Keeogo Lower Limb Rehabilitation Exoskeleton

Developed through collaboration between Wistron Medical Technology and Canadian robotics firm B-Temia Inc., Keeogo (启而走) is an AI-powered lower limb exoskeleton designed for rehabilitation of patients with neurological conditions affecting mobility. The device distinguishes itself through dermoskeleton technology that augments rather than controls user movement, combined with an ultra-lightweight design at 6.8 kg—approximately half the weight of comparable devices.

Product Overview

Keeogo represents a powered knee orthosis category that B-Temia terms “dermoskeleton” to differentiate from traditional exoskeletons. While conventional powered exoskeletons move the user according to programmed patterns, Keeogo detects the wearer’s movement intentions through joint angle sensors and provides assistive force that follows natural motion. This approach maintains neural pathway engagement between the brain and muscles, potentially accelerating rehabilitation outcomes.

The system gained international recognition when French para-athlete Géraud Paillot wore Keeogo during the 2024 Paris Olympics torch relay. After 20 years with multiple sclerosis and significant walking difficulties, Paillot completed the relay in Saint-Malo, France, demonstrating the device’s capability to restore functional mobility.

Key Features

Cleared in the US (FDA 510(k)), Europe (CE), and China (NMPA 2024), Keeogo uses dermoskeleton technology to follow and assist natural knee movement at 6.8 kg — roughly half the weight of comparable lower limb exoskeletons.

• Ultra-Lightweight Construction: Total weight of 6.8 kg including battery, using carbon fiber shell components. Most competing lower limb exoskeletons weigh 14 kg or more.

• Dermoskeleton Technology: Unlike exoskeletons that dictate movement, Keeogo follows the user’s body, providing strength and support while the user controls the motion. This maintains brain-muscle neural connections during rehabilitation.

• AI Movement Detection: Proprietary artificial intelligence algorithms analyze hip and knee joint angle changes to predict user intent. This sensor approach at mechanical joints enables faster response than brain-interface detection methods requiring signal filtering.

• Servo Motor Assistance: Knee-mounted motors provide precise, adjustable power output based on user age, height, and muscle strength parameters configured via tablet application.

• Gamified Rehabilitation: Interactive training modules including virtual bowling, golf, and Tai Chi exercises make therapy sessions more engaging for patients.

• Real-Time Monitoring: Connected tablet displays step length, balance metrics, and motor force levels, building detailed rehabilitation profiles for clinical tracking.

Technical Specifications

Cleared across five markets including FDA 510(k) and NMPA (2024), Keeogo weighs 6.8 kg with a carbon fiber frame, using bilateral knee-mounted servo motors controlled through a tablet application and hip/knee joint angle sensing.

Clinical Applications

Keeogo supports rehabilitation for patients experiencing lower limb mobility impairments from various neurological conditions:

Stroke Rehabilitation: Assists post-stroke patients in regaining walking ability through repeated gait training with adjustable motor support levels.

Parkinson’s Disease: Provides stability and strength assistance for patients experiencing rigidity and movement initiation difficulties.

Multiple Sclerosis: Supports walking endurance for patients with MS-related fatigue and weakness, enabling longer training sessions.

Ankylosing Spondylitis: Assists patients with spinal mobility restrictions in maintaining ambulatory function.

The device functions for both institutional rehabilitation facilities and home use scenarios, with customizable settings for different user profiles.

Frequently Asked Questions

How does Keeogo differ from other rehabilitation exoskeletons?

Keeogo uses dermoskeleton technology where the device follows and assists the user’s movements rather than controlling them. This keeps the user actively engaged in initiating movement, maintaining brain-muscle connections important for neuroplasticity during rehabilitation. The 6.8 kg weight is also significantly lighter than most alternatives.

Can Keeogo be used at home or only in hospitals?

Keeogo is designed for both institutional rehabilitation settings and home use. The CE Mark for personal use in Europe indicates regulatory clearance for non-clinical environments. However, initial training and fitting typically occurs under professional supervision.

What activities can patients perform with Keeogo?

The device assists walking, running, stair climbing, lunging, and bending movements. Rehabilitation sessions can include gamified exercises like virtual bowling, golf, and Tai Chi to improve engagement and outcomes.
