DESCRIPTION (provided by applicant): People with mobility disabilities are at greater risk than the general population for incurring health problems such as pressure sores, urinary tract infections, high blood pressure, diabetes, and obesity. Many of these conditions are preventable through behavior and lifestyle changes. In particular, exercise and physical activity are widely recognized as having substantial health benefits, and recent evidence suggests that people with disabilities experience the same physiologic response to exercise as the general population. Nonetheless, nearly three-fourths of those with disabilities report being entirely sedentary or not active enough to achieve health benefits--largely due to barriers that are specifically related to the disability as well as those faced by the general population. This proposed randomized-controlled trial will test the effectiveness of a behavioral intervention to promote physical activity adoption and maintenance among people with mobility impairments. One-hundred eighty wheelchair users will be randomly assigned to an intensive six-month, home-based intervention or a minimal-contact control group and will be followed for another six months after the intervention ends. In this study, we aim to assess: (1) the effectiveness of the intervention for promoting physical activity adoption and maintenance, (2) the physical and psychosocial effects of the intervention, and (3) the complex interplay of factors that influence the effectiveness of the intervention. It is hypothesized that the experimental group will engage in more minutes of cardiovascular activity at 12 weeks, maintain higher rates of physical activity at 26 and 52 weeks, have larger improvements in strength and cardiovascular endurance, have larger improvements in perceived function and participation, and have larger improvements in exercise self-efficacy, well being, quality of life, and depressive symptoms than the control group. In addition, various hypotheses will examine the way in which barriers to exercise, exercise self-efficacy, and disability-related exacerbations operate; that is whether they have simple additive effects or operate in more complex ways as mediators (i.e., have indirect effects) or moderators (i.e., have interactive effects). Data collected from this study will yield unique and important evidence regarding strategies to promote physical activity among wheelchair users, as well as specific effects of physical activity on the physical and psychosocial health, function, and participation of community-dwelling wheelchair users.

描述（由申请人提供）：行动障碍人士比一般人群面临更大的健康问题风险，如压疮、尿路感染、高血压、糖尿病和肥胖。其中许多疾病是可以通过改变行为和生活方式来预防的。特别是，运动和体力活动被广泛认为对健康具有重大益处，最近的证据表明，残疾人对运动的生理反应与普通人群相同。尽管如此，近四分之三的残疾人表示完全久坐或活动不够，无法获得健康益处，这主要是由于与残疾特别相关的障碍以及普通人群面临的障碍。这项拟议的随机对照试验将测试行为干预对于促进行动障碍人士采用和维持身体活动的有效性。一百八十名轮椅使用者将被随机分配到为期六个月的居家强化干预组或最少接触对照组，并在干预结束后再进行六个月的跟踪调查。在本研究中，我们的目标是评估：(1) 促进身体活动采用和维持的干预措施的有效性，(2) 干预措施的身体和心理社会影响，以及 (3) 影响有效性的因素的复杂相互作用的干预。假设实验组在第 12 周时将进行更多分钟的心血管活动，在第 26 周和第 52 周时保持较高的体力活动率，在力量和心血管耐力方面有较大的改善，在感知功能和参与方面有较大的改善，并且与对照组相比，参与者在运动自我效能、幸福感、生活质量和抑郁症状方面有更大的改善。此外，各种假设将研究运动障碍、运动自我效能和残疾相关恶化的运作方式；也就是说，它们是否具有简单的累加效应，还是以更复杂的方式作为中介（即具有间接效应）或调节剂（即具有交互效应）发挥作用。从这项研究中收集的数据将产生关于促进轮椅使用者身体活动的策略的独特而重要的证据，以及身体活动对社区轮椅使用者的身体和心理社会健康、功能和参与的具体影响。
