简要总结
The investigators will conduct a pilot study to determine whether home-based exercise is an effective intervention to improve decreased physical function in kidney transplant candidates. The investigators will determine if home-based exercise improves frailty parameters and SPPB scores. The investigators will also determine if home-based exercise improves health-related quality of life (HRQOL), physical activity, and adverse clinical outcomes, including hospitalizations.
详细描述
Screening and Recruitment:
Potential participants will be identified from dialysis units, nephrology clinics, primary care clinics, or kidney transplant clinics at Baylor College of Medicine. Patients who express interest in the study will go through the informed consent process with a member of the study team, and patients wishing to participate in the study will complete written consent. If patients have not had frailty and SPPB testing within the two weeks prior to consent, the study team member will perform frailty and SPPB testing at baseline in a supervised setting. Patients who are not frail or pre-frail and have a SPPB score > 10 will be ineligible for study participation.
Exercise Intervention:
Participants will be provided with a pedal exerciser, resistance bands, and exercise pamphlets. Participants will be asked to complete an 8-week home-based exercise program with a focus on the core components of physical activity counseling and exercise training according to guidelines from the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation. Participants will receive an individualized exercise prescription. Recommended aerobic exercises will include arm and/or leg ergometry using a pedal exerciser, and recommended resistance training will include resistance bands. During the program, participants will receive weekly semi-scripted phone calls from an exercise physiologist and gradual increases in the volume of physical activity will be recommended over time. Participants will be asked to log information regarding their exercise sessions.

结局指标
主要结局
Change in Short Physical Performance Battery Score
时间窗: 8 weeks of home-based exercise
The Short Physical Performance Battery is a composite measure which includes component tests of balance, gait speed, and chair stand time. Participants receive a score of 0-4 for each of the 3 component tests with lower scores indicating worse physical function. Component scores are then summed providing a total score of 0-12 with lower scores again indicating worse physical function.
