In the initial assessment and discussion of the symptoms, a brain map will be created using the clients EEG (brainwaves) response. The session includes the client sitting in a comfortable chair in a quiet room. One or two brain mapping processes will be used; qEEG mapping (Figure 1) or LENS mapping (Figure 2). The qEEG assessment involves the client wearing a cap, similar to a swimmer’s cap, which sends EEG data to the computer and is processed into a summary of the brain performance. A LENS data map uses a single sensor that is subsequently moved around the head to collect data which processed into a site sorting report for the next series of treatments. This session will take approximately one hour.

The next session will include a thorough review of the EEG analysis and the individual training plan for the client; then the sessions begin. During each 15-45 minute session, the client will be asked to give a “check-in” regarding their mental and physical status. He or she will then have one or more different types of neurotherapy applied. The system used will depend on their previous session response, their current functioning and/or on the training plan.
If the LENS system is used, it is likely that 1 to 21 sensors may be placed on the scalp one or two at a time; the number of sensors will be determined by the therapy chosen for each individual client at that time. The sensor will be moved from site to site by the therapist in an order determined by the clients brain map. The EEG brain activity may be seen on the computer screen during this procedure.
The NeuroField technology is used often on the body, as well as the head, and in combination with the LENS system. The NeuroField system allows for pulsating electromagnetic frequencies (pEMF), transcranial direct or alternating current stimulation (tDCS/tACS/tRNS) or real-time Z-score training (RTZ) for the individual. This is a dynamic technology that offers various methods for relief. Any or all of these devices can be used alone or together and the placement and features of the components (Figure 3 – NeuroField pEMF) will be determined by the individual’s needs. It is possible to have 4 sensors, 8 coils/paddles and the qEEG cap on the client in one session and providing therapy all at the same time

Some feedback systems allow the client to see and hear what is happening in their bio-electrical system. For example, if the client is having Z score training and they are watching a movie, the movie will run smoothly when their brain is moving toward the goal (Figure 4). However, when they lose focus, the movie or video will fade out and the sound will modulate. The system works similarly when playing games, such as Brain-man (Pac-man like). The goal is to motivate the brain with positive audio and visual reinforcement toward a more balanced state. Once the optimized profile is established and several sessions have been completed, the client may see subtle to dramatic behavioral changes.
You can think of EEG neurofeedback as exercise for the brain. Therefore, the body has used energy reserves during the session. Every client is asked to drink water and eat protein as soon as possible after the session to help refuel the body. We suggest the client pay close attention to their bodies and behavior in the hours and days immediately after the session. Most often, the clients feel only subtle, gradual changes, but can also experience brief tiredness, a feeling of being “wired” or irritated. All of this is feedback is shared with the therapist to help fine tune the treatment plan.
EEG Biofeedback is a learning strategy that enables clients to alter their brain waves. Different types of systems are used to pick up brainwaves, similar to the way a stethoscope picks up a heartbeat, then information is given to the client to make subtle changes through protocols designed by the clinician. When information about a person’s own brain wave characteristics are made available to them, they can learn to change them.
EEG Biofeedback is used for many conditions and disabilities in which the brain is not working optimally.
