Figure 1 Schematic diagram of postural correction training. A: Supine position with knee joint suspension; B: Lateral decubitus position with knee joint suspension; C: Prone position with knee joint suspension; D: Supine position with ankle joint suspension; E: Lateral decubitus position with ankle joint suspension; F: Prone position with ankle joint suspension.

Figure 2 Graph of trend in changes of visual analog scale scores in the two groups. ^aP < 0.05, within-group vs pre-intervention; ^bP < 0.05, within-group vs 14 days of intervention; ^cP < 0.05, between-group comparison at the same time point. VAS: Visual analog scale.
