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 TrA thickness increased during ADIM and PFC to a greater degree in the non-LBP group than in the LBP group (p |
