AmpuEase – Transtibial Amputee Study

A poorly fitting prosthetic socket can greatly affect the daily lives of amputees – leading to 25% to 50% of amputees eventually abandoning their prosthesis.

Amputee socket design

The AmpuEase research team is on a mission to solve the everyday challenges transtibial amputees face with their prosthetic sockets. By combining detailed surveys, group discussions, and cutting-edge medical imaging, the team will uncover the root causes of discomfort and fit issues. Participants’ insights and scans will drive the design of an adjustable, custom-fit socket, with prototypes tested by real users to ensure optimal comfort and function.

Who can participate?

Below-knee amputees seeking to improve comfort and mobility, for themselves and others, are invited to get involved.

Eligibility Criteria:

  • At least 18 years of age
  • Underwent transtibial amputation at least 18-months prior
  • Have a stable residual limb condition without active infections or significant oedema
  • Have ever used a prosthetic limb for daily activities
  • Are in good general health as determined by a medical professional
  • Do not suffer from claustrophobia or other medical conditions incompatible with medical imaging
  • Are willing and able to attend all study sessions
  • Are able to give written informed consent
  • Can understand written and verbal English.

What am I being invited to do?

  1. Read the Participant Information Sheet
  2. Undertake the Online survey and consent 
  3. Vital signs taken and external scan, MRI and CT scans of your residual limb at Jones radiology, SAHMRI CRIC.
  4. Group discussion session (~4 participants per session, approx. 2 hrs) and socket evaluation survey.
  5. Reflection diary – uploading photos/video of significant issues with prosthetic socket over 5 days.

An Honorarium of $150 will be presented to participants at the end of the study. Reimbursement will be available for some distance travelled and parking.
