Rotational testing is more sensitive than caloric testing even though both are typically used during a full balance assessment. Rotational testing produces fewer false negatives than caloric testing and is the only test suitable for compensated unilateral lesions and bilateral vestibular lesions. Rotational testing also avoids all the accessories required for caloric testing and is therefore preferred by many patients. Some patient groups (e.g. children) will often accept rotational testing but reject calorics.
