Tightness of the iliopsoas results in a dancer having difficulty lifting their leg into high positions.

The most obvious signs of lumbar hyperlordosis are lower ...

Other signs from the Thomas test: opposite/ contralateral hip flexes without knee extension- tight iliopsoas; hip abducts during the test- tight tensor fasciae latae; knee extension occurs- tight rectus femoris; Lateral rotation of tibia- tight biceps femoris
