Asymmetric bondage
From wipipedia.org
Asymmetric bondage is a type of sexual bondage in which the bound person is tied in asymmetric positions. This has a disorienting effect, confusing the body's self-image and sense of balance, and hence increasing the psychological impact of the bondage. Asymmetric bondage is a common technique in Japanese bondage.
A common technique is to make the person stand on one foot and bind the other leg, for example with an ankle to thigh bind.
