Milos R. Popovic
Contributions to stroke and spinal cord injury rehabilitation
Milos R Popovic is a scientist focused in Functional Electrical Stimulation (FES) and neurorehabilitation. As of 2018, Popovic is the Director of the Research Institute at UHN Toronto Rehabilitation Institute (TRI), and a Professor with the Institute of Biomaterials and Biomedical Engineering at the University of Toronto. MyndTec is a company started by Popovic that develops the FES technology for individuals with paralysis due to stroke or spinal injury

Popovic received a Dipl. of Electrical Engineering from the University of Belgrade in his native Serbia in 1990. He then earned his Ph.D in Mechanical Engineering from the University of Toronto in 1996... His Ph.D thesis was on Friction modelling and control under supervision of Andrew Goldenberg.
In July 2001, Popovic established The Rehabilitation Engineering Laboratory (REL) at the Lyndhurst Centre of Toronto Rehabilitation Institute. REL is devoted to advancement of the field of rehabilitation engineering. It supports multiple research groups, including the Popovic lab, under supervision of 6 principal investigators. Their research focuses on development of rehabilitation and assistive technologies to restore lost functionality due to nervous tissue injury. In 2018, Popovic was appointed as TRI's Director of Research. He is also the leader of the Neural Engineering and Therapeutics research team at iDAPT (Intelligent Design for Adaptation, Participation, and Technology), which is focused on translation of rehabilitative research info advanced therapeutic tools. Some of his major scientific contributions are outlined below.
Functional Electrical Stimulation as a Rehabilitative Tool
Functional Electrical Stimulation (FES) uses bursts of short electrical pulses to generate muscle contraction. Application of these electrical pulses to motor nerves results in generation of an action potential along the axon of that nerve towards its targeted muscle. With electrodes placed on the skin over the desired muscle, individuals attempt to move their muscle by sending a signal with their brain to the muscle. The muscle is then stimulated by the system, causing a contraction which sends a signal from the muscle to the brain. Thus, a new neural pathway is formed, which improves recovery of voluntary movement.
Popovic has led studies investigating the use of FES in the rehabilitation of muscular function for stroke victims with extremely limited arm and hand mobility in comparison with conventional therapy. One of the most well-known publications is "Rehabilitation of Reaching and Grasping Function in Severe Hemiplegic Patients Using Functional Electrical Stimulation Therapy", conducted in 2008. Electrical impulses to activate muscles were used in combination with verbal cues, and over the course of the treatment period, less FES was necessary to achieve the desired movements. Patients using FES in the study showed significant improvement in object manipulation, palmar grip torque, and pinch grip pulling force when compared to those using only conventional therapy. This research aligned with the development of the company MyndTec.
Under his supervision, projects at REL have also investigated use of electrical stimulation for restoring various functionalities commonly lost due to nervous tissue injury, such as restoration of swallowing, balance during standing and sitting. REL also developed methods to reduce muscle fatigue that results from FES-based therapies through optimization and randomization of electrical stimulation parameters
Popovic is also involved in the development of various brain-machine interfaces (BMI) for use in humans, using implantable electrocorticographic (ECoG) and surface electroencephalographic (EEG) electrode. A neuroprosthesis study conducted using ECoG achieved high accuracy in producing intended grasp-and-release functionality in the hand . Real-time asynchronous control of a remote-controlled car was achieved using a single EEG electrode to eliminate restrictions related to information transfer rates. Work within this field tests the feasibility and functionality of using invasive and non-invasive physiological signals to improve implementation of FES as a rehabilitation method.
Spinal Cord Injury Therapies
Popovic is a dedicated advocate for awareness and therapeutic advancement for spinal cord injuries (SCI). In 2004, he was a co-founder of the Canadian National Spinal Cord Injury Conference, and since acts as a co-chair for the annual event. As part of his work with iDAPT, he's also contributed to the Spinal Cord Injury: A Manifesto for Change. The manifest is a call to action to improve the care of people living with SCI.
Compex Motion Simulator
Popovic developed Compex Motion, a portable and programmable system used for transcutaneous FES, in collaboration with Swiss company Compex SA. The stimulator can be programmed to generate a variety of stimulation sequences, can be connected to other systems to increase channel capabilities, and can be controlled externally. The device can be used in the development of neuroprostheses, and muscle exercise systems. This work provided the foundation for the use of FES in SCI rehabilitation.
Popovic has played a large role in the professional development of researchers and students. He is also part of several international and domestic academic committees and has supervised over 20 postdoctoral fellows, 24 PhD students, 36 Masters students, and many undergraduate thesis and summer research projects. In addition to supervisory roles, Popovic has given over 200 guest lectures and led 25 workshops; he frequently gives lectures at the University of Toronto to undergraduate and graduate level courses.
In 2008, Popovic co-founded MyndTec based on the FES system that has been a focus of his research. MyndTec is a medical technology company that develops MyndMove, a transcutaneous FES therapy to improve function and maximize independence for patients with stroke- and spinal-cord injury-related paralysis. MyndMove therapy session employ a variety of reaching and grasping protocols that permit patients to regain voluntary arm and hand movement.
Through Popovic's product development work both within TRI and MyndTec, he has several patents related to FES methods and devices . In 2014, the Functional electrical stimulation device and system, and use thereof filed by University Health Network got approved. In 2018, his work within MyndTec Inc., the wireless implantable data communication system, method and sensing device was granted
Popovic has been featured in several news stories, as well as televised and broadcast interviews on local media outlets to discuss his work. In 2015, he discussed the use of FES in stroke and spinal cord injury rehabilitation. In 2018, his FES device MyndMove was featured as a technology for paralysis. He was also featured on a tour of iDAPT at TRI, to discuss the lab space and current research.
