Details and patient eligibility

About

Frailty is common in patients with end-stage liver disease. It's characterized by reduced strength, low endurance and reduced physical function. While exercise intervention can improve frailty in geriatric patients without liver disease, whether or not exercise intervention can improve frailty in liver transplant candidates remains unknown.

Full description

The long-term goal is to better understand how exercise impacts frailty in order to identify treatments that can improve both patient-oriented outcomes and access to liver transplantation for end-stage liver disease patients. The specific objective of this proposal is to generate pilot feasibility data required for future multicenter R01 application to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) which will test the novel central hypothesis that exercise improves frailty and lessens waiting-list mortality. Additionally, another goal of the study is to establish an optimal frailty tool for liver transplant candidates.

Exercise intervention
Experimental group
Description:
Private supervised strength training exercise (e.g., body weight or dumbbell exercises) will occur in the Cancer Center Exercise Medicine Unit or the Hershey Center for Applied Research (HCAR) two days a week. In addition, subjects will be instructed to exercise on their own, at home, three days a week doing 30 minutes of moderate intensity aerobic exercise (e.g., walking at 45-55% maximum heart rate determined by the formula max heart rate = 220bpm - 0.64\*age in years).
Treatment:
Behavioral: Exercise intervention
Control
No Intervention group
Description:
Subjects in the control condition will be instructed to continue their medical care at the discretion of their treating medical professional and to maintain their current exercise level. Weekly phone calls will be performed to ensure adherence to the protocol (no changes in activity). Subjects will report to Penn State on a monthly basis for interim history and physical to confirm self-reports. Subjects will also be given a FitBit ChargeHR3 and downloaded data review will be performed monthly at the in-person visits.
