Brief description of study
This study aims to develop an adjustable, immediate fit prosthetic device for children age 3- 18 which will accommodate growth. We are looking for children with lower limb amputation- above knee, below knee and symes amputations.
All testing will be done within the PM&R Gait Lab located at 1800 Lombard St, Philadelphia, PA. Participants will be fit with an adjustable lower limb prosthetic socket to obtain feedback and evaluate the design of the adjustable prosthetic.
For Phase II, we will conduct a two month home trial to fully evaluate the adjustable socket.
Detailed description of study
The parents of the participant will send in measures and pictures of the child's limb in order to create a prototype prior to the first visit. The adjustable socket will be fit on the child in the gait lab and the child will be asked to ambulate. The child and parent will give their impressions and feedback on the design.
For Phase II, children will wear the prosthesis for a two month time period. They will fill out an evaluation of their current socket, and have internal pressure measurements taken. When they return they will complete an evaluation on the adjustable socket and have pressure measurements taken. We will also conduct a gait analysis of the participant in their socket and the adjustable socket. We may also ask the child to complete a gait analysis which involves walking several times back and forth in the gait lab.
Additional InformationParticipants will be able to keep the socket after the trial if they wish.
