PSA’s and Stuns

Question 1

What is a PSA?

Answer 1

Pressure Sensitive Area.

Question 2

Three key principles when using PSA’s:

Answer 2

1. Verbal direction.
2. Pressure and counter pressure.
3. Apply suddenly, reward compliance.

Question 3

Five major PSA and stuns control principles:

Answer 3

1. Pain compliance.
2. Stunning techniques.
3. Distraction techniques.
4. Balance displacement.
5. Motor dysfunction.

Question 4

Nerve pressure points. Where is the mandibular angle located?

Answer 4

The mandibular angle is located at the base of the ear lobe between the mastoid and the mandible, and the method of application is touch pressure.

Question 5

Nerve pressure points. Where is the Infra-Orbital located?

Answer 5

The infra orbitalin-orbital is located at the base of the nose and the method of application is touch pressure.

Question 6

Nerve pressure points. Where is the hypoglossal located?

Answer 6

The hypoglossal is located approximately one inch forward of the ‘R’ angle of the mandible and one inch under the jaw and the method of application is touch pressure.

Question 7

Nerve pressure points. Where is the Brachial Plexus Tie-In located?

Answer 7

The brachial plexus tie-in is located at the junction of the pectoralis major, the bicep and the deltoid muscles (runs through the shoulder and into the arm). The method of application is striking.

Question 8

Nerve pressure points. Where is the Brachial Plexus Clavicle notch located?

Answer 8

The brachial plexus clavicle notch is located directly behind the clavicle, approximately halfway between the sternum and the shoulder joint. The method of application is touch pressure.

Question 9

Nerve pressure points. Where is the Suprascapular located?

Answer 9

The suprascapular is located at the connection between the trapezius muscle and the side of the neck. The method of application is striking.

Question 10

Nerve motor points. Where is the Radial located?

Answer 10

The radial nerve motor point is one of the nerves that combine to create the brachial plexus. It is located on the top of the forearm, approximately two inches below the elbow joint. The method of application with a radial nerve motor point is a strike.

Question 11

Nerve motor points. Where is the median located?

Answer 11

The median nerve motor point is located on the inside of the forearm (near the base of the wrist); above the heel of the hand. The method of application is striking.

Question 12

Nerve motor points. Where is the Femoral located?

Answer 12

The femoral nerve motor point is located on the inside of the thigh, halfway between the groin and the knee. The femoral never motor point is an alternative target for striking the legs. The method of application is striking.

Question 13

Nerve motor points. Where is the Common Peroneal located?

Answer 13

The common peroneal nerve motor point is located just above the back of the knee where it branches off of the sciatic nerve and travels around the outside of the knee beneath the knee cap (it is located approximately six inches above the knee). The method of application is striking.

Question 14

Nerve motor points. Where is the Tibial located?

Answer 14

The tibial nerve motor point is the lower branch of the sciatic nerve. It starts just above the outside of the thigh and runs down the back of the Leg through the calf muscle (located at the top of the calf muscle, just below the knee joint). The method of application is striking.

Question 15

Shoulder pin theory. What are the two types of neck restraints that cab be used?

Answer 15

1. Vascular neck restraint.
2. Respiratory neck restraint (Lethal - GBH or death).

Question 16

Shoulder pin theory. There are five technical aspects when applying the shoulder pin neck restraint:

Answer 16

• Approach (approach from the 2.5 position).
• Arm placement.
• Grip (Snowball grip).
• Compression (counter pressure).
• Take down procedure.

Question 17

Shoulder pin theory. Three levels of compression:

Answer 17

Level 1.
- Rear neck lock.
- No compression.

Level 2.
- Mechanical compression.
- Conscious compliance.

Level 3.
- Continued compression.
- subject rendered unconscious.

*These levels will vary depending on the subject and the level of resistance. Verbal direction must be used at all times to ensure the subject what you want them to do.
