It is well known that the caloric test is one of vertigo investigations in adult population. Is it the same for assessing a dizzy pediatric patient?
Sue Snashall, amongst others, has published on caloric tests in children.
Thanks Anthony for your sharing. Would you provide me with this published article.
Here is one abstract:
Vestibular function tests in children.
S E Snashall
Vestibular function tests were performed on a series of 57 children between the ages of 1 and 16 years. Inattention and immaturity of eye movement control created difficulties in the analysis of the electronystagmography traces in some instances. With the eyes closed, spontaneous and positional nystagmus occurred in 20% of asymptomatic children and this was thought to be physiological. Changes in external ear pressure (fistula test) enhanced this spontaneous nystagmus. Smooth pursuit ataxia and optokinetic abnormalities were common in the children with reading disabilities and those with congenital deafness, and were thought to be soft neurological signs of brainstem dysfunction. The torsion swing chair test was acceptable and gave easily readable responses. Caloric abnormalities were very common in children with reading disabilities and provided useful information in those with congenital and acquired disorders of hearing and balance. It was concluded that normal data were required for children of all ages in order to improve our understanding of electronystagmography in children.
Thanks so much Anthony for the article. Is it tolerated by children undergoing caloric test.
