Study Summary

This trial will collect data to determine how different ankle-foot prostheses affect gait. Subjects will wear sensors and use prostheses while walking on level-ground, treadmill, and stairs. Data will be collected and prosthesis controllers adjusted for best gait.

Who is the study for?
This trial is for individuals aged 18-65 with a single below-knee (transtibial) amputation who are fairly to very active, as indicated by a K3 or K4 Medicare mobility rating. It's not suitable for those under 18 or over 65, or less active individuals rated below K3.Check my eligibility
What is being tested?
The study tests different prosthetic foot-ankle mechanisms: MIT's Variable Stiffness and Equilibrium Angle Prostheses, the Sliding Beam Passive Prosthesis, Ossur's Pro-flex XC, and Blatchford's Elan Variable-Dampening Prosthesis. Participants will use these while walking on various surfaces and their gait will be analyzed using sensors and motion capture.See study design
What are the potential side effects?
While there may not be traditional 'side effects' like in drug trials, participants might experience discomfort adjusting to different prosthetics. There could also be muscle strain or skin irritation at the site of prosthesis attachment.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are adolescents within the age range of this investigation?

"The age restriction for this trial is 18 years and over, with an upper limit of 65."

Answered by AI

Are there any vacancies for this clinical experiment currently available?

"Clinicaltrials.gov does not list this clinical trial as actively recruiting. The first posting was on July 28th 2023, and the last edit occurred 10 days later on July 19th 2023. Nonetheless, there are presently multiple other medical studies that need new patients."

Answered by AI

What are the main goals of this clinical research?

"This trial will monitor the primary outcome of user preference for stair ascent and descent over a period of 8 hours, spread out across two separate sessions. Secondary outcomes include evaluations on sloped walking gait patterns utilizing Vicon motion capture technology, ground reaction forces during ambulation using Bertec force plates in Newtons, as well as assessing gait symmetry with regards to stair negotiation."

Answered by AI

Who is eligible to take part in this research project?

"To qualify for the trial, subjects must be between 18 and 65 with a transtibial amputation. The team is currently seeking out 10 potential participants."
