Summary

Classic ballet dance is a demonstration of complex motor skills to be revealed in aesthetic combinations and repetitively, and it demands intensive use of the lower extremities within extreme of range of motion (ROM). Because ballet practice depends on advanced technical skills, it involves intensive physical training and causes an overload on the musculoskeletal system and foot deformities such as pes planus. Plantar venous pump (PVP) is a network of multiple venous vessels located between the muscles of the foot arch. PVP is considered the first step of venous return and discharges into the posterior tibial vein (PTV). PVP is reported to be active during gait while it is inactive in resting position. There are different views on the mechanisms enabling its activation 1-3. The general view is that during the stance phase of the gait, the flattening of the plantar arch with weight transfer causes the veins in this region to narrow and creates a force that pumps the blood up. The aim of this study is the investigation what kind of hemodynamic changes ballet training causes in the lower extremity

Conditions

• Venous Insufficiency
• Foot Drop (Acquired)

Interventions

Type	Name	Description
OTHER	Navicular drop measurement	The difference in navicular height between sitting and standing positions was recorded (mm) as the amount of navicular drop.
OTHER	Measurement of venous return parameters in supine	Venous return parameters of posterior tibial vein was measured when participant applied force equivalent to their own body weight on plantar surface of their right leg in supine position
OTHER	Measurement of venous return parameters in standing	In standing, venous return parameters was measured of posterior tibial vein when participants shift all of their weight to the right leg for 3 second with their leg muscles as relaxed as possible and their knee joint in full extension.
OTHER	measurement of midfoot pressure distrubition	In standing, midfoot pressure distrubution was measured when participants shift all of their weight to the right leg
