A school-age child has a profound hearing impairment. The child demonstrates normal postural reactions for walking, running in place, and skipping, but is unable to maintain balance when moving in various directions on a platform swing. What conclusion can the OTR make based on these observations?
A) Conflicting sensory input is inhibiting appropriate vestibular reactions.
B) Low muscle tone prevents the child from responding to transitional movements.
C) Persistent primitive reflexes are interfering with transitional movement patterns.
D) The child lacks anticipatory control required for higher-level motor skills.
