Improvement in abdominal motion ( RC/ABD ratio) after
DBTP was inversely related to the baseline RC/ABD ratio
(r– 0.8; P.001) and baseline diaphragmatic mobility
(r.58; P.02) (fig 5). The bottom right area in figure 5A
reveals that most patients who improved their abdominal motion
had a baseline predominance of costal breathing (RC/ABD
ratio 0.5). Figure 5B reveals that patients with a lower
baseline diaphragmatic mobility demonstrated a higher improvement
in abdominal motion after DBTP. Changes in abdominal
motion did not correlate with any other baseline outcomes
in the TG. The RC/ABD ratio after a 4-week
follow-up period was not related to the baseline RC/ABD ratio
or baseline diaphragmatic mobility in the CG (P.05).
