The Laboratory for Integrative Motor Behavior

Research in the LIMB lab seeks to discover fundamental principles of biomechanics and motor control, interpret these principles in the context of the physical and occupational environment, and apply basic research discoveries to problems in biomedicine and public health.

Current research areas:

(1) characterizing the dynamic requirements for maintaining stability and maneuvering during locomotion
(2) discovering the behavioral strategies for controlling unsteady locomotion, and the relative roles of musculoskeletal properties and neural output in maneuvering and stability
(3) using biomechanics to prevent workplace injury (see also www.healthydevices.org)
(4) developing methods to quantitatively assess locomotor and upper-extremity function following neuromotor impairment such as spinal cord injury, stroke, and traumatic brain injury
(5) developing and evaluating novel approaches for restoring motor function following spinal cord injury; and
(6) understanding the mechanisms of spinal learning.

We use comparative experimental studies using a diversity of animals (humans, rodents, primates, insects, birds) to develop and test conceptual and mathematical models. Biomechanical (kinematics, force) and neurophysiological (EMG) measurements describe motor control, and are interpreted in the context of musculoskeletal and neural anatomy and function. Computer simulations can also be valuable tools for hypothesis generation, sensitivity analysis, and engineering design. Overall, the laboratory is committed to using discoveries from basic research to prevent injuries, and develop effective methods for rehabilitation and functional restoration following neuromotor injury. We also seek to develop new and interesting ways to communicate the excitement of new discoveries (www.thinkinginmotion.org).
