Design and Development of Assisted Device for Wrist Rehabilitation
Project Area of Specialization RoboticsProject SummaryRobot-augmented therapy is a clinically verified path forward to improve rehabilitation outcomes for neuromuscular conditions. In some muscular and neurological disorder, patients are unable to move their wrist. They maybe affected by joint stiffness or pain etc. that resist the movement. Due to the neuromuscular disorder like ulnar neuropathy of wrist, people suffer from lack of working of wrist which restrict the degree of freedom. Therefore, an assistive device is needed which helps in recovery of disorder that enables the patients to move the wrist.
Project ObjectivesProject’s aim is to develop assistive device prototype which will perform 3 DOF movement of the wrist at certain degrees. Furthermore, speed of device will be adjustable and time of rehab exercise will be in user’s control.
Project Implementation MethodThe project implementation method includes;
1.Selection of electronic components
a) Motors and drive circuits
b) Controller
2.Design of mechanical assembly
3.Design of electronic assembly
4.Fabrication of electro-mechanical assembly
5.Testing
Benefits of the Project1. This assistive device will help in recovery of disorder that enables the patients to move the wrist.
2. Treatment of ulnar neuropathy of wrist.
3. Low cost and portable.
4. Indigeneous development.
Technical Details of Final DeliverableIn this project, assisted device prototype is fabricated for the rehabilitation of 3 DOF wrist movements. Control speed along with time will make it easy for the patients to move their wrist according to their requirements and controllability. The assistive device consists of mechanical assembly and circuitry. The mechanical assembly fabricated through hard acrylic material with appropiate dimensions required for palcement of wrist and arm. The 3 DOF movements were controlled through motors and arduino microcontroller.The device design is provided by graphical user interface (GUI) for mode selection and parameter adjustment.
