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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

ACTRN12621000139875 is the main trial of which the current application is a sub-study.
Participants enrolled in ACTRN12621000139875 will be offered the option to participate in this substudy, which involves an extra testing session before after the intervention period, in which they will have MRI scans.

Study type
Interventional
Description of intervention(s) / exposure
ACTRN12621000139875 describes a 12 week intervention using a physical exercise assistance device for patients with Parkinson's disease. The primary outcome measure was part 3 of the UPDRS ratings scale. The current application will include new patients enrolling in that trial and add MRI scanning as an additional outcome measure. After approval of this registration, all patients recruited in the main trial will be offered the option to undergo MRI scanning, which will involve T1, T2, diffusion and functional MRI scans at baseline and follow up, in addition to the other outcome measurements for the main trial described in step 4.
Imaging sessions will take place the week prior to the intervention commencement and 13 weeks after intervention commencement. They will last 30 minutes. The will be conducted by a radiologist at Alfred Hospital.

Summary
Brief summary
This sub-study will test the effect of a novel therapeutic exercise machine on MRI-derived measures of brain health in patients with Parkinson's Disease and Atypical Parkinsonism.
The Reviver exercise machine simultaneously stimulates the vestibular system whilst inducing isometric exercise.
We hypothesise that a 12 week intervention on the Reviver will increase brain volumes, decrease number of enlarged perivascular spaces and decrease brain iron deposition.
