 DESCRIPTION (provided by applicant): Project Summary/Abstract Over 1 million Americans currently live with lower limb amputations and the number is expected to more than double by 2050. More than 80% of all lower limb amputations result from vascular complications due to diseases such as severe diabetes mellitus and/or severe peripheral artery disease, known as dysvascular amputation. The population of Veterans with dysvascular lower limb amputation is growing, and high levels of mortality and disability highlight the significance of identifying ways to optimize physical rehabilitation. The dysvascular amputation population is characterized by: 1) low levels of physical activity and 2) high rates of disability. Such poor physical activity and disability outcomes are likely linked to chronic physical activity behaviors that Veterans adopt before dysvascular lower limb amputation and carry over after amputation. Therefore, the primary aim of this pilot study is to determine the feasibility of using a physical-activity behavior-change (PABC) intervention for increasing physical activity and reducing disability in Veterans 1-5 years following dysvascular lower-limb amputation. This pilot study will be the first to assess the feasibility of using a PABC intervention for older adult Veterans with dysvascular amputation. The PABC intervention is three months in duration. Testing will occur at baseline (pre-intervention), three months (end of intervention), and six months. Feasibility will be determined using measures of 1) participant retention, 2) dose goal attainment, 3) participant acceptability, 4) safety, and 5) initial effect size. Effect size will be based on the outcome measures of accelerometer-based physical activity and self-report disability using the Late-Life Function and Disability Index. This pilot study addresses an understudied and growing population of older Veterans characterized by complex health conditions. The outcome will significantly advance current research by providing critical feasibility data related to improving the chronic low physical activity and high levels of disability experienced by this population of older Veterans.

 描述（由申请人提供）： 项目摘要/摘要目前有超过100万美国人的下肢截肢，预计到2050年，该数量预计将超过两倍。所有下肢截肢的80％以上是由于严重的糖尿病和/或严重的外周动脉疾病（称为血管血管截肢的严重糖尿病）引起的血管并发症所致。血管下肢截肢的退伍军人人口正在增长，高水平的死亡率和残疾强调了确定优化身体康复方法的重要性。血管截肢群体的特征是：1）体育活动的低水平和2）较高的残疾率。如此不佳的身体活动和残疾结果可能与退伍军人在血管下肢截肢之前采用的慢性体育锻炼行为有关，并在截肢后延续。因此，这项试验研究的主要目的是确定使用身体活跃行为变化（PABC）干预以增加体育活动并减少血管下血管下LIMB截肢后1 - 5年的残疾的可行性。这项试点研究将是第一个评估使用PABC干预术的可行性的，该研究可为血管血管截肢的老年退伍军人使用。 PABC干预持续时间为三个月。测试将在基线（干预前），三个月（干预结束）和六个月时进行。可行性将使用1）参与保留率的度量确定，2）剂量目标尝试，3）参与可接受性，4）安全性和5）初始效果大小。效应大小将基于使用晚期功能和残疾指数的基于加速度计的体育活动和自我报告残疾的结果度量。这项试点研究涉及以复杂健康状况为特征的老年退伍军人的理解和不断增长的人口。该结果将通过提供与改善慢性体育锻炼和高水平的老年退伍军人所经历的重要的可行性数据，从而显着推动当前的研究。
