神奈川県における児童および生徒の平衡機能の調査 Ｖ

Abstract

Several screening equilibration tests were carried out in 238 pupils of the first up to the sixth grade in a primary school in Hiratsuka city (Kanagawa prefecture). The examinations included the one foot standing test in forward tilted posture with eyes open, the walking test with eyes closed, the twice step-rotating test with eyes closed, the rail-walking test and the balance board test with eyes open, which were reported in our previous papers.The subjects, whose results did not fit the standard values in one or more of the tests and the subjects with idiopathic scoliosis were 76 (31.9%) out of 238 pupils. They were re-examined by other selective tests, such as the blinded-folded vertical writing test, the stepping test with eyes closed, the statokinesimetry in standing erect with eyes closed, spontaneous, positional and positioning nystagmus tests under Frenzel's glasses and the tympanometry.In the vertical writing test 44. 7% of the cases showed the deviated writing of above 10 degrees and 66. 2% of them showed the areas of more than 14.8 cm2 in statokinesigrams. On the contrary, the results of stepping test remained within normal limits in all of them.Positional nystagmus was observed in two cases. Tympanogram of type B or C was obtained in 28.9% of the cases. Relationships between the results of the paired tests including the other factors, for example, Rohrer's index and the scores in gymnastic and in learning, were sta-tistically examined.Contrary to our expectation, any significant correlation of the results between in the screen-ing tests and in the selective ones could not be found.Reverse correlation was noticed in the following paired test results: Rohrer's index and gymnastic, and Rohrer's index and the one foot standing test in forward tilted posture. Positive correlation was observed in the scores of gymnastic and learning. These results resemble those obtained in our previous studies.
