SIASUN Lower Limb Powered Exoskeleton Robot

Developed by SIASUN, the Lower Limb Powered Exoskeleton Robot enables patients with severe lower limb impairments to progress from complete immobility to assisted upright walking. Electric motors drive the hip, knee, and ankle joints while integrated safety systems and customizable training parameters support rehabilitation across multiple patient populations.

Product Overview

The SIASUN Lower Limb Powered Exoskeleton addresses a critical need in neurological rehabilitation: restoring walking ability for patients who cannot initiate voluntary leg movement. Unlike passive exoskeletons that augment residual strength, this powered system provides full motor assistance at three joint levels, enabling therapeutic gait training even for patients with complete paralysis.

The device integrates with mobile support frames during early rehabilitation stages, ensuring stability as patients regain confidence and motor control. As recovery progresses, the level of robotic assistance can be gradually reduced to encourage active patient participation.

Key Features

At all three gait joints, SIASUN’s Lower Limb Exoskeleton drives hip, knee, and ankle movement independently, enabling assisted walking for patients with complete paralysis from stroke or spinal cord injury.

Three-Joint Motorized Assistance: Electric actuators drive the hip, knee, and ankle joints independently, reproducing natural gait kinematics during walking exercises.

Multiple Control Modes: Therapists can select from various control strategies based on patient capability—from fully passive movement to active-assisted modes that respond to patient-initiated motion.

Customizable Training Parameters: Step length, cadence, joint range of motion, and assistance levels can be adjusted for individual patients and modified as rehabilitation progresses.

Mobile Support Frame Integration: For early-stage patients, the exoskeleton works in conjunction with wheeled support frames that provide stability and fall prevention.

Fall Protection System: Integrated safety mechanisms detect loss of balance and respond with protective measures to prevent patient injury.

Clinical Applications

The powered exoskeleton targets patients requiring intensive gait rehabilitation:

Stroke Recovery: Post-stroke patients with hemiplegia or severe weakness benefit from early mobilization and repetitive gait training that promotes neuroplasticity.

Spinal Cord Injury: Patients with incomplete spinal cord injuries can use the device to maintain joint mobility and muscle tone while working toward independent walking.

Post-Surgical Rehabilitation: Following major lower limb or spinal surgery, the exoskeleton supports protected weight-bearing exercises during recovery.

Neurological Conditions: Patients with traumatic brain injury, multiple sclerosis, or other conditions affecting motor control can use the system for gait retraining.

The device is designed for use in hospital rehabilitation departments and specialized rehabilitation centers under professional supervision.

Frequently Asked Questions

What conditions can the SIASUN exoskeleton treat?

The device is designed for rehabilitation of lower limb motor impairment resulting from stroke, spinal cord injury, post-surgical recovery, and various neurological conditions affecting walking ability.

Can patients use this device at home?

No, the Lower Limb Powered Exoskeleton is designed for clinical use under professional supervision. SIASUN offers separate home-use products including the Wearable Lower Limb Walker for independent daily use.

How does this compare to other rehabilitation exoskeletons?

SIASUN’s powered exoskeleton provides motorized assistance at three joint levels (hip, knee, ankle), similar to international products like ReWalk and Ekso. The device is positioned as a domestically manufactured alternative for the Chinese healthcare market.
