ABSTRACT

PURPOSE: This study aimed to identify differences in the thickness of the transverse abdominis (TrA) and pelvic floor muscles (PFM) between those with (LBP) and without low back pain (non-LBP). The standardized methods of contraction for the TrA and PFM were used to perform the abdominal draw-in maneuver (ADIM) and pelvic floor muscle contraction (PFC), respectively. METHODS: This study included 27 young men and women, who were verbally instructed regarding the maneuvers (LBP, n=14; non-LBP, n=13). For all subjects, TrA and PFM thickness were evaluated by ultrasonography during ADIM and PFC. RESULTS: The results of this study showed that TrAthickness increased during ADIM and PFC to a greater degree in the non-LBP group than in the LBP group (p < 0.01). PFM thickness increased more during PFC in the non-LBP group than in the LBP group (p < 0.05). Both groups showed greater increases in TrA thickness during ADIM than during PFC (p < 0.01), and greater increases in PFM thickness during PFC than during ADIM (p < 0.05). CONCLUSION: These results suggest that receiving verbal instructions on how to use each muscle for a specific maneuver was more beneficial than other verbal instruction. Further studies are needed determine how our results may be applied beneficially in research on this topic.
