Assessment of a Microprocessor Ankle for Low Mobility Individuals

Synchro Motion LLC·interventional·Posted Jul 21, 2023·Updated Jul 1, 2025

In Brief

A clinical study evaluating DSR Ankle and Predicate Ankle for Amputation and Limb Deficiencies. Completed, enrolled 5 participants across 1 site.

Detailed Summary

This research is being done to conduct a preliminary investigation into a new prosthetic microprocessor controlled (MPC) ankle, called the Damping, Stiffness, and Repositioning (DSR) ankle. The DSR ankle is a new design to support a person while they walk on both even and uneven ground, as well as with bending the ankle for safe foot clearance while a person takes a step. In particular, in this study we are interested in seeing how this type of new device may benefit people who are rated as a K2-level ambulator.
