ClinConnect Summary

This clinical trial is looking at how the biomechanics, or the way forces work on the body, affect endurance runners who have had a leg amputated below the knee (called a transtibial amputation). The researchers want to understand how using special running blades made of carbon can help these athletes perform better while also considering their comfort and safety. The study will explore how these blades are adjusted for individual runners to ensure they can run efficiently and reduce the risk of injury, especially when there are differences between their healthy and amputated legs.

To participate in this trial, you must be between 18 and 75 years old, weigh less than 110 kg, and have been running with a sports blade for at least three months. You should also have signed a consent form and be part of a social security scheme. However, if your amputation was due to diabetes complications, you have certain chronic health issues, or if you are pregnant or breastfeeding, you won't be eligible. If you join the study, you can expect to contribute to important research that could improve the experience of other runners with similar amputations and help shape better running aids in the future.
