Description

Pain relief is a major goal of physiotherapy for patients with acute or persistent pain conditions. The purpose of this study is to explain a mechanism-based approach to pain management with physiotherapy. There is evidence that patients need to be evaluated for changes in peripheral tissues and nociceptors, signs and symptoms of neuropathic pain, decreased central depression and increased central excitability, psychosocial factors, and motor system changes. This perspective defines five categories of pain mechanisms (nociception, central nervous system, neuropathy, psychosocial, and motor system) and provides principles for assessing the signs and symptoms of each mechanism. It also describes the underlying mechanisms covered by common physiotherapy treatments and how they affect each of the five categories. Several different mechanisms can contribute to the patient's pain at the same time. Alternatively, one or two major mechanisms can cause pain in the patient. In addition, there can be many possible subgroups within a single pain mechanism. For example, a decrease in central depression does not necessarily correlate with an increase in central excitability. To personalize care, common physiotherapist interventions such as training, exercise, manual therapy, and transcutaneous electrical nerve stimulation can be used to target specific pain mechanisms. Evidence for elucidating these pain mechanisms continues to evolve, but the approach outlined here provides a conceptual framework for applying new knowledge as progresses.

Our ability to translate pain complaints and sensory findings into specific pathophysiological mechanisms that affect treatment is still in its infancy. Clinical studies of pain mechanisms are labor-intensive and require specialized equipment. Therefore, they are not yet practical for routine clinical use. Even professional pain studies are difficult to identify the mechanism of specific neuropathic pain. Simple localized peripheral nerve injury unleashes many processes in the peripheral and central nervous system, all of which can contribute to persistent pain and abnormal sensations. Nervous tissue repair mechanisms that respond to inflammation, injury, and adjacent tissue responses to injury result in a hyper excited state of primary afferent nociceptors, a phenomenon called peripheral sensitization. Central neurons innervated by such nociceptors then undergo dramatic functional changes, including a hyper excitatory state called central sensitization. Normally, these sensitizations disappear spontaneously as the tissue heals and the inflammation subsides. However, if primary afferent function is significantly altered by nervous system damage or illness, these processes are persistent and highly resistant to treatment.

The evidence supporting the use of certain physical agents in the treatment of chronic pain conditions is not conclusive. It is largely incomplete and sometimes inconsistent. However, drug use in chronic pain management programs is common. Of the widespread use of physical means, they are rarely the only method of treatment. The 1995 American Physical Therapy Association's view states: Unless there is a document justifying the need for exclusive use of physical means/modality, the use of physical means/modality should be tolerated unless there are other qualified therapeutic or educational interventions. Physical therapy may serve as a useful auxiliary modality to relieve pain or to increase the effectiveness of other elements in treatment aimed at resolving movement disorders and restoring physical function. Given that it is unlikely that there will be a definitive summary of the results of all sequences of a patient's condition in combination with interacting therapies, an evidence-based approach to pain management is always possible or beneficial to the patient. It is not always the case. In the face of conclusive evidence, a theory-based approach determines whether the therapeutic effect of a particular physical agent represents a useful clinical tool in the context of treating the mechanism of pain development in a particular patient. Careful monitoring of an individual patient's response to the wise theoretical use of additional physical agents can be a wise approach to the management of chronic pain until the outcome of controlled efficacy is final.
