New treatment option for Transfemoral Amputation
Official title A Biomechanical Evaluation of the Ossur Power Knee in Persons With Transfemoral Amputation
ClinicalTrials.gov ID: NCT06218238
What this study is testing
- What it's testing
- Microprocessor-controlled knees (MPKs) do not typically utilize motors to power joint rotation, but they automatically adjust resistance or damping in the joint to improve swing- and/or stance-phase control as appropriate for the prosthesis user during gait. The Ossur Power Knee is the only commercially-available MPK that uses a motor to provide active power generation during walking and other activities.
