It is known that back pain can result in neurological imbalances , mainly affecting the deep muscles of the trunk and paraspinal , multifidus and transversus abdominis ( LINDGREN et al . , 1993; HIDES ; Richardson , Jull , 1996; HODGES ; Richardson , Jull , 1996). We observe a reduction in these shooting action potential and changes in motor control , represented by weakness, atrophy and reduced functional capacity ( HODGES ; MOSELEY , 2003; MACDONALD ; MOSELEY ; HODGES , 2006; RENKAWITZ ; BOLUKI ; Grifka , 2006 , RICHARDSON ; HODGES ; HIDES , 2004; BARR ; GRIGGS ; Cadby , 2007) .
