“…It has been shown that regulation of balance is attention demanding, even in highly skilled individuals such as dancers [21]. We tested the effect of an attention demanding cognitive activity on postural fluctuations in a group of children with a mild form of ASD, using a word memorization task [21,22]. If individuals with ASD employ excessive cognitive resources to regulate their balance, then cognitive dual-tasking should have a destabilizing effect on this group but not on controls.…”

“…Related to Borg and Laxaback (2010) further research activities are necessary to identify the correct physiological interpretation of SE. SE was used in many studies of balance where different interpretations of it may be found (Cavanaugh, Mercer, & Stergiou, 2007;Deffeyes et al, 2009;Donker, Roerdink, Greven, & Beek, 2007;Duarte & Sternad, 2008;Haran & Keshner, 2008;Santarcangelo et al, 2009;Schmit, Regis, & Riley, 2005;Stins, Michielsen, Roerdink, & Beek, 2009). …”

“…In the context of balance, lower sample entropy values calculated from CoP motion (i.e. more regular sway fluctuations) have been related to a decrease in the effectiveness of postural control in people recovering from stroke (Roerdink et al 2006), children with cerebral palsy (Donker et al 2008) and dancers with eyes closed (Pérez et al 2014, Stins et al 2009). It is also argued that entropy values are indicative of the amount of attention given to balance control and that lower sample entropy values (synonymous with more regular sway fluctuations), are related to increased cognitive involvement in postural control i.e.…”

“…2004). Balance is a critical element of classical ballet and there have been several studies on postural control in dancers which suggest that dancers are better able to maintain balance in challenging conditions (Crotts et al 1996) and are more stable than non-dancers (Golomer et al 1999a, Golomer and Dupui 2000, Stins et al 2009), although some authors report that difference in postural control between dancers and non-dancers is task dependant (Hugel et al 1999, Pérez et al 2014, Perrin et al 2002, Simmons 2005b. Despite the importance of balance skills in classical ballet and the association between LBP and altered balance control there is limited information about the effect of LBP on balance in dancers and contradictory observations about the difference between dancers and non-dancers.…”

Physiology and pathophysiology of low back pain in ballet dancers

Classical ballet dancers combine artistry and physical skills to perform graceful and exciting movements. Lengthy, exacting dance training potentially promotes unique adaptation of motor control to; execute these movements; maintain optimal physiological function, and provide stability to avoid injury and pain. Yet low back pain (LBP) is common in dancers. Differences in motor control are frequently observed between non-dancers with and without LBP. This often involves reduced and delayed activity of deep trunk muscles and augmented activity of superficial muscles. These changes are proposed to affect the control of movement and stiffness of the trunk. LBP is also associated with deficits in postural control, an aspect of motor control, which depends on control of the trunk. Some features of adaptation in motor control are relatively common; but there are some features that are specific to individuals or different populations. It is essential to understand how motor control is adapted in elite classical ballet dancers with LBP as less optimal motor control has potential to impair performance and limit the capacity to dance. The overall objective of this thesis was to investigate aspects of motor control in dancers with and without LBP, with specific attention to trunk muscle morphology and to postural stability.Studies I and II investigated trunk muscle size, symmetry and function, in dancers with and without LBP, at rest and during simple manoeuvres, with magnetic resonance imaging (MRI). Reduced size of the multifidus muscle was observed in dancers with LBP and dancers with both back and hip/pelvic region pain. This finding is similar to that for nondancers. Study II provided preliminary evidence of a behavioural change in transversus abdominis (the deepest abdominal muscle); expressed as reduced length change of this muscle measured with MRI, in dancers with LBP. Thickness of transversus abdominis, obliquus internus abdominis and multifidus muscles were asymmetrical in dancers but this was not related to LBP. This may be related to repetitive performance of asymmetrical movements. Studies III and IV investigated postural control. In Study III, the trunk was perturbed in order to measure the dynamic properties of stiffness, damping and mass as an indication of control of the trunk. Dancers with LBP had less damping (control of velocity) than dancers without LBP, but this could be changed with motor imagery in the dancers with LBP. Study IV used linear and non-linear measures of centre of pressure trajectories to investigate standing balance in dancers with and without LBP and nondancers. Balance was measured with the feet in parallel and the dance-specific turned out 'first' position; which increases the dependence on trunk motion for balance in the anteroposterior direction. Dancers without LBP used more movement to control balance iii than non-dancers. These findings suggest that "less" movement does not define optimal balance in dancers. Dancers with a history of LBP used strategies that were more s...
