Liminal VR

One of the hallmarks of the Liminal Platform is our psychometrics - which are standardized scales designed to obtain self-report data about a user's emotional or cognitive state. To date, across the entire Liminal Platform, we have achieved over 1.6 million psychometric data points and 500,000 five-star enjoyability ratings.A range of other clinical/academic evaluations (completed or ongoing) have yielded positive results, including:

1. Post Operative Surgery* (Monash University Clinical Trial - see above) - patients after laparoscopic surgery reported less pain than a control group receiving post-operative care after using one of Liminal's pain relief experiences (Meridian). Monash has reported a trend towards lower heart rate and less opioid usage. 90% patients reported that they would use VR again post-surgery and would recommend it to others.
2. Intraoperative Surgery (Georgetown University and Northeastern University) - Researchers (also using Meridian) saw reported reduction in pain while receiving lumbar epidural steroid injections. 75% of participants said they would prefer to use VR in future procedures.
3. RMIT University Sleep Study* - one of Liminal's sleep experiences (Waves of Tranquility) has seen participants fall asleep on average 11.74 minutes earlier than when reading alone.
4. Pain Matrix Clinical Outpatient Pilot - Dr Jacquelyn Nash, a pain management specialist, piloted one of Liminal's pain relief experiences (Cosmic Conductor) among 28 chronic pain sufferers, who reported a 26% reduction in pain, a 39% reduction in anxiety and average enjoyment rating of 8.8 out of 10.

Over the past 6 years, Liminal have partnered with Wellbeing in Schools Australia (WISA), an Australian focused not-for-profit with whom we have piloted two large scale rollouts of the Liminal Platform in over 40 Australian schools.

Evaluation results have seen students, staff and school counselors/psychologists report positive effects on their mental health and wellbeing. Schools have reported that the Liminal Platform is a valuable promotion, prevention, and early intervention tool to help students improve their mood, reduce anxiety and cope with stress.

They have also reported the Liminal Platform helping vulnerable, disengaged and disruptive students stay in class and build their resilience.

Evaluation results from the most recent pilot (funded by the Australian Government Department of Education across 32 schools) has found that:

• 91% of students reported a positive impact on their mental health and that the Liminal Platform
• 75% of students reported reduced stress and anxiety.
• 100% of school counselors reported it improved students mood and wanted to keep using it.
• 86% of teachers stated it had an extremely positive impact on their own mental health.

Serco Asia-Pacific piloted Liminal experiences in a range of call centers who have found that poor customer behavior represents significant psychological risk for their staff. Staff were encouraged to use Liminal experiences each time they experienced distressing calls.

In an internal publication, they reported the results as follows:"Over four weeks, the teams participated in over 100 VR sessions, capturing complex psychometric data and feedback. The results were overwhelmingly positive. We found an overall 42% increase in positive emotions and 30% reduction in negative emotions following the use of the headset.

Following the initial trial, we have been introducing the VR headsets to other contact center sites, which has been welcomed by our frontline teams. At one site, for example, use of the VR headset has been integrated into the daily schedule for Complaint Handling Team Members."According to Anthony Bourke, Performance Optimisation Lead, Serco Citizen Services:"For agents who have a challenging or distressing call, we have found it provides a great mental 'reset' that allows them to continue with their work day, where before they may have had to go home for the day or taken a negative mindset into the next call."The pilot was awarded a Global Serco Pulse award in the innovation category and resulted in significant uptake within a range of operational areas within Serco.

A recent feasibility study conducted by Royal Prince Alfred Hospital (Department of Anaesthetics and Pain Management Centre) was conducted into the use of the Liminal Platform among patients who had been hospitalized with chronic pain.

Across 486 user sessions, the pilot found demonstrable improvements in mood and anxiety and a reduction in reported levels of pain.

Pre- and post-psychometric testing found a 29.7% increase in patients reporting calm or relaxed after using experiences in the Calm experiences, a 16% increase in patients reporting being cheerful or excited after using Energy experiences, and a 11.7% reduction in reported pain.

Clinicians within the hospital reported that the headsets were very popular among patients and in high demand. Due to the success of the feasibility study, the hospital has since expanded on the pilot and the clinic is adapting the program into clinical use.

Patient feedback included:

• "I have been using it as my sleeping tool. I have tries to stop using it for a week and found it is hard to sleep"- Female patient (de-identified), 53 years old.
• "I slept through most of the night since using it, it's changed, before almost every night I would wake up in midnight in pain...I don't really need to take another pain killer [after this], I just do some breathing exercises again, and it makes me more cheerful."- Male patient (de-identified), 61 years old.
