Kinematic Analysis of Dance-Based Exergaming: A Cross-Sectional Study

Area of Science:

• Biomechanics
• Rehabilitation Technology
• Geriatric Medicine

Background:

• Dance-based exergaming (DBExG) improves postural stability and mobility in older adults and stroke survivors.
• Age-related deficits and stroke-induced cortical pathology may alter movement adaptations during DBExG.

Purpose of the Study:

• To examine movement kinematics (postural stability, mobility) across different dance paces in healthy young adults, healthy older adults, and older adults with chronic stroke.
• To compare movement adaptation patterns during DBExG between these groups.

Main Methods:

• 33 participants (11 per group: young adults, healthy older adults, older adults with stroke) performed DBExG.
• Participants engaged with slow, medium, and fast-paced songs, involving anteroposterior (AP) and mediolateral (ML) movements.
• Key metrics included center of mass (CoM) sway area and excursion, and joint excursions (hip, knee, ankle).

Main Results:

• Young adults showed greater CoM sway area and excursion than older adults with stroke during slow-paced dance.
• Young adults had more AP CoM peaks than both older adult groups during fast-paced dance.
• Young adults and healthy older adults exhibited greater joint excursions than older adults with stroke across all paces.

Conclusions:

• Quantitative analysis of movement patterns provides a basis for assessing therapeutic DBExG protocols.
• Findings highlight distinct kinematic differences that can guide personalized rehabilitation strategies for different populations.
• This research supports the development of tailored DBExG interventions for aging populations and stroke survivors.
