Control Group

This study investigated the effect of EMG biofeedback training in reducing muscle tension among subjects who displayed Type A behavior. 22 Type A college students (19 to 22 yr. old) were randomly assigned to either a biofeedback group or a control group. After 6 wk. of training, Type A subjects showed a significant reduction in muscle tension for both resting and aroused states; however, the reduction of muscle tension did not result in reduction of Type A behavior patterns.

Cursive Handwriting

The effects of EMG biofeedback training on cursive handwriting were investigated for 4 girls and 5 boys in Grade 4. A significant reduction in EMG between the first baseline session and the last training session was obtained. Four of 5 characteristics of handwriting improved significantly. The need for carefully designed research comparing EMG biofeedback training and relaxation training was indicated. A self-control factor in handwriting was hypothesized.

Relaxation Procedure

The present study investigated the effects of a trainer's presence vs a trainer's absence on subject-controlled, response-contingent relaxation training. Ten college students each received either frontalis EMG biofeedback training with trainer present, biofeedback training with trainer absent or information/placebo control with a trainer present. The relaxation procedure included a .5-hr baseline session and five .5-hr. training sessions. Analysis indicated that the biofeedback groups showed greater within-session reduction of EMG activity than the control condition but did not differ from each other. Post-session EMG levels across training sessions showed a significant decrease for all three groups. However, the two biofeedback groups relaxed more across sessions than did the control group and the two biofeedback groups did not differ from each other. Subjective ratings showed that subjects in all conditions became more relaxed both within and across sessions. The results indicate that a trainer's presence is not crucial in facilitating subject-controlled, response-contingent relaxation training.

Carry Over

In this case study, a geriatric patient who had an 18-year history of hemifacial spasm was given EMG-biofeedback-assisted relaxation training. No formal speech therapy was provided. Our results confirmed two hypotheses: (a) The patient would learn to reduce frontalis EMG and facial spasm with and then without biofeedback, and (b) as a result, speech would be markedly improved. At both the 1-month and 15-month follow-up the patient retained the ability to relax his facial muscles with similar carry-over to speech. Possible neurophysiologic mechanisms of action mediating the feedback training are discussed.

The present article provides a case study showing the application of neurofeedback and biofeedback training with heart rate variability (HRV) training to a 27-year-old man, Mike, who suffered a severe traumatic brain injury (TBI) in a motor vehicle accident. The study demonstrates the use of single-site neurofeedback training, metacognitive strategies, and low-resolution brain electromagnetic tomography (LORETA) z-score training along with HRV. A review of the initial assessment and subsequent progress updates included an examination of continuous performance tests such as test of variables of attention, integrated visual and auditory continuous performance test, and single-channel electroencephalography results, HRV statistics, and 19-channel quantitative electroencephalogram results. The client demonstrated significant improvements on all measures posttraining with marked improvement in five areas: memory, sleep and energy level, academics, mood and irritability, and mental sharpness. Working with clients such as Mike supports the view that one- and two-channel neurofeedback and LORETA z-score neurofeedback, combined with HRV training, are promising interventions for clients with TBIs.
