Effect of different gait conditions on cognitive performance and cortical activity in healthy older adults

The randomized, controlled intervention study has a total duration of 16 weeks and includes five measurement appointments, each at four-week intervals - initial examination, t

Inclusion criteria
Inclusion criteria: • Age and Status: 60 + years and pension • if secondary and/ or voluntary employment, in total less than or 5 hours per week • Ability to walk and no walking aids • no to little experience in walking barefoot; walking on socks is also included, as very similar movement patterns between walking barefoot and walking on socks • already moving as much/stand as much on your feet as the minimum wearing time in week 12 (5 hours per day on 4 days per week) dictates; also moving as much in the apartment on cold day (assuming allocation 'barefoot‘) —> respondent should not move extra, but should interact in the existing daily routine to avoid effects by increasing activity levels • Shoe size less than or equal to 47 and greater than or equal to 36 or trying on shoes before issuing the documents to be filled out, as only shoe sizes 36 to 47 can be served by the manufacturer • Signal variance less than 7.5 % (NIRx Medical Technologies, 2017)
Exclusion criteria
Exclusion criteria: • untreated hearing loss (if hearing aid, one that can register all sounds) • cognitive impairment due to acute or long-term medical condition • relevant neurological diseases; "relevant" means that neither the measurements (e.g., unrestricted operation of all keys and pedals of the VTS) nor the intervention (e.g., wearing times) can be affected • relevant psychiatric diseases • (serious) relevant orthopedic diseases or corrections in the lower extremities and trunk, especially no artificial joints, prostheses (except dentures or mamma prostheses) and orthoses • relevant vestibular diseases (balance) • relevant shoe inserts or elevations • relevant support stockings • relevant compression stockings • relevant acute or not yet fully healed injury (e.g. inflamed ankle joint) • untreated arterial hypertension at rest (from a blood pressure of 140/100 mmHg)
