Area of Science:

Biomedical Engineering
Rehabilitation Medicine
Robotics

Background:

Burn injuries frequently cause severe hand complications, including joint contractures, nerve damage, and amputation.
Hypertrophic scarring post-burns significantly impairs hand function and can interfere with electromyography (EMG) sensing for prosthetics.

Purpose of the Study:

To evaluate the clinical efficacy of a customized 3D-printed robotic finger prosthesis for a burn-induced amputee.
To assess improvements in hand function, grip strength, and daily task performance using motion-mimicking prosthetic technology.

Main Methods:

A case study involving a 24-year-old male with left second finger amputation due to electrical burns.
Utilized a customized three-dimensional (3D) printed robotic finger prosthesis with a finger motion-capturing device.
Compared pre- and post-prosthesis adoption functional outcomes, including grip strength and dexterity.

Main Results:

The patient demonstrated significant improvements in grip strength and performance of daily tasks after adopting the personalized robotic finger prosthesis.
The motion-mimicking prosthesis exhibited reduced latency compared to EMG-based systems, overcoming scar-related sensing issues.
The customized 3D-printed prosthesis proved to be an affordable and effective solution.

Conclusions:

Customized 3D-printed robotic finger prostheses are a viable and effective solution for restoring hand function in burn amputees.
Motion-mimicking technology offers advantages in reduced latency and improved dexterity, particularly when EMG sensing is compromised by scarring.
This innovative approach holds potential for wider application and improved quality of life for individuals with burn-induced upper limb loss.
