Atlas Orthogonal Technique

Atlas Chiropractic or the Atlas Orthogonal (AO) technique is a safe and pain-free technique that we offer at Performance Chiropractic. It uses percussive sound waves to restore the natural balance of the spine. It’s the ideal solution for anyone suffering from neck pain, migraines, headaches, MS, post-concussion syndrome, fibromyalgia, anxiety, brain fog, and more. It is gentle, accurate, and effective. We do not do any twisting, cracking, or popping of the spine here. We focus on aligning your spine from the top and keeping it in alignment so that you don't have to continue seeing us forever!

What is Chiropractic Care?

Chiropractic care is a traditional, scientific, complementary, and alternative healthcare discipline that concerns itself with the diagnosis and healing of mechanical impairments of the spine. Doctors of Chiropractic are trained professionals who have obtained formal chiropractic education and training to diagnose and treat patients suffering from neuro-musculo-skeletal dysfunctions, such as muscular or skeletal pains, joint and bone ailments, and neurological disorders affecting other organs and functions of the body. Despite popular belief, chiropractors can help a lot more than neck pain and back pain. Since the spine is what protects the nervous system, and the nervous system controls everything in the body, chiropractic care can help people heal from all sorts of aches and pains, including neurological issues like migraines, headaches, trigeminal neuralgia, occipital neuralgia, TMJ or jaw pain, earaches, vertigo or dizziness, fibromyalgia, chronic pain syndrome, insomnia, post-concussion syndrome, and more.

Symptoms a Chiropractor Can Help With

Many people who are suffering from back pain, joint pain, or any other aches and pains in their body turn to chiropractic care as a way to get some relief. There is no question that chiropractic care is valuable in the proper instances - when a person is having an acute injury or suffering from a pre-existing condition that is causing severe pain.

Some common symptoms:

Many people choose to receive chiropractic care to relieve pain, improve range of motion, and prevent future injury. Benefits of seeing a chiropractor are worth the time and effort as they will improve your overall health and well-being.
