My clinical interests include adult neuro-rehabilitation and geriatric fall prevention. Currently my research focus is the potentially impaired multi-sensory integration mechanisms in individuals with balance deficits. By multi-sensory integration, we mean: how the brain puts together & uses information from the visual, vestibular and somatosensory systems to perceive how our bodies are oriented in and moving through space. How do we know where we are and where we are going?
One such balance-deficient group is the fall-prone elderly. My research has involved three groups of subjects: healthy young adults, healthy older adults, and fall-prone older adults. We have explored age-related changes in multisensory integration, as well as differences between healthy and fall-prone older adults that may be associated with a history or high risk of falls. I am also interested in how sensory-challenge balance exercise intervention programs may contribute to improved balance and reduce the risk of falls in the elderly.
