Summary
This study presents a new hand prosthesis operated by wrist movement, offering improved function and appearance. Developed with a lifelike silicone glove, it benefits patients with partial hand loss or congenital absence.
Area of Science:
- Biomedical Engineering
- Prosthetics and Orthotics
- Rehabilitation Medicine
Background:
- Hand amputations and congenital absences significantly impact patient quality of life.
- Existing prostheses often have limitations in function and cosmetic appearance.
- Innovative solutions are needed to improve outcomes for individuals with hand differences.
Purpose of the Study:
- To describe a novel hand prosthesis design.
- To introduce a wrist-actuated grip mechanism for hand prostheses.
- To evaluate the functional and cosmetic outcomes of the new prosthesis.
Main Methods:
- Development of a prosthesis utilizing wrist flexion/extension for grip control.
- Creation of a lifelike, flexible glove covering using a silicone polymer.
- Clinical fitting and evaluation of the prosthesis in thirteen patients.
Main Results:
- The prosthesis demonstrated effective grip operation through wrist movements.
- The silicone covering provided a lifelike and flexible glove.
- Positive functional and cosmetic results were observed in the thirteen fitted patients.
Conclusions:
- The novel wrist-actuated hand prosthesis offers a viable solution for patients with hand loss or absence.
- The use of silicone polymers enhances the cosmetic and functional aspects of the prosthesis.
- This innovative prosthesis can significantly improve patient function and cosmesis.
