Limb movements bring about changes in the activity of our sensory systems. When lifting a carton of milk, receptors in the muscles help determine if the carton is as full as expected. Subsequently, moving the milk carton to pour the milk arguably relies more on vision. As such, most reaching movements can be segregated into phases. The research programme led by Dr. Tremblay will assess the extent to which the brain relies on the different senses to control the different phases of voluntary movements.***In three series of studies, information provided to the eyes and muscles will be manipulated during different portions of the movement. The limb trajectories and endpoints will be analysed to determine the contribution of both sensory modalities. In another set of studies, participants will be asked to make perceptual judgments about their endpoint accuracy, after trials where information provided to the eyes and muscles will be perturbed. Because the manipulations and perturbations will be provided at different portions of the trajectory, it will be possible to assess the contribution of sensory information from the eyes and muscles to control the different phases of voluntary movements.***Knowing how humans rely on sensory information from the eyes and the muscles during the different portions of voluntary movements is critical to build efficient training programs (e.g., sports). Establishing this fundamental knowledge is imperative before making informed decisions about the design of training and rehabilitation programs. For example, a growing proportion of the Canadian population needs sensorimotor therapy. As the case for coaching sports, rehabilitation is not always effective. In the case of unsuccessful rehabilitation, ineffective protocols incur additional health care costs, starting with caregiving services for activities of daily living. While many other practical reasons can be given to justify this research program (e.g., designing human machine interfaces), it remains rather puzzling that we know how to send a man on the moon but yet don't know how we push the launch button.**

肢体运动会导致我们的感觉系统活动发生变化。当举起一盒牛奶时，肌肉中的感受器有助于确定纸盒是否像预期的那样满。随后，移动牛奶盒来倒牛奶可以说更多地依赖于视觉。因此，大多数伸展运动可以分为几个阶段。由 Tremblay 博士领导的研究项目将评估大脑依赖不同感官来控制随意运动不同阶段的程度。***在三个系列的研究中，提供给眼睛和肌肉的信息将在运动的不同部分。将分析肢体轨迹和端点，以确定两种感觉方式的贡献。在另一组研究中，在提供给眼睛和肌肉的信息受到干扰的试验之后，参与者将被要求对其终点准确性做出感知判断。由于操纵和扰动将在轨迹的不同部分提供，因此可以评估来自眼睛和肌肉的感觉信息的贡献，以控制随意运动的不同阶段。***了解人类如何依赖感觉信息在随意运动的不同部分中，来自眼睛和肌肉的信息对于建立有效的训练计划（例如运动）至关重要。在就培训和康复计划的设计做出明智的决定之前，必须建立这些基础知识。例如，越来越多的加拿大人口需要感觉运动治疗。与体育教练的情况一样，康复并不总是有效。如果康复不成功，无效的方案会产生额外的医疗保健费用，首先是日常生活活动的护理服务。虽然可以给出许多其他实际理由来证明该研究计划的合理性（例如，设计人机界面），但令人困惑的是我们知道如何将人送上月球，但不知道如何按下发射按钮。 **
