Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

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
Anodal and cathodal transcranial direct current stimulation (tDCS) of primary motor cortex using a saline-soaked pair of surface sponge electrodes at constant current intensity of 2 milliamps for 20 minutes administered daily during 2 x 5 day periods separated by 4 weeks without treatment. The site of electrode placement will be determined using a standard Electroencephalography (EEG) head cap used to position EEG recording electrodes. The anode electrode will be placed over C3 or C4 (using EEG 10/20 system) and the cathode electrode over the contralateral supraorbital area (i.e. above the opposite eye socket).

Magnetic resonance imaging (MRI) pre- and post-treatment to investigate brain alterations associated with reduction in pain intensity using tDCS. Functional MRI (fMRI) and structural imaging performed prior to and immediately following each treatment week and at 10 weeks and 6 months follow-up after study commencement.
Intervention code [1] 3911 0
Treatment: Devices
Comparator / control treatment
Control (sham) stimulation in which transcranial direct current stimulation will be delivered for 30 seconds using surface sponge electrodes placed in the same positions as for active stimulation and then discontinued for the remainder of the 20 minute treatment session. All subjects will receive both real and sham stimulation, each comprising 5 daily sessions with a "washout" period of 4 weeks between them (i.e. all subjects will receive the active treatment in one 5 day treatment period and the placebo treatment in the other 5 day treatment period).

Placebo
