Scientific Foundation
COSIMA is built on decades of research conducted at the Pavlov Institute of Physiology of the Russian Academy of Sciences—one of the country’s oldest and most respected scientific institutions in the field of neurophysiology.
The company’s Scientific Director is Yuri Petrovich Gerasimenko, Corresponding Member of the Russian Academy of Sciences, Doctor of Biological Sciences, and Head of the Laboratory of Movement Physiology. A globally recognized expert, his research in spinal cord neurophysiology is widely cited in leading international journals and has helped shape the direction of modern neurorehabilitation.
Under his leadership, a multidisciplinary team of researchers has been formed, including T.R. Moshonkina, S. Ananyev, A. Grishin, and other specialists. Together, they combine deep фундаментal expertise with extensive clinical experience, ensuring the effective translation of scientific discoveries into real-world rehabilitation practice.
From Lab to Patient
The journey from scientific discovery to a fully functional medical device has taken years
Experiments
demonstrating the fundamental possibility of activating spinal locomotor neural networks through non-invasive stimulation
Development
Followed by the development of optimal stimulation parameters — including waveform, frequency, and electrode placement.
Development of Scalable Medical Devices
And ultimately — the development of production-grade equipment that has undergone all required testing and received registration from Roszdravnadzor.
Today, our technologies are protected by patents and supported by publications in peer-reviewed scientific journals. Most importantly, their effectiveness is proven by the patients who have regained the ability to stand and walk.
How It Works
Transcutaneous Electrical Spinal Cord Stimulation
  • Our Core Method
    Multilevel Non-Invasive Spinal Cord Stimulation
    The name is long, but the concept is simple: we stimulate the spinal cord through the skin—without surgery—targeting multiple levels of the spine simultaneously.
  • How It Works in Practice
    Electrodes are placed on specific points along the patient’s spine—over the segments of the spinal cord responsible for limb movement. The device generates specially designed electrical impulses that pass through the skin and soft tissues, reach the spinal neural structures, and activate the spinal locomotor networks.
  • What Happens Next
    Locomotor networks are “movement programs” embedded in the spinal cord. In a healthy person, they function automatically—we don’t consciously think about which muscle to activate with each step. After an injury or stroke, these programs lose their connection to the brain, but they do not disappear. Our stimulation replaces the lost control signals, externally triggering these programs.
Why This Is Better Than Exoskeletons

An exoskeleton is an external mechanical frame that moves a patient’s limbs using motors. The patient remains passive—the machine moves their legs. While this is better than being immobile, it does not restore the patient’s own neural connections.

Our approach is fundamentally different. We don’t move the patient—we help them move themselves. Electrical stimulation activates their muscles through their own neural networks. This creates natural movement, training and strengthening the nervous system while triggering neuroplasticity—the brain’s ability to relearn and restore lost functions.

Additionally, exoskeletons weigh 25–30 kilograms, whereas our equipment is portable and lightweight.
Proven Effectiveness
Our technologies have been tested and validated in leading medical institutions in Russia.
  • Medical and Diagnostic Center of the Federal Research Clinical Center of FMBA
  • Research Clinical Center No. 2 of the Petrovsky Russian Scientific Center of Surgery, named after Academician B.V. Petrovsky
  • G.I. Turner National Institute of Pediatric Orthopedics and Traumatology
  • V.A. Almazov National Medical Research Center
  • City Hospital No. 40 (Saint Petersburg, Russia)
  • Scientific Center of Neurology (Moscow, Russia)
What We See in the Clinic
  • In patients in the intensive care units:
    • Restoration of independent breathing in patients previously on mechanical ventilation
    • Stabilization of blood pressure
    • Reduction of ICU stay duration
  • In patients with paresis and paralysis:
    • Increased range of limb movements
    • Enhanced muscle strength
    • Reduction of spasticity
    • Improved walking coordination
    • Restoration of sensation
    • Normalization of pelvic organ function
In Children with Cerebral Palsy: Clinical trials of the electrode suit at the G.I. Turner National Institute of Pediatric Orthopedics and Traumatology demonstrated high effectiveness in restoring motor functions in pediatric patients—one of the most challenging groups for rehabilitation.
COSIMA is a resident of the Skolkovo Biomedical Cluster, highlighting the innovative nature of our developments and providing access to cutting-edge scientific and technical infrastructure.
A joint project with NeuroChat — “Movement is Life” — was selected as one of the 20 finalists in the Skolkovo accelerator competition “Innovations in Rehabilitation”.
More than 50 COSIMA devices are in operation abroad — in the USA, Canada, and Europe. Our technologies are in demand where advanced neurorehabilitation is being developed.
All COSIMA equipment is registered with Roszdravnadzor and complies with the requirements of the Russian Ministry of Health.
Our systems are recommended for use in:
  • Medical and preventive institutions
  • Medical rehabilitation centers
  • Sanatoriums
  • Intensive care and ICU units
  • Home settings under specialist supervision
