Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Patients will be included in the present study when they are (a) 65 years or older; (b) visit the Department of Medical Psychology of the Slotervaart Hospital for a neuropsychological examination; and (c) able to walk at least 160 meter without using any assistive device.

Exclusion criteria

Exclusion criteria: Patients will be excluded for the present study when they (a) have any mobility problems due to (lateral) neurological or orthopedic disorders with function limitations of one or both legs; (b) are unable to understand and follow simple verbal instructions; or (c) have severe visual impairments.

Design outcomes

Primary

Measure	Time frame
The outcome variables of the 160-meter walking test whit accelerometry. Walking speed is recorded, and foot contact moments are derived from anterior-posterior (AP) accelerations, whereof mean and coefficient of variation (CV) of stride times, stride frequency, consistency of timing, and long term correlations are calculated. From AP and medio-lateral (ML) trunk acceleration patterns, variability, regularity, long range correlations, and local stability are calculated. All variables quantify another aspect of gait variability and stability. The outcome parameters of the neuropsychological tests include scores on tests for the following cognitive domains: (a) memory: word list learning, memorizing stories and paired learning; (b) executive function: verbal fluency, divided attention, selective attention and problem solving; (c) language: confrontation naming; (d) visuo-spatial function: copying pictures; and (e) attention: digit span and mental speed.	—
