There are about 260 000 manual Wheelchair (WC) users in Canada. Due to many physical, social and environmental barriers, WC use is often associated to a sedentary lifestyle, physical deconditioning and decreased quality of life, leading to annual costs of more than 8 M$ due to morbidity. WC sports may reduce this spiral of physical inactivity. However, as everyday WC mobility causes secondary musculoskeletal impairment to half of the WC users due to a high and repetitive joint load, then WC sports need special attention because the joint load is even higher. Unfortunately, knowledge on WC sports biomechanics is scarce due to the unavailability of adequate measurement equipment. No current instrumented wheel can record propulsion kinetics during highly dynamic conditions such as WC sports. Moreover, no current WC simulator can reproduce controlled, realistic WC sports conditions or provide biofeedback to improve the users’ propulsion techniques. My long-term main objective is to design new technologies and generate new knowledge in WC sport biomechanics. During the next 5 years, the following specific objectives, which all focus on research in biomechanics and technologies related to wheelchair racing, will be addressed: Obj. 1: Design and validate two new instrumented racing wheels to record bilateral propulsion kinetics in real racing conditions, using the users’ own WCs, without adding significant weight or rolling resistance. Obj. 2: Design and validate an innovative wheelchair simulator to record racing kinematics, electromyography (EMG) and kinetics with the new wheel prototypes in a controlled and realistic laboratory environment, using the users’ own WCs. This simulator will make use of advanced force feedback, visuals and acoustics to provide an immersive racing environment to the users. Obj. 3: Analyze racing biomechanics and simulate the effect of different techniques on performance and joint load based on biomechanical acquisitions on the new simulator. Obj. 4: Create a real-time biofeedback system that estimates the joint dynamics in real time and that provides this variable as auditory, visual and force biofeedback to the users. This innovative work will allow full understanding of racing biomechanics and therefore maximize performance and reduce joint load. It will allow the testing of new prototypes of standard and sports wheelchairs in controlled and realistic conditions, allow research on the development of fatigue and injury and on the effects of biofeedback during WC training. It will also allow the formation of highly qualified personnel in the fields of WC sports technologies. In the future, this research program will allow the integration of personalized sports training into the rehabilitation process, benefiting the whole population of manual WC users and reducing the enormous costs related to physical inactivity.

加拿大大约有26万手动轮椅（WC）用户。由于许多身体，社会和环境障碍，WC的使用通常与久坐的生活方式相关，身体上的调解和改善的生活质量，导致由于发病率而导致的每年成本超过8 m $。 WC运动可能会减少这种身体不活动的螺旋。但是，由于WC移动性每天都会导致次级肌肉骨骼障碍，因为高度重复的关节负荷由于关节负载甚至更高，因此WC运动需要特别注意。 不幸的是，由于无法获得足够的测量设备，有关WC运动生物力学的知识很少。当前的仪表车轮无法在高度动态的条件下（例如WC运动）记录推进动力学。此外，当前的WC模拟器无法重现受控的，现实的WC运动条件或提供生物反馈以改善用户的推进技术。 我的长期主要目标是设计新技术，并在WC Sport Biomechanics中产生新知识。在接下来的五年中，将解决以下特定目标，这些目标都集中在与轮椅赛车相关的生物力学和技术研究上： OBJ。 1：设计和验证两个新的乐器赛车轮，以使用用户自己的WCS在实际赛车条件下记录双边推进动力学，而不会增加重量或滚动阻力。 OBJ。 2：设计和验证创新的轮椅模拟器，以使用用户自己的WCS在受控且逼真的实验室环境中使用新的轮子原型记录赛车运动学，肌电图（EMG）和动力学。该模拟器将利用先进的力量反馈，视觉效果和声学，为用户提供身临其境的赛车环境。 OBJ。 3：分析赛车生物力学，并基于生物力学采集对新模拟器对性能和关节负载的影响。 OBJ。 4：创建一个实时的生物反馈系统，该系统实时估算关节动力学，并为用户提供此变量作为听觉，视觉和强迫生物反馈。 这项创新的工作将使人们对赛车生物力学有充分的了解，从而最大程度地提高性能并减少关节载荷。它将允许在受控和现实的条件下测试标准和运动轮椅的新原型，从而研究疲劳和伤害的发展以及WC培训期间生物反馈的影响。它还将允许在WC体育技术领域的高素质人员形成。将来，该研究计划将允许将个性化的运动培训整合到康复过程中，从而使整个手动WC用户的人群受益，并降低与身体不活动相关的巨大成本。
