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）：手动轮椅使用者出现上肢疼痛的风险很高。最近的研究和人体工程学文献指出了可以防止受伤的特定推进技术。该提案的具体目标是 1) 制定轮椅推进训练计划，最大限度地减少潜在的有害生物力学； 2）测试训练计划是否能引起推进生物力学的持久变化； 3) 确定在改进推进机制和随着时间的推移保持改进方面，向多媒体程序添加实时反馈是否比单独的多媒体程序更好。 PI 将通过由对照组、多媒体组以及多媒体和实时反馈组组成的纵向对照试验来实现这些目标。培训将持续三周，他们将跟踪科目三个月。多媒体培训将包括一个基于网络的视频，指导轮椅使用者使用适当的技术。实时反馈将使用力和力矩感应推圈直接向受试者显示生物力学。在两种速度条件下和间歇性间隔期间，监视器将提供轮椅推进过程中节奏、行程角度和速度中的一项或多项的实时反馈。动力学和运动学分析将用于确定目标变量以及推轮力以及关节力和力矩的训练效果。这项研究将深入了解改变长期轮椅使用者的轮椅推进生物力学的能力。在轮椅推进过程中最小化步频和最大化推动角度可能有助于最大程度地减少伤害，并且可能是减少 SCI 手臂疼痛的介入试验的第一步。
