Classification and Application Status of Lower Limb Exoskeleton Rehabilitation Robots

Journal of Biomedical Engineering, 2024 · DOI: 10.7507/1001-5515.202211055 · Published: August 1, 2024

Simple Explanation

Lower limb exoskeleton rehabilitation robots help people with walking and movement disorders regain or improve their abilities. Different patients need different functions based on their specific conditions. The article categorizes existing lower limb exoskeleton rehabilitation robots by their main functions and the needs of patients with various lower limb movement disorders, summarizing the correlations between the functions of devices and diseases. The aim is to provide a reference for designing new, more targeted lower limb exoskeleton rehabilitation robots.

Key Findings

1
Lower limb exoskeleton rehabilitation robots can be categorized into three main types: enhanced assistance, motion compensation, and gait correction.
2
Enhanced assistance exoskeletons are designed for patients with muscle weakness to provide extra power and support.
3
Motion compensation exoskeletons are for patients with severe spinal cord injuries, helping them restore some motor function.

Research Summary

This paper categorizes lower limb exoskeleton rehabilitation robots into three types based on their function and application: enhanced assistance, motion compensation, and gait correction. Enhanced assistance types focus on providing extra power for individuals with muscle weakness. Motion compensation types aim to restore movement for those with complete or partial loss of motor abilities.

Practical Implications

Targeted Design

Understanding the different types of exoskeletons and their specific functions allows for the development of more targeted and effective rehabilitation devices.

Clinical Application

The categorization helps clinicians choose the most appropriate exoskeleton for patients with specific lower limb functional impairments.

Future Development

Highlighting the limitations of current devices guides future research and development efforts to improve the effectiveness, safety, and applicability of lower limb exoskeletons.

Study Limitations

1
Current devices often lack comprehensive evaluation metrics for assistive performance.
2
Motion compensation devices have limited range of motion and slow walking speeds.
3
Gait correction devices are often confined to planar movements, limiting their ability to simulate natural walking.
