The main outcome was the percentage of subjects whose MAS score decreased by at least one grade after treatment. The TTM group had a higher percentage of subjects whose spasticity improved by at least one grade than the PT group in both types of analysis (70.8% versus 61.9% in PP analysis; 70.8% versus 50.0% in ITT analysis). However, there was no statistically significant difference between the two groups, regardless of whether it was analyzed by PP analysis (P=0.286) or ITT analysis (P=0.058) in muscles with maximal grade (Tables 2 and 3, respectively).
Figure 2 shows that, for secondary outcomes, BI scores increased significantly at Week 6 compared with baseline in both groups (P=0.008 and P=0.025 in TTM and PT groups, respectively), but no difference was found between the groups (P=0.805). Figure 3 illustrates the psychological aspects; anxiety scores in the TTM group had decreased at Week 6 compared with baseline scores (P=0.083), while the anxiety scores in the PT group had increased at Week 6 (P=0.624). However, there was no difference in the scores when the two groups were compared (P=0.144). Figure 4 shows the depression scores after treatment. The depression scores in the TTM group had decreased at Week 6 compared with baseline scores but were not significantly
