Once thus precisely matched to the average patient of a large group study, risk reduction is calculated by multiplying the measured similarity of the clinical patient to the risk of the average trial patient.
Center of pressure (COP) displacements are commonly used to evaluate balance performance in the elderly, 20 and COP path length was validated as a performance outcome measure in a large group study.
