A pilot study was conducted using PEMF treatment on individuals with a history of TBI (time of traumatic insult ranged from several months to several years post-traumatic event). Individuals who had suffered mild, moderate, and severe TBI were recruited into the study, and these individuals all suffered from chronic symptoms of TBI.
- A battery of tests was administered with the Brain Gauge Pro both pre-treatment and during each patient’s subsequent clinical visit during the study.
The bar chart below is an overview of the composite test score (combines results of all tests administered) or “cortical metric” averaged across all the individuals in the study for 3 different time points. Note the Y axis is plotted on a scale of 0-100 (% of the normative range). Because the individuals responded to treatment at different rates, the times were averaged as pre-treatment (before the study started), “intermediate” (intermediate time points
determined by the patient’s first and last clinic visit), and “post treatment” (final treatment point for the individual).
- The overall cortical metrics score plotted demonstrates significant improvement in the patient’s overall brain health that occurred while PEMF therapy was being administered. The scores paralleled other outcome measures that were obtained in the study and also demonstrated improvement in CNS function.
- Additionally, patients reported qualitative improvements in brain health and cognitive function over the course of the study.
- Individual data points. Data from individuals in the study are displayed in the plots below. The first 4 patients had all experienced an mTBI event but were still symptomatic (although most individuals recover from a concussion, a significant percent become chronic and have difficulty recovering).
- Note that in each case, the individuals performed poorly pre-treatment and demonstrated significant improvement post-treatment (note: short red bars indicate scores that are well below the normative range; long green bars indicate scores in the normative range.

DEVICE: ICES Model A9a modified to run one frequency only: 10 Hz (5 pulses per second) continuously.
- This stimulation pattern is identical to Mode #1 on the ICES models A9 and P2
- COIL PLACEMENT (still under investigation, not yet optimized)
- The First Placement of the Coils was coiled on opposite sides, front and back of the head.
- The second Placement of Coils was on opposite sides of the head across the temples.
- Optional Placement of Coils was across the occipital lobes, side of the head, and coils on opposite sides of the head.
- Stimulation was two hours every day at approximately the same time every day, to accommodate the subject's schedule. The study continued for up to 3 months of daily use.
- All 8 subjects showed marked improvement within 6 weeks.
- Based on the study so far, the suggested treatment for any head injury, or multiple injuries is: one hour in First Placement, front and back of the head, followed by one hour in Second Placement, across the temples, coils on opposite sides of the head (2 hours total) every day, at approximately the same time every day.
- Begin with "L" (LOW) on Day 1
- If no adverse reaction, raise to "M" (MEDIUM) on Day 2
- If no adverse reaction, raise to "H" (HIGH) on Day 3 and keep it on HIGH for the remainder
- Most people had a headache for the first 2 to 3 days. None of them were disabling and none of them required medication, or medical attention, even the severe TBI people.
- Typically the treatments would be daytime or evening every day. Treatment continued for up to 3 months
