Area of Science:

Biomedical Engineering
Rehabilitation Technology
Prosthetics Research

Background:

The Defense Advanced Research Projects Agency (DARPA) initiated the Revolutionizing Prosthetics program.
A Virtual Integration Environment (VIE) was developed as a common platform for prosthetic limb research and development.
Clinical needs identified during VIE development highlighted the necessity for advanced simulation and data capture capabilities.

Purpose of the Study:

To introduce a novel feature within the VIE for creating animations of activities of daily living (ADLs).
To enable simultaneous capture of real-time surface electromyography (EMG) data corresponding to ADLs.
To support research efforts aimed at reducing phantom limb pain (PLP) in upper extremity amputees.

Main Methods:

Development of an animation and EMG data capture feature within the existing VIE platform.
Utilizing the VIE by the Walter Reed Military Amputee Research Program (MARP).
Investigating methods to reduce phantom limb pain (PLP) through advanced prosthetic development and testing.

Main Results:

The VIE now facilitates the creation of realistic ADL animations.
Real-time surface EMG data can be captured concurrently with animations.
This integrated approach provides a powerful tool for prosthetic research and clinical application.

Conclusions:

The enhanced VIE offers a significant advancement for prosthetic research and clinical applications.
The new feature aids in understanding the relationship between limb movement and neural signals.
This technology has direct applications in improving the quality of life for amputees, particularly in managing phantom limb pain.
