COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

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

Study type
Description of intervention(s) / exposure
Treatment: Devices - Spinal cord stimulation system

Experimental: Spinal cord stimulation -

Treatment: Devices: Spinal cord stimulation system
An implantable pulse generator (IPG) will deliver low-intensity electrical pulses which travel from the IPG through the leads to the electrodes positioned at the selected nerve fibers to provide the therapeutic stimulation.
