8. Fig 7
Changes in the latency response measured from right transversus abdominis and internal oblique muscles for the shoulder flexion task. A significant time effect was identified from the repeated-measures ANOVA from 16 to 56 weeks only. No group effects were identified from the analysis. ANCOVA and correlation analysis found that subjects with higher baseline latency times had the greater improvements during the intervention.
