Brief summary

An open multicenter trial to document the efficacy and safety of two therapeutic Extremely Low Frequency Magnetic Fields stimulation devices to promote wound healing of Diabetic Foot Ulcers.

Detailed description

An open multi center trial to document the systemic effects and safety of Extremely Low Frequency Electromagnetic Fields (ELF-MF) stimulation on healing of Diabetic Foot Ulcers (DFU). The study will be performed in two sites: Monterrey, Nuevo Leon, with patients from Medical Services of the Autonomous University of Nuevo León, and Cuernavaca, Morelos with patients from Regional General Hospital of Cuernavaca N. 1 IMSS, and Health Services of Morelos. Two ELF-MF investigational exposure systems will be used to stimulate blood at different anatomical regions to enhance wound healing upon peripheral blood mononuclear cell migration to the ulcer site. a) In Monterrey, Nuevo Leon, where DFU subjects should be exposed at either forearm with a sinusoidal oscillating magnetic field of 120 Hz with nominal ELF-MF amplitude of approximately 0.6mT-0.8mT (6-8 Gauss) RMS 2 hours/day, 2 times/week. and b) In Cuernavaca, Morelos, where DFU subjects would be exposed at the thorax with a stimulation system in a quasi-Helmholtz configuration, for 25 minutes/day, 2 times/week to a sinusoidal oscillating magnetic field of 120 Hz, with nominal ELF-MF amplitude of approximately 0.6mT-0.8mT (6-8 Gauss) RMS. Treatment period for both groups will be 14.2 weeks or upon a complete healing. In each treatment session, evolution of ulcer healing should be recorded photographically. Efficacy and adverse effects will be searched for during treatment, short-term (\<1 year), and long-term follow-up in both groups (up to 7 years).

Interventions

DEVICEForearm tissue exposure with ELF-MF

The treatment was delivered 2 hours/day, 2 times/week and consisted of sinusoidal oscillating magnetic fields of 120 Hz using a solenoid, with nominal field amplitude of approximately 0.6-0.8 mT (6-8 Gauss) RMS at the center of the stimulation system. The amount of blood exposed to the therapeutic ELF-MF using the forearm device is approximately 30 ml/min or 3.6 lt/session.

DEVICEThorax tissue exposure with ELF-MF

The treatment was delivered 25 minutes/day, 2 times/week and consisted of 120 Hz using a quasi-Helmholtz coil configuration, with nominal field amplitude of approximately 0.6-0.8 mT (6-8 Gauss) RMS at the center of the stimulation system. The amount of blood exposed to the therapeutic ELF-MF using the thorax device should be approximately 6,500 ml/min or 162.5 lt/session, which is approximately 45 times more blood volume stimulation per unit of time compared with the Forearm exposure system.

Design outcomes

Primary

MeasureTime frameDescription
Diabetic foot ulcer healing time14.2 weeks or upon complete ulcer healingHealing time was defined as the period (in days) required for the completion of ulcer closure when applying electromagnetic field treatment. Treatment period end-point was 14.2 weeks or upon complete healing according to clinical inspection.

Secondary

MeasureTime frameDescription
Adverse eventsTwo periods: 1 year and up to 7 yearsAfter treatment, follow-ups were performed to assess short-term (\<1 year) and long-term safety (up to 7 years) after treatment. Adverse events were also assessed and defined as: a) Ulcer recurrences in the same site, b) Damage to an organ, c) Development of cancer or any other disease states possibly associated to the use of Extremely Low Frequency Magnetic Fields treatment.
