¹Wilcoxon signed-rank test.

To examine the effects of HBT on other factors, we compared the questionnaire survey at baseline, 1 mo, and 2 mo. No statistically significant differences in the DHI including subcategories, HADS including subcategories, OD scores, Graybiel’s motion sickness scores, or PSQI at baseline were observed between the two groups. HBT: Hangebyakujutsutemmato; DHI: Dizziness handicap inventory; HADS: Hospital anxiety and depression scale; HADS-A: Hospital anxiety and depression scale-anxiety; HADS-D: Hospital anxiety and depression scale–depression subscale; OD: Orthostatic dysregulation; PSQI: Pittsburg sleep quality index.
