This issue of Canada DIRECTIONS highlights innovative products and research emerging in Canada that have the potential to influence the provision of CRT, whether through new approaches, technological advancements or product development.
This article is presented into two sections: Research and Product.
Research innovation in Canada
Finding all the research occurring related to Complex Rehab Technology in Canada is challenging as there isn’t a central repository describing all the current research initiatives, but that doesn’t mean that innovation isn’t happening. Research related to CRT in Canada is occurring in many areas, including smart wheelchair and assistive mobility research, seating and pressure injury prevention research, wheelchair skills training, and spinal cord injury and rehabilitation. While not a comprehensive list, below are several innovations that are being explored.
Smart wheelchair and assistive mobility research
Device choice impacts on autonomy (https://mech.ubc.ca/2022/11/28/caris-research-on-wheelchair-users-sense-of-autonomy-in-nov-issue-of-assistive-technology) Researchers focused on how wheelchair users’ sense of autonomy changes depending on the device and environment. The highest satisfaction with perceived autonomy occurred with manual wheelchair users who used a power add-on device as it provided the greatest flexibility between environments. Research continues on how certain features such as speed and maneuverability influence the personal autonomy of people who use a wheeled mobility assistive device in various contexts. (https://caris.mech.ubc.ca/research/research-areas/mobility-assistive-technologies/) This research will help inform prescription practices of CRT to ensure autonomy is maximized.
Performance of power-assisted wheelchairs (https://caris.mech.ubc.ca/research/research-areas/mobility-assistive-technologies/) Currently available push rim-activated power-assisted wheelchairs haven’t changed users’ life satisfaction regarding the need to coordinate pushes on each wheel, safety and controllability on declines, difficulty of stopping and changing directions, battery life, chair weight, and assembly and disassembly. Research in this area is two-pronged: 1) developing control algorithms to improve the ease of coordination and use of push rim-activated power-assisted wheelchairs and 2) taking a modular approach to the push rim-activated power-assisted wheelchairs so that they can be configured for the individual. This research has the potential to change the types and configurations of power add-ons and the usability of these for our clients.
Brain-computer interfaces for wheelchair control (https://nserc-crsng.canada.ca/en/awards-database/773444 and https://www.ctvnews.ca/montreal/article/meet-milo-a-mind-controlled-mcgill-created-automated-wheelchair/ ) As the name suggests, this project is aimed at harnessing the user’s thoughts to translate them into the input to drive the power wheelchair. Currently experimental in virtual reality, users can control their movement using their thoughts. The aim is to create a new type of specialty control that could be prescribed for power wheelchair users that would enable them to control their wheelchair with their thoughts.
The Wheelchair Skills Program (https://wheelchairskillsprogram.ca/en/ ) is a set of free online low-tech, high-impact, evidence-based resources for the assessment and training of users’ manual and powered wheelchairs and motorized mobility scooters (with or without the assistance of caregivers). The program is a collection of wheelchair users, clinicians, educators and researchers with interest in and expertise related to the assessment and training of wheelchair skills.
The program is based in Halifax, Nova Scotia, with members contributing from multiple continents. Their research (https://wheelchairskillsprogram.ca/en/publications-impact/) spans many areas of wheelchair skills testing and training including design, training and provision of wheelchairs in varied geographical and living environments.
Currently there are ongoing studies investigating wheelchair service providers perspectives on a rear anti-tip device in enhancing participation without compromising safety. The device self-deploys through an arc when needed. It is designed for use with rigid or folding manual wheelchairs and is intended to improve skill and access level by assisting in skills such as weight shifting in an aided-wheelie and increasing abilities to overcome curbs and inclines as well as avoiding the issue of conventional rear anti-tips interfering with care providers feet and increasing the rear length of the wheelchair.
Research and development also continue with the training program. In addition to the free manuals, videos and other resources (please review conditions of use) supplemental supports are being researched and developed to target specific groups such as caregivers, users of languages other than English (https://wheelchairskillsprogram.ca/en/related-sites/#lang ) and pediatric wheelchair users (https://wheelchairskillsprogram.ca/en/pediatric/ ). Â Specific propulsion patterns of manual wheelchairs are also being studied. These self-directed online courses were designed to complement the existing resources by providing structured tutorials to help manual wheelchair users develop practical skills for everyday life.

Spinal cord injury and rehabilitation
MindMoveTM(https://myndtec.com/myndmove/) has been designed to help regain hand and arm movement and function for clients who have paralysis from a stroke or spinal cord injury. It is non-invasive and uses electrical signals to stimulate the brain to form new neural connections. This may have implications for individuals who need power mobility, and may be able to access a joystick rather than using specialty controls
Other research
Canadian Foundation for Innovation: Improving access to rehabilitation services for people living with complex rehabilitation needs using high-quality telerehabilitation services. (https://www.reachablerehab.com/rehabilitation-and-technology) The vast distances in Canada creates a geographic barrier to health equity. An individual with complex rehabilitation needs has a different ability to access care, including the prescription of a mobility device, depending on their geographical location in Canda. One way to improve equity is to provide telerehabilitation programs. This research, while focused on individuals with traumatic brain injuries, cerebral palsy or stroke, has implications for clients who require CRT and may help to inform telerehabilitation practices for the provision of CRT in remote areas. Virtual assessment will never replace the need for a hands-on postural assessment by a clinician, but it may help improve the efficiency of the assessment process and focus the hands-on components.
Fabric-Based Research Platform (FIBRE) (https://kite-uhn.com/fibre)  is a group of researchers investigating using textile-based HealthTech with a view to create “human-centered design and accessibility solutions.” Artificial Intelligence is used to interpret the data collected through the fabric to make recommendations. (https://myant.ca/) This has the potential to provide new approaches to CRT.
Imagine a world where clothing could deliver electrical stimulation to improve postural control, a textile that promotes wound healing or a garment/seat cushion cover that could detect the early signs of skin damage, especially for those with darkly pigmented skin for whom early detection of pressure injuries is often missed. Â This information could be sent to the individual and/or their care team to prompt proactive interventions.
Another example is SkiinTM Osmotex. (https://www.myantx.com/osmotex/)  This material is “self-drying” not just wicking moisture away but actively transporting moisture away from the body.
Product innovation in Canada
The ASL 504 Remote Stop Switch for R-Net is a safety device allowing caregivers to stop a power wheelchair within a 20-foot range. It uses a single switch to instantly halt the chair, aiding in training or for users with limited motor control. This product (https://www.asl-inc.com/products/product_detail.php?prod=48) is often used in crowded environments or for safety with individuals who have severe seizure disorders, providing an immediate remote stop system.
How it Works: Users can say “Hello Sunrise” to activate, followed by commands like “Sunrise 1” through “Sunrise 10” to tilt, recline, or elevate the legs.
Most suppliers have struggled to provide independence to the client who can activate a switch or their joystick when in an upright position, but once they are tilted, they lose the ability to access the switch and then lose the ability of reposition themselves. “Hello Sunrise” is the first voice activated system that would allow a client to control their power seat functions with simply their voice. There is some training and set up required, but this technology has the potential to allow clients more independence, even as they are losing motor control of their body.
Hello Sunrise
LUCI ( https://luci.com) is a currently available, smart technology for power wheelchairs. LUCI is a collision avoidance and obstacle avoidance system. The LUCI system actively senses and avoids obstacles when the client is driving the chair.
The client still drives their power wheelchair and has autonomy as they drive; however, the LUCI system will slow down the chair and avoid obstacles in the user’s path. The intent of this technology is to preserve the client’s driving independence while improving the client’s safety. It is an exciting technology as it offers the opportunity for independence for clients who may have difficulty steering around obstacles and may have been denied power mobility in the past.
LUCI
Braze Mobility (https://brazemobility.com) is a set of blind spot sensors that can attach to many different wheelchairs. These blind spot sensors provide feedback to the client to help them detect obstacles that may be in their way and then allows the user to navigate around those obstacles. Unlike the LUCI system it does not have an obstacle avoidance system that controls the wheelchair, avoiding the obstacle is totally in the hands of the client. This technology may be helpful for a client who has good motor control to drive their chair but does not have the mobility to look behind them or who may have low vision.
Braze Mobility
WHILL autonomous powerchairs (https://whill.inc.us/) are available at several major airports globally (such as Canada’s Winnipeg Richardson International, Los Angeles International and Miami International in the U.S., Japan’s Narita International and Amsterdam’s Airport Schiphol) to assist passengers with mobility issues in navigating terminals and reaching gates. Currently in Canada, WHILL autonomous (self-driving) powerchairs are available as a full-time service for passengers at Winnipeg to navigate between check-in and departure gates.
These self-driving units allow users to enter their gate number, and the chair drives them autonomously, returning to a docking station when finished. This innovation will enhance the independence of these travelers with reduced mobility and make traveling as easy as possible for them.
WHILL autonomous powerchairs
Three innovative products are described above to help draw attention to innovations we can access in Canada. The products featured, doesn’t necessarily denote a recommendation, but do illustrate that innovation is happening in Canada.
Although this amazing technology is available, lack of awareness by suppliers may make this technology unavailable to our clients.
Dissemination of this innovative research and products is challenging. Perhaps there is an opportunity for iNRRTS to collaborate and provide input, so we can bring these opportunities to the CRT community.
