CLA EMG intruments are computerized surface electrode paraspinal electromyographs manufactured by the Chiropractic Leadership Alliance. The instrument measures the electric potentials produced by muscles surrounding the spine, innervated by the nearby spinal nerves.

The special value of this technique is that it provides objective evidence of nerve compression  in place of the subjective signs afforded by the other methods of observation. The information provided by this test is valuable for diagnosis, prognosis, and patient monitoring.

This technique is completely non-invasive. Electrodes are placed on the skin overlying the spine at 15 or 25 specific sites. The EMG signals of the patient being examined are compared to

a normative database. The doctor is then able to determine the location and extent of abnormal paraspinal muscle and nerve function.

Surface electrode paraspinal electromyography is well supported in medical, chiropractic, and scientific literature. The technique is taught and researched under the aegis of several accredited chiropractic colleges. No needles are employed. Because the technique is non-invasive, it is within the scope of chiropractic.

The initial NERVE study helps provide diagnostic information and aids in the design of appropriate treatment procedures. Re-evaluations monitor patient response to care, dictate changes in care or frequency of scheduling, and helps determine when the patient has reached 'maximal improvement.' It enables the clinician to provide objective 'hard copy' documentation of soft tissue injury.

Scans, taken in concert with other examination findings, may be helpful in diagnosing the following:

1. Sciatica (pain and numbness in legs and feet)
2. Cervical Radiculitis (Pain and numbness in arms and hands)
3. Intercostal Neuritis
4. Herniated or Degenerative Discs
5. Nerve impingements caused by motor vehicle accidents or other trauma
6. Asymmetrical contraction
7. Aberrant recruitment pattern
8. Severity of the condition
9. Responses to chiropractic adjustment
