NCT05989243 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 40

Last updated 2026-04-23

No results posted yet for this study

Summary

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.

Conditions

  • Transtibial Amputation
  • Transfemoral Amputation

Interventions

DEVICE

Conventional prosthetic socket

Participants will use their own conventional rigid socket and will be asked to walk on a force-measuring treadmill on level ground at 0.75, 1.0, 1.25, and 1.5 m/s for \~60 sec per speed. They will also be asked to evaluate this socket using a questionnaire.

DEVICE

Adjustable Quatro socket

Participants will use an adjustable Quatro socket and will be asked to walk on a force-measuring treadmill on level ground at 0.75, 1.0, 1.25, and 1.5 m/s for \~60 sec per speed. They will also be asked to evaluate this socket using a questionnaire.
