Evaluating Stumble Recovery Functions of Prosthetic Knees

Evaluating Stumble Recovery Functions of Prosthetic Knees

The study aims to conduct a formative evaluation, along with verification, validation, and comparative analysis of the stumble recovery function in prosthetic devices by collecting relevant clinical data. The study will involve participants who are current users of lower-limb prosthetics. Utilizing a robust study design, data will be gathered in both controlled setting and real-world to thoroughly assess the performance, safety, and user satisfaction of the function. The scientific value of this research lies in its potential to enhance prosthetic technology, support evidence-based clinical practices, and ultimately improve the quality of life for users by reducing fall risks and increasing mobility confidence.
