Summary
Intelligent artificial knee joints significantly improve walking stability and gait for amputees compared to hydraulic ones. Image processing aids personalized rehabilitation by analyzing gait characteristics objectively.
Area of Science:
- Biomedical Engineering
- Rehabilitation Science
- Computer Vision
Background:
- Advancements in assistive devices mature artificial knee joint applications for amputee rehabilitation.
- Individual differences in residual limb length and muscle strength limit current artificial knee joint adaptability for personalized patient recovery.
Purpose of the Study:
- Analyze the impact of different artificial knee joints on the walking function of unilateral thigh amputees.
- Enhance artificial knee joint performance and patient rehabilitation outcomes through gait analysis.
Main Methods:
- Utilized image processing technology with video and computer hardware for gait analysis.
- Recognized and tracked patient landmarks to analyze gait patterns in amputees with different prostheses.
- Developed personalized treatment plans based on gait analysis and psychological reactions.
Main Results:
- Hydraulic single-axis prosthetic joints showed 79% walking stability and low gait elegance.
- Intelligent artificial joints demonstrated 96% walking stability with generally good gait elegance.
Conclusions:
- Image processing provides objective data for understanding patient gait and rehabilitation progress.
- This technology supports personalized rehabilitation plans for amputees using various artificial knee joints.
