Powered Foot Prosthesis and Physical Therapy for Lower Limb Problem
New York, New York
Individuals living with Transfemoral Amputation, enrolled equally at the Veterans Affairs New York Harbor Healthcare System (VANYHHS) and Walter Reed National Military Medical Center (WRNMMC), will be fit with a powered ankle-foot prosthesis. All subjects will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment at baseline utilizing their current passive prosthesis. Subjects will then be randomly assigned into 2 equal groups: Powered device with an 8-session intensive, device-specific PT intervention (Group A); or powered device with current standard of practice (Group B), with includes basic device education, but no PT intervention. Subjects in Group A will undergo a 4-week PT-based intervention, which will isolate the contribution of device specific effects from rehabilitation effects. Group B will receive the current standard of practice, which does not include any formal rehabilitation. All users will undergo a full gait analysis, functional measures, neurocognitive/cognitive, and pain assessment after 4- and 8-weeks of use.

Prosthetic Suspension Systems for Lower Limb Amputation
New York, New York
Individuals with lower extremity amputation are often challenged by complications that arise from poor prosthetic fit, including movement of the residual limb in the socket, known as pistoning. Pistoning can lead to gait instability, skin problems, and pain. Different prosthetic suspension systems have been developed to decrease this motion, including elevated vacuum suspension, which utilizes a pump to draw air from the socket. However, scientific analyses to understand the movement between the limb and socket have yet to be performed with a high level of accuracy. This study will use a state-of-the art imaging technique, known as dynamic stereo x-ray, to quantify the 3D movement of the residual limb in the socket. It is hypothesized that dynamic stereo x-ray will be a sensitive method to measure differences in residual limb movement between 2 different socket suspension techniques: suction and elevated vacuum suspension. This information is critical for advancing prosthetic treatments to reduce secondary conditions and degenerative changes that result from poor prosthetic fit.

ASTERISK System for Below Elbow Amputation
Holliston, Massachusetts
The goal of this proposed project is to evaluate the effectiveness of our novel wireless electrode system, which the investigators refer to as the ASTERISK system, on transradial prosthesis users. There are numerous benefits to the upper limb prosthesis community being able to utilize wireless electrodes. These benefits include allowing for the use of a prosthetics liner to assist with fit and comfort, easier implementation of EMG-controlled prosthesis for individuals with osseointegration, and additional EMG electrode location options if the muscle activity captured within the prosthetic socket does not provide reliable prosthesis control. The investigators intend to use this data to develop the ASTERISK wireless electrode system into a commercial product. The findings will also be shared with the research community to help drive the design of future devices.

Prosthetic Ankle-Foot System for Amputation
Minneapolis, Minnesota
Veterans with leg amputations have limited footwear options because their artificial feet do not change shapes for different shoes. Studies have shown that women with amputations receive more frequent prosthetics care than men, but are less satisfied with the fit, comfort, and appearance of their prostheses. The investigators' previous research indicates that women Veterans would like to be able to wear a broader variety of footwear, and those who perceive more footwear limitations tend to have poorer body image and community participation. A new prosthesis designed by the investigators' group allows Veterans with amputations to use their footwear of choice using 3D-printed artificial feet with a single ankle. The novel prosthesis will be tested in this project with women Veterans with amputations to determine the impact of improving footwear options on body image and community participation.

eOPRA Implant + Magnetic Bead Tracking for Amputation
Cambridge, Massachusetts
The e-OPRA Implant System, is a further development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System. The e-OPRA Implant system is an implant system for direct skeletal anchorage of amputation prostheses. The added feature in the e-OPRA Implant system, is a bidirectional interface into the human body that allows permanent and reliable communication using implanted electrodes. These electrodes will provide long-term stable bioelectric signals for an improved control of the prosthetic limb. The Magnetic Bead Tracking System, which will be implanted and used in combination with the e-OPRA Implant system, is an investigational device that consists of pairs of magnetic beads, and a set of magnetic field sensors that measure and track the length of muscles and the speed at which they move in real-time. When the beads are implanted in muscle in the residual limb of an amputee, the muscle length signal is communicated to an investigational, robotic ankle-foot prosthesis. The purpose of the study is to evaluate the feasibility of a transtibial amputee with the e-OPRA Implant System and Magnetic Bead Tracking System exhibiting full neural control over a neuro-mechanical prosthetic system.
A maximum of seven subjects will be enrolled. Each subject will undergo one or more surgeries where the e-OPRA Implant System and Magnetic Bead Tracking System will be implanted. The subjects will participate in follow-up sessions the last of which occurs approximately 24 months after the surgery. This is a prospective, non-randomized, uncontrolled study.

Prosthetic Knees for Above-Knee Amputation
Austin, Texas
The goal of this proposed project is to gather community-based data from the K2-level Transfemoral Amputee (TFA) population to aid in evidence-based prescription of powered prosthetic knees (i.e., choosing the right device to maximize the benefit for each patient). The investigators intend to use this trial data along with a concurrent study being conducted within the K3-K4 level population to guide the implementation of effective prescriptions towards those that can benefit most from a given device and limit prescription to those who would not see benefit in order to ensure the most judicious use of Department of Defense (DoD) and Veteran's Affairs healthcare dollars. The findings will also be shared with the research community to help drive the design of future devices by identifying what features and functions are most beneficial to which patient populations when the devices are used outside of the laboratory. In summary, more community-based data on how powered prosthetic knees compare with the current standard in TFA populations is needed to allow for improved clinical decision making and clinical outcomes.

Prosthetic Suspension Systems for Lower Limb Prosthesis Wearers
Seattle, Washington
Individuals with lower limb amputation often complain about uncomfortable residual limb skin temperatures and the accumulation of sweat inside their prostheses. It doesn't take long before the presence of sweat on the residual limb leads to a lack of confidence in the security of their prosthetic suspension. Some circumstances allow the wearer to doff the prosthesis before it falls off, wipe it and the residual limb dry, and then don it again. Another option is to simply reduce the intensity of activities before sweat becomes a problem. However, the Warfighter amputee may not be afforded such accommodations. For these service personnel, inadequate moisture management can significantly limit or inhibit their mobility. The objective of the proposed research is to provide lower limb amputees who work in demanding environments with a prosthesis that remains secure despite profuse residual limb sweating without compromising residual limb health and comfort.
The aim of this research is to compare three different, lower limb prosthetic suspension systems and identify which is most effective at maintaining a secure adherence when worn in conditions that result in profuse sweating. The investigators also aim to compare how the three study prostheses effect residual limb skin health and comfort when participants pursue their usual activities in the home, work, and community environments.
To achieve these aims, the investigators will to recruit 25 below-knee amputees. Each subject will be asked to be asked to wear: (1) their as-prescribed prosthesis, (2) a prosthesis with a perforated elastomeric liner that allows sweat to flow away from the skin, and (3) a prosthesis that has a battery and body-weight activated pump to flow air between the prosthesis and the residual limb skin, allowing expulsion of any accumulated sweat. Subjects will wear each of these prostheses in the home, work, and community environments for two weeks, after which the investigators will measure their residual limb health and comfort. Subjects will then walk on a treadmill in a room whose climate will be set to Middle East-like conditions: 35 °C (95 °F) and 50% relative humidity. After 30 minutes, the investigators will measure any slippage of their prosthesis relative to their limb and how much sweat is expelled. The investigators hypothesize there will be differences in the amount of slippage, residual limb health, and comfort between the three prostheses.

Caregiver-Assisted Limb Scanning for Amputees
Seattle, Washington
When the prosthetic socket of a Veteran with a lower limb amputation no longer fits or is damaged beyond repair, a new prosthetic socket is warranted. The provision of a new socket requires multiple clinical visits which can place a high travel burden and potential pandemic exposure stress on Veterans who live in rural communities far from VA Medical Centers or alternative prosthetic clinics. This research seeks to determine if one of the in-person visits traditionally needed to obtain a well-fitting prosthesis can be performed remotely with the assistance of a helper. The investigators seek to discover if an untrained individual (a helper) can wield inexpensive, easy to use, digital technology to capture the shape of a residual limb to see if it can be used to fabricate a prosthetic socket that fits at least as well as one fabricated by a prosthetist using traditional, hand casting methods in the clinic.
The expected result of this research is an evidence-based prosthetic fabrication process that reduces Veteran travel burden while providing a prosthesis that fits at least as well as the current standard-of-care. The upshot is a clear improvement in prosthetic provision for Veterans, particularly for those who live in rural communities.
To make this determination, the investigators will perform a between-subject experiment with two specific aims. To determine differences in goodness of fit between the two study sockets, the investigators will use both patient reported outcomes, and measurements of the pressure applied to the distal end of the residual limb.
Specific Aim 1: Determine if patient reported outcomes, by subjects wearing a prosthetic socket whose shape was captured with study helper assistance, are at least as good as those reported by subjects wearing a socket whose shape was captured by a prosthetist. The investigators propose to recruit Veterans with a below knee amputation and their study helpers to participate in a human subject experiment. Participants will be randomly assigned and fit with either a prosthesis made with study helper assistance and digital methods, or one made wholly by a prosthetist using traditional methods. Patient reported outcome metrics will be collected while the subject is still wearing their as-prescribed socket at the beginning of the study (baseline), and again after wearing the study prosthesis for two weeks.
Specific Aim 2: Determine if distal end residual limb pressure, measured from a group of individuals fit with a prosthetic socket whose shape was captured with study helper assistance using digital methods, are no worse than those measured from a group of individuals fit with a prosthetic socket whose shape was captured by a prosthetist using traditional methods. Concurrent with the human subject procedures briefly described above, the investigators propose to fabricate duplicates (copies) of the two prosthetic sockets used by each subject in Specific Aim 1. A novel sensor will be embedded in these duplicate sockets which can measure the pressure applied to the distal end of the residual limb. Measurements of distal end residual limb pressure while standing and walking for both the as-prescribed and study sockets will be collected at the beginning of the study (baseline), and again after two weeks.
The data from the investigators' experiments will be used to determine if residual limb shape capture by a helper using digital technologies can be used to make prosthetic sockets that fit at least as well as those made by a prosthetist using traditional, hand casting techniques.
One third of all Veterans live in rural communities far from VA Medical Centers. When Veterans with a lower limb amputation need a new prosthetic socket, attending in-person clinical visits can be a challenge. If the hypotheses are supported, this research will provide evidence to support the use of digital technology as part of clinical practice, enabling a remote, study helper enabled alternative to one of the in-person clinical visits needed to fabricate a well-fitting prosthesis.

Personalized Instrument for Total Shoulder Arthroplasty
Montréal, Quebec
Total shoulder arthroplasty is an effective procedure to improve patients function and to relieve shoulder pain in cases of glenohumeral arthritis. The main challenge of this procedure is implanting the glenoid component. Indeed, surgical exposure is difficult and proper visualization of the glenoid is demanding. The current free-hand method is not precise and especially unreliable in glenoids with severe deformity. Inappropriate reaming and glenoid positioning can cause more bone loss during surgery.
In anatomic prostheses, glenoid component fixation is demanding and is the first component to present loosening at long term follow-up. When it comes to reverse arthroplasty, the glenoid component, once again, requires the most attention. Malpositioning of the glenosphere can cause notching, loosening, and instability.
In order to prevent these complications, precision in glenoid implantation is key. To this end, intraoperative computer navigation would be a helpful tool, but the increased expenses in computer equipment represent massive costs and possibly increases in surgical time. A more affordable option is a personalized guide, for which the only extra expense is the customized guide. These guides are based on precise 3D CT scan templates. Previous studies have evaluated the precision of the guide in vivo and in vitro, but none have measured it in a randomized study. As it represents additional costs, its efficacy needs to be proven before widespread use.
This method may also provide secondary benefits, such as decreasing operating time, lowering short- and long-term complications, and improving efficacy.
The objective of this study is to evaluate the performance of a patient specific glenoid guide.

Weight-Bearing CT Scans for Periprosthetic Fractures
London, Ontario
Total knee arthroplasty (TKA) is a surgical procedure commonly conducted for patients with end-stage knee osteoarthritis, often leading to improved pain relief and function. However, for patients that have suffered an associated periprosthetic fracture, a broken bone that occurs around the implant of a TKA, they may receive sub-optical care due to a lack of a trustworthy assessments for component fixation and fracture healing in the literature. The prevalence of TKA surgeries is increasing annually and is projected to rise further due to an ageing population and obesity issue. By extension to this primary surgery, more Canadians will require an invasive revision surgery that risks patient morbidity and mortality. Thus, it is imperative to set a standard for fixation and bone healing assessments to lessen revision burdens and improve patient outcomes. CT imaging can effectively visualize areas of incomplete bone ingrowth that may be hidden from overlapping anatomy on plain radiographs, which remains the go-to imaging modality for orthopaedic surgeons to assess periprosthetic fracture healing. The purpose of this prospective cross-sectional study is to examine the efficacy of weight-bearing CT as a diagnostic tool for 20 participants who experienced a distal femur periprosthetic fracture and underwent revision surgery using a fracture fixation plate and screws. Participants will be scanned under loaded and unloaded conditions. Radiographic outcomes will be evaluated, including bone segment displacement and its relation to participants' reports of pain.

Articulating Spacers for Knee Infections
Chicago, Illinois
In the US, if an infection in an artificial knee joint doesn't heal with antibiotics alone, the standard treatment is a two-stage revision of the artificial knee. In the first stage, the surgeon will remove the artificial knee and clean out the area around the knee. They will then place an antibiotic spacer. An antibiotic spacer is a type of artificial joint that will release antibiotics into the knee space continuously over time. The spacer allows only very basic function of the knee. The patient may need to use crutches or a walker while the antibiotic spacer is in place. After surgery to place the antibiotic spacer, the surgeon may prescribe a course of antibiotics as well. Because the antibiotic spacer is not as durable as a regular artificial joint, after the infection is gone, another surgery is required to take the spacer out and put a new artificial knee joint in.
There is another way for artificial joint infections to be treated. This is a one-stage revision. In this treatment, the surgeon will remove the artificial knee and clean out the area around the knee. Then the surgeon will place a new artificial knee in using a special kind of cement that contains antibiotics. The cement will release antibiotics into the knee space continuously over time (the surgeon may prescribe a course of antibiotics as well). The new artificial joint with antibiotic cement will function almost the same as the original artificial knee. This means that while the infection is healing the patient will be able to do most of the regular daily activities. However, the antibiotic cement is not as durable as what is normally used to implant an artificial knee. The artificial knee with the antibiotic cement may need to be replaced with a regular artificial knee. When replacement will need to be done is dependent on patient weight, bone strength and activity level, among other things. When it is time to replace the antibiotic cement artificial knee, the patient will have another surgery where the surgeon will take the antibiotic cement artificial knee and put a new artificial knee joint in.
Investigators know that both the one- and two-stage revision work equally well to heal the infection, but investigators don't know which patients prefer or which provides better function after many years. This study will randomly assign patients to receive either a one-stage or two-stage revision and then follow them for 5 years to ask them about pain, function, and satisfaction.

Frequently Asked Questions
How much do Prosthesis clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.
How do Prosthesis clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Prosthesis trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Prosthesis is 12 months.
How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.
What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.
Do I need to be insured to participate in a Prosthesis medical study?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.
What are the newest Prosthesis clinical trials?
Most recently, we added Prosthetic Foot + Physical Therapy for Leg Amputation, Probiotics for Prosthetic Joint Infection and Condylar vs Stabilized Bearing for Knee Replacement to the Power online platform.
