What is the tardieu scale? The tardieu scale is also used to assess spasticity.  It uses three different velocities of movement as well as two different points in time.  R1 is the point in motion where spasticity is first felt and R2 is the full range of motion.  It can be further reviewed at the

What do muscle spindles, golgi tendon organ, and renshaw cells have to do with spasticity?   In brief, muscle spindles record the change in length and trigger the stretch reflex.  Golgi tendon organs regulate muscle contraction to cause equal tension throughout the movement.  Renshaw cells control the stretch reflex by preventing overactivity of the stretch
