Exercise and Monitoring With Post-Hospitalization Muscle Atrophy to Sustain Intrinsic Capacity and Strength

This condition, known as disuse muscle atrophy, poses a substantial challenge to the health and well-being of individuals, particular those hospitalized. To tackle this problem , the project focuses on a specific group of individuals particularly vulnerable to this issues: Veterans with chronic kidney disease (CKD). This disease affects a substantial population of over 500,000 Veterans, leading to a progressive decline in mobility, unfavorable changes in lean body mass, and heightened hospitalization rates. To comprehensively address this concern, the project indents to develop and implement assessment and intervention strategies tailored to the target cohort's needs. By concentrating on Veterans with CKD, the project seeks to generate approaches that can be widely applied to address muscle atrophy among individuals with similar conditions. To achieve this, the project twill commence by establishing a baseline cohort of Veterans with Stage 3 and 4 CKD at two distinct Veterans Affairs sites located in Denver and Baltimore. Upon enrollment, the Veterans muscles health will be assessed, encompassing various dimensions such as strength, lean muscle mass, muscle composition, mobility, and intrinsic capacity. This comprehensive evaluation will provide a snapshot of their pre-hospitalization muscle health. Subsequently, the enrolled Veterans will be closely monitored for at least two years. The project's approach involves conducting regular assessments of their muscle health every six months. Additionally, the participating Veterans will provide information about their strength and functional status every quarter, facilitated through a smartphone application. A particular noteworthy aspect of the project is its inclusion of a pragmatic rehabilitation intervention trail. Veterans who experience hospitalization during the study will have the opportunity to participate in this trial. They will be assigned to either a supervised flywheel strengthening exercise group or receive usual care over 16 weeks. This intervention trial aims to assess the effective ness of targeted exercise in mitigating the effects of disuse muscle atrophy post-hospitalization. The overarching design of the project encompasses three main objectives:

Aim 1: Identify effective muscle assessment sites for disuse muscle atrophy. Aim 2: Assess if standardized intrinsic capacity and physical resilience assessments predict hospital outcomes. The investigators anticipate that physical resilience scores will improve hospitalization and strength outcomes predictions.

Aim 3: Evaluate a supervised flywheel exercise program against usual care. Both groups are expected to improve, with the supervised group have better results.
