Current transfemoral prosthetic sockets are problematic as they
restrict function, lack comfort, and cause residual limb problems. Development of
a subischial socket with lower proximal trim lines is an appealing way to address
this problem and may contribute to improving quality of life of persons with
transfemoral amputation.
The purpose of this study was to illustrate
the use of a new subischial socket in two subjects. STUDY DESIGN: Case series.
METHODS: Two unilateral transfemoral prosthesis users participated in preliminary
socket evaluations comparing functional performance of the new subischial socket
to ischial containment sockets. Testing included gait analysis, socket comfort
score, and performance-based clinical outcome measures (Rapid-Sit-To-Stand,
Four-Square-Step-Test, and Agility T-Test). RESULTS: For both subjects, comfort
was better in the subischial socket, while gait and clinical outcomes were
generally comparable between sockets. CONCLUSION:
While these evaluations are
promising regarding the ability to function in this new socket design, more
definitive evaluation is needed. Clinical relevance Using gait analysis, socket
comfort score and performance-based outcome measures, use of the Northwestern
University Flexible Subischial Vaccum Socket was evaluated in two transfemoral
prosthesis users. Socket comfort improved for both subjects with comparable
function compared to ischial containment sockets.
