(有益的)可塑性提高运动学习和表现；而非适应性(有害的)可塑性导致错误的运动模式，降低运动表现的速度和准确性，并造成伤害的可能性。在职业、娱乐或运动环境中，我们经常在学习新的运动技能时，会受到外界的感觉刺激，如振动或疼痛。这项发现奖励解决了改变的感觉输入，如疼痛，如何影响运动诱导的可塑性是适应的还是不适应的。手优势或偏侧是终生依赖使用的可塑性模型，本研究还试图了解优势(DOM)和非优势(非随机)肢体之间的运动控制差异如何影响对运动训练作出反应的适应性或非适应性可塑性的潜力
