Brief Summary

The study aims to investigate if combined modulated ultrasound and electric current stimulation (CUSECS) is an effective adjunctive treatment to use to treat diabetic foot ulcers when compared against usual care. Consenting patients with diabetic foot ulcers (DFUS) and meet the inclusion criteria will be randomly allocated in to either an experimental group or a control group. The experimental group will receive the adjunctive CUSECS treatment along their usual treatment for their diabetic ulcer. They will be required to attend the Diabetic Foot clinic in St. James's hospital twice a week for a maximum of eight weeks. The CUSECS is provided by attaching small electrodes around the ulcers to provide electric current stimulation. A probe is used on the ulcers to provide the ultrasound waves. Both aiming to increase the blood flow to an area to increase wound healing. The control group will be required to attend the diabetic foot clinic for their usual care for their diabetic foot ulcer once a week for a maximum for eight weeks. Once a week both groups ulcers will be assessed and measured and a photograph solely of the wound will be taken for documentation of wound healing. Wound pain as determined using the 0-10 Numeric pain rating scale will also be measured once a week. The movement in participant's ankle will be measured (flexion, extension, inversion) at the start and at the end of the study to see if treatment has improved its movement. As part of this study participants' will also be requested to fill out a SF-36 questionnaire at the start and at the end of the 8 week trial. This questionnaire evaluates a person's health related quality of life in which the research wants to see if it is affected by a diabetic foot ulcer. The self-efficacy of participants will also be assessed using PROMIS® Item Bank v.1.0 - General Self-Efficacy at the start and at the end of the 8 week trial. The cost of treatment for each arm will be calculated taking into account both direct (cost of treatments, consumables etc.) and indirect costs (loss of earnings, travel, parking etc.). Therefore, as part of this study, participants will be asked about mode of transport and transport time to and from the clinic and if their diabetic foot ulcer has affected their ability to work. Diabetic foot ulcer reoccurrence rates will be monitored in both groups by a follow up appointment 4 weeks after each group completes treatment or monitoring. Data from both groups will be examined and compared to see if CUSECS is effective in healing DFUs. The primary outcome of interest is wound healing and is determined by the number of wounds healed and the time to complete wound healing within eight weeks. All data will be stored confidentially. The study hypothesis is that there is be increased healing rates in subjects treated with CUSECS in combination with standard care compared to those treated with standard care alone. This study aims to provide evidence for continuing improvement in treatment for those suffering with diabetic foot ulcers.

Study Arms (2)

Control group

NO INTERVENTION

The control group will be required to attend the diabetic foot clinic for their usual care for their diabetic foot ulcer with weekly review for a maximum of eight weeks. They will also have a follow up appointment 4 weeks after completion of treatment.

Experimental Arm

EXPERIMENTAL

A device- BRH-A2 wound healing device will provide Combined ultrasound and electric current stimulation (CUSECS) treatment which is the intervention for this arm. Participants in this group will receive an adjunctive combined ultrasound and electric current stimulation (CUSECS) treatment along their usual treatment for their diabetic ulcer twice weekly for 8 weeks using the BRH-A2 wound healing device. They will also have a follow up appointment 4 weeks after completion of treatment.

Device: BRH-A2 wound healing device

Interventions

Combined ultrasound and electric current stimulation (CUSECS) is a combination therapy provided by the BRH-A2 wound healing device. This study is testing the effectiveness of the treatment CUSECS. The electric current stimulation is provided by attaching small electrodes around the ulcers. A probe is used on the ulcers to provide the ultrasound waves. Both aiming to increase the blood flow to an area to increase wound healing.

Masking Details
Analysis of data will be blinded and carried out by a statistician. Patient data will be coded and not identifiable directly. The key to the code book information will be secured separately from the dataset in an encrypted file, which will only be accessible by the researcher and the supervisors of the study. Therefore the each arm will be coded and none identifiable to the outcome assessor.

Model Details: Participants will be randomly allocated into an experimental arm and a control arm of the study. The experimental group will receive the adjunctive CUSECS treatment along their usual treatment for their diabetic ulcer twice weekly for 8 weeks using the BRH-A2 wound healing device. They will also have a follow up appointment 4 weeks after completion of treatment. The control group will be required to attend the diabetic foot clinic for their usual care for their diabetic foot ulcer with weekly review for a maximum of eight weeks. They will also have a follow up appointment 4 weeks after completion of treatment.
