Table 2.

Changes in TWSTRS subscores and PNRS between T1 and T2 in patients who completed the study (n = 15).

Score (T1–T2 difference)	Mean ± SD [range]	Median [IQR]	p (raw)	p (adjusted)*
TWSTRS-Severity	2.07 ± 3.58 [−3.0–10.0]	2.0 [4.0]	0.046	0.182
TWSTRS-Disability	0.20 ± 4.48 [−8.0–9.0]	0.0 [5.5]	0.752	1.000
TWSTRS-Pain	1.15 ± 3.67 [−4.5–6.75]	1.5 [5.1]	0.248	0.744
PNRS	0.1 ± 2.7 [−5.0–5.0]	0 [3.5]	0.850	1.000

PNRS, Pain Numeric Rating Scale; TWSTRS, Toronto Western Spasmodic Torticollis Rating Scale; IQR, interquartile range. Values are T1–T2 differences; positive values indicate improvement (score decrease) and negative values indicate worsening (score increase). *p (adjusted) uses the Holm-Bonferroni correction across the four comparisons in this table. TWSTRS Severity showed a nominal improvement (raw p = 0.046) that did not remain statistically significant after correction for multiple comparisons (adjusted p = 0.182); none of the changes in this table reached statistical significance after correction.
