The goal of this project is a useful clinical instrument for diagnosis and treatment of residual limb volume fluctuation in individuals who use prosthetic limbs. One hypothesis to be tested is that the instrument effectively measures short and long term volume fluctuations in individuals with trans-tibial amputation. Another hypothesis to be tested is that when subjects add a sock or insert to the prosthesis residual limb volume decreases, and when they remove the sock or insert residual limb volume increases.

Groups/Cohorts Assigned Interventions
Lower-limb amputee
Subjects with at least one lower limb amputated at the trans-tibial level
Other: Monitored for limb volume
Subjects are monitored for limb volume change using bioimpedance analysis


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population

people with lower limb amputation that are ambulatory


Inclusion Criteria:

  • trans-tibial amputees who have a regular prosthetist and who wear the prosthesis at least five hours per day.

Exclusion Criteria:

  • Inability to ambulate continuously with a prosthesis (with or without the use of an assistive device such as a cane or walker) for 10 minutes indoors on a level walkway. 2. Inability to shift from horizontal to vertical posture in 30 seconds.
