Impact of control mechanisms and tissue morphology on upper extremity loading

与工作有关的疾病每年使加拿大人损失数十亿美元。非常需要充分了解上肢（肩、臂和手）组织在工作中变得超负荷的机制。这些机制之所以有趣和复杂，是因为它们是在很长一段时间内发展起来的，因此很难确定造成损害的原因。这些疾病涉及肌肉、结缔组织（例如网球肘、肌腱炎）和周围神经（例如腕管综合征）。在了解这些疾病并使工人的工作更安全之前，必须表征健康组织如何对一系列负荷条件做出反应的机制。我的研究计划，评估健康组织对各种姿势的反应，负载，干扰任务，疲劳（局部和中央），以及衰老。我们还必须了解解剖学和运动控制之间的复杂相互作用。

Work-related disorders cost Canadians billions of dollars every year. There is a great need to fully understand the mechanisms by which tissues of the upper extremity (shoulder, arm, and hand) become overloaded at work. What makes these mechanisms interesting and complex is that they develop over a long period of time, making it difficult to pinpoint what caused the damage. These disorders involve muscle, connective tissue (e.g. tennis elbow, tendinitis), and peripheral nerves (e.g. carpal tunnel syndrome). Before understanding these disorders and making jobs safer for workers, it is essential to characterize the mechanisms underlying how healthy tissues respond to a range of loading conditions. My research program that evaluates the response of healthy tissues to a variety of postures, loads, interfering tasks, and fatigue (localized and central), as well as aging. We must also understand the complex interactions between anatomy and the control of movement.
