What is the purpose of this trial?

This trial tests a new method to assist individuals with a history of diabetic foot ulcers. Researchers aim to determine if a special software and orthotic device can prevent new ulcers or even amputations. The treatment uses Noraxon myoRESEARCH software to analyze and correct gait, reducing stress on the feet. Candidates may qualify if they have a healed diabetic foot ulcer and are managing diabetes. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could enhance diabetic foot care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this gait analysis evaluation and orthotic is safe for diabetic foot ulcer patients?

Research has shown that using the Noraxon myoRESEARCH Software to study walking patterns and adjust shoe inserts is generally safe for participants. This software analyzes walking patterns and makes changes that might reduce the risk of new foot sores in people with diabetes. Studies have reported no major side effects from using this software. As this trial is in the "Not Applicable" phase, it focuses on gathering information about the treatment's effectiveness and safety in everyday situations. This indicates the treatment is considered safe enough for broader testing. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it uses Noraxon myoRESEARCH™ Software for gait analysis in a new way to address diabetic foot ulcers. Unlike traditional treatments that focus on wound care and pressure relief, this approach analyzes how a person walks to create customized orthotics. This personalized method aims to improve walking patterns and reduce pressure on ulcers, potentially speeding up healing and preventing future wounds. By tackling the problem at its source, this innovative method could offer a more effective solution for managing diabetic foot ulcers.

What evidence suggests that the Noraxon myoRESEARCH Software is effective for reducing diabetic foot ulceration?

Research has shown that using Noraxon myoRESEARCH Software to analyze walking patterns and adjust footwear can lower the risk of new foot ulcers in individuals with a history of diabetic foot ulcers. In this trial, all participants will receive the intervention involving this software. The software analyzes walking patterns and recommends shoe modifications to ease foot strain. This can reduce pressure, which often leads to ulcers. Early results suggest this method might decrease the likelihood of future ulcers or the need for amputations. It provides a targeted approach to protect and support feet, potentially improving health outcomes for those at risk. ^{1 2 4 5 6}

In a study of 31 participants with diabetes at high risk for foot ulcers, providing custom-made indoor footwear significantly improved adherence to wearing appropriate footwear, especially among those with initially low adherence, increasing from 65% at baseline to 87% at 12 months.

Despite the increase in footwear adherence, the one-year ulcer recurrence rate was 26%, indicating that while adherence improved, further research is needed to understand its impact on preventing foot ulcers.

Customized biomechanical foot orthoses (BFO) significantly improved kinematic parameters such as plantar flexion motion and hindfoot inversion in patients with hallux valgus (HV) deformities, indicating a positive effect on their gait mechanics.

While the BFO did not lead to statistically significant improvements in gait cadence, walking speed, and stride length, the observed trends suggest that BFOs may enhance overall mobility in individuals with HV deformities.

In a study of 61 participants with diabetes at risk for foot ulcers, the average daily wearing time of prescribed orthopaedic footwear was only 8.3 hours, with 66% of participants not adhering to the recommended wearing time of at least 60%.

Participants who consistently wore their orthopaedic footwear had significantly higher daily wearing times (12.7 hours) compared to those with inconsistent patterns (3.6 hours), highlighting the importance of stable wearing habits for effective prevention of foot ulcers.
