Atlas Orthogonal Instrument
Atlas Orthogonal is a low force adjustment (14N) at the top bone of the spine called the 1st cervical (C1) using a percussion wave instrument. Diagnosis of the neck via x-ray analysis and post-graduate education is an additional specialised certification. The adjustment is applied to a specific pre-calculated vector.
Eriksen, et al. (2011) conducted a study of chiropractic upper neck adjustments and its clinical outcomes, patient satisfaction, and symptomatic reactions.
A total of 1090 new patients suffering from upper neck pain were examined by 83 chiropractors in a practice-based research. Results were collected on two occasions separated by two weeks of care.
The measures were:
- Neck pain disability index (100 point scale)
- Oswestry back pain index (100 point scale)
- 11 point numerical rating scale (NRS) for neck, headache, mid-back, and low back pain
- Treatment satisfaction
- Symptomatic reaction (SR)
Chiropractic adjustments of the upper neck over a period of 17 days, demonstrated significant improvement in the neck disability and headache, but also in mid-back and lower back pain and disability. The level of patient satisfaction is high with a rating of 9.1 on the 11-point NRS. These findings require randomised studies for a definitive risk-benefit assessment. However, no study has shown any adverse reaction following adjustment using upper neck techniques.
