[Application and development of intelligent adjustable leg raising system]
Summary
This study introduces an intelligent adjustable leg raising system for quantifiable lower limb rehabilitation. The device effectively improves range of motion and reduces pain, outperforming existing methods.
Area of Science:
- Rehabilitation Engineering
- Biomechanics
- Medical Device Development
Background:
- Lower limb dysfunction requires effective rehabilitation tools.
- Current methods may lack precision in quantifying movement.
- Need for adjustable and accurate assistive devices.
Purpose of the Study:
- To develop an intelligent adjustable leg raising system.
- To quantify and visualize lower limb elevation angle and frequency.
- To assess the system's clinical applicability and effectiveness.
Main Methods:
- Determined adjustable lengths for thighs and cruses.
- Defined flexion angle ranges for hips and knees based on clinical needs.
- Performed force analysis of the hip and knee flexion mechanism.
- Conducted clinical observations for security and effectiveness.
Main Results:
- Developed a compact, adjustable device for hip, knee, and ankle movement.
- Force analysis confirmed design requirements were met.
- Preliminary studies indicated pain relief, improved range of motion, and enhanced rehabilitation.
- Demonstrated superiority over the Brown Ska method (P < 0.05).
Conclusions:
- The intelligent adjustable leg raising system meets clinical requirements.
- Suitable for various patient heights with wide, accurate flexion angle ranges.
- Warrants further improvement and widespread clinical adoption.
