Automated Convenient Wrist Mobilizer for Stretching Exercises

Background: The most prevalent long-term impairments seen due to Stroke or CVA are hemiparesis, which is weakness of the entire left or right side of the body, and hemiplegia, which is total or partial paralysis of one side of the body. These conditions tend to be accompanied by impaired motor coordination, muscle weakness, and impairment of the affected arm's sensory mechanism frequently exhibits spasticity and contractures of the elbow, wrist, and finger muscles. The new design of an automated convenient wrist mobilizer will improve positioning and provide therapeutic intervention in reducing spasticity. Methods: The prototype device was designed which combines a Dynamic Wrist Hand Orthosis with a servomotor, controlled by an ESP32 microcontroller to produce passive wrist flexion and extension through cable driven mechanism. The prototype is intended for patients with mild to moderate wrist spasticity. Result: The current design is a prototype automated convenient wrist mobilizer for stretching exercises and to relieve wrist spasticity without external assistance. It is lightweight, affordable and easy to operate, making it suitable for home-based rehabilitation. Conclusion: In conclusion, the automated convenient wrist mobilizer is a prototype design. It can improve Range of Motion and reduction of spasticity in patient suffering from wrist pain and spasticity.
