Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
8 weeks of gym-based exercise training, consisting of both cardiovascular and resistance training, 3 times a week for an hour each sessio. In addition, subjects will participate in a progressive walking program consisting of daily walking at a rate of perceived exertion of 13 on the Borg scale, increasing duration at this intensity. Initially patients may only be walking for 5 minutes, and this duration will be increased on an individul basis. subjects will complete the walking program for 8 weeks.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation sequence will be concealed using sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
subjects will be randomly assigned via a computerised algorithm to either the eight week mobilization program or the eight-week aerobic and strength training program in addition to the mobilization program.

Summary
Brief summary
The purpose of this study is to examine the effect of an eight week cardiovascular and strengthening exercise program on maximum exercise capacity (VO2 peak), quality of life scores and six minute walk distance in patients with a LVAD. The experimental hypothesis is that patients with a LVAD who participate in the eight week gym-based exercise program, in addition to a progressive walking program, will have significantly greater improvements in maximal and submaximal exercise capacity and quality of life compared to those that participate in a progressive walking program alone.
