* \(p\)-value obtained using Wilcoxon signed-rank test; statistically significant at \(p<0.05\), ns = non-significant. **L-STIFF** = Lower limb-stiff. 1\(P1\) = \(p\)-value comparing L-STIFF at base assessments (T0) between paretic legs and non-paretic legs. 2\(P2\) = \(p\)-value comparing L-STIFF at one-month follow-up (T1) between paretic legs and non-paretic legs. 3\(P3\) = \(p\)-value comparing L-STIFF of paretic legs at T0 and T1. \({}^{\circ}\)P4 = \(p\)-value comparing L-STIFF of non-paretic legs at T0 and T1. \({}^{\circ}\)Ext. = Extension. \({}^{\circ}\) Flex. = Flexion.

Table 2: Mean and standard deviation (SD) of the L-STIFF measures (Nm/\({}^{\circ}\)) for paretic and non-paretic limbs at basal assessments (T0) and one-month follow-up (T1). knee extension at 30\({}^{\circ}\)/s and 60\({}^{\circ}\)/s, and knee flexion at 30\({}^{\circ}\)/s and 60\({}^{\circ}\)/s and the stiffness values were greater for hip extension at 45\({}^{\circ}\)/s, for hip flexion at 45\({}^{\circ}\)/s and 90\({}^{\circ}\)/s, knee extension at 120\({}^{\circ}\)/s, and knee flexion at 120\({}^{\circ}\)/s but these value differences were not statistically significant.
