Study of Resistance Strengthening Versus Ambulation Post-Liver Transplant

October 6, 2010 updated by: University of Miami

Comparison of Targeted Lower Extremity Strengthening and Usual Care Progressive Ambulation in Subjects Post Liver Transplant: A Randomized Controlled Trial

Resistance strengthening exercise will increase strength and functional activity greater than ambulation in subjects post-liver transplantation.

Conditions

Intervention / Treatment

Detailed Description

Individuals post liver transplantation are significantly muscle wasted due to chronic liver disease. Current Usual care only involves progressive ambulation. Resistance exercise targeted at the lower extremities are anticipated to increase muscle strength in the muscles that extend the hip, extend the knee, and plantar flex the ankle more than seen with the usual care ambulation. The anticipated increases in strength should improve functional performance of activities such as standing from a chair, walking, and climbing stairs. The improvement in strength and functional performance should improve an individuals quality of life.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Resistance Strengthening
Body weight antigravity positioning and elastic resistance bands are used to provide resistance for strengthening in supine, sitting, and standing in subjects post liver transplant.
Other: Resistance Strengthening Exercise Program
Home exercise Program. 3-4 days a week. 30 minutes a session. 12 weeks
No Intervention: Usual Care Control
Subjects perform the usual care of progressive ambulation and increased activity post liver transplant
