Introduction[edit | edit source]

Definition[edit | edit source]

Rigidity is a hypertonic state characterized by constant resistance throughout range of motion that is independent of the velocity of movement. It is the result of excessive supraspinal drive (upper motor neuron facilitation) acting on alpha motor neurons; spinal reflex mechanisms are typically normal.[1]
