An Open-Structure Treadmill Gait Trainer: From Research to Application

Abstract EN

Lower limb rehabilitation robots are designed to enhance gait function in individuals with motor impairments.

Although numerous rehabilitation robots have been developed, only few of these robots have been used in practical health care, particularly in China.

The objective of this study is to construct a lower limb rehabilitation robot and bridge the gap between research and application.

Open structure to facilitate practical application was created for the whole robot.

Three typical movement patterns of a single leg were adopted in designing the exoskeletons, and force models for patient training were established and analyzed under three different conditions, respectively, and then a control system and security strategy were introduced.

After establishing the robot, a preliminary experiment on the actual use of a prototype by patients was conducted to validate the functionality of the robot.

The experiment showed that different patients and stages displayed different performances, and results on the trend variations across patients and across stages confirmed the validity of the robot and suggested that the design may lead to a system that could be successful in the treatment of patients with walking disorders in China.

Furthermore, this study could provide a reference for a similar application design.
