Pain Studies Lab’s Research at PAINWeek 2019

By | Conferences, Events, Publications

On Sept 2-7, 2019, members of the Pain Studies Lab presented 5 posters at PAINWeek 2019, Las Vegas. PAINWeek is a multidisciplinary conference for frontline clinicians focusing on pain management.

PhD student Bhairavi Warke discusses results of the Pain Studies Lab’s research to a PAINWeek 2019 attendee.

Each poster articulates the results of our scientific and clinical studies. Many of these studies are with our long-time collaborators at the Arthritis Research Centre of Canada (ARC) and the BC Support Unit, and use cutting-edge design know-how and interactive and/or immersive technology newly built for helping patients with chronic conditions. The research studies that each poster describes is affiliated with a Pain Studies Lab project:

As-If 

The aim of this Virtual Reality (VR) platform is to raise empathy of aging people who live with chronic pain. In this VR game, a player “inhabits” a full-size 3D character or “avatar,” a grandmother who is struggling to accomplish everyday tasks. Players must strive to accomplish these tasks “as” this character. As they do so, their physical range of motion is restricted as their arm and wrist joints become red, and they hear the aging grandmother’s inner self-talk.

Players in the VR game As If “inhabit” the avatar of an aging chronic pain patient. From this first-person perspective, they try to perform everyday tasks as if they were that patient. The goal is to motivate empathy for chronic pain patients. After much testing, the initial version evolved into the VR version.

LumaPath

This VR game is intended to promote Range of Motion (RoM) exercises for aging chronic pain patients with Rheumatoid Arthritis (RA) or Osteoarthritis (OA). In a pilot study, patients were unaware that the range of motion gameplay in LumaPath conferred about 30% aerobic benefit. The older the patient, the higher the aerobic benefit.

Initially, the designers weren’t sure why aging adults were so enthusiastic about this steampunk-styled VR game until patients remarked that LumaPath’s ship bears a strong resemblance to the Beatles’ Yellow Submarine of their youth.

The Burden of Pain Symptoms

In a collaborative project, researchers from ARC, the BioV Lab and the Pain Studies Lab explored what “Citizen Science” might mean in health domains. Instead of asking people to count birds or measure water levels, the researchers considered engaging ways that citizens of British Columbia in Canada might share their pain symptoms, and how they would ensure that such data was anonymized and kept private and secure. Next, they partnered with Tactica Interactive to design and build a public health data-hub. The protoype web portal was tested “in the wild,” and is scheduled to launch in spring 2020.

Bhairavi Warke discusses an innovative new ‘citizen science’ project with an attendee at PAINWeek 2019 in Las Vegas.

The Virtual Meditative Walk

This immersive VR system incorporates bio-sensors and its Vocal Coach teaches chronic pain patients to learn Mindfulness-based Stress Reduction (MBSR), a well-validated method that has long been used to help chronic pain patients manage their long-term pain. The benefit of this VR system is the biosensors provide real-time feedback so patients know if their efforts are indeed having observable effects on their mind and body. Pain Studies Lab researchers are now looking at its potential long-term neurological benefits.

In the Virtual Meditative Walk, as patients reduce their stress levels by focusing on their inner states — like their heartrate and breathing — they see and hear changes in the “weather”: fog and clouds gradually disappear, and birds and insects become more active in the virtual forest.

FitViz

In collaboration with ARC, researchers from SFU’s BioV Lab created and clinically tested FitViz, an app that uses a FitbitTM to help patients with Rheumatoid Arthritis (RA) and Osteoarthritis (OA) and physiotherapists to track & monitor their physical activity levels.

FitViz also determines and recommends the frequency and exercise level for individual patients, termed “bouts.” In this way, patients can get a sense of how much exercise is best for their specific needs and can monitor their own progress, while their physiotherapists can follow and adjust their recommendations.

The Pain Studies Lab’s researchers also presented results of VR studies that lab member Xin Tong conducted over several months in Beijing:

  • A study among participants in Beijing exploring body ownership, sense of agency and heat pain perception using VR and Leap MotionTM sensors.

Redefining ‘Citizen Science’: Pain Studies Lab with the Arthritis Research Centre

By | Workshops, Collaborations, Events

An innovative workshop redefines what ‘Citizen Science’ can mean in health domains

On April 18th, 2019, Dr. Diane Gromala, Dr. Chris Shaw, Ankit Gupta, Bhairavi Warke and Sherry Wang from SFU’s Pain Studies Lab led a co-creation workshop with their long-time collaborators from the Arthritis Research Center: Dr. Linda Li, Hussein Mamdani and Juliane Chien at University of British Columbia in Vancouver. In this innovative workshop, health researchers and their patient-partners got together to explore new approaches to collecting information about ‘the burden of symptoms’ from patients in British Columbia (BC), Canada.

Participants shared their experiences of trying to define and articulate their ‘burden of pain’ symptoms on their biopsychosocial realities, as well as their abilities to function and their quality of life.

The objective: to question what ‘Citizen Science’ might mean in health domains. Instead of asking citizens to count birds or measure water levels, we plan to ask citizens of BC about their pain symptoms — whether or not they have been diagnosed with a particular condition(s). For health research, this may prove to be an innovation since research often follows a diagnosis, and is usually categorized according to a diagnosis or disease.

The workshop was derived from ‘design thinking’ approaches. It structured the way we explored different methods for collecting the pain-related data, including: a standard medical classification list of symptoms, the well-known McGill Pain Questionnaire, information from questionnaires about function and quality of life, ‘Mood Cards’ and lots of post-it notes, tags and writing implements.

In addition to ARC’s patients-partners, the health researchers participating in the workshop played the role of citizens who would be contributing information about their health anonymously. By doing so, we all got a deeper understanding of how rich pain-related data could be, and how complex it is to communicate.

The workshop comprised four phases:

  1. choosing medically classified symptoms,
  2. annotating a human figure with those symptoms,
  3. describing how their symptoms impacted work, family, life and social contexts, and
  4. choosing “mood cards” to help articulate psychological contexts.

Outcomes of the research revealed a high level of complexity required for such a system and helped identify the needs not only of the citizens who would be contributing their information but also the health researchers who would use that information. The teams plan to further refine their approach and test for security, privacy, usability, compliance, and effectiveness.

Pain Studies Lab @ Virtual Medicine 2019 — Cedar-Sinai Medical Center

By | Demos, Conferences, Projects

Dr. Diane Gromala was invited to give a talk at Virtual Medicine 2019, a medicine and immersive virtual reality (VR) conference at Cedars-Sinai Medical Center in Los Angeles.

In her talk, “How VR Cures by Enabling Self-Awareness,” Dr. Gromala discussed her approach to developing, testing and deploying VR technology for chronic pain patients. A pioneer in Virtual Reality (VR) for long-term pain, Dr. Gromala’s approach is the result of technological innovation, user-centered design, and scientific evidence-based research she has conducted with thousands of patients since 1991.

Members of the Pain Studies Lab — Dr. Chris Shaw, Bhairavi Warke (Ph.D. student) and Ruoyu Li (M.Sc. student) — also participated in the conference. They demonstrated LumaPath, one of the lab’s scientifically-validated immersive VR systems for reducing chronic pain through exercise. The team both develops the VR technology and designs the ‘content’ of what patients see, hear and interact with.

Currently, the team is investigating the longitudinal effects of VR used at home by chronic pain patients. As VR has been termed a non-pharmacological “analgesic,” the team is also investigating what the best “VR dosage” is — that is, what the best duration in VR is for the ideal analgesic effect.

The main objective behind the Citizen Science workshop was to test different methods for collecting data on symptoms from people who may — or may not — have been diagnosed with a particular condition. The health researchers participating in this workshop were also patients themselves, and played the role of citizens who would be contributing information about their health anonymously.

The outcomes of the research revealed a high level of complexity required for a system and helped identify the needs not only of the citizens who would be contributing their information, but also of health researchers who would use that information. The team’s next step is to further refine their approach and test it for security, privacy, usability, adherence and effectiveness.

Pain Studies Lab presents AI research at IEEE GEM 2018

By | Conference Papers, Conferences, Papers, Publications

Weina Jin, a Pain Studies Lab Ph.D. student, presented her research on using machine learning to predict cybersickness at the IEEE GEM 2018 conference in Galway, Ireland on August 17, 2019.

In her 20-minute talk, Weina outlined the challenges of building predictive models for cybersickness research. To address these problems, she and her colleagues used a pure data-driven approach. They constructed a dataset for this problem, collected VR gameplay data labeled with a cybersickness core and built machine learning models. In their pilot study, results showed that their machine learning could model cybersickness in real-world VR gameplay settings. The presentation was part of Session 3.4: Deep Learning Techniques for GEM.

Their full peer-reviewed paper will appear in the IEEE GEM’s Conference Proceedings: “Automatic Prediction of Cybersickness for Virtual Reality Games” by Weina Jin, Jianyu Fan, Diane Gromala and Philippe Pasquier.

The IEEE GEM (Game, Entertainment, and Media) 2018 conference is a platform for disseminating innovative research and development work on game, entertainment, and media technologies.

Pain Studies Lab Ph.D. student Xin Tong is collaborating with a prominent pain doctor & motor control expert at Peking U. in Beijing

By | Collaborations, Lab Updates

Xin Tong, one of the lab’s Ph.D. students, is conducting her dissertation research in Peking University’s Motor Control Lab with Dr. Kunlin Wei, one of the top brain and cognition scientists in China.

Xin’s research is mainly about

  1. identifying the major factors in Virtual Reality (VR) that affect pain perception, and
  2. how to use Virtual Reality to help chronic pain patients to better manage their pain.

Her studies focus on the sense of body ownership, the sense of body agency, and the senses of controllability, movement and physical activity in VR, and how they may influence pain perception in both healthy participants as well as pain patients. Eventually, she plans to apply those research findings and scientific results to the lab’s VR.

Currently, Xin is working with pain patients who live with Complex Regional Pain Syndrome (CRPS), as shown in the picture below. This patient has experienced CRPS-related pain for over four years in his feet and hands. Before using the VR environment, the patient he rated his pain level as a 10 — almost always, and almost everywhere in his hands and feet. After engaging with the Pain Studies Lab’s VR title LumaPath for around 20 minutes, the patient rated his pain level to be 8, which lasts for a short period.

Although this result occurred after only one “dose” of VR, the result was significant, particularly because this patient’s pain is unrelenting. Therefore, over the next 8 to 10 weeks, Xin will follow up with a group of pain patients to measure the effects of using VR over time, and to see if those effects persist.
