Traumatic Brain Injury - Page 2
In the head figures where there is one location with no circle, the empty location represents the origin of a "flashlight" which "sends" out its beam to the other locations. When the beam arrives at a particular location a coherence value is calculated. The colors of the circle indicated the standard deviation (SD) difference from the normative reference group. The white color indicates that the subject was within the range between +.50 and -.50 standard deviations. The light blue indicates the subject was between -.50 and -1.50 SD. The dark blue indicates the subject's value was below -1.50 SD. Light orange indicates the subject was between +.50 SD and +1.50 SD while the dark orange indicates a value above +1.50 SD.
Comparisons across intervention programs for the TBI patient
The following figure presents the SD effect sizes of the different approaches to the cognitive problems of the TBI patient. The figures indicate a significant superiority of the QEEG activation biofeedback approach to these problems in brain functioning. The computer interventions typically involve working on a computer to improve attention and memory. The strategy intervention teaches the subject to visualize, organize the information presented or engage in other mnemonic aides to improve memory functioning. One of the drawbacks of this approach is that, although they can be successful short term, individuals have a tendency to stop using the strategies after a period of time.
