The effect of mouth closure on drooling and speech.
The efficacy of a feeding program to decrease drooling and increase vocalizations by promoting mouth closure was explored in two boys with cerebral palsy through the use of oral facilitation techniques. A single-subject ABA design was repeated across subjects. Baseline 1 consisted of 5 (Subject 1) and 10 (Subject 2) half-hour sessions during which the subjects were fed applesauce and apple juice without treatment. A 1-hr play session followed, during which saliva was collected on an absorbent bib and weighted. Bilabial vocalizations produced by the subjects were recorded and counted. A 12-session intervention phase followed, which was identical to the baseline phase except that treatment was implemented. Treatment consisted of techniques to reduce tactile hypersensitivity before feeding and the application of jaw control during feeding. Baseline 2 consisted of 7 sessions identical to baseline 1. The results suggest that this intervention decreases drooling but does not increase bilabial vocalizations. Longer treatment and follow-up may be needed in future efficacy studies.

Effect of intermittent, supine cervical traction on the myoelectric activity of the upper trapezius muscle in subjects with neck pain.
This study was undertaken to compare the myoelectric activity of the upper trapezius muscle before, during, and after intermittent, supine cervical traction. Twelve people with diagnosed disease or injury of the cervical spine served as subjects. Electromyographic recordings were taken from the upper trapezius muscle with bipolar surface electrodes. The subjects were treated with 20 minutes of intermittent, cervical traction at a force of 8% of their body weight. Recordings were taken with the subjects in the supine position before the traction, during one pull and release phase of the 10th and 20th minutes of traction, and after completion of the traction treatment. An analysis of variance with repeated measures showed no significant differences in the myoelectrical activity during the six time periods measured. The results of this study do not support the clinical use of intermittent, supine traction to produce cervical muscle relaxation.
