Imagine a garden hose as a nerve and the water flowing through the hose as nerve impulses. When the hose is lying straight without any kinks, water flows through it freely. if the hose gets compressed or kinked, water flow is reduced or even stopped. If the compression or kinking isn’t fixed, the hose can eventually be damaged.
Like removing the kink from the hose, a spinal adjustment can ease pressure on a nerve, allowing nerve impulses to flow and protect the nerve from further damage.
A pop or click sound it often heard during an adjustment. Doctors call this cavitation. Much like opening a can of carbonated soda, the sound is caused by a rapid change in pressure acting on the fluids within the joint. Cavitation often occurs during an adjustment, but it does not have to occur for the adjustment to be effective.
