Wireless Active Finger Rehabilitation Method Using Three-Axis Electromagnetic Manipulation

This paper presents a wireless active finger rehabilitation method controlled magnetic forces within a three-axis coil system. The three-axis coils enhanced degree of freedom in hand positioning. The developed system includes three magnets for controlling one finger within the coil, thus, providing external force to the finger without the use of a complex mechanical structure. The proposed method is simple in configuration and operates wirelessly by magnetic interaction. The system generates three magnetic forces for flexion and extension of the finger. The proposed method can be used regardless of the position of the hand in the system. The combined influence of the three magnetic forces used to generate flexion and extension of the finger was verified through experimental analysis.
