Dance Intervention to Improve Executive Function and Physical Performance in Older Adults With Cognitive Impairment

Mild Cognitive Impairment (MCI) is an age-related condition that affects memory, judgment, and motor performance, often leading to reduced independence and quality of life. Recent studies have emphasized the interrelationship between cognitive and motor functions, particularly in individuals with neurodegenerative conditions. Interventions that incorporate dual-task training, such as dance, have shown promise in enhancing both domains by combining rhythmic movement, memory recall, physical coordination, and social interaction.

Dance-based interventions, especially those integrating music, external cues, and partner interaction, engage multiple brain regions including the frontal cortex, cerebellum, and hippocampus. These programs stimulate sensory-motor integration and executive control, potentially improving attention, gait, balance, and cognitive flexibility. Existing evidence supports that rhythm- and music-based movement, when combined with cognitive tasks, can enhance brain function, promote emotional regulation, and improve daily functioning in cognitively impaired populations.

This study aims to examine the effects of a structured, music-based dance intervention on executive function and physical performance in middle-aged and older adults with cognitive impairment. The program integrates fixed dance routines with perceptual-motor training and social interaction.

A total of 50 middle-aged and older adults receiving outpatient rehabilitation at a medical center in northern Taiwan were recruited and randomly assigned to either the music-based dance intervention group (n = 25) or the control group (n = 25). The intervention group participated in a nine-week group-based program involving rhythmic movement, mutual physical guidance, and social interaction. The control group completed a nine-week lower limb intermittent exercise program guided by non-musical instructional videos.

Assessments were conducted at three time points: pre-intervention, mid-intervention, and post-intervention. Evaluation tools included:Four-Square Step Test (FSST), Functional Reach Test (FRT), Timed Up and Go - Cognitive (TUG-Cognitive), Montreal Cognitive Assessment (MoCA), Stroop Color and Word Test (SCWT), Modified Borg Rating of Perceived Exertion (RPE), Course feedback questionnaire. Descriptive statistics were used to summarize participant demographics. Repeated measures analysis of variance (ANOVA) was used to examine within-group and between-group differences over time. Statistical analyses were performed using SPSS Statistics 26.0, with the significance level set at α < 0.05.
