How cognitive loads modulate the postural control of older women with low back pain?

Abstract Background The capacity of postural control is a key factor related to falling in older people, particularly women with low back pain (LBP). Cognitive involvement increases age. However, most scholars have not considered different difficulty levels cognitive loads when exploring the effects cognition on patients LBP. present study investigate how modulate Methods This was cross-sectional study. Twenty LBP were recruited into group, and 20 healthy without history group. Balance parameters computed quantify control. All participants underwent balance test, which required participant maintain stability during standing force platform or concurrent task. test included three difficulties posture tasks (eyes-open vs. eyes-closed one-leg stance) (without task auditory arithmetic serial-7 s task). Results A repeated-measure analysis variance (3 × 3 congnitive tasks× 2 groups) testing performance conditions. Older had worse (as reflected by larger center pressure (COP) parameters) than group regardless difficulties. Compared single task, COP dual tasks, even though level low. Larger shown only if high Correlations between sway area/sway length number falls significant tasks. Conclusion Our findings shed light for showed more disturbing LBP, associated falling.
