Follow-up of square drawing test in vestibular neuronitis.

The square drawing test (SDT) devised by Sekitani (1975), which is a modification of Fukuda's vertical writing test, was performed to evaluate vestibular dysfunction in 15 patients with vestibular neuronitis followed up for a long period. In particular, two parameters (distance and total length) were analyzed in the present study. Distance was analyzed by dividing the 15 cases into 3 groups. The largest group showed a tendency to shorten at an early stage. Total length was examined by dividing the 15 cases into 3 groups. The largest group showed a tendency towards macrographism at an early stage. It was found that as the degree of caloric responses recovered, the range of distance and total length decreased. Considering the correlation between parameters of the SDT (distance and total length) and caloric responses we concluded that the SDT is a feasible method to evaluate and follow up patients with vestibular dysfunction.
