The Connection Between Better Lung Function and Spinal Nerves
The spine is an amazing feature of human anatomy; the vertebrae protect your spinal cord, spinal nerves emerge through a hole called the foramina in the vertebrae, and these nerves then innervate different parts of the body. The philosophy of chiropractic medicine is based on the theory that nerves may be compressed and it affects areas of the body that the nerves normally serve. Once the nerve compression is alleviated, nerves can heal and do what they are supposed to do, no matter what part of the body the nerves are affecting.
In a study, 87 Swedish chiropractors were surveyed on what types of symptoms were improved with their patients. Of the patients that received benefits, 26 percent reported that it was easier to breathe. The more areas of the spine that were treated, the more health improvements were reported (such as improved digestion, vision and circulation).
That’s good news — but it gets better.
In an Australian study of 15 patients with chronic obstructive pulmonary disease (COPD) of moderate severity, five received soft tissue therapy, five received soft tissue plus spinal manipulation, and the remaining five received soft tissue therapy, manipulation and exercise. Lung function was measured before and at the end of four weeks. Those in the group that received all three treatments had better lung capacity and walked longer distances. Those who received manipulations had less gasping for breath and no one in the study experienced any negative side effects.
Why It Works
What is it about chiropractic manipulation that improves symptoms of COPD? If the chest wall can’t move well, COPD will progress. Reducing this impairment improves the overall prognosis. Manipulation of the spine (and soft tissue therapy) increases the range of motion in the joints and decreases muscle spasticity. The end result is easier breathing and less work for the respiratory muscles to do in breathing. Overall there is less shortness of breath.
Chiropractic treatment more often than not involves spinal manipulation. Depending on the chiropractor, it may also include nutritional advice and/or therapeutic exercise.
Breathing is controlled by a breathing center in the brain stem. The nerve cells, called neurons, in the brain stem send signals to the diaphragm and muscles in between the ribs. Did you know the cervical nerve roots are also involved? The cervical nerve roots are the nerves that emanate from the spine, enter the foramen (or hole) in the spinal vertebrae and travel to the corresponding body parts.
What Parts of the Body Are Innervated by Spinal Nerves?
Here is a run down of what spinal nerves control what parts of the body:
- C1 and C2 cervical spinal nerves control the head.
- C3 and C4 control the diaphragm, the major muscle involved in breathing. This muscle allows your chest cavity to expand so you can take more air into your lungs. It works 24/7 whether you are awake or sleeping. Any injuries to the phrenic nerve can occur during surgery involving the neck or the chest but can also occur during epidural injections, as well as injuries during a fall, car accident, or work injury.
- C5 cervical spinal nerves control the deltoid muscles and the biceps muscles.
- C6 controls the muscles that extend the wrist and the biceps.
- C7 controls the triceps muscles.
- C8 spinal nerve roots control the hands.
