What are trigger points?
Trigger points are essentially knots in muscle that have been there way too long. Trigger points can form through injury, over-use, repetition, postural faults, strenuous exercise/activity and too much inactivity.
Initially, a knot or adhesion will form in the muscle. Everyone has experienced this at sometime and can relate. Over time, these knots lead to a decreased blood flow in that specific area. We need that blood in order to bring the muscles oxygen. Less blood flow will equal less oxygen.
Our muscles still want to produce energy/movement for us, but it becomes difficult to do so in this oxygen deprived environment. The body will begin to produce energy anaerobically (without oxygen).
The end result of this biochemical reaction is lactic acid. Pockets of lactic acid form what is known as trigger points. Trigger points are sore to the touch, cause general pain and tend to follow specific patterns. Long distance runners will experience oxygen deficient muscles in what has become known as the "runner's burn."
Nimmo/Pressure points: Also called the Nimmo
Receptor-Tonus Method, this technique is now taught in most
chiropractic colleges. A normal muscle has
normal tonus (muscle
tone). Accident, insult, and injury may cause pain, muscle knots and muscle spasm.
If this situation exists for a sufficient time, it can change the
position of bones, producing subluxations (misalignments), body distortions, low hips,
etc. Later a trigger point may form in the muscle which sends a barrage
of painful impulses into an area producing constriction of the blood
vessels with consequent damage to surrounding tissues.
However, it was
discovered that pressure applied in proper degree, at proper intervals,
will release both trigger points and muscle spasm. The doctor will
either use their hands, or at times use a Wooden "T-Bar" with a rubber
tip, to apply a steady pressure to a specific area. This method is
often used in conjunction with chiropractic adjustments and other
modalities. Many conditions that are encountered in general
chiropractic practice can be successfully treated using the Nimmo
Many times I use other techniques to break up adhesions/trigger points. I often will use nimmo in conjunction with additional therapies.
