Clinical Trial Summary

A clinical study at the Baylor College of Medicine, Division of Vascular Surgery and Endovascular Therapy, is being proposed to test the efficacy of a novel electrical stimulation platform named the Tennant Biomodulator designed by AVAZZIA to accelerate wound healing, relieve pain and improve mobility in patients with diabetic foot ulcers.

Description:

Electrical stimulation may offer a unique treatment option to heal complicated and recalcitrant wounds, improve flap and graft survival, and even reduce the likelihood of ulceration. Electrical stimulation has been suggested to reduce infection, improve cellular immunity, increase perfusion, relieve pain, improve plantar sensation, and accelerate wound healing.

Electrical stimulation could have positive effect on not only increasing skin perfusion in patients with diabetes but also could improve mobility and balance via enhancing plantar sensation as demonstrated in our recent study. Thus, plantar stimulation not only may be beneficial to accelerate wound healing in diabetic foot ulcer (DFU) patients but also may assist to improve mobility and reduce the likelihood of recurrence of ulcers.

This study is proposed to examine the effectiveness of an innovative portable electrical stimulation platform (Tennant Biomodulator by AVAZZIA) to accelerate wound healing in DFU patients. It is hypothesized that 1) electrical stimulation will have an immediate effect on increasing skin perfusion (immediate benefit) and 2) daily use of the Tennant Biomodulator for 4 consecutive weeks is effective to speed up wound healing, increase skin perfusion, reduce pain, and improve balance and mobility in DFU patients (long term benefit)

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change From Baseline in Skin Perfusion in Response to Electrical Stimulation	Lower-extremity skin perfusion will be assessed using a skin perfusion pressure device (PADIQ Sensilase). This device emerges pressure with a cuff placed around the calf muscle that has internal sensors. Then, the cuff is slowly released letting circulation to re-enter which is detected by the sensors.	an average of 60 minutes from baseline
