Caesar Foot for Below Knee Amputation
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the Caesar foot prosthetic in everyday settings for individuals with below-knee amputations. Participants will use their usual prosthetic foot for one month, then switch to the Caesar foot for two months to assess its impact on daily life and activity levels. Feedback will refine the prosthetic for broader use. Ideal candidates have had a below-knee amputation, are interested in running but lack a running blade, and have used their prosthetic for at least six months. As an unphased trial, this study offers participants the opportunity to contribute to the development of a potentially life-enhancing prosthetic.
Do I need to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinator or your doctor.
What prior data suggests that the Caesar foot is safe for below knee amputation?
Research shows that the Caesar Foot is designed for individuals with a below-knee amputation. Although specific safety data for the Caesar Foot is limited, prosthetic devices like this prioritize user safety and comfort. Studies on prosthetic use highlight the importance of users feeling safe, regardless of their activity level.
The Caesar Foot undergoes testing in real-life situations, with developers closely monitoring its performance and any user issues. This testing aims to ensure the device's safety for everyday use.
While no specific safety issues have been reported for the Caesar Foot, ensuring prosthetic safety remains a top priority during development and testing.12345Why are researchers excited about this trial?
Researchers are excited about the Caesar Foot for below-knee amputations because it promises greater flexibility and adaptability compared to standard prosthetic feet. Unlike traditional options that often provide limited movement, the Caesar Foot is designed to offer enhanced range of motion, potentially improving comfort and functionality for users. This innovation might allow wearers to perform daily activities more naturally and with less effort, which is a significant improvement over conventional prostheses.
What evidence suggests that the Caesar Foot is effective for below knee amputation?
Research has shown that people with lower limb amputations generally prefer energy storing and return (ESAR) prosthetic feet, such as the Caesar Foot, which this trial tests. Studies have found that ESAR feet perform better, and users express greater satisfaction compared to solid ankle cushioned heel (SACH) feet. Users often report that ESAR feet return more energy, making walking feel more natural and less tiring. The Caesar Foot aims to improve mobility and comfort, enhancing quality of life. These benefits are crucial for helping individuals live more active and fulfilling lives after an amputation.678910

Are You a Good Fit for This Trial?
This trial is for adults over 18 with a below-knee amputation, who are at least six months post-amputation and can walk or run well (K3 or K4 ambulator status). They must have a good-fitting prosthetic socket, enough space for the Caesar foot, match one of the Caesar prototypes in size/weight class, and want to run but don't have a running blade.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Baseline
Participants wear their usual prosthetic foot for 1 month to collect baseline data
Experimental Condition
Participants wear the Caesar Foot at home for about 2 months, including running training and acclimation
Post-Experimental Condition
Participants wear their usual prosthetic foot for 1 month after completing the experimental condition
Follow-up
Participants are monitored for safety and effectiveness after treatment, including a final call to discuss any falls and conduct an exit interview
What Are the Treatments Tested in This Trial?
Interventions
- Caesar Foot
Trial Overview
The study tests the Caesar Foot prosthesis by having participants use it daily for two months. It compares their experiences with their usual prosthetic foot before and after this period. The goal is to see how well the Caesar Foot works in everyday life through surveys and performance measures.
