Abstract
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.3Steadiness 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 All of these components of balance (steadiness, symmetry, and dynamic stability) have been found to be disturbed following stroke.2,4,5
