Muscle tone is a NEUROLOGIC phenomenon.
It depends on the nervous system working without interference.
The basic unit of neurological function is the neurological impulse which leads to axonal depolarisation. It mostly originates in the muscle spindle cells and periodontal ligaments, tissues which, uniquely, spontaneously generate afferent input.
At least 90% of our muscular activity is actually quite unconscious and is mostly controlled by reflexes.
Muscle spindle afferents are the primary source of the myotatic reflex and it is the input from these afferents that ascend to the brain as well as moderate and mediate motor neuron output via the propriospinal tracts. Thus, muscle spindle afferents are the primary source of body position sense and are an integral part of control and regulation of muscle tone, as well as central nervous system function.
If you want to change muscle tone quickly, the most effective way is to change afferent input. In this case, changing input via the periodontal ligaments strengthened this patient’s lumbar extensors, allowing him to bend and stand up again with little to no pain. Removing the offending crown allowed for full recovery.

Afferent Input is the common denominator of all therapies. It explains why they work when they do and the hidden reasons why they don’t work when they should. With Afferent Input in your practice, your goal to make your patients better faster and easier becomes a reality.
To get you started our Foundations of Afferent Input course is FREE. It only takes 20 – 30 minutes and it covers and revises the basic anatomy and physiology you need to know to understand Afferent Input. The Afferent Input Solution is where we show you the power of understanding Afferent Input.
