Area of Science:

Biomedical Engineering
Rehabilitation Technology
Prosthetics and Orthotics

Background:

Prosthetic alignment is critical for successful patient rehabilitation after amputation.
Accurate and repeatable alignment adjustments are essential for optimal prosthesis function.
Current methods for recording alignment data can be cumbersome and lack precision.

Purpose of the Study:

To introduce a novel digital device for reading and recording prosthetic alignment data.
To enable precise replication of prosthesis adjustments for future use.
To facilitate the examination of alignment changes and their impact on patient posture.

Main Methods:

A newly invented digital device with seven components was utilized.
The device records alignment data at anterior/posterior and medial/lateral positions.
Data were collected from five patients undergoing prosthetic rehabilitation.

Main Results:

The digital device demonstrated a high level of confidence in recording alignment data.
Replication of prosthesis adjustments was found to be accurate and reliable.
The device facilitates both self-adjustment by patients and professional adjustment by prosthetists.

Conclusions:

The developed digital device offers a significant advancement in prosthetic alignment procedures.
It empowers patients and prosthetists with a tool for precise adjustments and analysis.
This technology has the potential to improve patient outcomes and reduce complications associated with malalignment.
