Abasia (from Greek: a-, without and basis, step) is the inability to walk due to impaired muscle coordination. The American Heritage Medical Dictionary defines abasia as "Inability to walk due to impaired muscular coordination.a" [1]

The term covers a spectrum of medical disorders such as:

  • choreic abasia: caused by chorea of the legs
  • paralytic abasia: caused by paralysis of the leg muscles
  • spastic abasia: caused by spastic stiffening of the leg muscles
  • trembling abasia: caused by trembling of the legs

Abasia is frequently accompanied by astasis, an inability to stand.

An associated term is dysbasia, a partial abasia
