The Cainzian Factor
I Postulate that the major reason for muscle spasm along the distribution of the sciatic nerve, the brachial plexus, and along the para spinal musculature is caused by a compromise in the distribution of nerve fluid.
This lack of nerve fluid to the muscle results in an irritation and subsequent spasm of the muscle. When the nerve fluid has been compromised, it sets off an alarm that something has “gone wrong”. The body wants to lock down the area being effected by the decrease in nerve fluid to protect itself from further injury.
The major reason for the decrease in nerve fluid is pressure on the nerve. There are many possible causes. Most involve the disc to some extent. The most common and fixable cause is subluxation. The vertebra being slightly out of alignment causes pressure to be exerted on the spinal cord or the nerve roots. These structures that cause this compromise, are:
The disc and the edema of the joint that ensues after the misalignment.
The vertebra itself. As the vertebra misaligns, it becomes closer to the spinal cord and nerve roots.
Once a muscle is in spasm due to the Cainzian factor it can be a trigger point. Trigger points can be said to be either active or latent.
- Active trigger points are painful and are painful with or without being touched.
- Latent trigger points are painful to the touch but not actively painful, to the patient, if not touched.
The Cainzian factor points out that these trigger points might have been caused by a direct cause. A direct cause of these trigger points would be injury due to over stressing the muscle with exercise, work or an accident. Of course this happens. But muscle actually heals fairly quickly, usually in about 72 hours. After 72 hours an injury to the muscle would be well on its way to being healed. But the reality is that this trigger point, if it does not go away or becomes worse as time goes on, is most likely due to a compromise in the nerve fluids that innervate that muscle which is manifesting the trigger point.
What about the latent trigger point? Why is it latent or not active? According to the Canzian factor, this “latent” trigger point will usually be further away from the source of distribution; The source being the spine and nerve roots. Due to its distal muscle position, the latent trigger point is not as sensitive to a lack of nerve fluid compared with the muscle that manifests the active trigger point, for two reasons:
1. It is either further down the line of nerve innervation and is used to not having as much nerve “fluid” as the muscle which is manifesting the active trigger point.
2. It has another source of nerve innervation from another nerve root. This other source from a branch of another nerve root gives this muscle enough fluid to keep it under the threshold of active spasm.
The Cainzian factor says that muscle spasm will be found in a “line”, if you will, along the distribution of a nerve root. For example: If the C5/C6 nerve root is being compromised by disc degeneration, you may find muscle spasm in the anterior deltoid muscle and the biceps. If you “search” for muscle spasm or “trigger points”, you will find that these muscle spasms have a common source, a compromised nerve root that is responsible for these muscle spasms. You may find that the anterior deltoid is an “active” trigger point, while the biceps is a “latent” trigger point. You may find that the anterior deltoid is an “active” trigger point; Because, due to it’s original muscle spasm, it was further injured by “over use”, (also it is more proximal compared with the biceps). Once a muscle spasm has manifested due to a compromise of nerve fluid, it can become easily injured by seemingly normal activities. The reason for this injury was due to the fact that an underlying muscle spasm was present, while the patient made the move, (reaching into the back seat). The muscle was already in spasm (cainzian factor) and once in spasm was not “elastic”, not being “elastic” the reaching over exerted the muscle, causing a “tear” to ensue. I believe that this scenario is the major cause of most shoulder injuries.
As you can see, instead of exercising the injured muscle, you must increase nerve innervation and get to the “root” of the problem.
