This study is exploring a new way to provide sensation to people who have lost a lower limb, either above or below the knee. It uses stimulating nerve electrodes, which are small devices surgically placed on your remaining nerves. These electrodes deliver tiny electrical currents that aim to create feelings in your missing limb, similar to how your brain used to receive information from your foot and lower leg. The study will measure how much electrical stimulation is needed to create these sensations (Stimulation Thresholds) and how well you can walk and move (Functional Gait Assessment) after the electrodes are implanted. You might also have the option to have recording electrodes placed in your muscles to help develop a robotic prosthetic leg that you can control more intuitively. Adults aged 18 or older with stable amputations and viable nerves are eligible to participate. The current status of the study is unclear, and it plans to enroll 15 participants.

Study design

This is an interventional study with a planned enrollment of 15 participants. It is not specified if it is randomized or blinded.

What's involved

Electrodes will be surgically implanted on one to four nerves. You will describe perceived sensations and wear an instrumented prosthesis for various functional tasks. You may also have recording electrodes implanted in your muscles.

Compensation

Not stated in the trial record.

Follow-up

Stimulation thresholds will be measured at 9 months post-implant, and functional gait assessment will be measured at 1 year post-implant.
