Clinical Assessment of Chronic Musculoskeletal Pain-A Framework Proposal Based on a Narrative Review of the Literature

The assessment of chronic musculoskeletal pain (CMP) is a challenge shared by several health professionals. Fragmented or incomplete assessment can cause deleterious consequences for the patient's function. The objective of this paper was to propose a framework for clinical assessment of CMP based on the current literature and following the conceptual model of the International Classification of Functioning and Health (ICF). We propose that the ICF rationale may help to guide the processes, acting as a moderator of the clinical assessment, since it changes the perspective used to obtain and interpret findings during anamnesis and physical examination. Additionally, updated specific knowledge about pain, including that of pain domains and mechanisms, along with effective patient-clinician communication may act as a mediator of CMP assessment. We conduct the readers through the steps of the clinical assessment of CMP using both the proposed moderator and mediators and present a clinical example of application. We suggest that the proposed framework may help clinicians to implement a CMP assessment based on the biopsychosocial model using a critical and updated rationale, potentially improving assessment outcomes, i.e., clinical diagnosis.

[Lower back pain in the primary care setting - Non-specific and specific pain]

A systematic survey of the symptoms of back pain in terms of triggering event and onset, nature and the extent of influenceability of the pain (lying or standing, under stress, nocturnal pain, localized percussion tenderness, B- symptoms, etc.), as well as structured clinical examination (segment height, radiance, projection, reflex status, sensitivity and motor function) allows an initial and therefore orienting classification of back pain as non-specific or specific. In the primary care setting many patients can be treated extremely effectively and economically from a cost perspective. In addition to the fastest possible pain relief, it is important to prevent the disease becoming chronic. A wide range of pharmacological treatment can be combined with non-pharmacological measures, such as early on exercises, promoting every day mobility, physiotherapy, manual therapy etc.. 20 % of patients with lower back pain have a determinable cause that needs to be rapidly identified. In addition to laboratory diagnostics, structured morphological imaging is necessary. Causes of specific back pain include: fractures, infections, radiculopathy, tumors, axial spondylarthritis as well as extravertebral causes. In the further cause of treatment, it may be necessary to consult medical specialists in the fields of radiology, orthopedics, neurology, neurosurgery, rheumatology, psychotherapy, psychiatry, among others. Treatment is managed by the primary care provider, who should also receive and re-evaluate all findings during the course of the disease.

[Back pain in the primary care setting : Specific back pain]

Back pain is a common reason for consulting a general practitioner. For 80% of patients, the back pain is nonspecific. Specific back pain has a determinable cause that needs to be rapidly identified. The diagnostic work-up to clarify spinal pain involves a detailed patient history taking into account the "red flags", a clinical examination and further stepwise diagnostics. In addition to laboratory diagnostics, structured morphological imaging is necessary. Causes of specific back pain include: fractures, infections, radiculopathy, tumors, axial spondylarthritis, as well as extravertebral causes. The diagnosis, treatment and continuous follow-up of the patient with specific back pain is interdisciplinary and requires close communication with the relevant specialists.
