Hospital Anxiety and Depression Scale (HADS) and Dizziness Handicap Inventory (DHI). Median scores and interquartile range (IQR) for the DHI for physical, emotional, and functional subgroups and the HADS)for anxiety and depression. Total scores of the DHI and DHI differ significantly comparing athletes with sports-related concussion (SRC) with controls, p < 0.001 and p < 0.001. The significance threshold was set to 0.05; significant values are bolded.
