Kikkert LHJC, et al. – Objectives of this study were to quantify gait outcomes based on dynamical systems theory and to determine their discriminative power in 3 groups: healthy old adults, geriatric patients with– and geriatric patients without cognitive impairment. The authors found no differences in gait between geriatric patients with and without cognitive impairment while geriatric patients vs. healthy old adults walked slower, and less regular, predictable, and stable. The effects of multiple comorbidities on geriatric patients’ gait possibly caused a ‘floor–effect’, with no room for further deterioration when patients develop cognitive impairment. Thus, an accurate identification of cognitive status required a multifactorial approach.
