Purpose. The aim of this research was to increase our understanding of motor development during early childhood by examining measures of motor control in the oral/speech and manual systems of typically developing preschool children. Measures of strength, rate, muscle release times, force establishment, and force stability were examined to determine which motor control processes developed similarly across effector systems and which processes followed system specific developmental trajectories.

520 $a Purpose. The aim of this research was to increase our understanding of motor development during early childhood by examining measures of motor control in the oral/speech and manual systems of typically developing preschool children. Measures of strength, rate, muscle release times, force establishment, and force stability were examined to determine which motor control processes developed similarly across effector systems and which processes followed system specific developmental trajectories.
520 $a Methods. Fifty typically developing preschool children, 10 in each of the following age groups 3;0--3;5, 3;6--3;11, 4;0--4;5, 4;6--4;11, and 5;0--5;5, were tested over two sessions. Strength measures included dominant and non-dominant power grip maximum volitional contraction (MVC), oral closure measured at the tongue (OC-tongue) MVC, maximum phonation, and maximum exhalation duration. Muscle release rates were determined for power grip, precision grip, and for the tongue/jaw muscles. Maximum voluntary rate measures included single and tri-syllable repetitions, finger to thumb tapping, and finger sequencing. Speech rate was measured by maximum syllable rate in conversation. Measures of force regulation included initial overshoot and variability during a three-second ramp and hold task.
520 $a Results. Children increased similarly in measures of strength and voluntary movement rates across systems during the preschool years. Muscle release rates and variability in force regulation decreased for the manual system only. The initial overshoot, evidenced when establishing a target force level during a force regulation task, decreased with maturity. There was no change in maximum syllable rate during conversation between the ages of three and five. The children with increased grip strength, relative to the other children, showed faster movement rates, faster muscle release times, increased force stability, and decreased initial overshoots. The children with increased OC-tongue strength, relative to the other children, showed increased rate on two of the nine syllable repetition rate tasks, faster muscle release times, decreased force stability, and decreased initial overshoots.
520 $a Conclusion. During the preschool years, strength, rate, and the ability to inhibit force acceleration appear to develop holistically. Muscle release times and regulation of force stability are system specific.
