Prosthetics

Background:

The prosthetic socket is crucial for lower-limb prostheses, connecting the residual limb to the artificial limb.
Poor socket fit and discomfort are major reasons amputees abandon prostheses.
Key factors affecting socket performance include interfacial stress, residual limb volume fluctuation, and temperature.

Purpose of the Study:

To review existing sensing and actuation solutions for enhancing prosthetic socket performance.
To discuss technologies for monitoring and actively adjusting the residual limb-socket interface.
To outline the development of next-generation 'smart socket' prostheses.

Main Methods:

Literature review of sensing technologies for socket interface monitoring.
Review of actuation methods for active socket interface modification.
Analysis of sensor and actuator integration for smart socket development.

Main Results:

Various sensors can monitor residual limb-socket interface parameters.
Actuation methods offer potential for active socket adjustment.
Integration of sensing and actuation is key to smart socket realization.

Conclusions:

Smart sockets promise to improve amputee comfort and prosthesis function.
Sensing and actuation technologies are vital for self-adjusting prosthetic sockets.
Continued development will lead to optimized prosthetic fit, function, and performance.
