💬In plain words
What the trial is, and whether it could suit you
The goal of this proposed project is to gather community-based data from the K2-level Transfemoral Amputee (TFA) population to aid in evidence-based prescription of powered prosthetic knees (i.e., choosing the right device to maximize the benefit for each patient). The investigators intend to use this trial data along with a concurrent study being conducted within the K3-K4 level population to guide the implementation of effective prescriptions towards those that can benefit most from a given device and limit prescription to those who would not see benefit in order to ensure the most judicious use of Department of Defense (DoD) and Veteran's Affairs healthcare dollars. The findings will also be shared with the research community to help drive the design of future devices by identifying what features and functions are most beneficial to which patient populations when the devices are used

📋 Eligibility rules (as published)
Inclusion Criteria:
* Are at least 18 years old
* Transfemoral prosthesis user (limb absence between the knee and hip)

* Have adequate clearance between distal end and ground for necessary knee and foot components
* Current Medicare Functional Classification Level (K-Level) of 2 as determined by the healthcare team
* Socket-Comfort Score: 6 or above to ensure adequate socket fit
* Six months or more experience on a prosthesis
* Body weight between 50kg and 116kg (110lbs - 256lbs)
* Height between 1.2m and 1.95m (47.2in and 76.8in)
* Has a phone to answer periodic study calls
Exclusion Criteria:
* Present injuries to residual limb or contralateral leg affecting functional ability
* Contralateral amputation proximal to MTP (metatarsophalangeal) joint
* Socket issues/changes in the last 6 weeks
* Users with bone-anchored implants
* Health or medical condition, diagnosis, or other cause that would prevent participant from effectively following study protocol, performing required outcome measures, and/or completing the study
Subjects can be excluded at the discretion of the investigator for other unforeseen disqualifying criteria (such as specific cognitive issues, etc.).
If subjects experience a health or medical condition that leaves them immobile for more than 2 weeks, they may be given the option to restart the study condition upon recovery, as long as eligibility criteria is still met, and comparable baseline functionality is demonstrated with outcomes measures.
Using a knee that the subject is unfamiliar with may increase the risk of falling. Therefore, pregnant women should not participate in the study and will be screened by self-disclosure.
