About this study
Official title: Saving Life and Limb: Functional Electrical Stimulation for the Elderly With Peripheral Artery Disease
This study will take the first step to improve public health for millions of Americans with Peripheral Arterial Disease who have extreme difficulty walking due to leg pain. The investigators will assess a proof of concept, home administered, functional electrical stimulation (FES) system to resolve pain, improve walking, and enhance quality of life.
Read the detailed description
This study will evaluate an innovative approach to reduce the debilitating symptoms of peripheral arterial disease (PAD) and ischemic pain during walking (intermittent claudication) by using a new Functional Electrical Stimulation (FES) system. The investigators hypothesize that combining the FES and walking one hour/day (FES+Walk) will significantly reduce pain during walking, improve locomotion, and enhance quality of life when compared to walking one hour/day (Walk) alone after 8 weeks of intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FES (Gait MyoElectric Stimulator)Device
Functional Electrical Stimulation (FES) will be tested in a group of peripheral arterial disease patients using the Gait MyoElectric Stimulator. The FES device will be applied to the calf and shin muscles on both of the patients legs.
| Study group | Role | What they receive |
|---|---|---|
| Walk Group | No intervention | This group of patients are part of the walk group. They will be encouraged to walk and will receive standard care, defined as conservative (non-surgical) management of signs and symptoms, including prescriptive medications to improve circulation and manage pain, determined by their attending physician on a case by case basis. |
| FES + Walk Group | Experimental | This group of patients will participate in Functional Electrical Stimulation (FES) and exercise. This group will receive functional electrical stimulation as an intervention. The FES device will stimulate (activate) the calf and shin leg muscles of both legs while the patient is walking. This group will also receive standard care, defined as conservative (non-surgical) management of signs and symptoms, including prescriptive medications to improve circulation and manage pain, determined by their attending physician on a case by case basis. Receives: Device: FES (Gait MyoElectric Stimulator) |

We will measure the time (seconds) to complete the test from baseline to end of intervention and end of post-intervention
Measured: Initial, baseline assessment, assessment at the end of 8 weeks intervention and final assessment at 16 weeks (8 weeks post- intervention)
Change from initial assessment, baseline, end of intervention and final assessment using the Intermittent Claudication Questionnaire (ICQ)
We will record and measure the questionnaire score from baseline to end of intervention and end of post-intervention
Measured: Initial, baseline assessment, assessment at the end of 8 weeks intervention and final assessment at 16 weeks (8 weeks post- intervention)

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing FES (Gait MyoElectric Stimulator) in people with Peripheral Arterial Disease, run by MultiCare Health System Research Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Change from initial assessment, baseline, end of intervention and final assessment using the Perceived Pain Intensity Scale (time frame: Initial, baseline assessment, assessment at the end of 8 weeks intervention and final assessment at 16 weeks (8 weeks post-intervention)). The study lists 3 primary outcomes in all. 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 NCT02384980, 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 16 Aug 2016.
