Chapter 3: General Neuropathodynamics

This is a Chapter 3 summary of “Clinical Neurodynamics” by Michael Shacklock. What it is General neuropathodynamics are abnormalities consistent throughout the nervous system, with specific referring to local abnormalities. These changes may lead to a neurogenic pain experience, in which pain is initiated by a primary lesion, dysfunction, or transitory perturbation in the nervous system. This definition means that dysfunction in the nervous system, it’s surrounding tissues, and innervated tissues can all be related to neurogenic pain. Definitions of Clinical Problems When discussing dysfunction, there are several descriptors: 1)      Optimal/desirable: When the neuromusculoskeletal system behaves well and does not create symptoms in situations of high stress. 2)      Suboptimal: Imperfect neuromusculoskeletal behavior which results in potential symptom increasing if an adequate trigger occurs. 3)      Normal: Function of neuromusculoskeletal system is within normal values. 4)      Abnormal: Neuromusculoskeletal system is outside of the normal range. 5)      Relevant: When pathodynamics are linked to the clinical problem. 6)      Irrelevant: When pathodynamics are not linked to the clinical problem. You will oftentimes have multiple of these components in a clinical situation. Mechanical Interface Dysfunction These dysfunctions deal with abnormal or undesirable forces on the nervous system. There are two main categories with their own subcategories. 1)      Closing dysfunctions – Altered closing mechanisms of the movement complex. Can be reduced (protective response) or excessive (hypermobility/instability). 2)      Opening dysfunctions – Altered opening mechanisms of the movement complex. Can be reduced which creates impaired pressure reduction, or excessive leading to tissue traction. Pathoanatomical Dysfunction This type of dysfunction is
