We previously reported that orthostatic dysregulation (OD) was relatively common in normal young females and that the Schellong test was a useful, practical procedure in the diagnosis of this condition.
We carried out a survey and analyzed date from both the Yatabe-Guiford Personality test (Y-G test) and the Cornell Medical Index-Health Questionnaire (CMI) in 167 females aged 18 to 24 years (mean age =19.7 years). OD was confirmed in 38 and suspected in 32; the remaining 97 were considered to be normal from the results of the Questionnaire for OD.
Of the 167 young females, 33 (19.8%) were type A in the Y-G test, 38 were type B (22.8%), 27 type C (16.1%), 52 type D (31.1%) and 17 type E (10.2%). Reports in the literature indicate that individuals with type B and type E Y-G results are apt to have mental and/or emotional “instability”. Of the 97 normal subjects, 28 were type B or type E (28.8%), of those with confirmed OD the number was 17 (44.7%) and of those with suspected OD it was 10 (31.2%). The difference between the normal subjects and those with confirmed OD was significant. Of 132 individuals with CMI types I and II 34 (25.8%) were Y-G types B and E and of 35 individuals with CMI type III and IV 21 (60%) were Y-G types B and E.
These results suggest that there may be some correlation between OD and emotional and/or psychosomatic instability. Further studies on the practical implications of these testing procedures are necessary for the evaluation of individuals with OD.
