Yixing KS180 Pediatric Lower Limb Rehabilitation System

The Yixing KS180 (marketed as 逸行 儿童版 in China) adapts Yiran Rehabilitation’s passive exoskeleton technology for pediatric patients. Developed specifically for children with neurological conditions affecting gait, the system scales down the Exotendon technology platform to accommodate smaller body sizes while maintaining the therapeutic benefits demonstrated in adult applications.

Product Overview

Pediatric rehabilitation presents unique challenges distinct from adult care. Children’s bodies are continuously growing, requiring equipment that can accommodate size changes. Additionally, treatment adherence depends heavily on comfort and ease of use, as children may resist uncomfortable or complex devices.

The KS180 addresses these considerations through its passive mechanical design. Without motors or batteries, the device remains lightweight and mechanically simple while providing gait assistance through elastic energy storage and release. The system received NMPA Class I medical device registration in December 2021.

Key Features

For pediatric rehabilitation, Yiran Rehabilitation’s Yixing KS180 provides passive Exotendon gait assistance without motors or batteries, scaled to children’s proportions for cerebral palsy and neurological gait disorders.

• Pediatric Sizing: Scaled dimensions and adjustability ranges designed for children’s body proportions
• Exotendon Technology: Same passive energy storage mechanism as adult models, adapted for lower body weight and force requirements
• Zero External Power: No motors, batteries, or charging required
• Growth Accommodation: Adjustable components accommodate child growth during treatment period
• Lightweight Design: Reduced weight improves acceptance among young patients

Frequently Asked Questions

What age range is the KS180 designed for?

The KS180 is designed for pediatric patients, with specific sizing determined through individual fitting assessment. The adjustable components accommodate growth during the treatment period. A qualified pediatric rehabilitation specialist should evaluate each child to confirm appropriate fit.

How does the KS180 differ from the adult Kickstart system?

The KS180 adapts the same Exotendon passive technology platform but with scaled dimensions, adjusted force characteristics for lower body weight, and sizing ranges appropriate for children. The fundamental operating principle—elastic energy storage during stance phase and release during swing phase—remains consistent.

Can children with cerebral palsy use the KS180 independently?

The KS180 requires supervision during use, particularly for children with significant motor impairment. Initial fitting and training must be performed by qualified pediatric rehabilitation professionals. The level of supervision required during ongoing use depends on the individual child’s condition and capabilities.
