Fig. 3. The Roles and Maudsley score at the baseline and 1-, 4-, 12-week follow-ups after the extracorporeal shock wave therapy, in both groups. This figure shows significant improvement for both group in the Roles and Maudsley score over the entire period (^***p<0.001 for time effect, ^***p<0.05 for group-time interaction) and significant differences between the two groups at 1 week and 4 weeks (^*p<0.05). Group M, medium-energy (0.093 mJ/mm²) group; group L, low-energy (0.040 mJ/mm²) group.
