Theta Burst 20 Hz
TMS is highly desirable over ECT (Electroconvulsive Therapy or “Shock Therapy”) as ECT treatment requires general anesthesia, is usually accompanied by long-term side effects such as memory loss, and costs significantly more. However, conventional TMS falls short in matching the remission rates demonstrated with ECT treatment.
Theta burst stimulation, a patterned form of TMS administered as pulse triplets typically at a frequency of 50 Hz (50 pulses per second), has consistently produced longer lasting results than conventional TMS with fewer side effects. Dr. Stubbeman has further enhanced this robust form of TMS by applying a novel Theta Burst 20 Hz (20 pulses per second) protocol to improve clinical effectiveness, as visualized in the two graphs at right. On average, only one out of three of patients will completely recover from their depression after treatment with conventional or deep TMS, whereas more than two out of three patients completely recover after treatment with Theta Burst 20 Hz TMS. The efficacy and proven superior safety of Theta Burst 20 Hz TMS treatment make it the optimal treatment choice for patients who cannot take medication or who have failed other types of treatments for depression.

Dr. Stubbeman utilizes neuronavigated TMS, a precision targeting system which results in the most effective form of TMS treatment (Langguth et al., 2010). A patient’s digital MRI scan is used to create a 3D image of the brain. Next, the patient’s head is spatially correlated with the newly created 3D brain image using a series of reference points. An infrared camera then tracks these positions in order to represent the patient’s head relative to the TMS treatment coil, allowing the clinician to visualize in real-time where on the brain the electromagnetic pulses are delivered.

Quantitative Electroencephalography (QEEG)
Dr. Stubbeman administers quantitative electroencephalography (QEEG), which is used to measure electrical patterns on the scalp that reflect brain activity. Not only are the brain waves recorded, but their sources are also overlaid onto the patient’s MRI using a method called swLORETA. This essentially quantifies the intensity of a patient’s tinnitus (Ashton et al., 2007).
