👉 Orthostichies, also known as orthotaxis, are a type of movement disorder that involves the loss of the ability to maintain balance and coordination. This condition is characterized by involuntary movements that can be difficult or impossible to control, such as slouching, hunching over, or crossing one's legs. It often affects both sides of the body, including both arms and legs. Orthostichies are often associated with neurological conditions or injuries that affect the central nervous system.
