ResumoThe study investigated the effect of interrupted music/silence and interrupted music/tone on the head posturing of persons having cerebral palsy. Twelve subjects clinically diagnosed as spastic cerebral palsied and ranging in age from 3 to 37 years participated in the study. An individual subject design (ABAC) consisted of two baseline conditions and two treatment conditions: (a) interrupted music/silence; and (b) interrupted music/tone. Each subject wore a special head device containing a series of mercury switches which activated the music/tone contingencies. This apparatus also monitored erect head position, the number of seconds during which the head was improperly postured, and the number of times the head changed position. During the interrupted music/silence condition, recorded music was contingent upon erect head position. When the head became tilted 20° or more, the music ceased and was replaced with silence. When the head was improperly positioned during the music/tone condition, a 493 Hz tone automatically sounded until the head again was erected; at this time, the music stimulus resumed. Results indicated that head control improved during the treatment conditions for four subjects. One subject seemed to respond only to the music/tone condition, and the remaining subjects showed minimal improvement in head posturing throughout the experimental conditions. Individual results and recommendations for clinical applications are included.
