Which of the following activities best describes proprioceptive neuromuscular facilitation?
a.
the stretch involves using an external object to increase muscle strength.
b.
the stretch involves using a partner to apply force against your contraction.
c.
the stretch involves bouncing to extend beyond the normal range of motion.
d.
the stretch involves performing slow, deliberate motions to reduce muscle tightness.

B.The stretch involves using a partner to apply force against your contraction.

Explanation:

The proprioceptive neuromuscular facilitation is a method used in muscular rehabilitation, it involves a partner helping you applying forca agains your muscular contaction in order to extend more the muscle and with this gradual movement taht estimulates the nerves and neuromuscular receptors in an attempt to make a more effective movement.
