Research Interests
Arthrogryposis; assistive devices; Biomechanics; Energy expenditure; Long term outcomes; Mobility; spinal cord injury; Wheelchair propulsionDr. Sawatzky’s main research focus is mobility and quality of life for people with SCI and related spinal cord diseases (SCI/D). Specifically, she has done considerable research on wheelchair propulsion in both powered and manual wheelchairs, looking at how to improve efficiency of the manual wheelchair (caster sizes) as well as innovative assistive devices such as the SmartDrive or Rowheels which were designed to enhance wheeled mobility. In addition to assistive devices, she is also part of a team with Dr. Ben Mortenson, Dr. Patricia Mills, and Dr. Kathleen Martin Ginnis creating a mobile app to help people with SCI manage the complications associated with having an SCI.
Testing Modified Rowing Ergometer (aROW)
Dr. Sawatzky is also interested in assistive devices that enable people with SCI and other disabilities to exercise. She is currently collaborating with ICORD PIs Dr. Jaimie Borisoff, Dr. Carolyn Sparrey, Dr. Andrea Bundon and Dr. Ben Mortenson and collaborator Dr. James Laskin on a modified rowing ergometer (aROW) and other ergometers to give people with SCI more options for exercise.
She is currently studying the long-term outcomes of those with a congenital spinal cord disorder called Amyoplasia (an anterior horn cell deficit), a sub-group of patients diagnosed with Arthrogryposis Multiplex Congenita (AMC). She has published the largest international adult outcome study of this population using the Rick Hansen’s Global Research Platform (RHI-GRP) through Praxis. She now manages the largest Adult AMC Registry funded by CIHR, ICORD and Praxis to study this rare population over time. She is a member of a North American Arthrogryposis Research Advisory Team and recently joined the global group in France called the International Collaboration on AMC which is working to create an integrated clinical and self-report database on children and hopefully adults with AMC
Dr. Sawatzky is an Associate Member at ICORD and an Associate Professor in the Department of Orthopaedics at UBC. She obtained her Ph.D. from Simon Fraser University. Because her work involves direct contact with people with SCI, Dr. Sawatzky is happy to have the access to these people that the ICORD environment provides. She enjoys the relationship between researchers and individuals with SCI/D. ICORD also hosts a collegial environment between the students, staff, and faculty, as well as up-to-date equipment.
She teaches in the Faculty of Medicine communication skills and professionalism, is currently a coach for medical students and supervises many medical students in research projects. She now has the role of UBC’s Department of Orthopaedics, Equity, Diversity and Inclusion lead.
Dr. Sawatzky and Gucci, September 2019
Currently recruiting for:
Dr. Bonnie Sawatzky carries the 2010 Paralympic Torch at UBC in February, 2010
Recent Collaborations:
She is also working with Dr. Rachael McDonald from Swinburne University in Australia to establish the Oceania Seating Symposium in New Zealand/Australia hundreds of therapists, clinicians and engineers every other year to Rotorua/Melbourne to learn about the latest developments in seating and mobility.
Major Findings:
Wheelchair caster size is an important component that should not be overlooked for deciding what to select when setting up a wheelchair. If a person tends to spend a lot of time outside or on carpet then a 5” and even better yet 6” casters significantly reduces rolling resistance. Larger casters are not ideal inside but one must weigh the costs and benefits.
The biomechanics of the Smartdrive (rear-mounted power assist on manual wheelchairs) showed that participants did not have to significantly increase their push force to start the drive. People could stop it quicker and with less force while using the Smartdrive. This device may be very helpful for people to use who have lessened strength due to overuse issues from wheeling.
People born with arthrogryposis (mainly Amyoplasia), despite their significant physical challenges with activities of daily living and mobility manage to become more educated than the non-disabled population, 50% get married and 75% manage to live independently or with a partner/roommate. They work most commonly in managerial or administrative jobs. They experience a significant amount of pain and require 5-10 surgical interventions to manage their limb/spinal deformities.
Techniques employed in the lab:
- Biomechanical measures such as the force-sensing SmartWheel
- Electromyography (EMG)
- Motion capture to gather kinematic data
- Physiological oxygen consumption to measure energy expenditure
- Segway
- Smartdrive
Affiliation with organizations and societies:
- Organizing Committee, Oceania Seating Symposium
