Abstract

A method of electromyographic scanning paravertebral muscles comprising measuring electrical potential across a persons'"'"'s spinous process bilaterally across segments of the spinous process.

Claims

1. A method of electromyographic scanning of paravertabral muscles comprising:

measuring electrical potential with surface electrodes bilaterally across a first segment of a person'"'"'spinous process;

progressing along the spinous process to a second segment of the spinous process; and

measuring electrical potential with surface electrodes bilaterally across the second segment of the spinous process.

2. The method of claim 1 wherein every other spinal segment is measured bilaterally.

3. The method of claim 2 wherein said step of measuring is measured at the limit of a person'"'"'s range of motion.

4. A method of determining paravertabral muscular hyperactivity in a person comprising:

measuring electrical potential with surface electrodes bilaterally across a first segment of a person'"'"'s spinous process to obtain an electrical potential measurement;

progressing along the spinous process to a second segment of the spinous process;

measuring electric potential with surface electrodes bilaterally across the second segment of the spinous process; and

comparing the measurements to a predetermined scale of electrical potential measurements.

5. The method of claim 4 wherein every other spinal segment is measured bilaterally.

6. The method of claim 5 wherein said step of measuring is measured at the limit of a person'"'"'s range of motion.

7. A method of electromyographic scanning of paravertabral muscles of the thoracic and lumbar spine comprising:

measuring electrical potential across a person'"'"'s spinous process bilaterally at a first sacral level, fifth lumbar and every other segment of the spinous progress progressing cephalad and ending at the first thoracic segment.

8. The method of claim 7 wherein said electric potential is measured using surface electrodes.

9. The method of claim 8 wherein said step of measuring is measured at the limit of a person'"'"'s range of motion.

10. A method of electromyographic scanning of paravertabral muscles of the thoracic and lumbar spine of a person comprising:

measuring electrical potential across the person'"'"'s spinous process bilaterally at the first thoracic segment, at the third thoracic segment, and every other segment of the spinous process progressing caudad and ending at the first sacral level.

11. The method of claim 10 wherein said electric potential is measured using surface electrodes.

12. The method of claim 11 wherein said step of measuring is measured at the limit of a person'"'"'s range of motion.

13. A method of determining areas of muscular hyperactivity in a prone person comprising:

electromyographic scanning comprising measuring electric potential with a surface electrode bilaterally across a first segment of a person'"'"'s spinous process;

progressing along the spinous process to a second segment of the spinous process; and

measuring the electric potential with surface electrodes bilaterally across the second segment to obtain electrical potential measurements with;

(a) 0.3-0.5 uv readings indicating that muscles are in a resting state, and not actively contracting;

(b) 0.6-0.7 uv readings indicating that some random firing above which may develop into problem areas;

(c) 0.8-1.1 uv readings indicating problem areas exhibiting palpable spasticity and tenderness; and

(d) 1.2 uv or greater readings indicating problem areas demonstrating pain and marked spasm.

14. The method of claim 13 wherein every other spinal segment is measured bilaterally.

15. The method of claim 14 wherein said step of measuring is measured at the limit of a person'"'"'s range of motion.
