Trial Summary

What is the purpose of this trial?

This trial is testing special shoes for patients with PAD to help them walk better and with less pain. The shoes provide an extra boost with each step, which can improve mobility and quality of life for these patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it requires that your blood pressure, lipid, and diabetes medications be stable for 6 weeks before joining.

What data supports the effectiveness of the treatment Assistive tennis shoes for Peripheral Arterial Disease?

Research on rocker-soled shoes, which are similar to assistive tennis shoes, shows they can help people with calf claudication (pain due to poor blood flow) walk longer distances and reduce pain. This suggests that assistive tennis shoes might also be effective for people with peripheral arterial disease.12345

Are special shoes for peripheral arterial disease safe for humans?

Studies on rocker-soled shoes for peripheral arterial disease and cushioned therapeutic footwear for diabetic patients suggest these shoes are generally safe and may help reduce pain and foot lesions.25678

How do special shoes for peripheral arterial disease differ from other treatments?

Special shoes for peripheral arterial disease, like rocker-soled shoes, are unique because they are designed to reduce the workload on calf muscles, which can help increase walking distance and reduce symptoms of calf claudication (pain caused by too little blood flow during exercise). Unlike drugs or surgical options, these shoes offer a non-invasive way to improve mobility and quality of life for patients.123910

Eligibility Criteria

This trial is for individuals who can consent, have chronic leg pain during exercise due to PAD with an ankle brachial index below 0.90, and stable blood pressure, cholesterol, and diabetes management. It's not for those with severe PAD causing rest pain or tissue loss, recent ischemic events in the legs from clots or trauma, or walking issues caused by other health problems.

Inclusion Criteria

Be able to give written, informed consent
My blood pressure, cholesterol, and diabetes treatments have been stable for 6 weeks.
Your ankle brachial index at rest is less than 0.90.

Exclusion Criteria

I have severe leg pain or tissue loss due to poor blood flow.
I recently had a blood clot or injury affecting my leg.
My ability to walk is limited due to conditions not related to leg pain from walking.

Treatment Details

Interventions

  • Assistive tennis shoes
Trial OverviewThe study tests special assistive tennis shoes designed for people with Peripheral Artery Disease (PAD) to see if they help reduce pain and increase physical activity compared to standard shoes. The goal is to improve daily living activities and potentially decrease related health risks.

Findings from Research

Patients with peripheral artery disease reported positive experiences with the ankle-foot orthosis (AFO) in terms of usability and cost-effectiveness, indicating that the device was easy to use and had no out-of-pocket costs during the 3-month intervention.
Despite initial positive feedback, challenges related to motivation and the AFO's impact on daily activities led to lower compliance after the intervention, highlighting the need to address patients' perceptions to improve long-term use and physical activity.
