NCT05230004

Brief Summary

An immediate fit adjustable prosthetic system is being investigated for children. The age range being recruited is from 3 years up to 18 years old. Phase I of this study will involve developing a final prototype by conducting in-lab testing on children with limb loss. Phase II will involve a two month home trial to further evaluate the comfort and usability of the socket. Outcome measures include a PEQ-based questionnaire, socket pressure measures and gait analysis.

Phase II

EXPERIMENTAL

Phase II involves a two month home trial to determine the comfort and utility of an adjustable prosthetic system for children. Children will be fit at several different locations by their prosthetist with the adjustable socket. They will complete several questionnaires on their current device, as well as have internal socket pressures and a gait analysis completed. They will return one month later to complete the same outcome measures on their conventional device. They will also be given activity monitors to track their activity through the duration of the project.

Device: iFIT prosthesis

Phase I

EXPERIMENTAL

Phase I involves developing a final design for an adjustable, immediate fit prosthesis. We will recruit 5-10 participants age 3-12 to complete in-lab testing and evaluation of several designs. This testing will lead to the final product design to be tested in Phase II.

Device: iFIT prosthesis

Interventions

An adjustable modular prosthesis that can be fit in a single session. Fully adjustable by wearer.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

You may not qualify if:

  • open skin lesions
  • excessive pain in the residual limb (phantom pain, residual limb pain, or neuroma)
  • neurological disorders (e.g., stroke, severe polyneuropathy) causing weakness in the contralateral leg or marked gait impairment
