About the study

The investigators do not yet know how a prosthetic socket with adjustable panels affects the performance of people with a lower limb amputation compared to a conventional prosthetic socket. The primary objective of this study is to compare an adjustable and conventional prosthetic socket and use this information to determine the optimal socket that would improve rehabilitation and function in people with lower limb amputation.

What is being tested

• Conventional prosthetic socket (device)
• Adjustable Quatro socket (device)

Sponsor: VA Office of Research and Development · Participants: 40 · Started: Jan 31, 2022
