Pain and Split-belt Motor Learning in Older Adults

Recruiting now · Not applicable

Conditions studied: Aging, Older Adults, Pain, Motor Learning

In brief

The purpose of this research is to investigate the impact of acute pain, induced using an experimental pain paradigm of capsaicin paired with heat, on implicit locomotor learning and its retention in older adults.
