Note: for a backbone in functional state, the typical norm or compensated state is:

• the amplitude of blue measurements (A1) in the diagram is 3-5% higher than the one of red measurements (A2);
• the 'Group norm corridor' is the value of the red and blue diagrams' averaged amplitudes within the range 40-60%.
  

Amplitudes analysis for the blue and red diagrams:

• The 'individual norm corridor' is the corridor (two dashed lines) in the range of +/- 7% of the diagram's averaged amplitude.
• Amplitudes within the ranges of the 'individual norm corridor' is the NORM or COMPENSATED PROCESS.
• Amplitudes closer to the diagram's centre relative to the 'individual norm corridor' are an ACUTE or SUBACUTE PROCESS.
• Amplitudes closer to the diagram's edge relative to the 'individual norm corridor' are a CHRONIC PROCESS.
  

Examples of vertebrograms analysis

4. Hypermobility (instability) - the amplitude for both red and blue is markedly directed to the diagram's edge in comparison with the other vertebrae (equally strong towards the edge - to Yin А1 = А2) (usually after fixation).

Hypermobility at vertebrae level C3 and C6
Muscular block at vertebra level Th1

5. Area of hypermobility - amplitudes of 3 and more vetebrae for both red and blue are markedly directed to the diagram's edge in comparison with the other vertebrae (3 and more vertebrae equally strong towards the edge - to Yin А1 = А2)
Area of hypermobility at cervical vertebrae level C3 - C6
Muscular block at Th1

6. Ligaments block - the amplitude for red and blue diagrams is directed towards the centre in comparison with other vertebrae. The amplitude of the opposite diagram is at the norm level (А1 - markedly to the centre, to Yang, А2 is within the norm, but not too distinct, or vice versa).

Ligament block at Th4 - Th5 level

7. Subluxation - the amplitudes of the higher vertebra are markedly directed towards the centre - to Yang, and the amplitudes of the lower one - to the edge - to Yin).
Subluxation at vertebrae level Th3 - Th4

8. Total osteochondrosis
The amplitude for red and blue diagrams is as close as possible to the edge along the whole diagram.

9. Osteoporosis
For patients over 50, measured by projection zones above the spinal processes.

For patients measured in the Su Jok microsystem, this reading most often indicates a stress state, rather than osteoporosis.

The amplitudes for red and blue diagrams are as close as possible to the centre.
