Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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
Low-frequency repetitive transcranial magnetic stimulation (rTMS). rTMS is a non-invasive procedure that involves the administration of magnetic pulses to the scalp, which are able to stimulate the underlying brain tissue (i.e., cause brain cells to become active). rTMS can be used to either increase or decrease activity in a certain part of the brain.
The application of TMS involves 15 minutes of 1 Hz rTMS (i.e., 1 pulse per second for 15 minutes) to (a) primary motor cortex and (b) supplementary motor area. These are done in separate sessions. All participants will receive both arms, plus the control treatment (Sham rTMS). The order of the three conditions (i.e., rTMS to primary motor cortex, rTMS to supplementary motor area, Sham rTMS) will be randomised. There is one week between each of the three conditions.
Intervention code [1] 241500 0
Treatment: Devices
Comparator / control treatment
Sham repetitive transcranial magnetic stimulation. This involves the administration of rTMS as described in the intervention, but the TMS coil is angled away from the scalp; thus, no magnetic pulses are delivered to the brain.
Control group
Placebo
