This technique involves moving the affected joint diagonally through multiple planes just to the point of a spastic response, which is when the muscle spindle organs in the muscle group, being stretched, begin to trigger the hyperactive reflex that causes spasticity in that muscle group. The muscle group is then contracted at 50% to 100% intensity for 6 to 8 seconds,
which inhibits the reflex and allows the joint to be moved beyond this point [78]. With time, substantial gains in ROM can be achieved.
