Proprioceptive Neuromuscular Facilitation stretching involves which features?

• A. A stretching technique that involves combinations of alternating contractions and stretches such as slow-reversal-hold-relax, contract-relax, and hold-relax
• B. Static holds for 60 seconds
• C. Ballistic bouncing
• D. Passive stretching only

Answer: (A)

PNF stretching relies on combining muscle contractions with stretching to unlock greater joint range. During these protocols, you actively contract the target muscle (often against resistance) and then relax, allowing a deeper passive stretch to follow. Patterns like slow-reversal-hold-relax, contract-relax, and hold-relax implement this back-and-forth sequence, using neural mechanisms such as autogenic and reciprocal inhibition to facilitate a longer, more flexible length. This approach typically requires a partner or clinician to guide the contractions and apply the proper resistance so the stretch progresses safely and effectively.

Static holds, ballistic bouncing, or stretches performed passively without any purposeful contraction don’t utilize these contraction–stretch sequences and are not characteristic of PNF.
