Figure 2. Means and standard deviations of posturography variables (i.e. area, mean velocity anterior-posterior, mean velocity mediallateral, mean amplitude anterior-posterior and mean amplitude medial-lateral) for 2 elderly groups with (WC) and without (NC) complaints of imbalance. FSEO: firm surface, eyes open; FSEC, firm surface, eyes closed; CSEO: compliant surface, eyes open; CSEC: compliant surface, eyes closed; Tandem EO: tandem stance, eyes open; Tandem EC: tandem stance, eyes closed; SL R: standing on right foot only; SL L: standing on left foot only. A) FSEO (# p<0.05 vs Tandem EO, Tandem EC, SL R and SL L in groups WC and NC), FSEC (* p<0.05 vs Tandem EO, Tandem EC, SL R, SL L in groups WC and NC), CSEO (& p<0.05 vs Tandem EC, SL R, SL L in groups WC and NC), CSEC ($ p<0.05 vs SL R, SL L in group WC; and Tandem EC, SL R, SL L in group NC).
