During routine clinical evaluation, it can be challenging to differentiate between lumbar radiculopathy (RAD) and lower back pain with non-radicular somatic referred pain (SRP) or even axial non-radiating low back pain (LBP). The aim of this study was to characterize patients with RAD, axial LBP (aLBP), and SRP on the basis of somatosensory profiles. ⋯ Patients with RAD demonstrated more somatosensory abnormalities than did patients with aLBP and SRP, including increased mechanical hyperalgesia and a loss of mechanical detection. The combination of pressure pain threshold, mechanical detection threshold, numbness, and prickling in the area of LBP can be a time-efficient tool to identify patients with RAD.

Exercise is the most recommended treatment for chronic low back pain (CLBP) and is effective in reducing pain, but the mechanisms underlying its effects remain poorly understood. Exercise-induced hypoalgesia (EIH) may play a role and is thought to be driven by central pain modulation mechanisms. However, EIH appears to be disrupted in many chronic pain conditions and its presence in people with CLBP remains unclear. As people suffering from chronic pain often exhibit psychological factors and central sensitization symptoms influencing pain perception, EIH might be associated with these factors. ⋯ The lower EIH following wrist exercises may represent an alteration in pain modulation control in CLBP. However, psychological factors and central sensitization symptoms may not explain the differences observed.

Lumbar spine intervertebral disc desiccation is associated with medical comorbidities linked to systemic inflammation.
Symptomatic disc degeneration is a common cause of low back pain. Recently, the prevalence of low back pain has swiftly risen leading to increased patient disability and loss of work. The increase in back pain also coincides with a rapid rise in patient medical comorbidities. However, a comprehensive study evaluating a link between patient's medical comorbidities and their influence on lumbar intervertebral disc morphology is lacking in the literature. ⋯ III (retrospective cohort).

This study aimed to carry out a cross-cultural adaptation of the Core Outcome Measures Index (COMI) for use in Traditional Chinese-speaking patients with low back pain (LBP) and to investigate its psychometric properties. ⋯ The Traditional Chinese COMI represents a practical and reliable tool for the assessment of Traditional Chinese-speaking patients with back problems.
