“…Deep core stabilisers such as transversus abdominus (TrA) have impaired timing patterns 1,7 and reduced activation levels 5 in individuals with CLBP. Additionally, there is evidence that patients with CLBP are less able to preferentially activate the deeper stabilisers relative to larger superficial muscles such as the rectus abdominus (RA) 2 .…”

IntroductionPreliminary evidence suggests that unstable footwear is beneficial for back pain. It has been proposed that the effect may be mediated by challenging balance, causing an increase in core stabilising muscle activity. However, no studies have investigated the effects of unstable footwear on core muscle activity. The primary aim of this study was to investigate if trunk muscle activation during quiet two-legged stance was affected by unstable footwear in comparison to usual footwear or on barefoot conditions. Materials and methodsIn this randomised repeated measures design, healthy participants (n = 21) stood on a Kistler™ force platform for 30 seconds three times under three conditions: (1) barefoot, (2) usual footwear and (3) unstable footwear. Under each condition, postural sway and the average intensity of electromyographic activity was collected for three different muscles bilaterally: transversus abdominus (TrA), external obliques (EO) and rectus abdominis (RA). Results A repeated measures ANOVA found increased postural sway (centre of pressure velocity) in the unstable footwear condition compared to both the barefoot (4.2 (1.7 -6.7) mm.s
