DESCRIPTION (provided by applicant): Manual wheelchair users are at high risk of developing upper limb pain. Recent research and ergonomics literature point to specific propulsion techniques that may prevent injury. The specific aims of this proposal are to 1) Develop wheelchair propulsion-training programs that minimize potential injurious biomechanics; 2) Test if the training programs can cause lasting changes in propulsion biomechanics; and 3) To determine if the addition of real time feedback to a multimedia program is better than a multimedia program alone at improving propulsion mechanics and maintaining improvements over time. The PIs will achieve these aims in a longitudinal controlled trial with a control group, a multimedia group, and a multimedia and real-time feedback group. Training will occur over three weeks and they will follow subjects for three months. The multimedia training will consist of a web-based video that instructs wheelchair users on appropriate technique. The real-time feedback will use a force and moment sensing pushrim to display biomechanics directly to the subjects. During two speed conditions and at intermittent intervals a monitor will provide real-time feedback on either one or a combination of cadence, stroke angle, and velocity during wheelchair propulsion. Kinetic and kinematic analysis will be used to determine training effectiveness both on the target variables and on pushrim forces and joint forces and moments. This study will provide insight into the ability to change wheelchair propulsion biomechanics among chronic wheelchair users. Minimizing cadence and maximizing push angle during wheelchair propulsion may help to minimize injuries and could be the first step in an interventional trial to reduce arm pain in SCI.

描述（由申请人提供）：手动轮椅使用者的高风险患上肢疼痛。最近的研究和人体工程学文献指出了可能预防伤害的特定推进技术。该提案的具体目的是1）制定轮椅推进训练计划，以最大程度地减少潜在的有害生物力学； 2）测试培训计划是否会导致推进生物力学的持续变化； 3）确定在多媒体程序中增加实时反馈是否比单独的多媒体计划更好，以改善推进力学并随着时间的推移维持改进。 PI将在对照组，多媒体组以及多媒体和实时反馈组的纵向对照试验中实现这些目标。培训将在三个星期内进行，他们将跟随受试者三个月。多媒体培训将由基于网络的视频组成，该视频指示轮椅用户使用适当的技术。实时反馈将使用力量和力矩感测推力直接向受试者展示生物力学。在两个速度条件下，在间歇间隔下，监视器将在轮椅推进期间对一个或组合的一个或组合提供实时反馈。动力学和运动学分析将用于确定目标变量，推杆力以及关节力和力矩的训练效果。这项研究将洞悉慢性轮椅使用者中改变轮椅推进生物力学的能力。在轮椅推进过程中最大程度地减少节奏和最大化推动角可能有助于最大程度地减少伤害，并且可能是介入试验的第一步，以减轻SCI的手臂疼痛。
