ostural Control and Muscle Tone. (Taken from Willard's evaluation):
Tests of postural function that assess muscle tone and antigravity postural
control proved challenging for Willard. He had significant difficulty with both
antigravity prone extension and supine flexion postures. [Willard was unable to
maintain an anti-gravity prone extension posture or a supine flexion posture.
[He
was able to assume both postures with facilitation, but could not maintain them
for more than a few seconds.] Difficulty with antigravity postures indicates
underlying low muscle tone and depressed vestibular processing.
Cocontraction, which is the ability to maintain muscle tension to stabilize a
joint against resistance, was also slightly diminished, again suggesting evidence
of depressed vestibular processing.
Low muscle tone was also noted to have an impact on Willard's fine motor skills.
Ligament laxity was observed. He tended to use his whole arm when coloring

eally, it sounds like Willard is a "floppy "kid. At the Spectrum Center we treat a lot of floppy kids. They are known, variously as SI Kids, Sensory Integration Dysfunction Kids, children with Sensory Integration Disorder, etc.

otor Planning, Praxis (More about Willard)
Tasks that require motor imitation are a measure of motor planning abilities.
Willard had a difficult time imitating gross motor postures. It was also
observed that Willard was very slow in his execution when attempting to imitate
motor postures. He had to think through each posture cognitively before his body
could execute the posture.
Willard also had a difficult time with tasks that required sequencing. When
asked to rapidly sequence movements of thumb to alternate fingers, it was
observed that Willard had accuracy in finger to thumb opposition. The evaluator
had to slow down the demonstration of the sequencing pattern in order for Willard
to successfully complete the task. He was eventually able to figure it out with
the help of cognitive reasoning. Motor planning abilities under lie sequencing
abilities and this appears to be an area with which, once again, Willard was
cognitively thinking through each movement and also visually watching his/her
thumb touch each finger.
Willard's responses were limited and concrete when asked to initiate the motor
plan for a novel behavior. For example, when asked to pretend how he would
hammer a nail into a piece of wood, rather than pretend to hold a hammer and a
nail, Willard turned his hand into a hammer and pounded it against the table.
