Research Focus

The overarching focus of my research is investigating lower extremity biomechanics to develop and optimize injury prevention and gait retraining interventions that can prevent injuries and/or delay the onset and progression of orthopaedic diseases. The interdisciplinary research group develops pre-clinical and clinical research that produces research of consequence. Our state-of- the-art biomechanics laboratory instrumentation (e.g., motion capture, force plates, ultrasound imaging) enables best research practices for basic and translational research. We also conduct community outreach to provide evidence-based interventions to prevent falls in older adults.

Current Projects

■ Investigation of injury prevention feedback frequency to decrease anterior cruciate ligament injuries in active individuals: we are using motor learning paradigms of how frequently individuals should receive feedback to optimize learning and acquisition of motor skills.

■ Comparison of the effects of gait modification strategies on knee adduction moment in patients with medial knee osteoarthritis: randomized controlled trial: we are implementing an RCT using haptic feedback to assist individuals with knee osteoarthritis by improving gait mechanics and consequently decreasing cartilage degeneration and total knee replacements.

■ Evidence-based intervention to decrease falls risk on older adults: for the past 3 years, we have received funding for a community outreach program to deliver evidence-based interventions to community-dwelling older adults. The primary aim is to reduce the risk of falls and number of falls experienced by older adults, and improve quality of life and independent life.

■ Investigation of biomechanical patterns in dancers: a comparison study: this unique study uses a multiprong approach to investigate injury risk differences between dancers and non-dancers. Using an experimental approach, as well as a computational modeling approach, we are investigating the distinctive characteristics in dancers that may explain their lower incidence of acute lower extremity injuries.
