The overall goal of this project is to develop modular, lower-limb, powered orthoses that fit to user-specific weakened joints and control force/torque in a manner that enhances voluntary motion in broad patient populations. This project aims to establish feasibility of assisting different populations with these modular powered orthoses. The investigators hypothesize that assisting lower-limb musculature with modular powered orthoses will improve 1) lifting/lowering posture in able-bodied subjects and 2) functional outcomes in elderly subjects.

Lower limb amputation is common in the United States, with approximately 150,000 amputations annually. Most individuals walking with a prosthesis demonstrate asymmetrical loading-i.e., they favor the amputated side by placing more weight and increased ground reaction forces through the intact limb-which likely contributes to increased metabolic cost of walking. Lack of adequate muscular strength in the lower limb to attenuate these forces places increased stress on the joints, which may be displaced proximally, and may play a role in reported knee and hip pain in the intact limb. Lower limb muscle weakness following amputation has been well documented. Increasing quadriceps strength is important after an amputation because it is positively correlated with gait speed. Gait speed may also be associated with successful community mobility, which leads to improved quality of life following amputation. Individuals with amputation who resume an active lifestyle are able to maintain strength. However, these individuals represent a minority of persons with lower limb amputation; most individuals report more barriers than motivators to adopt an active lifestyle. Ischemic conditioning (IC) may strengthen leg muscles and reduce the metabolic cost of activity after amputation. In IC, the limb is exposed to brief, repeated bouts of ischemia (reduced blood flow) immediately followed by reperfusion. IC has been shown to improve muscle performance in healthy and diseased populations. IC has also been used more recently in patients with peripheral artery disease (PAD) as an intervention to improve function, such as walking ability. Acute exposure to IC increases muscle strength and activation, both in healthy, active individuals and in those with severe neuromuscular dysfunction, such as stroke survivors. IC also attenuates muscular fatigue. Increased fatigue resistance at submaximal contraction levels following IC may be due to increased neural activation of skeletal muscle. Changes in neural activation of muscle may be particularly beneficial during cortical reorganization after amputation. Reduced quadriceps fatigue during submaximal activities may also drive changes in gait kinematics, such as increased knee flexion during loading and mid-stance. Exposure to IC may also increase the oxidative properties of skeletal muscle, offering a direct pathway to reduce metabolic cost. Therefore, IC may lead to cellular changes that lower the metabolic cost of activity. The primary aim of this study is to quantify the benefits of acute and chronic IC on quadriceps strength and walking economy in individuals with PAD and history of lower limb amputation.

Carbon fiber custom dynamic orthoses (CDOs) and unloading ankle foot orthoses (AFOs) have shown varying levels of success in reducing forces acting on different regions of the bottom of the foot during gait. CDOs and unloading AFOs have shown differing offloading capabilities across different regions of the foots (hindfoot, midfoot, forefoot) which may be related to a distinct difference between CDOs and unloading AFOs: CDOs do not suspend, or distract, the foot away from the footplate. The purpose of this study is to determine the effects of CDOs and heel distraction height (the distance between the heel and the footplate) on limb loading and motion during gait as well as patient reported pain, and comfort.

Carbon fiber custom dynamic orthoses (CDOs) consist of a proximal cuff that wraps around the leg just below the knee, a posterior carbon fiber strut that stores and returns energy during gait, and a carbon fiber foot plate that supports the foot and allows bending of the posterior strut. The proximal cuff is a primary interface between the patient and the CDO and may influence comfort, preference, limb mechanics and loading, and effective stiffness of the CDO. The important role of the proximal cuff has not been examined. The purpose of this study is to determine the effects of CDO proximal cuff design on patient reported outcomes, limb mechanics and loading, and CDO mechanical characteristics.

This study is a prospective, randomized controlled trial designed to evaluate the effectiveness of Miro3D Wound Matrix plus Standard of Care (SOC) compared to SOC alone in treating Wagner Grade 1 diabetic foot ulcers (DFUs) and wound dehiscence in an outpatient setting. The trial is sponsored by Reprise Biomedical, Inc. and aims to explore whether the addition of Miro3D-a three-dimensional, acellular porcine-derived wound matrix-enhances wound healing outcomes compared to SOC alone. Purpose of the Study: The primary purpose of the study is to determine whether applying Miro3D in combination with SOC leads to improved healing of diabetic foot ulcers compared to SOC alone. Specifically, the study seeks to assess early wound healing progress at four weeks (as measured by percent area reduction and granulation tissue formation) as a predictor of complete healing by twelve weeks. Key Question the Study Seeks to Answer: Does the addition of Miro3D to standard wound care improve the healing rate and overall wound outcomes for patients with Wagner Grade 1 diabetic foot ulcers or dehisced wounds compared to standard care alone? Study Design Overview: Subjects who meet inclusion/exclusion criteria will be randomized into one of two groups: 1. Miro3D + SOC arm - receiving Miro3D weekly for 4 weeks, then biweekly if needed, for up to 12 weeks. 2. SOC alone (control) arm - receiving SOC without Miro3D. If the wound remains unhealed at 12 weeks in the SOC alone arm, participants may "crossover" to receive Miro3D treatment under the same schedule for an additional 12 weeks. Primary Endpoint: 1. Percent Area Reduction (PAR) and granulation tissue formation at 4 weeks, serving as predictors for wound healing at 12 weeks. Secondary Endpoints: 1. Quality of Life (QOL) improvements, including pain, mobility, and emotional well-being, assessed using a validated Wound/Ulcer-QOL tool. 2. Pain levels using a Visual Analog Scale (VAS) at each visit. Population: Approximately 30 adult subjects (15 per arm) with Wagner Grade 1 diabetic foot ulcers or dehisced wounds will be enrolled. Subjects must have adequate blood flow, demonstrate wound size criteria, and commit to offloading and follow-up care. Follow-Up: Subjects will be followed weekly through the 12-week study period. Healed subjects will undergo confirmation visits at 2 and 4 weeks post-closure. Subjects in the crossover arm will be followed for an additional 12 weeks if their wound was unhealed at the primary endpoint. Statistical Considerations: Data will be summarized using descriptive statistics, including wound measurements, infection status, and healing rates. Comparative analysis will be conducted between treatment groups and schedules (weekly vs. biweekly Miro3D application). Adverse events (AEs), serious adverse events (SAEs), and device-related events will also be documented. This study aims to generate clinical evidence supporting the use of Miro3D as a beneficial adjunct to standard wound care in promoting early and complete healing of diabetic foot ulcers.

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.

The goal of this study is to find out if using microprocessor-controlled prosthetic knees (MPKs), prosthetic knees with a built-in computer, improves health outcomes related to falls in adults who use above-knee prostheses. The main questions are: * Do individuals with MPKs have fewer fall-related health issues compared to those with non-microprocessor-controlled prosthetic knees (nMPKs)? * Do individuals with MPKs have increased mobility, faster walking speed, and improved quality of life compared to those with nMPKs? Participants who have recently received an nMPK as part of their regular care can join the study. Those randomized to the control group will keep using their nMPK, while those randomized to the intervention group will receive a stance-and-swing MPK or a stance-only MPK.

The goal of this investigational study is to evaluate the safety and clinical performance of Tropocells Autologous Platelet-rich Fibrin (PRF) for wound care for both males and females, ages 18-80 years old, with Grade 1 and 2, mild to moderate, neuroischemic diabetic chronic foot ulcers in subjects with Type 1 and Type 2 Diabetes Mellitus. The main question\[s\] it aims to answer \[is/are\]: Measure 1: Wound Closure with Tropocells Autologous PRF System for DFU Measure 2: Safety of Tropocells Autologous PRF System for DFU Researchers will enroll to acquire approximately 30 evaluable subjects with no comparison group. Run-In Phase (2 weeks): participants with chronic diabetic foot wounds will undergo a 2-week run in phase presenting to the clinic for weekly visits, for standard of care. Active Treatment Phase (12 weeks): participants that do not show a reduction of at least 20% may be qualified to advance to the active treatment phase where wounds will be evaluated and treated weekly in the research clinic to receive standard of care with Tropocells Autologous PRF System. Follow-up Phase (1 month and 3 months): participants with wounds that losed during the Active Treatment Phase ( 100% wound closure with two weekly assessments demonstrating persistent closure) will be advanced to the follow-up phase to show if the wound remains closed at 1 month and 3 months.

Why Other Patients Applied

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do Lower Limb Injury 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 Lower Limb Injury 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 Lower Limb Injury 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 Lower Limb Injury 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 Lower Limb Injury 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 Lower Limb Injury clinical trials?

Most recently, we added Motorized Orthosis for Lower Limb Injury, Terrain Locomotor Training for Amputation and Platelet Rich Plasma for Foot Ulcer to the Power online platform.
