Slope Adaptive Foot for Amputation
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new prosthetic foot called the Fillauer Slope Adaptive Foot (SAF). It aims to help veterans with below-knee amputations walk more effectively on sloped or uneven surfaces, enhancing mobility and reducing fall risks. Participants will try both the SAF and a typical hydraulic foot to determine which works better for them. The trial seeks U.S. military veterans with a below-knee amputation who have used a prosthesis comfortably for at least a year and can walk in the community without limits. As an unphased trial, this study offers veterans the chance to explore innovative prosthetic technology that could enhance their daily mobility.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your healthcare provider.
What prior data suggests that the Slope Adaptive Foot is safe for veterans with below-knee amputations?
Research has shown that slope-adaptive prosthetic feet, such as the Fillauer Slope Adaptive Foot (SAF), can improve walking on sloped surfaces. Studies have found that these feet may enhance safety by increasing the gap between the toe and the ground, helping to prevent trips and falls. This suggests that the SAF is a suitable option for individuals with below-knee amputations. Additionally, initial testing with Veterans received positive feedback, indicating possible improvements in daily activities and confidence.
Although specific safety details for the SAF are not provided, its design focuses on enhancing movement and safety, which are promising signs of its suitability. It is important to consult healthcare providers to understand the potential risks and benefits before joining a trial.12345Why are researchers excited about this trial?
The Fillauer Slope Adaptive Foot (SAF) is unique because it adapts to uneven terrain, providing a more natural walking experience for amputees. Unlike standard prosthetic feet, which may struggle on slopes or uneven surfaces, the SAF adjusts its angle to match the ground, enhancing stability and comfort. Researchers are excited about this innovation as it could significantly improve mobility and quality of life for users by allowing them to navigate a wider range of environments with ease.
What evidence suggests that the Slope Adaptive Foot is effective for improving mobility in veterans with below-knee amputations?
Research shows that the Fillauer Slope Adaptive Foot (SAF) can help people with below-knee amputations move better. Studies have found that the SAF adjusts to sloped and uneven ground, making walking smoother and more stable. This feature may lower the risk of falls and boost confidence in walking. Early results suggest that SAF users have better balance and gain more energy with each step, reducing the effort needed for walking. In this trial, participants will experience both the SAF and the SLX in a cross-over design to compare their effects. Overall, these benefits might lead to greater involvement in everyday activities and hobbies.16789

Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Cross-over Randomized Controlled Trial
Participants undergo a cross-over RCT with the Slope Adaptive Foot (SAF) and typical hydraulic foot (SLX), each for a 4-week take-home period, separated by a 4-week washout period.
Observational Study
Participants use their preferred prosthetic foot for a one-year observational study, with quarterly assessments.
Follow-up
Participants are monitored for safety and effectiveness after the observational study.
What Are the Treatments Tested in This Trial?
Interventions
- Fillauer Slope Adaptive Foot
Trial Overview
The study tests a new Slope Adaptive Foot (SAF) against a typical hydraulic foot, Fillauer Motion Foot SLX, in a cross-over randomized controlled trial. It aims to see if SAF improves participation in daily activities and reduces fall risks for veterans.

Experimental Treatment
Participants in this arm will start the cross-over randomized controlled trial with the SLX. After a four-week take-home period with the SLX, participants will return to their usual prosthetic foot for a four-week washout period. They will then be fit with the SAF for a four-week take-home period.
