Does the Movement Competency Screen Correlate with Deep Abdominals Activation and Hip Strength for Professional and...

Dancers are a unique category of athletes who are frequently injured and experience pain. The primary cause of dance injuries is overuse, which could potentially be prevented. However, literature is scarce regarding validated methods of evaluating the risk of injury in dancers. The Movement Competency Screen (MCS) could potentially fill this gap.

To investigate the validity of the Movement Competency Screen (MCS) for dancers by 1) examining the correlation between scores on this functional test and the activation of deep abdominals and hip strength; 2) investigating the correlation between MCS scores and those of the Functional Movement Screen (FMS™).

Cross-sectional study.

A total of 77 pre-professional and professional dancers from ballet and contemporary backgrounds were evaluated. The activation of deep abdominals was evaluated using ultrasound imaging and the hip strength was evaluated using a handheld dynamometer. The FMS™, another tool evaluating fundamental movement competency, was also administered.

The dancers' MCS score was correlated with the activation of the transversus abdominis (r=0.239, p=0.036) and the strength of hip abductors (r=0.293, p=0.010), adductors (r=0.267, p=0.019) and external rotators (r=0.249, p=0.029). The MCS score was also correlated with the FMS™ score (r=0.489, p<0.001).

This study shows that the MCS score is correlated with deep abdominal activation and hip strength in dancers, as well as with the FMS™ score. These findings provide evidence toward the validation of the MCS in dancers.
