A NEUROSTIMULATION SYSTEM FOR CLINICAL
REHABILITATION AFTER SPINAL CORD INJURY
STIMUS
A system that enables controlled generation and reproducible delivery of stimulation patterns, based on physiological principles of spinal cord function, within clinical and pilot rehabilitation protocols.
* Stimus is currently in R&D / pre-clinical stage. Use is limited to approved clinical pilots and rehabilitation protocols under the responsibility of a qualified medical professional.
WHY SPINAL CORD INJURY REHABILITATION STILL DEPENDS ON PROTOCOL LIMITATIONS?
Rehabilitation after spinal cord injury (SCI) requires long-term programs, highly qualified clinical staff, and repeatable therapeutic procedures. Clinics and research centers need neuromodulation tools that allow controlled reproduction of stimulation patterns, protocol scalability, and safe experimentation within clinical pilots and studies.
Spinal Cord Injury Rehabilitation Key Challenges
High cost
of long-term rehabilitation programs
Variability
of outcomes due to inconsistent stimulation approaches
Limited
repeatability and standardization of stimulation sessions
STIMUS: A SOLUTION FOR COMMON REHABILITATION PROBLEMS
Stimus is designed as a neurostimulation system that helps clinics define, control, and reproducibly apply stimulation parameters throughout rehabilitation after spinal cord injury.
The system enables stimulation patterns based on physiological principles of spinal cord function and supports their use within approved clinical and pilot protocols — reducing session-to-session variability and simplifying long-term rehabilitation workflows.
Stimus key advantages
Controlled and reproducible stimulation
Defined parameters can be consistently applied across sessions within a rehabilitation protocol.
Engineered for safety and comfort
With galvanically isolated channels and a controlled maximum output of 50 mA, the treatment is both safe and painless.
Flexible multi-channel configuration
32 galvanically isolated channels allow adaptation of stimulation to specific rehabilitation scenarios.
Support for clinical pilots and research
Suitable for safe testing and refinement of neurostimulation protocols in real clinical environments.
Stimus modulates neural circuits within the spinal cord that are responsible for motor pattern formation, rather than inducing direct muscle contraction. It represents a different approach focused on modulating spinal neural circuits involved in motor control, and is used as part of structured rehabilitation protocols.
HOW ELECTRICAL STIMULATION WITH STIMUS WORKS?
During a rehabilitation session, Stimus delivers controlled electrical impulses to selected areas associated with motor function.
The goal of stimulation is to modulate neural circuits within the spinal cord that contribute to the generation and support of movement.
Preparation & setup
Before the session, the clinician:
- places stimulation electrodes,
- selects a stimulation mode according to the rehabilitation protocol,
- adjusts stimulation parameters for the specific therapeutic task.
Delivery of electrical impulses
During the session, Stimus delivers sequences of electrical impulses via a multi-channel stimulation system.
These impulses:
- interact with spinal neural structures,
- modulate activity of neural circuits related to motor function,
- are applied in combination with rehabilitation exercises.
(The stimulation does not force movement, but supports the activity of neural circuits.)
Integration into rehabilitation
- as part of a rehabilitation session,
- together with active or assisted therapy,
- within a repeatable and controlled protocol.
This enables clinicians to apply stimulation consistently throughout the rehabilitation course and assess patient dynamics over time.
TECHNOLOGY & KEY CHARACHTERISTICS
The stimulation logic of Stimus is built around an algorithm inspired by spiking neural network models, allowing electrical impulses to be delivered in structured temporal patterns. This approach supports controlled and repeatable neuromodulation of spinal neural circuits during rehabilitation sessions, without relying on fixed or muscle-specific stimulation patterns.

FREQUENTLY ASKED QUESTIONS
Electrical stimulation interacts with neural structures of the spinal cord, influencing excitability and coordination of neural circuits associated with motor function.
No. Electrical neurostimulation does not force movement. It supports neural circuit activity and is used together with voluntary or assisted rehabilitation exercises.
When used within approved protocols, under professional supervision and with appropriate safety measures, electrical neurostimulation is considered suitable for clinical rehabilitation settings.
Reproducible stimulation refers to the ability to apply the same stimulation parameters consistently across sessions, supporting standardized rehabilitation protocols and outcome assessment.
Reproducibility reduces variability between sessions and clinicians, allowing more consistent application of rehabilitation protocols and clearer interpretation of patient progress.
A clinical pilot is a structured, limited clinical use of a neurostimulation system to evaluate feasibility, workflow integration, and protocol refinement under controlled conditions.
Multi-channel neurostimulation allows electrical impulses to be delivered through multiple independent channels, enabling flexible distribution of stimulation.
Multi-channel systems provide greater flexibility in targeting neural structures and supporting different rehabilitation scenarios.
No. Electrical neurostimulation complements conventional rehabilitation therapy and does not replace physiotherapy or clinical decision-making.
