Quad-Rider Accessible Handcycle

描述(由申请人提供)：体力活动可以通过减缓或逆转生理功能来改善脊髓损伤和疾病(SCI/D)患者的健康和生活质量 减少，降低心血管疾病和糖尿病的风险因素，改善心理健康状况和独立性，并促进日常活动的有效表现。不幸的是，缺乏健身和娱乐设备是SCI/D患者参与增进健康的健身活动的主要障碍之一，而在C5-C8四肢瘫痪患者中，获得体育活动的机会极其有限。在这个第一阶段的项目中，我们将创建一种名为Quad-Rider的刹车和变速器换挡机构，使手功能受限的个人能够安全地操作手轮车。InvoTek工程师将创造四个原型四轮马车，使C5-C8四肢瘫痪的车手能够安全地推动、驾驶和停止使用手臂、肩膀和手腕肌肉，这些肌肉在SCI/D水平上仍然功能完好。湖滨基金会的健康、健身和娱乐专家将进行两次为期六周的干预，每次干预三名四肢瘫痪患者，以评估与使用四轮马车相关的生理和心理社会结果。我们的评估计划将：1.确保设计对我们的目标人群安全有效，2.确保C5-C8 SCI/D参与者可以安全地操作Quad-Rider，3.衡量骑手的健康益处。

DESCRIPTION (provided by applicant): Physical activity may improve the health and quality of life of people with spinal cord injury and disease (SCI/D) by slowing or reversing physiological decline, lowering risk factors for cardiovascular disease and diabetes, improving mental health status and independence, and promoting the efficient performance of daily activities. Unfortunately, lack of access to fitness and recreation equipment is one of the primary barriers to participating in health-enhancing fitness activities for people with SCI/D, and among individuals with C5-C8 tetraplegia, access to physical activity is extremely limited. During this Phase 1 project, we will create a brake and derailleur gear-changing mechanism named Quad-Rider that enables individuals with limited hand function to safely operate a handcycle. InvoTek engineers will create four prototype Quad-Riders that enable riders with C5- C8 tetraplegia to safely propel, steer, and stop using arm, shoulder, and wrist musculature, which are still functionally intact at this level of SCI/D. Health, fitness, and recreation experts at the Lakeshor Foundation will conduct two six-week interventions, each with three persons who have tetraplegia, to assess physiological and psychosocial outcomes associated with using Quad-Rider. Our evaluation plan will: 1. ensure that the design is safe and effective for our target population, 2. ensure that participants with C5-C8 SCI/D can safely operate Quad-Rider, and 3. measure the health benefits to riders.
