; ; ; ; ; ; ; ; ; ;

Dr. Miller works on wheelchair mobility issues, wheeled mobility devices, determinants of wheelchair use, developing and evaluating measurement tools, balance and ambulation confidence, and the assessment of technology used to assist with mobility. He also researches the social impacts of wheelchair use. The goal of improving mobility for wheelchair users is to help them integrate back into society more easily and effectively. Dr. Miller’s childhood was spent with a father who was in a wheelchair following military service, and thus, for Dr. Miller wheelchairs were a part of regular life. It wasn’t until he headed out on his own that he realized that life was different for many, and he decided then to help improve life for all wheelchair users.Em

Dr. Miller is a Professor in the Department of Occupational Science and Occupational Therapy at the University of British Columbia. He also holds a joint appointment with the UBC School of Rehabilitation Sciences and is a Principal Investigator at ICORD. He pursued his B.Sc. in occupational therapy at the University of British Columbia, followed by an M.Sc. and a Ph.D. at the University of Western Ontario and a Post-Doctoral Fellowship back at the University of British Columbia.

For Dr. Miller, the interdisciplinary nature of ICORD is its main strength. It grants researchers the ability to see something from an entirely different perspective, using different lenses to view the world and the research related to SCI.

Currently recruiting for:

Exploring empathy amongst individuals with SCI or TBI

The purpose of this study is to explore the role of empathy in the daily lives of individuals who have an acquired spinal cord injury (SCI) and/or traumatic brain injury (TBI). Individuals will participate in a phone or Zoom interview Read More...

Peer-led eHealth wheelchair skills training program: TEAM Wheels

Evaluation of a peer-led eHealth wheelchair skills training program: TEAM Wheels This research study is being conducted to evaluate the effect of a peer-led eHealth manual wheelchair (MWC) training program (called “TEAM Wheels”) among individuals transitioning to MWC use. The Read More...

Recent Collaborations:

The Canwheel team encompasses six institutions from across Canada with fourteen investigators (including ICORD researcher Dr. Bonnie Sawatzky) from a wide variety of fields, including Psychiatry, Occupational Therapy, Engineering, Gerontology, and Sociology. There are five main projects designed to provide a comprehensive, systematic, and unified approach to enhancing the mobility of older adult wheelchair users.

Dr. Miller is a member of F2N2, otherwise known as Fatigue and Function of Neuromuscular and Neurological conditions. This team of local investigators, which includes ICORD clinical scientists Drs. Hugh Anton, Sue Forwell, and Andrea Townson, is attempting to address the debilitating effects of fatigue by developing improved measures and strategies to cope with this secondary health condition.

Dr. Miller is co-investigating a number assistive technology development projects with ICORD scholar Dr. Jaimie Borisoff. Together they are examining clinical and consumer views of a novel accessibility design (e.g. outside stair lift) as well as the utility of the elevation wheelchair.

Major Findings:

Dr. Miller’s work has developed to remedy what he sees as a real gap in rehabilitation: the role of self-efficacy in mobility issues arising during rehabilitation. Many rehabilitation professionals focus on skills but not on confidence. Dr. Miller’s work suggests that confidence is perhaps even more important, as it provides greater motivation than the development of specific skills. Dr. Miller was among the first to publish in this area for key rehabilitation populations (e.g. lower limb amputation, stroke and spinal cord injury) in areas related to falling, ambulation and wheelchair use. Members of his lab are currently developing interventions to promote confidence which will hopefully lead to increased participation in social activities.

Dr. Miller research program also features the development and evaluation of clinical outcome measures. The focus of his work to date relates to measures of wheelchair seating and mobility as well as tools designed to capture information on confidence with ambulation and wheelchair use.
