Currently, physicians examine patients clinically by evoking pain symptoms through palpation, range of motion, strength testing, and sensory stimulation. The patient describes the severity of the evoked discomfort by gradations [e.g., mild, moderate, severe, excruciating]. The physician then interprets the patient’s verbal response and other physical responses in an effort to empirically assess the cause and gravity of the problem. This venerable technique holds multiple ambiguities. The patient’s description is the sum total of physical tenderness, emotional responses, and social context. The physician judgments are strongly influenced by training, personal experience, and attitudes. The resulting imprecision can create incorrect medical conclusions leading to over or under-treatment with high cost or ineffective therapies. There is also the problem of factitious behavior and malingering. The etiology of a patient’s pain symptoms is critical to planning appropriate care. It is illogical to treat a subject with primary depression, anxiety or social problems with protracted physical modalities, increasing narcotics, anesthetic blocks or surgery; it will not work. On the other hand, inaccurately blaming a complaint on depression, anxiety, the wrong medical process, or malingering causes treatment failure that could otherwise be corrected. If a given individual has a chronic pain complaint that can be evoked by a bedside clinical examination, then NPP can reproduce similar test conditions to accurately and unequivocally assess the parameters underlying a patient’s claim of pain. It will do so in a manner that is patient specific, stimulus specific, and tissue-selective.
When the nervous system is subjected to sufficient stress, it must respond for ubiquitous reasons of protection and survival. This response phenomenon is found in all animals including humans. Pain threshold “OIT” is, by definition, a sufficient stimulus to create stress.
The data from each pair of Control/Test sites is analyzed graphically and statistically from a variety of clinically relevant perspectives. OIT levels are compared to assess the claim of physical tenderness [odynia]. The PRC tracings are graphically analyzed to evaluate physical, psychobiological, and socio-dynamic characteristics. Parametric statistics are done on intra-site perturbations to evaluate whether the graphic interpretation is valid. Parametric statistics are done between Control and Test Sites to evaluate whether the graphic interpretation is valid.
