Jump sign is the involuntary flinch or pull-away when a 📝tender point is pressed.
The person startles, grimaces, or moves the limb before they have decided to. In 📝Trigger Point Therapy that response is information: the spot is live, and the dose may already be too high. It is not a diagnosis, not a test of toughness, and not a cue to press through. The useful next step is less pressure, more time, and a breath.
Clients often apologize for jumping. The practitioner treats it as data, not as a failure of stillness. Repeated jump signs on the same pass mean the hold is above tolerance.
