ExoMotus Lower Limb Exoskeleton

Fourier Rehabilitation Ecosystem: ArmMotus M2 (Upper Limb) | ExoMotus (Lower Limb) | RehabHub (Integrated Platform)

ExoMotus represents Fourier Intelligence’s flagship lower limb exoskeleton system, designed to provide powered gait rehabilitation for patients with spinal cord injuries, stroke, and other neurological conditions affecting mobility. The system combines intelligent actuator technology with built-in safety features for clinical and research applications.

Product Overview

ExoMotus enables patients who have lost lower limb function to perform repetitive, intensive gait training with robotic assistance. Unlike passive orthoses, the powered exoskeleton actively drives hip and knee joints through physiologically appropriate walking patterns, facilitating neuroplasticity and motor relearning.

The system builds on Fourier’s core competency in force feedback technology, originally developed for upper limb rehabilitation. ExoMotus translates this expertise to lower extremity applications, providing precisely controlled assistance that adapts to each patient’s capability level and therapeutic goals.

Key Features

Torque Safety Protection System: Built-in safety mechanisms continuously monitor joint angles and torques, automatically limiting motion if parameters exceed safe thresholds. This prevents falls and joint injuries during therapy sessions.

Intelligent Modular Battery: The battery management system enables approximately 8 hours of continuous walking operation on a single charge. Modular design allows quick battery swaps in clinical settings.

Multi-Device Integration: ExoMotus supports connectivity with augmented reality headsets, EEG brain-computer interface caps, and other intelligent devices. This enables intention-based control and enhanced training engagement through multimodal feedback.

EXOPS Compatibility: As part of the Exoskeleton Robot Open Platform developed with National Instruments and University of Melbourne, ExoMotus supports secondary development and research customization.

Technical Specifications

ExoMotus is Fourier Intelligence’s CE-marked lower limb exoskeleton for spinal cord injury and stroke rehabilitation, supporting users 150–190 cm tall and up to 100 kg through powered hip and knee joints.

Clinical Applications

ExoMotus addresses multiple clinical scenarios requiring lower limb rehabilitation:

Spinal Cord Injury: Patients with complete or incomplete SCI from T6 to L2 level can achieve standing and walking function with robotic assistance. The system supports progression from fully assisted movement to reduced assistance as neurological recovery occurs.

Stroke Rehabilitation: Hemiplegic patients benefit from symmetrical gait pattern training. The bilateral design ensures affected and unaffected limbs move in coordinated patterns.

Multiple Sclerosis and Parkinson’s Disease: Patients with progressive neurological conditions can maintain walking function and delay mobility decline through regular exoskeleton-assisted training.

Research Applications: Academic institutions use ExoMotus through the EXOPS platform to investigate gait biomechanics, motor learning, and neuroplasticity mechanisms.

Regulatory Status

ExoMotus is commercially available and has been deployed in hospitals and rehabilitation centers across more than 40 countries. The system is part of Fourier’s RehabHub integrated platform, enabling direct data sharing with other rehabilitation devices.

Frequently Asked Questions

What conditions can ExoMotus treat?

ExoMotus is indicated for gait rehabilitation in patients with spinal cord injury (T6-L2 level), stroke with hemiplegia, multiple sclerosis, Parkinson’s disease, and other neurological conditions affecting lower limb function. Patient selection should be performed by qualified rehabilitation physicians.

How does ExoMotus compare to other exoskeletons?

ExoMotus distinguishes itself through integration with Fourier’s broader rehabilitation ecosystem, support for multi-device connectivity (AR, EEG), and the open EXOPS research platform. Battery life of approximately 8 hours exceeds many competing systems.

What training is required for clinicians?

Fourier provides full training programs for rehabilitation therapists and physicians. Training covers device operation, patient fitting and adjustment, therapy protocol design, and safety procedures.
