Effect of intervention
Dizziness, Visual Vertigo
We observed a significant main effect of time for 4 outcome measures (Fig. 
Pre and Post estimated marginal mean and their respective 95% confidence intervals for the traditional and C.S.I groups on outcomes that showed a significant change over time in both groups: The Dizziness Handicap Inventory (DHI pre: Traditional 50.8 [41.1, 60.49], C.S.I 53.07 [43.37, 62.76]. post: Traditional 24 [12.11, 35.89], C.S.I 42.4 [29.15, 55.77]); Functional Gait Analysis (FGA pre: Traditional 21.07 [19.05, 23.08], C.S.I 20.43 [18.34, 22.52]. post: Traditional 27.95 [25.5, 30.41], C.S.I 26.35 [23.61,29.1]); Activities Specific Balance Confidence Scale (ABC pre: Traditional 74.21% [64.39, 84.03], C.S.I 71.34% [61.52, 81.16]. post: Traditional 79.78% [68.41, 91.14], C.S.I 82.89% [70.46, 95.31]); Visual Vertigo Analog Scale (VVAS, pre: Traditional 36.84 [24.72, 48.97], C.S.I 43.05 [30.93, 55.17]. post: Traditional 21.41 [6.51, 36.31], C.S.I 31.28 [14.59, 47.97])
Pre and Post estimated marginal mean and their respective 95% confidence intervals for the for the traditional and C.S.I groups on outcomes that did not change over time in either group: Timed-Up and Go (TUG, pre: Traditional: 7.77 s [6.87, 8.67], C.S.I: 7.97 s [7.02, 8.92], post: Traditional: 8.03 s [7.08, 8.98], C.S.I: 7.93 s [6.88, 8.98]); The Four-Step Square Test (FSST pre: Traditional 9.48 s [7.52, 11.44], C.S.I 11.49 s [9.43, 13.55 ] post: Traditional 9.65 s [7.54, 11.75], C.S.I 10.29 s [7.96, 12.63])
