title: Factors contributing to variability of caloric test scores.
abstract: Data were analyzed from 30 healthy male subjects, examined on three successive days with caloric, rotatory, optokinetic, gait and posture tests. Data were also analyzed from 11 additional test sessions performed on 10 of these subjects. A short-acting caloric test was used and nystagmus intensity was measured by means of an interactive computerized technique. Large inter-individual differences were noted for all test results and these differences remained consistent as tests were repeated. Factors which may contribute to inter- and intra-subject variability of caloric test scores are identified and discussed.
