Lesson: Fascial Tensioning

Lesson: Fascial Tensioning as a Neurological Signal

What Is Fascial Tensioning?

Fascia is not just passive tissue — it’s filled with mechanoreceptors, especially:

• Ruffini endings (respond to sustained stretch)

• Pacinian corpuscles (detect rapid pressure changes)

• Interstitial receptors (linked to the autonomic nervous system)

When you apply torque, stretch, or compression to fascia, you’re not just changing structure — you’re sending rich proprioceptive input to the brain & spinal cord.

What Happens When You Tension Fascia?

1. Receptors in fascia fire based on angle, direction, and velocity

2. These signals go to the dorsal horn of the spinal cord

3. The CNS interprets this as load, threat, or position change

4. It reacts by:

• Inhibiting certain muscles (to protect joints)

• Activating stabilizers

• Shifting autonomic tone (blood pressure, heart rate, etc.)

This is how a non-painful lock or twist can still cause someone to freeze, fold, or lose control.

Kyusho/Tuite Relevance:

Many pressure point responses are amplified when fascia is under tension:

• A strike to LI10 (forearm) with the arm fully extended torques both the interosseous membrane & surrounding fascia

• This activates more mechanoreceptors than a relaxed strike

• Result: Greater neurological confusion & quicker dysfunction

Bonus: Fascia connects distant areas (e.g., wrist tension affects shoulder positioning), which explains chain reactions in your Tuite.

Application Strategy:

• Apply pre-tension to the joint before striking or locking

• Use angles that spiral fascia, not just bend joints

• Combine with cutaneous or dermatomal stimulation to overload the CNS
