      <subfield code="a">A methodological study was conducted to provide a multivariate evaluation of the foot/floor interface in constrained standing. Measures of body movement (from force platform and video recording), leg muscle EMGs, reported exertion/discomfort and task performance were taken during a two-hour task. Factor analysis showed four major factors named Body Movement, Muscle Contraction, Perceived Fatigue and Task Errors</subfield>
