Can short, frequent tango sessions sharpen walking and thinking in older adults?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Aged 55 to 60 years at the time of enrollment. Able to stand and walk independently without physical assistance from another person. Able to understand the study procedures and complete the walking, balance, physical function, and cognitive assessments. No regular dance training during the previous 6 months. Willing to maintain usual daily activities and avoid beginning another structured dance or balance-training program during the study. Cleared for moderate-intensity exercise based on the Physical Activity Readiness Questionnaire for Everyone (PAR-Q+) or an equivalent exercise safety screening. Medical clearance will be required when indicated. Willing and able to attend the assigned intervention sessions and complete the scheduled assessments. Able to provide written informed consent. Exclusion Criteria: Uncontrolled hypertension, unstable angina, recent myocardial infarction or stroke, severe cardiac arrhythmia, or another cardiovascular condition that makes moderate-intensity exercise unsafe. A neurological disorder that substantially affects gait, balance, cognition, or the ability to complete the study procedures. Severe cognitive impairment, psychiatric illness, or communication difficulty that prevents understanding of the study or valid completion of the assessments. A recent fracture, severe musculoskeletal disorder, acute joint injury, severe dizziness, or another condition associated with an unacceptably high risk of falling or exercise-related injury. Current participation in another structured dance, balance, cognitive-motor, or exercise intervention study that may affect the study outcomes. Any other medical or functional condition that, in the judgment of the study investigator or qualified safety assessor, makes participation unsafe or may interfere with completion of the study.
