The mean DPA-FM treatment time was 10.8±1.88 months. The hand-wrist growth and developmental stages were MP3u or Ru at T3. The mean follow-up period was 5.0±1.98 years. Friedman’s Two-Way ANOVA and Wilcoxon signed-rank tests were used to evaluate the treatment (T2-T1), follow-up (T3-T2) and overall (T3-T1) results. </span> <b> <span lang="en-us" style="font-size:12pt;font-family:Helvetica, ’sans-serif’;" xml:lang="en-us"> </span> </b> </p> <p> <b> </b> </p> <b> </b> <p class="MsoNormal" style="margin-bottom:.0001pt;text-align:justify;line-height:normal;"> <b> <span lang="en-us" style="font-size:12pt;font-family:Helvetica, ’sans-serif’;" xml:lang="en-us">Results: </span> </b> <span lang="en-us" style="font-size:12pt;font-family:Helvetica, ’sans-serif’;" xml:lang="en-us">With the DPA-FM therapy, SNA and ANB angles increased (p<0.001); however, no significant differences were found in these parameters during T3-T2 period [p=0.655 (SNA), p=0.805 (ANB)].
