Clinical Disorders and the Sensory System
We would all like to thank Dr. Richard C. Schafer, DC, PhD, FICC for his lifetime commitment to the profession. In the future we will continue to add materials from RC’s copyrighted books for your use.
This is Chapter 4 from RC’s best-selling book:
“Basic Principles of Chiropractic Neuroscience”

Chapter 8: Clinical Disorders and the Sensory SystemThis chapter describes those sensory mechanisms, joint signals, and abnormal sensations (eg, pain, thermal abnormalities) that have particular significance within clinical diagnosis. The basis and differentiation of pain are described, as are the related subjects of trigger points and paresthesia. The chapter concludes with a description of the neurologic basis for the evaluation of the sensory system and the sensory fibers of the cranial nerves.
THE ANALYSIS OF PAIN
IN THE CLINICAL SETTING
Although all pain does not have organic causes, there is no such thing as “imagined” pain. Pain that can be purely isolated as a structural, functional, or an emotional effect is rare. More likely, all three are superimposed upon and interlaced with each other in various degrees of status. This is also true for neural, vascular, lymphatic, and hormonal mechanisms.
Common Causes of Pain and Paresthesia
The common causes of pain and paresthesia are:
(1) obvious direct trauma or injury;
(2) reflex origins in musculoskeletal lesions, which deep pressure often exaggerates, such as trigger areas;
(3) peripheral nerve injury (eg, causalgia), which results in an intense burning superficial pain;
(4) the presence of nerve inflammations and degeneration of the peripheral or CNS, which frequently cause other changes indicative of such lesions; (more…)
