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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Summary
Brief summary
The specific aim of this project is to improve walking ability in persons following stroke using 'treadmill training plus power training'. This modality addresses the two major impairments followings stroke: weakness and incoordination, as well as loss of fitness. Importantly, this training will be presented at higher intensity and greater volume than is currently received. Furthermore, to ensure that persons continue to maintain the level of improvement from an intensive exercise program, we will also implement a behavioral change for long-term maintenance of exercise behavior in a less supervised environment. A randomized controlled clinical trial will be conducted in 102 sub-acute stroke patients to ascertain the efficacy of this approach to improving walking ability.

Hypotheses:

1. Walking endurance will be increased to a greater degree in a patient group receiving treadmill plus muscle power training compared with a treadmill training only group, or 'usual care' group.
2. Gait stability, muscle function, aerobic fitness and balance will improve more in a group receiving treadmill plus muscle power training, than either those in treadmill training or usual care patient groups.
3. Habitual activity levels will be higher in the group receiving treadmill plus muscle power training compared with a treadmill training only group or 'usual care' group.
4. The change in 6-minute walk distance will be positively related to changes in muscle power, strength and endurance, aerobic fitness, gait mechanics, and balance.
5. Baseline depression and low self-efficacy will be associated with less robust adaptations to all types of training and lower rates of long-term compliance to the exercise prescription in the experimental groups.
