ObjectiveTo compare energy cost of walking (ECW) and prosthesis-related perceived mobility with the Marlo Anatomical Socket (MAS®) and the Ischial Containment (IC) Socket.MethodTransfemoral (TF) amputees were enrolled in the study. ECW tests were conducted inside, in a hallway with a regular floor surface. Subjects had to walk back and forth on a 61 m linear course at their own self-selected speed. Metabolic and heart rate data were collected during the walking test using a portable gas analyzer. All measurements were made at steady state (SS). The tests were performed first using the IC socket and then after 30 days of MAS® use; the last test was carried out after 60 days of MAS® use. The amputees were also administered the Prosthetic Evaluation Questionnaire Mobility Section (PEQ MS) at the first and the last test to assess perceived potential for mobility using the prosthesis.ResultsSeven long-term prosthesis users were analyzed. Their mean age was 33.9 ± 9.3 years; all were employed, active, and used IC sockets. At the third walking test, the ECW with the MAS® was significantly lower than that with the IC socket (p = .016). PEQ MS data also improved significantly at the last evaluation (p < .018).ConclusionResults suggest that using the MAS®, lowering the ECW and improving PEQ MS, could be a valid prosthesis design for active TF amputees compared to their usual IC socket.
