Balance retraining after stroke using force platform biofeedback

Balance is a somewhat ambiguous term used to describe the ability to maintain or move within a weight-bearing posture without falling.(1,2) Balance can further be broken down into three aspects: steadiness, symmetry, and dynamic stability.(3) Steadiness refers to the ability to maintain a given posture with minimal extraneous movement (sway). The term symmetry is used to describe equal weight distribution between the weight-bearing components (eg, the feet in a standing position, the buttocks in a sitting position), and dynamic stability is the ability to move within a given posture without loss of balance.(3)
