My research focuses on understanding the neural and biomechanical factors involved in the normal control of multi-joint movement and posture and how these factors are modified following neuromotor pathologies such as stroke and spinal cord injury. The goal of this research is to provide a scientific basis for understanding normal and pathological motor control that can be used to guide rehabilitative strategies and user interface development for restoring function to individuals with motor deficits. A combination of experimentation, system identification and computer simulations is being used to achieve this goal.
Our lab is focused on the mechanisms underlying the multijoint control of movement and posture in able-bodied individuals and in individuals with neuromotor pathologies. Specifically, we are interested in understanding the relative contributions of intrinsic muscle properties, limb geometry and neural activation in the control of whole limb function.
