ABSTRACT
Despite Ankle Injuries being one of the most common injuries inflicted on dancers, the relationship between ankle strength, flexibility, and balance still remains a lack of definition.This research study aims to determine how these factors interact with each other and whether a specific combination of strength and flexibility can predict better balance and therefore lower ankle injury risk in dancers. To investigate these questions, the study will assess dancers using goniometric measurements of ankle range of motion (dorsiflexion, plantar flexion, inversion, and eversion), handheld dynamometry for ankle strength, and a standardized balance assessment known as the Star Excursion Balance Test. Participants will also complete a pre screening survey, along with a demographic and injury‑history survey to identify if the participant is eligible and if any patterns can be found between past injuries and current physical measures. Data will be analyzed using a multiple regression to determine whether ankle strength and flexibility are predictors of balance performance and whether these variables differ between dancers with and without prior ankle injuries.
The research was inspired by the high prevalence of ankle sprains in dance populations and the lack of consensus on whether increased flexibility enhances performance or increases vulnerability to injury. Understanding how these components interact can have a positive effect on injury prevention, dance training, and rehabilitation. By identifying the most effective combination of strength and flexibility for optimal balance, this research may guide evidence‑based conditioning programs that reduce injury risk and support long‑term dancer health and performance.
