Evaluation of the Correlation Between Flamenco Dance and Ankle and Foot Posture.

Background: The practice of flamenco dance involves great biomechanical demands, comparable with a high-performance sport. The technical movements of the footwork tap, the jumps, and the turns increase the prevalence of injuries and pathologic disorders of the foot and lower limb. Limited research has examined adaptation of the foot posture and dorsiflexion of the ankle in flamenco dancing. Therefore, the aim of this study was to evaluate whether the practice of flamenco dancing produces modifications in the ankle's dorsiflexion range of motion, Foot Posture Index, or pronation.

Methods: A cross-sectional observational study with intentional sampling was performed with 26 individuals (52 feet) in two groups: professional female flamenco dancers (n = 13) and nondancers (n = 13). The participants were assessed in a single session for ankle dorsiflexion, foot pronation (navicular drop test), and foot posture (Foot Posture Index).

Results: Significant differences were found between the two groups for left foot Foot Posture Index (P = .007) and right foot navicular drop test (P = .006).

Conclusions: The results of this study indicate that flamenco dancing can produce modifications in the Foot Posture Index and foot pronation versus nondancers. Further research is required.
