Chiropractic is an impulse delivered through contact with another person, causing a sensory stimulus with an intent to produce a co-ordinated or strength response and functional restoration / preservation.
In Physics an impulse is considered to be force over time. ‘Force’ can be broken down into magnitude, direction and point of contact. The time element of an impulse can be applied through acceleration (slow to quick).
Therefore an Impulse is a targeted sensory input (affecting proprioception, vestibular, and/or tactile senses) that modulate motor output (muscle strength and joint alignment).
Chiropractic is like tuning the piano. Exercise is playing the music and the music is your genetic profile…
If the piano keys are stuck or out of tune, you can’t play well — no matter how much you practise or how good the music is.
There’s no accumulated benefit to practising on an out of tune piano.
