Predictors of success in the EMG biofeedback training of hyperactive male children.

EMG biofeedback training is continuing to evolve as a promising treatment of hyperactivity. But while research on its application suggests that this technique induces significantly lower EMG levels in experimental samples as a whole, it also discloses that some children evidence but limited reductions. Most likely, this variability is introduced by differences in subject attributes. This study assessed that prospect by examining whether four common subject characteristics correlated with the extent of decrease in EMG level achieved by 59 hyperactive school-aged boys. Those variables were pretreatment EMG level, age degree of hyperactivity, and locus of control. Number of applications or training sessions was included as the fifth predictor. A multiple regression analysis determined that only locus of control was predictive of success in EMG training; however, it accounted for 72% of the variance. Implications of these findings are discussed.

The effects of EMG-assisted relaxation training on the academic performance, locus of control, and self-esteem of hyperactive boys.

This study investigated effects of EMG-assisted relaxation training on the academic performance, locus of control, and self-esteem of hyperactive junior high school-age boys. Twenty-four subjects each were randomly assigned to the treatment and control condition. Treatment consisted of six 20 to 25-minute sessions conducted biweekly. Pretreatment frontalis EMG, math, reading, and language performance, locus of control, and self-esteem were assessed for both groups. Outcome measures were again obtained on these dependent variables 2 weeks after the last treatment session. Experimental subjects demonstrated significantly higher posttreatment reading and language performance. Math performance gain did not reach statistical significance. A significant internal shift in locus of control was observed; however, self-esteem did not improve to that level. These outcomes correlated with significantly lower posttreatment frontalis EMG in the experimental group. EMG level did not change during the course of this study for control subjects. Implications of these findings are discussed in terms of existent research.

Biofeedback-induced relaxation training as an alternative for the elementary school learning-disabled child.

This study examined the effects of biofeedback-induced relaxation training on attention to task, impulsivity, and locus of control among 32 learning-disabled children between the ages of 8 and 11 years. Attention to task and impulsivity were measured by the Matching Familiar Figures Test and locus of control was measured by the Nowicki-Strickland Scale. Participants were randomly assigned to experimental (N = 16) and control (N = 16) groups. The study spanned a total of 8 weeks, with the experimental treatment consisting of three sessions spaced approximately 2 weeks apart. The treatment included EMG biofeedback training used with relaxation tapes. Univariate F values and discriminant analysis procedures revealed that the attention to task and impulsivity measures proved to be valid discriminators, respectively beyond the .01 and .05 levels of significance. Experimental group subjects had significantly fewer number of errors on the attention to task measure and significantly lower impulsivity scores. It was concluded that the biofeedback-induced relaxation training affords promise in assisting learning-disabled children in reaching their education potentials. It was recommended that future research examine the long-term efficacy and the transfer to school-related tasks of this intervention.
