The aim of this study was to investigate research trends in sandplay therapy in South Korea. Thus we analyzed 205 Korean research papers published between 2009 and 2018. We grouped our results into five categories using the research trend analysis method. Those categories were research topic, subject, method, and characteristics of sandplay therapy. The results reveal the current status and limitations of sandplay research. These also suggest future research directions for sandplay therapists and researchers.

Poverty has forced over a million children in Uganda to live on the streets. These children often come from families where they suffered violence and sexual abuse. Besides starvation and unhygienic conditions, street children face physical and sexual abuse. The perpetrators range from adults such as the police to other street children. For our study, we recruited sixteen former street children, eight boys and eight girls. They were living in a child welfare facility at the time of research. We used the mixed research method for our research design. For quantitative research, we used two measures: CRIES-13 (Children's Revised Impact of Event Scale-13), CYRM-28 (Child & Youth Resilience Measure). We used a qualitative case research method to analyze the themes in the sandplay process. The quantitative results indicated that the group sandplay therapy improved PTSD Symptoms and resilience. The qualitative results revealed several common themes such garbage, salvation and big project.

This study investigated inter-right brain synchrony between therapist and client in Sandplay therapy, using hyperscanning technique based on functional near-infrared spectroscopy (fNIRS). fNIRS is a non-intrusive method that measures changes in oxyhemoglobin the cerebral blood. A total of seven therapist-client pairs-i.e., 14 participants-wore fNIRS devices on their heads and engaged in two sessions of Sandplay therapy, with each session lasting for 30 minutes. The study observed synchronization in the right and left prefrontal cortices of both therapists and clients in all seven pairs, during every session. Interestingly enough, synchronization occurred not only while the pairs engaged in verbal communication about the completed sandpicture but also during the non-verbal process of clients' creating sandpictures. The outcome of the study hence suggests neurobiological fundamentals for the therapeutic relationship between therapist and client, which is also called the therapeutic resonance, relational mutual regression, therapeutic alliance, and mother-child unity.
