Investigation of Motorized Lower-limb Prostheses
{ "Investigation of Motorized Lower-limb Prostheses", "This study is looking into whether a motorized prosthesis can help people with lower-limb amputations move around better. Researchers want to see if using the motorized prosthesis improves walking speed, balance, control, or how efficiently you move during everyday activities, compared to your usual prosthesis. You would try out different activities like walking on inclines, stairs, and uneven ground, both with your own prosthesis and with the experimental motorized prosthesis. The study will compare how you move in these different situations. The goal is to understand if this new device can improve your mobility and what challenges might come up when using it. We are looking for 20 participants, aged 18 to 85, who can walk at least 30 feet.", "design": "This is an interventional study involving 20 participants. You will try different conditions of the motorized prosthesis and your own prosthesis.", "commitments": "You will perform various ambulation activities over four assessment days, walking for up to 40 minutes each day.", "compensation": "Not stated in the trial record.", "follow_up": "Assessments will be taken on Day 1, Day 2, Day 3, and Day 4, which are the timeframes for the primary endpoints.", }

What this trial measures
- Joint positionAssessment will be taken on Day 1 (Intervention 1), Day 2 (Intervention 2 - condition 1), Day 3 (Intervention 2 - condition 2), and Day 4 (Intervention 2 - condition 3)
Motion capture measurements will be taken to calculate joint position (degrees) of the ankle, knee, hip, and torso. Participant measurements will be averaged per condition to generate a participant average. Participant averages will be pooled to determine an average per condition.
- Joint VelocityAssessment will be taken on Day 1 (Intervention 1), Day 2 (Intervention 2 - condition 1), Day 3 (Intervention 2 - condition 2), and Day 4 (Intervention 2 - condition 3)
Motion capture will be used to record joint velocity (deg/s) of the ankle, knee, hip, and torso. Participant measurements will be averaged per condition to generate a participant average. Participant averages will be pooled to determine an average per condition.
- Ground reaction forceAssessment will be taken on Day 1 (Intervention 1), Day 2 (Intervention 2 - condition 1), Day 3 (Intervention 2 - condition 2), and Day 4 (Intervention 2 - condition 3)
The force a participant exerts on the ground (Newtons) will be measured using a force plate. Participant measurements will be averaged per condition to generate a participant average. Participant averages will be pooled to determine an average per condition.
- Muscle Electric PotentialAssessment will be taken on Day 1 (Intervention 1), Day 2 (Intervention 2 - condition 1), Day 3 (Intervention 2 - condition 2), and Day 4 (Intervention 2 - condition 3)
Muscle electric potential will be measured using skin mounted electrodes (surface electromyography) and reported in volts. Participant measurements will be averaged per condition to generate a participant average. Participant averages will be pooled to determine an average per condition.
- Gas uptake and exchangeAssessment will be taken on Day 1 (Intervention 1), Day 2 (Intervention 2 - condition 1), Day 3 (Intervention 2 - condition 2), and Day 4 (Intervention 2 - condition 3)
Oxygen consumption and CO2 production will be measured in L/s. Participant measurements will be averaged per condition to generate a participant average. Participant averages will be pooled to determine an average per condition.
