Comparative Effectiveness of Microprocessor-Controlled and Carbon-Fiber Energy-Storing-and-Returning Prosthetic Feet in Persons with Unilateral Transtibial Amputation: Patient-Reported Outcome Measures

This study aimed to examine differences in patient-reported balance, mobility, socket comfort, and preference between an ESAR foot and an MPA in persons with unilateral transtibial amputation (UTA).
Materials and Methods
Twenty-three participants with UTA enrolled in an institutional review board–approved, randomized crossover protocol with ESAR (Pacifica LP) and microprocessor-ankle configurations (Kinnex, Freedom Innovations) and a 4-week accommodation period. The outcome measures collected included Activities Specific Balance Confidence Scale (ABC), Prosthesis Evaluation Questionnaire–Mobility Subscale (PEQ-MS), and Prosthetic Limb User Survey of Mobility (PLUS-M). Participants were asked to rate Socket Comfort Score (SCS) while ascending and descending a 15° sloped ramp. Finally, ankle-foot preference and aspects liked and disliked about each configuration were recorded.
Results
Significant improvements were seen with the MPA in patient-reported mobility in the community (PEQ-MS, ρ = 0.0465) and socket comfort walking and standing on slopes (SCS, ρ
