Congrats to Jane Guo for Obtaining her Master's Degree in BME!

Master's student Jane Guo has graduated with her thesis titled: "A Portable Eddy Current Braking Device for Upper-Extremity Functional Resistance Training", which she successfully defended on April 24th, 2017. An abstract of the work is presented below:

Loss of arm function is common in individuals with neurological damage, such as stroke or cerebral palsy. Robotic devices that address muscle strength deficits in a task-

specific manner can assist in the recovery of arm function; however, current devices are typically large, bulky, and expensive to be routinely used in the clinic or at home. To address this issue, we developed a portable, passive planar reaching robot using eddy current brakes. We then performed theoretical analysis of the robot’s resistive force generating capacity and steerable workspace using Matlab simulations. We also validated the device by having a subject move the end effector along different paths at a set velocity using a metronome while simultaneously collecting surface electromyography (EMG) and end-effector forces felt by the user. Results from simulation experiments indicated that the robot was capable of producing sufficient end-effector forces for functional resistance training. We also found the endpoint forces from the user were similar to the theoretical forces expected at any direction of motion. EMG results indicated that the device was capable of providing adjustable resistances based on subjects’ ability levels, as the muscle activation levels scaled with increasing magnet exposures. These results indicate that this upper extremity device is a promising approach to provide functional resistance training to the muscles along the upper extremity, but further testing is needed to determine the possible therapeutic benefits of this device.

The NeuRRo Lab and Peter Washabaugh Featured in AAAS Science Update Podcast

posted Nov 21, 2016, 8:01 AM by Edward Washabaugh

Edward "Peter" Washbaugh and the NeuRRo Lab were featured in the AAAS Science Update podcast that aired on November 17th. The interview focused on their work using self-powered robots to reduce slacking during therapy after stroke. These findings were presented at the 2016 Society for Neuroscience Conference that took place in San Diego California, and mark an exciting new development in the NeuRRo Lab.

NeuRRo Lab's SFN Presentation has been Selected as a Hot Topic

posted Aug 16, 2016, 12:15 PM by Chandramouli Krishnan   [ updated Aug 16, 2016, 3:26 PM by Edward Washabaugh ]

Robotic rehabilitation is a promising approach to recover lost functions after stroke or other neurological disorders; however, “motor slacking” – a phenomenon where the motor system reduces muscle activation levels and movement excursions to minimize metabolic and movement related costs – is a known limitation of externally driven robots. Research at the NeuRRo Lab tested the hypothesis that motor slacking could be effectively minimized if individuals provide the power to move the limb via their own body power (e.g., from their opposite limb). This presentation (Title: Self-powered robots to minimize motor slacking during rehabilitation) has been selected as a Neuroscience 2016 Hot Topic and will be included in this year's (2016) Hot Topics book. Peter Washabaugh will be presenting this work at the Neuroscience 2016 (SFN).  This work was funded by NIH Grant# R01 EB019834. For more information and include this work in your meeting planner, please visit: SFN abstract

E. Peter Washabaugh receives NSF Graduate Research Fellowship Award

posted Mar 30, 2016, 7:33 AM by E. Peter Washabaugh   [ updated Mar 31, 2016, 8:14 AM by Chandramouli Krishnan ]

Edward Peter Washabaugh has been awarded the prestigious National Science Foundation (NSF) Graduate Research Fellowship Award (2016). NSF Fellows are selected based on their potential to become globally engaged knowledge experts and leaders who can contribute
significantly to research, education, and innovations in science and engineering. Peter was selected competitively among 17000 applicants, by a panel of experts for his proposed research work on a novel gait training paradigm for stroke survivors. Specifically, the proposed work involves developing a wearable resistive robotic brace for gait therapy, and performing a series of experiments to (1) test the efficacy of the device versus other methods of resistive gait training, (2) evaluate the device's potential to induce neural plasticity, and (3) evaluate the take home potential and cumulative therapeutic effects of robotic functional strength training. Peter is currently pursuing a doctoral degree in Biomedical Engineering under the mentorship of Dr. Chandramouli Krishnan at Physical Medicine & Rehabilitation. He is one among two who received the fellowship this year in BME and is the first in Physical Medicine & Rehabilitation to earn this distinction. The mission of the University of Michigan Department of Physical Medicine and Rehabilitation ( is to maximize the health, function and quality of life of individuals with acute and chronic illness and disability in the local and global community throughout their life span through innovative research, education, advocacy and interdisciplinary clinical practice. Peter's work fits well with this mission and we wish him more success in his endeavors!
