To all lower extremity amputees…

Are you 18 years of age or older?
Do you use a prosthetic liner?
Are you willing to complete a 5 to 10-minute online survey?

A University of Pittsburgh Master of Science in Orthotics and Prosthetics student is studying the effect that the various climate regions of the United States has on the occurrence and severity of hyperhidrosis (excessive sweating) in lower extremity amputees who use prosthetic liners and the interaction effect of climate region, prosthetic liner type, and physical activity.

My research is on communication styles between people who have had an amputated limb and their prosthetist. The survey should take around 20-30 minutes to complete, and people who are interested in completing the survey can access it by copying and pasting the link below into their website browser: 

if participants wish to get in touch, my email is:

Are pain, ease of prosthetics use, or sensation important to you as a person with limb loss?

You may qualify for research studying how people think about risks and benefits of new limb prosthetic devices. We want to know your preferences about prosthetics. You will participate in a computer survey, at your convenience, about your experience with limb loss. This should take you about 30-45 minutes.

Invitation for Families to Participate

Researchers at the University of Washington invite parents, who have children between the ages of 6 – 12 years old who use lower extremity prostheses, to participate in a short online survey that will take only 10 minutes to complete.

We’re conducting a study to look at play barriers that might impact children who use lower extremity prostheses’ play behaviors. Play is a very critical occupation of children,, and barriers to play can impact children’s physical and psychosocial growth and development. Positive play experiences and interactions serve to build important cognitive, motor, and social competencies.

The information from this study will ultimately:

Develop an outcome measure that will better identify play barriers for children who use lower extremity prostheses.

Maximize participation in play, across a variety of environments, in children who use lower extremity prostheses.

Inform the development of pediatric lower extremity prostheses that better meet children’s needs for participation in play.

If you are a parent of a child between the ages of 6 – 12 years old, who uses a lower extremity prosthesis, and would like to participate in this survey, please go to the following link:

Thank you for your participation in this survey.

The GRAB lab at Yale University is conducting a research study on investigating how upper limb amputees use their prosthetic devices to complete daily tasks, such as eating, cleaning and washing. The data we gather will allow us to identify strengths and weaknesses in current devices and generate design guidelines that will lead to better prosthetics in the future.

We are currently seeking upper limb amputees to participate in the study. Participants should live within driving distance to New Haven, Connecticut. Residents of New York City and Boston are welcome to apply. Participants must be daily users of their prosthetic device and must have had the device for 6 months or over.

In the first part of the study participants will wear a head-mounted camera in their own homes while completing typical household tasks. In the second part, participants will travel to our laboratory at Yale University, where they will complete similar activities while their movements are recorded by a motion capture system.

Some further details may be found in the following document:

Participants who complete the study will be compensated $320 in addition to travel expenses.

The Department of Rehabilitation at Walter Reed National Military Medical Center (WRNMMC) is currently recruiting up to 105 individuals with (and without) lower-extremity trauma or amputations to investigate how spine motion affects loads in the low back, and how these motions/loads are related to the current health of the spine and tissues in the low back.

Eligibility: Age = 18-45 years

Unilateral transtibial or transfemoral amputation, or no injuries
No upper-extremity amputation(s) above the wrist Current (or no) low back pain

Time Commitment: a single 2-hour visit

Location: Biomechanics Laboratory, America Building (19), Room B314

Possible Benefits: Results from this study could improve our understanding of why persons with lower-extremity amputation are susceptible to low back pain.

For more information, contact:

1) Over the age of 18
2) Below-knee amputation on only one leg
3) Over a year since your amputation
4) Able to use your prosthesis, but you have difficulty doing high-level activities, such as running or jumping

Location of Testing
Walter Reed National Military Medical Center

  • Amputee Center
  • Prosthetics and Orthotics Service
  • Military and Advanced Training Center

Time Commitment
One year
First 6 months: 5 clinic visits and 2 prosthetic fittings
Second 6 months: 2 telephone calls to complete questionnaires

Purpose of Study

The purpose of the study is to learn if there are differences between a powered ankle prosthesis and the unpowered prosthesis you currently
wear. We will look at differences in how you walk in both prostheses, if one allows you to use less energy when you walk, and if one allows you to participate in and perform more activities than the other.

There is no guarantee that you will benefit from this study, however other research studies have shown that the use of a powered ankle prosthesis may decrease the stress on your un-amputated leg and may reduce the energy you require to complete daily tasks.
