The main objective of the lab is to identify the neural, musculo-skeletal and psychological factors that contribute to balance deficits and falls associated with age, Parkinson’s disease, vestibular loss and spinal cord injury. The second objective is to identify optimal exercise, training and treatment strategies to improve age and disease-specific balance deficits and reduce the occurrence and impact of falls.
The Neural Control of Posture and Movement Laboratory features a comprehensive approach to studying dynamic control of balance by combining various neuro-physiological and biomechanical techniques, including surface and intra-muscular electromyography, 3D full-body motion analysis and force measurement coupled with quantitative and qualitative assessment of perceived and physiological effects of fear and anxiety. Virtual environments have been integrated with unique moving balance platforms to manipulate balance-related anxiety and recreate the environmental conditions that lead to falls in everyday life.
Fear of Falling and Postural Control
Postural threat is manipulated by having participants stand on either real or virtual heights. This approach allows us to examine how changes in fear, anxiety and arousal may directly contribute to balance deficits and falls.
Origins of Balance Disorders
Using unique moving platforms designed to mimic real-life conditions that lead to falls, we are trying to identify the specific factors that may contribute to balance deficits in patients with balance disorders such as Parkinson’s disease, vestibular loss and spinal cord injury.
Postural Control of the Trunk
This research aims to understand the relative contribution of deep and superficial muscles of the trunk in normal and pathological control of reactive and anticipatory balance.

Originally from southern Ontario, Taylor completed a bachelor’s degree at Brock University, majoring in Kinesiology, before moving to Vancouver to complete his master’s degree with Dr. Carpenter. During his MSc, Taylor’s research was used to validate the use of virtual reality as a novel method to induce states of increased fear and arousal, as well as examine the effects of fear on static and dynamic balance. More recently, his doctoral work has focused on understanding the influence of fear, anxiety, and physiological arousal on cortical processing and behavioural characteristics related to perceptions of somatosensory, vestibular and visual inputs during postural tasks.
Martin completed his Bachelor’s and Master’s degrees at Brock University in St. Catharine’s, Ontario. During this time, his research focused on understanding how personality and cognitive factors influence individuals’ behaviour when maintaining balance in situations where there is an increased consequence of falling. For his doctoral work, Martin is investigating the cognitive, physiological, and behavioural adaptations that individuals experience when repeatedly exposed to similar threat scenarios. His goal is to elucidate some of the psychological and physiological mechanisms underlying the relationship between postural threat and human balance control, as well as guide interventions for individuals whom experience anxiety associated with falling on a daily basis (e.g., frail elderly, individuals with neurological deficits).
Eveline is a PhD student in UBC's School of Kinesiology. She completed her medical degree in The Netherlands at the Radboud University Nijmegen. Her research focus is on balance impairment in patients with Parkinson's disease using different research techniques, including functional MRI. In her spare time, Eveline enjoys playing field hockey, sailing and kiteboarding. She's currently on leave from her PhD program to get experience working as a Neurology resident-not-in-training in the Spaarne Gasthuis hospital in Haarlem, The Netherlands.
