Effect of Classic Ballet Practice on School Children's Postural Balance

Effect of Classic Ballet Practice on School Children's Postural Balance: Randomized Clinical Trial

Is a parallel longitudinal protocol where half patients receive a experimental protocol and the other half receive orientation to maintain your daily live routine as usually. The experimental protocol include Ballet sessions. The hypothesis is interventional group will improve the balance control more than control group.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Ballet; Subjects who will receive the experimental protocol.	Other: Ballet; The classic ballet classes will respect biological limits of children. The sessions will be 75 minutes long, twice a week during 8 weeks. The class sequence will be: warm-up, follow by exercises about upper and lower limbs ballet positions and sequences of ballet jumps, and at the end a cool-down.
No Intervention: Control; Subjects who will not receive the experimental protocol, only will be on a wait list.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in total score of Star Excursion Balance Test at 8 weeks.	Changing between the beginning and end of intervention. This measure is shown in cm.	Before, immediate after intervention protocol
Change from baseline in anteriorposterior and mediolateral displacements of Pressure Center at 8 weeks.	Changing between the beginning and end of intervention of anteroposterior and mediolateral displacements of pressure center in cm.	Before, immediate after intervention protocol
Change from baseline in average speed of Pressure Center at 8 weeks.	Changing between the beginning and end of average speed of pressure center in cm/s.	Before, immediate after intervention protocol
Change from baseline in 95% ellipse area of Pressure Center at 8 weeks.	Changing between the beginning and end of 95% ellipse area of pressure center in cm².	Before, immediate after intervention protocol
Maintenance at 30 and 60 days from baseline in total score of Star Excursion Balance Test.	Changing between the end and 30 and 60 days after intervention. This measure is shown in cm.	Immediate after, 30 and 60 days after intervention protocol.
Maintenance at 30 and 60 days from baseline in anteroposterior and mediolateral displacements of pressure center	Changing between the end and 30 and 60 days after intervention of anteroposterior and mediolateral displacements of pressure center in cm.	Immediate after, 30 and 60 days after intervention protocol.
Maintenance at 30 and 60 days from baseline in average speed of pressure center	Changing between the end and 30 and 60 days after intervention of average speed of pressure center in cm/s.	Immediate after, 30 and 60 days after intervention protocol.
Maintenance at 30 and 60 days from baseline in 95% ellipse area of pressure center	Changing between the end and 30 and 60 days after intervention of 95% ellipse area of pressure center in cm².	Immediate after, 30 and 60 days after intervention protocol.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Vertical stiffness	Stiffness estimate by force plate data and displament of center of mass	Before, immediate after, 30 and 60 days after intervention protocol
Peak and absortion rate of ground reaction force	Greatest value and absortion rate (between inicial contat and peak) of ground reaction force	Before, immediate after, 30 and 60 days after intervention protocol

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity level	Assessed by final score of Physical Activity Questionnaire for Children. The score questions are about daily physical activity of children. Final score is a mean calculate by 9 items/questions with range 1 to 5. A final score of 1 (minimum) indicates low physical activity, whereas a score of 5 (maximum) indicates high physical activity.
