Disability
Disability was analyzed using the RMDQ, and showed improvements in all the groups. At the beginning of the study, the three groups were homogeneous (P = 0.15), but after the treatment, a difference between group 3 and the other two groups was found (P < 0.01). The decrease in RMDQ score was significant in groups 1 and 2 (Figure 6), and for the three groups (P < 0.01).
