VESTIBULAR FUNCTION AND MOTOR PROFICIENCY OF CHILDREN WITH IMPAIRED HEARING, OR WITH LEARNING DISABILITY AND MOTOR IMPAIRMENTS

Vestibular status and motor proficiency of 30 hearing‐impaired and 15 motor‐impaired learning‐disabled children were documented to determine whether vestibular loss can account for deficits in motor co‐ordination. Vestibular loss was differentiated from sensory organization deficits by means of VOR and postural orientation test results, which were compared with those of 54 normal seven‐to 12‐year‐olds. Reduced or absent vestibular function in 20 hearing‐impaired children did not affect development of motor proficiency, except in specific balance activities. However, sensory organization deficits in the learning‐disabled group and in three of the hearing‐impaired children were associated with widespread deficits in motor proficiency.
