Which option names the Post Isometric Relaxation (PIR) Muscle Energy Technique (MET)?

• A. Contract relax procedure
• B. Post isometric relaxation (PIR) muscle energy technique (MET)
• C. PNF hold relax stretching technique
• D. Reciprocal inhibition stretch

Answer: (B)

This item tests the exact naming of the technique known as Post Isometric Relaxation Muscle Energy Technique. PIR MET is a muscle energy technique where the patient performs a brief isometric contraction at a comfortable length against a stable counterforce, usually held about 5–10 seconds. After the contraction, the patient relaxes and the clinician lengthens the muscle further, taking advantage of the post‑isometric relaxation that follows, which helps reduce muscle tone and increase range of motion. The term PIR MET itself identifies this specific method.

The other descriptions refer to different techniques. Contract–relax is another MET variant that uses a voluntary contraction followed by relaxation but is not the PIR naming. PNF hold–relax is a stretching approach within proprioceptive neuromuscular facilitation, not specifically PIR MET. Reciprocal inhibition stretch relies on reciprocal inhibition to stretch but is not named PIR MET.
