Researchers at Altec, Inc (http://www.delsys.com) are developing new ways of controlling prosthetic limbs. We are looking for volunteers with transradial (forearm) amputation to participate in a research study where sensors will be placed on the forearm of your residual limb to record muscle activity. You will perform simple muscle contractions intended to open and close the hand of your residual limb.A prosthesis is not required. Single or multiple 2-3 hour recording sessionsmay be requested.

Research will be conducted onsite at Altec Inc, 23 Strathmore Rd, Natick, MA 01760

Payment will be provided on an hourly basis at $20/hr. Reimbursement is available for ground transportation.

Study Requirements
Male or female
16-65 years old
English speaking
At least 3 months post trans-radial amputation
Otherwise healthy with no neurological disorders
Must ambulate without assistance
Prosthetic limb not required for this phase of the study

If you meet the study requirements and are interested in participating, please contact Dr. Serge Roy at (508) 545-8235 or sroy@delsys.com for more information.

­Nicolas Burden and colleagues at Lancaster University, United Kingdom, are setting out to explore how an individual’s thoughts and feelings about amputation might affect the amount they use a prosthetic limb. They hope that the findings from the study will help to inform services helping people recover after a limb amputation.

The team at Lancaster would like to hear from individuals who have an amputated limb, access to a prosthetic limb and are 16 years of age or above.

If you fit the description above, consider taking part in the brief online study by following
this link; http://www.lancaster.ac.uk/shm/study/doctoral_study/dclinpsy/research/nicburden/

Or contact Nicolas directly at n.burden@lancaster.ac.uk if you have any questions or to
request a paper copy of the study.

­Researchers at the University of Michigan invite individuals with upper limb loss to participate in an online research survey regarding novel prosthetic technologies. The goals of this study are to:

  • Evaluate general interest in new prosthetic technologies
  • Determine whether demographic factors (like age or level of amputation) affect level of interest in new prosthetic technologies

Your input on these matters is valuable and can help researchers in establishing design criteria for future prostheses.

You are eligible to participate if:

  • You are 18 years of age or older
  • You have an upper limb amputation at the wrist or higher

Participants will receive a gift card for completing the survey.

If you would like to participate, please go to: tinyurl.com/UMOPsurvey. The survey may also be accessed at: https://umich.qualtrics.com/SE/?SID=SV_3DTnv98hZjIfsRD.

For more information about this study, please contact Susannah Engdahl at sengdahl@umich.edu.

The principal investigator of this study is Deanna Gates, PhD (gatesd@umich.edu). Dr. Gates runs the Rehabilitation Biomechanics Laboratory at the University of Michigan.

We are conducting a research study to develop new prosthesis control technology. This technology uses electrical signals recorded from muscles during muscle contraction to control an upper limb prosthesis.

The outcome of this study may someday allow upper limb amputees to control movements of a prosthesis more naturally and intuitively.

ABOUT THE STUDY

  • As a participant, you will be asked to perform low-level physical activities such as arm reaching, feeding motion, opening/closing your hand, and wrist movement.
  • The research study will be conducted at NC State University in Raleigh, NC.
  • Compensation is $25/hour with a minimum of $50/visit.
  • Participants residing far from our testing center may be eligible for travel and lodging reimbursement.

YOU MAY BE ELIGIBLE IF YOU ARE

  • Between the age of 18 and 70
  • At least 1 year post-amputation
  • With amputation between the elbow and wrist
  • Free from cognitive impairment

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.

Eligibility
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.

Version 4: 11/21/2014

Researchers at the University of Illinois at Chicago, in collaboration with practitioners at Scheck and Siress Orthotics and Prosthetics, are trying to understand how different socket suspension systems affect how much you use your prosthetic, your balance confidence and your locomotor capabilities.

Your participation would involve filling out short on-line surveys from home. The total time to complete all surveys is 15-20 minutes and you will be compensated for your time.

We are looking for participants that meet the following criteria:

  • Must be at least 18 years of age
  • Must be at least 1 year since amputation
  • Must be using current prosthetic for at least 6 months
  • Must have, or have access to an active email account
  • Must walk without the use of a cane or walker
  • Must answer yes to the following: “I can walk continuously for 6 minutes.”
  • Must not currently use a vacuum assisted socket suspension system

For further information, please contact the primary investigator, Noah Rosenblatt, PhD, at 312-996-2747.

This study is funded by the American Orthotic and Prosthetics Association

A multi-center study is underway utilizing an investigational medical device for people with post-amputation pain. If you are experiencing moderate to severe post-amputation pain not controlled by medication, we invite you to learn more.

Qualifications for study participation include:

  • One amputated lower limb
  • Frequent and recurring amputation pain
  • Willingness to undergo surgery
  • 21 years of age or older

The purpose of this clinical study is to evaluate whether electrical nerve block is a safe and effective treatment for patients with post-amputation pain. You will not be charged for any study related appointments or procedures.
