1. Chee, Justin. Foot Placement Patterns of Individuals with Multiple Sclerosis during Rollator-assisted Community Mobility.

Degree: 2011, University of Toronto

Individuals with Multiple Sclerosis commonly use assistive mobility devices, such as rollators, to compensate for their mobility impairments. However, the effect of these devices on their foot placement during gait has not been explored in the community. The objective of experiment one was to develop and validate a tool that quantifies medio-lateral foot placement characteristics during rollator use. In this study, a technique was developed for an instrumented rollator (i.e. iWalker) and validated against a Vicon motion capture system in able-bodied young adults. The two systems were in strong agreement. The objective of experiment two was to apply this iWalker-based technique to individuals with Multiple Sclerosis to identify environment-related foot placement changes. This study revealed that step width variability, but not step width, can be influenced by certain outdoor environments. Therefore, environmental context is important to consider when investigating user-device interactions and factors responsible for safe mobility in this population.

2. Ellis, Denine. Investigating the Relationship between Stride Interval Dynamics, the Energy Cost of Walking and Physical Activity Levels in a Pediatric Population.

Degree: 2010, University of Toronto

The strength of time-dependent correlations known as stride interval (SI) dynamics have been proposed as an indicator of neurologically healthy gait. Most recently, it has been hypothesized that these dynamics may be necessary for gait efficiency although the supporting evidence to date is limited. To gain a better understanding of this relationship, this study investigated stride interval dynamics, the energy cost of walking, and physical activity in a pediatric population. The findings indicate that differences in energy cost are not reflected in the stride interval dynamics of able-bodied children. Interestingly, increasing physical activity levels were associated with decreasing variance in stride interval dynamics between subjects, though this finding only approached significance (p=0.054). Lastly, this study found that stride interval dynamics in children as young as nine years were comparable to stride interval dynamics found in healthy young adults.

3. Leung, Regina. Design of a Haptic Simulator for Pedicle Screw Insertion in Pediatric Scoliosis Surgery.

Degree: 2013, University of Toronto

The following work presents the design of a haptic training simulator for pedicle screw insertions in pediatric scoliosis surgery. In particular, the haptic simulator simulates the haptic sensations associated with probe channeling through the pedicle using the free-hand technique. The design includes 1 DOF custom haptic device, haptic model, and controller. The design is tested and evaluated for feasibility through a small pilot studying involving 5 expert surgeons. Significant agreement across expert surgeons was obtained regarding the feasibility and potential for the simulator to be a useful training tool.
