Which Tx Inhibition Technique uses the dissociation of the upper and lower trunk with trunk rotation and pelvic positioning to lengthen a shortened muscle?

• A. Joint Approximations
• B. Trunk Rotation and Pelvic Positioning
• C. NMES
• D. Massage and Myofascial Release

Answer: (B)

The idea behind this technique is to lengthen a shortened muscle by placing it in a longer resting length through strategic body positioning. By dissociating the upper from the lower trunk and adding trunk rotation with specific pelvic positioning, the muscle must span a greater distance. This changes the muscle’s length-tension relationship and reduces reflexive tone, promoting gradual elongation and easier stretch over time. It targets the neuromuscular system through position and rotation rather than forcing a contraction or compressing joints. Joint approximations mainly increase joint compression and stability, not lengthening. Electrical stimulation (NMES) aims to elicit contractions rather than sustained passive lengthening. Massage and myofascial release focus on fascia and soft tissue mobility without the segmental trunk dissociation and rotation used here.
