Background:

Developing advanced myoelectric control strategies for upper-limb prosthetics is hindered by the slow, costly process of creating custom sockets for research.
Realistic assessment requires integrating controllers into sockets for users with amputation, which is challenging due to the need for specialized, participant-specific socket fabrication.

Purpose of the Study:

To design and evaluate an inexpensive, user-friendly, 3D-printed Modular-Adjustable transhumeral Prosthetic Socket (MAPS).
To reduce the burden of custom socket fabrication in the research and development pipeline for myoelectric prostheses.

Main Methods:

Developed an open-source, 3D-printed Modular-Adjustable transhumeral Prosthetic Socket (MAPS) in collaboration with prosthetists.
Compared the MAPS system with a participant-specific suction socket through mechanical and functional assessments in a single-participant case study.

Main Results:

The MAPS system demonstrated comparable performance to a participant-specific suction socket in mechanical and functional evaluations.
User feedback indicated similar satisfaction levels between the MAPS and the custom suction socket.

Conclusions:

The Modular-Adjustable transhumeral Prosthetic Socket (MAPS) shows potential as a valuable research tool.
This 3D-printed, open-source socket can accelerate the development and implementation of novel myoelectric control strategies by simplifying comprehensive assessment with amputee participants.
