摘要

Many studies analysed the ability of blindfolded adults toperceive passive rotation and to orient themselves usingthe vestibular system. Ivanenko et al. (1997) imposed tositting blindfolded subjects CCW rotations (45°, 90°,135°, and 180°) using a motorised chair (Robuter). Theyhad to reproduce angles and the results showed angleoverestimation, even if the same authors recognised apossible bias that could affect the results, caused by theimposing rotation always in the same direction. Siegleret al. (2000) used the same device to impose CW andCCW rotations to healthy blindfolded subjects; theycompared the rotation directions and obtained no signifi-cant differences. Marlinsky (1999) rotated healthy blind-folded subjects by means of a manual turnable chair, atconstant angular velocity and amplitude from 30° to 360°,both CW and CCW directions. The subjects still overes-timated the passive turns; in reproduction, they overesti-mated small angles and underestimated the higher ones.Thus, a heterometric space was drawn, depending on the turn magnitude and direction. However, no statisticallysignificant differences were determined between rotationdirections both in perception and reproduction. Also in thepaper by Okada et al. (1999), sitting subjects were rotatedCW and CCW and the results were normalised for direc-tion, because no asymmetries were observed. In otherresearches, a motorised turnable platform was used toimpose CW and CCW rotations to blindfolded standingsubjects (Jiirgens et al. 1999; Becker et al. 2000); no sig-nificant difference between directions was noted. Finally,Metcalfe and Gresty (1992) compared perception ofCW/CCW passive rotations, imposed by the Barany chair,in normal and vestibular subjects. Comparing directions, itwas found that healthy subjects had the same ability inboth hemispaces, while vestibular patients showed moredifficulties towards the affected side.
