PTA Physical Therapy Assistant

Answer: C - According to the Maitland graded oscillation techniques, Grade II is large-amplitude, rhythmic oscillations that are performed within the range, not reaching the limit.
Maitland oscillation Grades I and II are used to reduce pain. Grades III and IV are used to stretch the joint capsule and passive tissues to increase the range of motion.
In Grade III, large-amplitude, rhythmic oscillations are performed up to the limit of the available range of motion and are stressed into the tissue resistance.

In Grade IV, small-amplitude, rhythmic oscillations are performed up to the limit of the available range of motion and are stressed into the tissue resistance.

In Grade I, small-amplitude, rhythmic oscillations are performed at the beginning of the range of motion.
