This study introduces a software environment for designing and simulating neural prosthetics. This virtual prototyping tool aids in developing advanced limb prostheses for patients with paralysis or limb loss.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Rehabilitation Technology

Background:

  • Neural prosthetics aim to restore limb function for paralyzed and amputee patients, but current design methods rely on subjective, time-consuming trial-and-error.
  • Existing approaches are inadequate for complex, anthropomorphic prosthetic limbs and hinder rapid development and clinical application.

Purpose of the Study:

  • To develop a systematic method for designing and evaluating neural prosthetic systems.
  • To introduce a software environment for creating accurate mathematical models and simulating prosthetic limb behavior.
  • To enable virtual prototyping for efficient design and control parameter tuning before physical implementation.

Main Methods:

  • Development of a specialized software environment for constructing and modifying mathematical models of prosthetic limbs.
