Restoration of Normative Postural Control

Description

The objective of this proposal is to investigate the effects of training to use direct electromyographic (dEMG) control of a powered prosthetic ankle on transtibial amputees'. The aimed questions to answer: 1. whether dEMG control will improve balance and postural stability of amputees, 2. whether dEMG control will lead to more natural neuromuscular control and coordination, 3) whether dEMG control will reduce cognitive processes. Participants will go through PT guided training on using dEMG controlled prosthetic ankles and are evaluated for their capability on functional tasks. The results will be compared with a comparison group, which goes through the same training but with their everyday passive prostheses on balance capability, neuromuscular coordination, and cognitive load during locomotion.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * 18 years or older;
  • * unilateral bower limb amputee

  • * Amputation occurred over 2 years ago
  • * At least 1 year of experience using their prosthetic leg
  • * Has used the current socket for at least 6 months without a significant skin issue or major modification
  • * Are willing to come to NC State University's Centennial Campus to participate in research and be photographed while doing research activities
  • * Have a very short residual shank (the length of the residual limb is ≤15% of the length of intact limb)
  • * Cannot perform functional ambulation in the community on a daily basis without assistive devices
  • * Cognitive or visual impairment that affects the participant's ability to provide informed consent or to follow simple instructions during the experiments
  • * Congenital amputees
  • * Amputees who use powered prosthetic ankles
  • * Weight more than 300lbs
  • * Pregnant Person
  • * Allergic to latex, which is often contained in medical tapes.
