Which PNF technique is NOT a strengthening technique?

• A. Slow-reversal-hold-relax
• B. Rhythmic stabilization
• C. Hold-relax
• D. Combination of isotonic

Answer: (A)

In PNF, some techniques are aimed at increasing muscle strength through dynamic resistance and controlled contractions, while others focus on improving range of motion and lengthening muscles through inhibition and stretch. Rhythmic stabilization builds strength by challenging the joint with co-contraction around it, helping to improve stability and force production. Hold-relax is used mainly to increase range: an isometric contraction of the target muscle is held, then the muscle relaxes and the limb is moved into a new, greater range. Combination of isotonic directly involves resisted concentric and eccentric contractions to strengthen. Slow-reversal-hold-relax combines a slow reversal (dynamic movement) with a hold-relax segment; the hold-relax portion is a stretch-based technique designed to increase range, not to maximize muscle strength, so this one is not a strengthening technique.
