According to Murphy, what are the categories of nerve interference?

The categorization of nerve interference into compression, irritation, and reflex alteration is rooted in the understanding of how different types of interferences affect nerve function and communication within the body.

Compression refers to the physical pressure applied on nerves, which can arise from misalignments or dysfunctions in the spine or surrounding structures. This type of interference can lead to decreased nerve function, resulting in symptoms such as pain or limited movement in the affected areas.

Irritation pertains to the chemical or physical stimuli that cause an abnormal response in the nerve. This can happen due to inflammation, toxins, or other factors that disrupt normal nerve signaling. When nerves are irritated, it may lead to increased sensitivity or abnormal sensations.

Reflex alteration encompasses changes in the body's normal reflex actions due to nerve interference. When nerve pathways are disrupted, it can affect the neural circuits that control reflexes, potentially leading to overactive or underactive responses in various bodily systems.

Together, these categories reflect a comprehensive understanding of how various types of interference can disrupt nerve function and, consequently, affect overall health. The detailed classification allows practitioners to better diagnose and treat conditions related to nerve interference in chiropractic care.
