The goal of a recent survey I conducted regarding transfemoral interface designs was to understand the trends related to practitioner experience and transfemoral interfaces. There were 233 respondents with a 100 percent completion rate and 46 additional qualitative comments. The largest group (29 percent) had 26 years or more of experience, followed by those with 0-5 years of experience at 18 percent. When rating their expertise, the largest group was “expert” at 41 percent, followed by “intermediate” at 33 percent and “specialist” at 13 percent. The distribution of confidence and expertise indicated a higher degree of confidence and self-efficacy with transfemoral interfaces and fitting.
