Lower leg and foot contributions to turnout in pre-professional female dancers: A clinical and kinematic analysis
… of joint structure characteristics and ranges of motion at the hip, knee, ankle and foot. The hip joint’s contribution to functional turnout, a dancer’s preferred turnout stance, has received extensive examination, whereas little is known about below-the-hip contributions. Dancers with limited hip …
