About the study.

Performance tests can provide a clinician with valuable information about a prosthesis user’s mobility. These tests are often used at a prosthetics clinic, but can take a long time to administer or include tasks that are not appropriate for all types of people. This study is being conducted in order to develop a new test that can be administered quickly, provides clinicians with useful information, and measures mobility across a broad range of users. The test developed for this study will be free for clinicians and researchers to use when the study is complete.

Is this study right for me?

You may be eligible to participate if you…

Our study coordinators can answer any questions you might have
and help you determine if this study is a good fit for you.   

What to expect...

If you choose to participate, you will be asked to attend a single 60-90 minute session at a local clinic or meeting space. The session will consist of the following activities:


Consent to participate and complete a survey

After learning about the study from our staff, you will be asked to sign a consent form and complete a survey with questions about your health.


Provide information about using your prosthesis

A research team member will check your vitals, record body measurements, and ask questions about activities you do on a regular basis.


Complete a variety
of physical activities

A staff member will guide you through the test by providing instructions and a demonstration for each task. Some tasks may seem easy, and others may be more challenging. Examples of the activities include standing in place for 30 seconds, rising from a chair, walking short distances, and stepping over objects.


Receive $50 for participating

After you complete the test, or choose to stop, you will receive $50 and a huge thank you from our research team!
