Hip Ext Torque	0.11 (0.07, 0.21)	0.16 (0.12, 0.38)	0.06 (−0.01, 0.10)	0.1309
Knee Ext Torque	0.43 (0.37, 0.62)	0.68 (0.37, 0.75)	0.06 (−0.03, 0.24)	0.3223
TUG (s)	7.61 ± 1.70	6.63 ± 1.36	− 0.98 ± 0.84	0.0052
Pre-TUG Pain (0–10)	2.00 (0.00, 4.00)	0 (0, 3)	− 1 (−3, 0)	0.1719
Post-TUG Pain (0–10)	2.00 (1.00, 4.00)	0 (0, 3)	− 2 (−3, 0)	0.1250

Data are expressed as median (IQR) except for TUG which is expressed as mean ± SD. Values in italics indicate significant change at the 0.05 significance level in the exploratory analyses (Wilcoxon Signed Rank test [median {IQR} results] or paired t test [mean ± SD] results)
