Official title
Automatic Activity-Dependent and Phase-Varying Prosthetic Foot Stiffness Modulation to Improve Balance Control in Individuals With Lower-Limb Amputations in the Real World
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to determine if automatic stiffness modulation improves balance control in ambulatory individuals with below-knee amputations in real-world conditions. The main question this clinical trial will answer is: • Can a user-specific automatic stiffness prosthesis improve balance control compared to user's fixed stiffness prosthesis that was clinically prescribed? Participants will perform free-ranging ambulatory activities outside the laboratory that include nine ambulatory activities of daily living (walking at different speeds, turning, ramp ascent/descent, while carrying a load, and while walking on uneven terrain) while wearing, in random order, 1) a fixed stiffness prosthesis that was clinically prescribed and 2) an automatic stiffness prosthesis that uses an open source ankle configured to implement a user- and activity-specific automatic stiffness modulation control scheme intended to improve balance control.
