Ngulluk Moort, Ngulluk Boodja, Ngulluk Wirin (our family, our country, our spirit): An Aboriginal Participatory Action Research study protocol.

Globally, Indigenous children have historical and contemporary connections with government child protection services that have caused significant harm to their long-term health and wellbeing. Innovative, culturally secure and recovery focussed service provision is required. This paper describes a research protocol that has been designed by Indigenous researchers led by Indigenous Elders, to explore culturally secure care planning and service delivery in out-of-home care agencies in Australia. Using participatory action research methods, we will collect data using a variety of forums, including focus groups and semi-structured interviews. These data will explore the challenges for out-of-home care agencies in providing culturally secure care-planning, cultural activity and resources, and explore solutions to address factors that influence health and can assist to redress social inequities for Indigenous children. We aim to recruit approximately 100 participants for the qualitative study and 40 participants for the quantitative survey. Study participants will initially be recruited using purposive sampling, and as the study progresses will be recruited using a mixture of purposive and convenience sampling techniques. The rich data that this study is expected to yield, will inform ways to collect cultural information about Indigenous children and ways to provide cultural connections and activities that will have benefit to Indigenous children and families, and a broad range of social services.

Anodal Transcranial Direct Current Stimulation Reduces Secondary Hyperalgesia Induced by low Frequency Electrical Stimulation in Healthy Volunteers.

The aim of the study was to determine whether transcranial direct current stimulation (tDCS) reduced pain and signs of central sensitization induced by low frequency electrical stimulation in healthy volunteers. Thirty-nine participants received tDCS stimulation under 4 different conditions: anodal tDCS of the primary motor cortex (M1), anodal tDCS of the dorsolateral prefrontal cortex (DLPFC), anodal tDCS over M1 and DLPFC concurrently, and sham tDCS. Participants were blind to the tDCS condition. The order of the conditions was randomized among participants. Pain ratings to pinpricks, the current level that evoked moderate pain, and pain induced by low frequency electrical stimulation were assessed in the forearm by an experimenter who was blind to the tDCS conditions. Anodal tDCS at M1 increased the current level that evoked moderate pain compared to sham and other conditions. Anodal tDCS of DLPFC completely abolished secondary hyperalgesia. Unexpectedly, however, concurrent anodal tDCS over M1 and DLPFC did not reduce pain or hyperalgesia more than M1 alone or DLPFC alone. Overall, these findings suggest that anodal tDCS over M1 suppresses pain, and that anodal tDCS over DLPFC modulates secondary hyperalgesia (a sign of central sensitization) in healthy participants. PERSPECTIVE: Anodal transcranial current stimulation (atDCS) at the left motor cortex and the dorsolateral prefrontal cortex increased the electrically-evoked pain threshold and reduced secondary hyperalgesia in healthy participants. Replication of this study in chronic pain populations may open more avenues for chronic pain treatment.

Delivering Elder- and Community-Led Aboriginal Early Childhood Development Research: Lessons from the Ngulluk Koolunga Ngulluk Koort Project.

Elder- and community-led research processes are increasingly being acknowledged as critical for successful Aboriginal health and wellbeing research. This article provides an overview of the methodologies, methods and progress of the Ngulluk Koolunga Ngulluk Koort (Our Children, Our Heart) project-an Elder- and community-led research and research-translation project focused on the early childhood development of Australian Aboriginal children in an urban context (Perth, Western Australia). We describe the application of a participatory action research methodology that is grounded in Aboriginal worldview(s), from the collaborative development of the original idea to the post-funding processes of co-design and implementation, data collection, analysis, interpretation and translation.
