Summary

Developing advanced prosthetic control interfaces using cineplasties and extended physiological proprioception (EPP) offers improved sensory feedback. This surgical technique allows muscles to directly control prosthetic components, enhancing user experience and functionality in upper-limb prostheses.

Area of Science:

  • Biomedical Engineering
  • Rehabilitation Engineering
  • Prosthetics and Orthotics

Background:

  • Improving upper-limb prosthesis function requires better control interfaces with sensory feedback.
  • Cineplasties, surgical procedures externalizing muscle force and excursion, offer potential for superior prosthetic control.
  • Extended physiological proprioception (EPP) aims to provide inherent physiological sensory feedback through cineplasties.

Purpose of the Study:

  • To explore the feasibility of using cineplasties with EPP controllers for advanced prosthetic control.
  • To enable meaningful independent multifinger control of hand prostheses via miniature forearm tunnel cineplasties.
  • To augment control of multifunctional total arm prostheses at higher amputation levels using pectoral or deltoid cineplasties.

Main Methods:

  • Quantified control capabilities of individuals with biceps muscle tunnel cineplasties using pursuit tracking experiments.
  • Developed a proof-of-concept EPP electric hand prosthesis for a subject with forearm tendon exteriorization cineplasties.
  • Utilized cineplastized muscles as a novel control source for prosthetic devices.

Main Results:

  • Tracking studies demonstrated the efficacy of control by cineplastized muscles numerically.
  • The developed EPP electric hand prosthesis showed successful proof-of-concept.
  • Cineplasties enable direct physiological sensory feedback integration with prosthetic components.

Conclusions:

  • Cineplasties combined with EPP controllers represent a promising approach for advanced upper-limb prosthesis control.
  • This method enhances functional control and sensory feedback for prosthesis users.
  • Further research into cineplasties can lead to more intuitive and effective prosthetic devices.
