ArmMotus M2 Upper Limb Rehabilitation Robot

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

ArmMotus M2 was China’s first commercially available upper limb rehabilitation robot based on force feedback technology. Developed by Fourier Intelligence, the system provides precision-controlled assistance and resistance during upper extremity therapy, with gamified training protocols to enhance patient engagement and outcomes.

Product Overview

The ArmMotus M2 addresses the critical need for intensive, repetitive upper limb training in stroke and neurological rehabilitation. Traditional therapy requires significant therapist effort to provide consistent, graduated assistance. ArmMotus automates this process while capturing detailed performance data for outcome tracking and treatment optimization.

The core innovation lies in Fourier’s proprietary force feedback actuator technology. Unlike simple passive devices, ArmMotus provides bidirectional force control, allowing the system to assist weak movements, resist strong movements, and create variable impedance environments that challenge patients appropriately throughout recovery.

Key Features

Force Feedback Control: The system delivers precise, programmable forces across the workspace, enabling assist-as-needed therapy protocols. Therapists can set assistance levels, resistance parameters, and target trajectories customized to each patient’s ability.

Gamified Training Interface: Interactive games and exercises maintain patient motivation during repetitive training sessions. Visual feedback displays real-time performance metrics including trajectory accuracy, force production, and movement smoothness.

Session Data Analytics: All training sessions are automatically logged with detailed kinematic and kinetic data. Therapists can track progress over time, compare sessions, and generate reports for clinical documentation and research.

RehabHub Integration: ArmMotus connects directly with other Fourier rehabilitation devices through the RehabHub platform, enabling coordinated multi-device therapy protocols and centralized data management.

Technical Specifications

Designed for stroke and traumatic brain injury recovery, ArmMotus M2 from Fourier Intelligence operates on 2 degrees of freedom in a planar workspace with bidirectional force output and CE certification across 40+ countries.

Clinical Applications

ArmMotus M2 supports rehabilitation across multiple patient populations and therapy goals:

Stroke Recovery: Hemiparetic patients train reaching and manipulation movements in the horizontal plane. The system provides graded assistance based on real-time force measurements, reducing assistance as function improves.

Traumatic Brain Injury: Patients with motor deficits following TBI benefit from high-intensity, repetitive practice. Game-based protocols maintain engagement during cognitively demanding recovery periods.

Neurodegenerative Conditions: Patients with Parkinson’s disease, multiple sclerosis, and other progressive conditions can maintain upper limb function through regular robotic training.

Orthopedic Recovery: Post-surgical patients requiring range of motion and strength restoration can use ArmMotus with resistance-focused protocols.

Regulatory Status

ArmMotus is commercially available in over 40 countries as part of Fourier’s global rehabilitation robotics portfolio. The system is deployed in hospitals, rehabilitation centers, and research institutions worldwide.

Frequently Asked Questions

What patient populations can use ArmMotus M2?

ArmMotus M2 is appropriate for patients with upper limb impairment due to stroke, traumatic brain injury, spinal cord injury, multiple sclerosis, Parkinson’s disease, and orthopedic conditions. Patients should have sufficient cognitive function to engage with training games and follow instructions.

How long are typical therapy sessions?

Session duration varies based on patient tolerance and therapy goals, typically ranging from 30 to 60 minutes. The system tracks fatigue indicators and can suggest session endpoints based on performance decline.

Can ArmMotus data be exported for research?

Yes, the system supports data export in standard formats for clinical research and outcome studies. The EXOPS open platform enables additional customization for academic research applications.
