Abstract

Purpose

Many studies have shown that rehabilitation robots are crucial for lower limb dysfunction, but application of many robotics have yet to be seen to actual use in China. This study aimed to improve a lower limb rehabilitation robot by details improving and practical design.

Design/methodology/approach

Structures and control system of a lower limb rehabilitation robot are improved in detail, including joint calculations, comfort analysis and feedback logic creation, and prototype experiments on healthy individuals and patients are conducted in a hospital.

Findings

All participating subjects did not experience any problems. The experiment shows detail improving is reasonable, and feasibility of the robot was confirmed, which has potential for overcoming difficulties and problems in practical application.

Research limitations/implications

Therapeutic effects need to be evaluated in the future. Also, more details should be improved continuously based on the actual demand.

Originality/value

The improved robot could assist the lower limb during standing or walking, which has significance for practical application and patients in China.
