Clinical Trial Summary

Dance is a performing art form consisting of sports and art intertwined and complex dynamic choreographic figures were handled aesthetically and physically of narrative. Scientific studies are insufficient on dance and health and performance of dancers in the literature although dance is the most used type of art and sport in all societies and for all age groups. It is seen that the core stabilization (central forces) of the dancers is insufficient when the current studies were examined, this insufficient stabilization causes biomechanical changes in the trunk, and indirectly affects the lower extremities. Consequently, insufficient stabilization was shown to be caused impairment of force generation and injuries. In addition, lack of core stabilization of dancers may cause impairment in balance and postural control. Therefore, dancers need a good postural control with provided by an effective core stabilization training in order to exhibit a successful and healthy performance. It is shown that inspiratory muscle training (IMT) improves diaphragm strength and diaphragm thickness. Considering the relation between diaphragm muscle forming the upper (ceiling) part of the core area, and balance, IMT may also have an impact on postural control and balance alongside the standard clinical parameters such as respiratory muscle strength and diaphragm thickness in dancers. Thus, the aim of this study was to investigate the effects of inspiratory muscle training on diaphragm thickness, postural stability, balance, respiratory muscle strength in dancers.

Related Conditions & MeSH terms

• Athletic Injuries
• Respiratory Aspiration

Intervention

Other:
• Inspiratory muscle training(high-IMT group)
A mechanical pressure threshold loading device (POWERbreathe, POWERbreathe International Ltd, UK) will be used for the training. Training intensity will set at 60% of the maximum inspiratory pressure.
• Inspiratory muscle training(low-IMT group)
Dancers will be perform at a load setting of level 1 (corresponding to ~10% baseline MIP), using the same device as the training group.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of baseline postural stability test score in Biodex Balance System after 8 weeks	The Postural Stability Test evaluates static balance of participants. Postural Stability Test emphasizes a patient's ability to maintain center of balance. The patient's score on this test assesses deviations from center, thus a lower score is more desirable than a higher score.	Eight weeks
Primary	Change of baseline athlete single leg stability score in Biodex Balance System after 8 weeks	The test protocol for the Athlete Single Leg Stability Testing allows clinicians to test athletes against data derived from studies using the Biodex Balance System. The stability level will challenge athletes and provide the data necessary to assess the athlete's single leg postural stability.	Eight weeks
Primary	Change of baseline limits of stability test score in Biodex Balance System after 8 weeks	Limits of stability test evaluates dynamic balance of participants. Biodex balance system measures limits of stability for forward, backward, right and left side movements. It will calculate the maximum distance a person can lean without losing balance.	Eight weeks
Primary	Change of baseline diaphragm thickness after 8 weeks	Two-dimensional B-mode ultrasound will be measure diaphragm thickness at the zone of apposition during inspiration or expiration using the intercostal approach. Diaphragm thickness will be measure as the vertical distance between the pleural and peritoneal layer at both Total Lung Capacity [TLC] and Functional Residual Capacity [FRC]. Measurements will be perform on the right hemidiaphragm with the volunteer in the supine position. All measurements will be perform 3 times and the average value for each calculate.	Eight weeks
Primary	Change of baseline maximum inspiratory pressure after 8 weeks	Maximum inspiratory pressure (MIP) will be measure using a hand-held mouth pressure device. Three maximal manoeuvres will perform and the highest value record. Indirect measure of respiratory (inspiratory) muscle strength, expressed in cmH20.	Eight weeks
Primary	Change of baseline maximum expiratory pressure after 8 weeks	Maximum expiratory pressure (MEP) will be measure using a hand-held mouth pressure device. Three maximal manoeuvres will perform and the highest value record. Indirect measure of respiratory (expiratory) muscle strength, expressed in cmH20.	Eight weeks
Secondary	Change of baseline biering-sorenson test score after 8 weeks		Eight weeks
Secondary	Change of baseline oswestry disability index after 8 weeks		Eight weeks
