Upon testing passive range of motion at varying speed,the physical therapist observes a catch and resistance through less than half of the available range when moving the limb at faster speeds.What type of tone is this and what grade would it receive on the Modified Ashworth Scale?

The description matches spasticity, which is characterized by a velocity-dependent increase in tonic stretch reflexes with exaggerated tendon jerks. The Modified Ashworth Scale grades spasticity, and a catch and release or minimal resistance through less than half the range of motion (especially at faster speeds) is graded as 1+.
