AiKang Lower Limb Exoskeleton Robot

AiKang represents Ai-Robotics’ portable lower-limb exoskeleton system designed for mid-to-late stage rehabilitation, enabling patients to perform overground walking training with elbow crutch support. As one of the first two NMPA-certified exoskeleton robots in China (June 2018), AiKang focuses on scientific gait correction and muscle strength improvement for patients progressing beyond early recovery stages.

Product Overview

Designated internally as the “All-Round King,” AiKang addresses the rehabilitation needs of patients who have progressed past the initial treatment phase and require structured gait training to restore functional walking ability. Unlike frame-mounted systems designed for early recovery, AiKang is a wearable device that allows patients to practice walking on real ground surfaces while using elbow crutches for balance support.

The system received NMPA Class II medical device registration in June 2018 alongside the AiDong product, establishing Ai-Robotics as the first domestic manufacturer to achieve regulatory approval for lower-limb exoskeleton robots in China.

Key Features

Approved under China’s NMPA Class II in June 2018, Ai-Robotics’ AiKang is a wearable lower-limb exoskeleton for mid-to-late stage gait rehabilitation, used with elbow crutches on real ground surfaces.

• Portable design: Wearable structure without external frame, enabling overground walking practice
• Elbow crutch integration: Designed to work with standard elbow crutches for balance maintenance
• Scientific gait training: Programmed walking patterns based on normal human gait biomechanics
• Multi-joint actuation: Hip and knee joint motors provide coordinated assistance during walking
• Progressive training protocols: Adjustable assistance levels to match patient recovery progression
• Real-time monitoring: Sensors track walking parameters including step length, cadence, and joint angles

Technical Specifications

Approved under China’s NMPA Class II in June 2018, AiKang actuates hip and knee joints in passive, power-assisted, and active modes on overground surfaces with elbow crutch balance support.

Clinical Applications

AiKang is indicated for patients with lower limb motor dysfunction who have completed early-stage rehabilitation:

Target patient populations:

• Spinal cord injury patients (paraplegia) in mid-to-late recovery
• Stroke patients (hemiplegia) transitioning from bed-based to ambulatory training
• Cerebral palsy patients requiring gait pattern correction
• Patients with progressive muscle weakness
• Individuals with lower limb degeneration due to aging

Rehabilitation objectives:

• Correct abnormal gait patterns established during injury compensation
• Improve joint range of motion and flexibility
• Strengthen lower limb muscle groups through repetitive walking
• Rebuild neurological pathways through motor relearning
• Enhance cardiovascular function through upright activity

Clinical data from partnering hospitals including Beijing Jishuitan Hospital, Beijing Xuanwu Hospital, and Jiangsu Provincial People’s Hospital have demonstrated gait improvement in patients undergoing structured AiKang training programs.

Regulatory Status

AiKang was approved under China’s expedited “green channel” review pathway for innovative medical devices. The product is included in provincial medical insurance coverage in Beijing and Shaanxi provinces.

Frequently Asked Questions

What is the difference between AiKang and AiDong?

AiDong is a frame-mounted exoskeleton (approximately 80kg) designed for early-stage rehabilitation, allowing suspended or supported walking for patients who cannot bear their own weight. AiKang is a portable, wearable system for mid-to-late stage patients who can partially support themselves with crutches. Patients typically progress from AiDong to AiKang as their recovery advances.

How long does AiKang rehabilitation typically take?

According to Ai-Robotics clinical data, patients undergoing structured exoskeleton rehabilitation can achieve robot-assisted standing and walking with correct gait patterns within 6-9 months. Individual results vary based on injury severity, patient condition, and training frequency.

Is AiKang covered by medical insurance in China?

AiKang is included in provincial medical insurance coverage in Beijing and Shaanxi provinces. Coverage availability varies by region, and patients should consult their local healthcare providers for specific reimbursement information.
