Trial Outcomes & Findings for Optimizing Prosthetic and Bicycle Fit for Veterans With Transtibial Amputations (NCT NCT03828331)
NCT ID: NCT03828331
Last Updated: 2024-12-10
Results Overview
The investigators calculated crank power output (W/kg) from the product of pedal torque and velocity and normalized this to participant body mass while participants rode at 1.5 W/kg using different prosthetic and bicycle configurations (pylon length, crank arm length, and pedal attachment position).

Participants With Transtibial Amputation
The investigators will recruit participants with unilateral transtibial amputations who are at or above a K3 Medicare functional classification level (MFCL), and 18-55 years old. A K3 MFCL means that a person has the ability or potential for ambulation with variable cadence. A person at K3 MFCL is a typical community ambulator who has the ability to traverse most environmental barriers and may have vocational, therapeutic or exercise activity that demands prosthetic use beyond simple locomotion.
Prosthetic/Bicycle Configuration: The investigators will measure the biomechanics (motion, forces, and muscle activity) and metabolic rates while subjects ride using an initial bike fit and three taller pylon lengths (PL) for the affected leg (AL) in increments of 6.8 mm using a pedal attachment position (PAP) beneath the prosthetic forefoot. Then, using the optimal (most efficient) PL, the investigators will measure the biomechanics and metabolic rates while subjects ride using three shorter crank arm lengths (CALs) for the AL in decrements of 6.8 mm using a PAP beneath the prosthetic forefoot. On Day 2, the investigators will repeat the protocol of Day 1, but have riders use a PAP beneath the pylon for their AL.

PRIMARY outcome
Timeframe: Data were collected over 2 days per subjectThe investigators measured net metabolic power (W/kg) using an equation that considers rates of oxygen consumption and carbon dioxide production and normalized this to participant body mass while participants rode at 1.5 W/kg using different prosthetic and bicycle configurations (pylon length, crank arm length, and pedal attachment position).

PRIMARY outcome
Timeframe: Data were collected over 2 days per subjectThe investigators measured comfort with a questionnaire that has a range of 0-10 that indicates terrible to excellent, respectively, after participants rode at 1.5 W/kg using different prosthetic and bicycle configurations (pylon length, crank arm length, and pedal attachment position).
