This project is a 2-arm, parallel, randomized, controlled clinical trial designed to determine if a microprocessor controlled prosthetic footMPF, with greater range of motion and active power, will translate into improved functional performance, ambulatory safety risk of falls and quality of life in trans-tibial amputees TTA who function as limited community ambulators. We will assess these outcomes in 54 veterans with TTA by randomizing participants, in a 11 ratio, into an intervention and a comparison group. Participants in the intervention group will receive an MPF, while the comparison group will continue with their currently prescribed prosthetic foot. All participants will be followed with weekly contact over a 6-month period of time in addition to receiving physical therapy training. All outcome measures will be evaluated three times during the 6 month study period. Once HRPO approval for the project was received in April 2016, recruitment efforts via Partner Prosthetic clinics was undertaken to identify over 700 potentially eligible individuals, 40 of whom were veterans. Similar efforts with the Regional DAV have also been undertaken. Active recruitment began in July 2016 and has yielded 77 individuals responding to recruitment efforts, 76 of whom have been screened for eligibility. Of those, 32 42 percent met eligibility criteria to qualify for evaluation of Medicare Functional Classification Level MFCL using the Amputee Mobility Predictor-Prosthesis AMP-Pro. Five 15.6 percent of those individuals who comprised 7 percent of the total 76 screened met the K-Level 2 classification as a community ambulator and were eligible for randomization to group assignment. Recruitment, enrollmentrandomization, intervention and followup assessments will continue in the coming quarteryear.
