Virtually Supervised Exercise for Kidney Transplant Candidates

This study is examining whether a virtually supervised exercise program can improve physical function in persons who are awaiting kidney transplant. The investigators will compare the results to a similar group of persons who receive a health education program.

Study Overview

• Status: Active, not recruiting
• Conditions: Physical Disability
• Intervention / Treatment: Behavioral: Virtually supervised exercise; Behavioral: Health education

Detailed Description

This study is examining if a virtually supervised exercise program can improve physical function in persons awaiting kidney transplant. A double-blind, parallel group randomized controlled clinical trial, this study will enroll 80 persons for 24 weeks. Our primary outcome is performance on the 30 second sit to stand test, and our secondary outcomes are changes in the Fatigue Severity Scale and the Beck Depression Inventory.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Virtually supervised exercise; In the first half of the study (weeks 0 to 12), participants will receive a virtually supervised exercise program. In the second half of the study (weeks 13 to 24), participant will continue to receive the virtually supervised exercise program.	Behavioral: Virtually supervised exercise; Participants will participate twice weekly in an live exercise program that they will access through a computer connected to the Internet.
Active Comparator: Health education; In the first half of the study (weeks 0 to 12), participants will receive a health education program. In the second half of the study (weeks 13 to 24), participant will receive a the virtually supervised exercise program.	Behavioral: Virtually supervised exercise; Participants will participate twice weekly in an live exercise program that they will access through a computer connected to the Internet.; Behavioral: Health education; Participants will first participate in a once weekly live health education class that they will access through a computer connected to the Internet. During the second half of the study, participants will participate twice weekly in an live exercise program that they will access through a computer connected to the Internet.
