A phenomenological model of human posture control is posited. The dynamics are modeled as an elastically pinned polymer under the influence of noise. The model accurately reproduces the two-point correlation function of experimental posture data and makes predictions for the response function of the postural control system. The physiological and clinical significance of the model is discussed.
