Characterizing music and dance relationships on Rhythmic Movement Sequence performance in healthy adults and those with MCI: A Pilot Study of Rhythmic Movement Sequences Público

Abstract

Importance: Rhythmic movement sequences (RMS) are modified gait movements set to various rhythms to create movement-rhythmic patterns of varying and increasing complexity that investigate participants’ relationship with learning spatial (movement shape) and temporal (rhythm) variables during trials.

Objective: To determine group differences in RMS performance and characterizing music and dance relationships that are translated into performance on RMS trials.

Design/Setting: Cross-sectional pilot study.

Participants: 8 healthy young adults (HYA; age = 24 ± 4.8 yrs; 6Female (F)), 7 healthy old adults (HOA; age = 70 ± 11.5 yrs; 4F), and 8 adults with MCI (MCI; age = 71 ± 6.4 yrs; 5F).

Main Outcome and Measure: RMS trial performance, Music Relationship Questionnaire, Dance Relationship Questionnaire, Rhythm Assessment

Results: When comparing RMS performance between groups, HYA performance on spatial RMS trials was significantly better than MCI (5.71% difference; p = 0.005). When comparing group performance on spatiotemporal trials, HYA performance on spatiotemporal trials was significantly better than MCI (3.42% difference; p = 0.008). When regressing music relationships and temporal trial performance, there was no significant correlation between music relationship and performance on temporal trials between all groups. When regressing dance relationships and spatial trial performance, there was no significant relationship or trend identified between dance relationship and spatial performance between all groups. When regressing dance relationships and temporal trial performance, there was a significant correlation between dance relationship and performance on temporal trials amongst HYA (R²= 0.74; y = -2.97x; p = 0.008). There was a statistically significant relationship identified for HYA between rhythm assessment score and performance on temporal trials (R² = 0.75; y = -2.41x; p = 0.006).

Conclusion and Relevance: To our knowledge, this is the first study that investigates music and dance spatial and temporal components using RMS on HYA, HOA, and MCI. Furthermore, it is not necessarily known what mechanisms differ between these groups and drive differences in performance on spatial, temporal, and spatiotemporal RMS. This thesis investigated how relationships to music and dance and proficiency in rhythm impact the ability to perform spatial and temporal modifications to gait and how that changed in individuals with different physical and cognitive abilities.
