Diabetic Foot UlcerNCT03717233
Assistive ExoSkeletons to Enable Wearable Rehabilitation Robotics
A study testing Exoskeleton in people with Diabetic Foot Ulcer and Diabetic Foot Ulcer Associated With Type II Diabetes Mellitus, run by Results Group LLC at 2 sites in United States.
Trial summary
Study will evaluate the use of lower-limb assistive exo-skeletons worn on the ankle and foot. Participants will wear the exo-skeletons and walk in a safe environment. Measurements will be taken to determine how the exo-skeletons affect the pressure on the feet of people with diabetic foot ulcer and how they walk. Read more about this study

About this study
Official title: Assistive ExoSkeleton & ExoTendon Platform to Enable Wearable Rehabilitation Robotics
Study will evaluate the use of lower-limb assistive exo-skeletons worn on the ankle and foot. Participants will wear the exo-skeletons and walk in a safe environment. Measurements will be taken to determine how the exo-skeletons affect the pressure on the feet of people with diabetic foot ulcer and how they walk.
Read the detailed description
Study will evaluate the use of lower-limb assistive exo-skeletons worn on the ankle and foot. Participants will include those with self-described history of Diabetic Foot Ulcer and age-matched healthy volunteers. Participants will wear the exo-skeletons and will be asked to walk 32 feet, and to stand quietly for 30 seconds.
Measurements will be taken to evaluate how the exoskeletons affect how people walk, and will also evaluate the pressure on the bottom of their feet. These measurements will be repeated multiple times to evaluate four different exo-tendon spring rates, and two sets of control shoes.
Exo-skeletons have been shown to reduce the pressure on the bottoms of people's feet and to reduce the effort to walk. This study is necessary to understand the contribution of different levels of exo-skeleton spring force to these effects.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ExoskeletonDevice
Ankle-foot exoskeleton - device to help reduce load on the bottom of the front of the foot
| Study group | Role | What they receive |
|---|---|---|
| Primary Arm | Experimental | Participants will be used as their own controls. Participants will be evaluated using exo-skeletons with non-motorized spring elements in parallel to the Achilles tendon. Up to 5 different levels of spring force will be evaluated to evaluate the impact upon plantar pressure and measures of fall risk. Receives: Device: Exoskeleton |
What is being measured
The primary outcome is the main question the study is designed to answer.
Forefoot plantar pressure
Measurements of the force and pressure on the bottom of the front of the foot
Measured: 30 minutes
Secondary outcomes (1)
Measures of fall risk
Measurements of postural sway, balance and gait speed to provide an indication of participant's risk of falling while wearing different shoes.
Measured: 30 minutes

Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Forefoot plantar pressure (time frame: 30 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03717233, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2020.
