In contrast to practice alone (no BF, gray bars), practicing with BF (black bars) does not improve postural stability during tandem gait immediately afterwards (short term retention). Group mean percent change before (average of trials 1–3) and after (trials 28–30) practice with or without biofeedback. A significant retention of postural stability was seen in step frequency error after practice either with or without BF but Trunk Tilt SD and ML Step Variability showed retention only after practice without BF (near zero average % change post-pre practice trials with BF).
