Fig.1From: Static and dynamic postural control deficits in aging fragile X mental retardation 1 (FMR1) gene premutation carriersa Center of pressure (COP) standard deviation in the anterior-posterior (AP) and mediolateral (ML) directions. b The α exponent of detrended fluctuation analysis (DFA) of COP time series in both directions are shown as a function of standing condition. FMR1 stands for FMR1 premutation carriers. Between-group differences are marked as * at 0.05 level and ** at 0.01 level. Error bars represent standard errorBack to article page
