About

Eric J. Perreault is a Professor of Biomedical Engineering at Northwestern University. His research group focuses on understanding the neural and biomechanical factors involved in the normal control of multi-joint movement and posture, as well as how these factors are modified following neuromotor pathologies such as stroke and spinal cord injury. The goal of his 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. His work employs a combination of experimentation, computer simulations, and machine learning to achieve these objectives.

  Senior authorCorresponding

  It is generally accepted that the number of neurons in a given brain area far exceeds the number of neurons needed to carry any specific function controlled by that area. For example, motor areas of the human brain contain tens of millions of neurons that control the activation of tens or at most hundreds of muscles. This massive redundancy implies the covariation of many neurons, which constrains the population activity to a low-dimensional manifold within the space of all possible patterns of…

• Haptic Transparency and Interaction Force Control for a Lower Limb Exoskeleton

  IEEE Transactions on Robotics · 2024-01-01 · 46 citations

  article

  Controlling the interaction forces between a human and an exoskeleton is crucial for providing transparency or adjusting assistance or resistance levels. However, it is an open problem to control the interaction forces of lower-limb exoskeletons designed for unrestricted overground walking. For these types of exoskeletons, it is challenging to implement force/torque sensors at every contact between the user and the exoskeleton for direct force measurement. Moreover, it is important to compensate…

• Consensus for experimental design in electromyography (CEDE) project: Checklist for reporting and critically appraising studies using EMG (CEDE-Check)

  Journal of Electromyography and Kinesiology · 2024-03-13 · 38 citations

  articleOpen access

  The diversity in electromyography (EMG) techniques and their reporting present significant challenges across multiple disciplines in research and clinical practice, where EMG is commonly used. To address these challenges and augment the reproducibility and interpretation of studies using EMG, the Consensus for Experimental Design in Electromyography (CEDE) project has developed a checklist (CEDE-Check) to assist researchers to thoroughly report their EMG methodologies. Development involved a mul…

• Grand Challenges at the Interface of Engineering and Medicine

  IEEE Open Journal of Engineering in Medicine and Biology · 2024-01-01 · 22 citations

  articleOpen access

  Over the past two decades Biomedical Engineering has emerged as a major discipline that bridges societal needs of human health care with the development of novel technologies. Every medical institution is now equipped at varying degrees of sophistication with the ability to monitor human health in both non-invasive and invasive modes. The multiple scales at which human physiology can be interrogated provide a profound perspective on health and disease. We are at the nexus of creating "avatars" (…
