Appropriate neuromuscular control and musculoskeletal responses of the thoracic and lumbar spine are essential to complete work and everyday tasks without injury. Labour injury statistics across Canada show low back pain (LBP) consistently represented the largest number of workplace related musculoskeletal disorder (WRMSD) claims (~18%) and had a total costs over $2 billion/year in 2014. If you consider the incidence of LBP increases with age, coupled to the Statistics Canada estimate that by 2027 30% of the Canadian population will be over 55 years, we must improve the knowledge about spine function now. The most far-reaching impact of my research program is the contribution to the fundamental knowledge of thoracic and lumbar spine musculoskeletal and neuromuscular control responses under conditions representing workplace risk factors. The foundational knowledge I generate deepens our understanding of the spine, which will reduce WRMSDs and costs to Canadians. ******My program examines the structure, control, and function of the thoracic and lumbar spine, to characterize the mechanisms underlying how healthy systems respond to a range of loading. I investigate the effects of age, sex, cognitive-motor task interference, and fatigue. The inclusion of the thoracic spine in my investigations is a novel aspect of my work, as is the novel method we developed to accurately quantify twist in-vivo. The novel method we developed to measure in-vivo spine twist has huge implications for rapidly increasing our understanding of this dangerous risk factor occurring in workplaces. Other methods are typical biomechanical approaches, including 3D motion capture for joint kinematics, muscle activation, and structural whole-body MRI. The empirical data and understanding of spine function generated from my program can be incorporated into existing lumbar spine models (expand to include thoracic spine impact) and can set parameters for in-vitro spine testing (to test injury mechanism theory). By reaching my research goals, developing a thriving research team (that includes high quality student trainees), and publishing in excellent journals, my research program will continue to make new discoveries and have a major impact on biomechanics and ergonomic fields. My program is the sole program worldwide to focus on thoracic spine mechanics, neuromuscular control, and interplay with lumbar spine, and twisting exposures to identify potential and understand existing spine injury mechanisms.

胸椎和腰椎适当的神经肌肉控制和肌肉骨骼反应对于无损伤地完成工作和日常任务至关重要。加拿大各地的工伤统计数据显示，腰痛(LBP)一直是工作场所相关肌肉骨骼疾病(WRMSD)索赔的最大数量(约18%)，2014年的总成本超过20亿美元/年。如果你考虑到LBP的发病率随着年龄的增长而增加，再加上加拿大统计局估计，到2027年，加拿大30%的人口将超过55岁，我们现在必须提高对脊柱功能的知识。我的研究计划最深远的影响是对胸腰椎、肌肉骨骼和神经肌肉控制反应的基础知识的贡献，这些反应在代表工作场所危险因素的条件下。我产生的基础知识加深了我们对脊椎的理解，这将减少加拿大人的WRMSD和成本。*我的程序检查胸椎和腰椎的结构、控制和功能，以表征健康系统如何对一系列负荷做出反应的潜在机制。我调查了年龄、性别、认知运动任务干扰和疲劳的影响。将胸椎包括在我的研究中是我工作的一个新方面，就像我们开发的在体内准确量化扭转的新方法一样。我们开发的测量体内脊柱扭转的新方法对于迅速提高我们对工作场所发生的这种危险危险因素的理解具有巨大的意义。其他方法是典型的生物力学方法，包括用于关节运动学的3D运动捕捉、肌肉激活和结构全身MRI。从我的程序中产生的经验数据和对脊柱功能的理解可以合并到现有的腰椎模型中(扩展到包括胸椎撞击)，并可以为体外脊柱测试设置参数(以测试损伤机制理论)。通过实现我的研究目标，发展一支蒸蒸日上的研究团队(包括高素质的学生实习生)，并在优秀的期刊上发表文章，我的研究计划将继续取得新的发现，并对生物力学和人体工程学领域产生重大影响。我的计划是全球唯一的计划，专注于胸椎力学、神经肌肉控制、与腰椎的相互作用以及扭转暴露，以确定潜在的和了解现有的脊柱损伤机制。
