DESCRIPTION (provided by applicant): Independent mobility is a key contributor to the quality of life and social participation of an individual with a physical disability. With decreased mobility, there is usually an associated increased risk of social isolation, unemployment, and other health problems, such as obesity, cardiovascular disease, and pressure ulcers. Unimpaired individuals on fitness programs and athletes in training use instruments to measure their progress. Pedometers, for example, are widely used to measure walking distances for the purpose of monitoring physical activity levels and evaluating the attainment of physical activity recommendations. However, there are no commercial "pedometers" for individuals who use wheelchairs. Thus, they cannot objectively quantify levels of physical activity and detect incremental changes as a result of intervention. Researchers at the Human Engineering Research Laboratories have developed two generations of wheelchair dataloggers. These dataloggers have been successfully used to investigate the activity levels of consumers and compare usage among different types of wheelchairs. We have received several requests from research institutions, rehabilitation hospitals and clinics to purchase our second-generation dataloggers. The market appeal for wheelchair dataloggers has also been confirmed through feedback from users, clinicians, therapists, and wheelchair manufacturers and suppliers. In this proposal, we will further improve both our manual and powered wheelchair dataloggers. Improvements will encompass mechanical reliability, electronic updates and software features. It is critical that commercialization of wheelchair dataloggers be accelerated so that it can become more readily available as an outcome measure for researchers, clinicians, wheelchair manufacturers and suppliers, as they all strive to understand how wheelchairs or other related interventions affect mobility levels of users, or how mobility levels relate to other medical/physiological symptoms. This enhanced objective understanding facilitated by dataloggers will lead to early detection and intervention of mobility-induced problems, quantifiable intervention or prescription evaluation, and justification of wheelchairs provided.

描述（由申请人提供）：独立行动能力是身体残障人士生活质量和社会参与的关键因素。随着流动性的下降，社会孤立、失业和其他健康问题（如肥胖、心血管疾病和压疮）的风险通常会增加。 参加健身计划的未受损伤的个人和训练中的运动员使用仪器来衡量他们的进步。例如，计步器被广泛用于测量步行距离，以监测身体活动水平并评估身体活动建议的实现情况。然而，对于使用轮椅的人来说，还没有商业“计步器”。因此，他们无法客观地量化身体活动水平并检测干预导致的增量变化。 人类工程研究实验室的研究人员开发了两代轮椅数据记录器。这些数据记录器已成功用于调查消费者的活动水平并比较不同类型轮椅的使用情况。我们收到了来自研究机构、康复医院和诊所的多个购买我们第二代数据记录仪的请求。用户、临床医生、治疗师以及轮椅制造商和供应商的反馈也证实了轮椅数据记录仪的市场吸引力。在本提案中，我们将进一步改进我们的手动和电动轮椅数据记录器。改进将包括机械可靠性、电子更新和软件功能。 至关重要的是，加速轮椅数据记录仪的商业化，以便研究人员、临床医生、轮椅制造商和供应商更容易将其作为结果衡量标准，因为他们都在努力了解轮椅或其他相关干预措施如何影响用户的行动水平，或者活动水平与其他医疗/生理症状的关系。数据记录器促进的这种增强的客观理解将有助于及早发现和干预由行动引起的问题、可量化的干预或处方评估以及提供轮椅的合理性。
