Repetitive painful laser stimuli lead to physiological laser-evoked potential (LEP) habituation, measurable by a decrement of the N2/P2 amplitude. The time course of LEP-habituation is reduced in the capsaicin model for peripheral and central sensitization and in patients with migraine and fibromyalgia. In the present investigation, we aimed to assess the time course of LEP-habituation in a neuropathic pain syndrome, i.e. painful radiculopathy. ⋯ Abnormal central pain processing in neuropathic pain conditions may be revealed with the laser-evoked potential habituation paradigm. In painful radiculopathy patients, LEP-habituation is reduced compared to healthy controls.

Osteoporotic vertebral fractures (OVF) can lead to late collapse which often causes kyphotic spinal deformity, persistent back pain, decreased lung capacity, increased fracture risk and increased mortality. The purpose of our study is to compare the efficacy and safety of vertebroplasty against conservative management of osteoporotic vertebral fractures without neurologic symptoms. ⋯ In our study on OVF, vertebroplasty delivered superior clinical and radiological outcomes over the first year from intervention when compared to conservative treatment of patients with osteoporotic compression fractures without neurological deficit. We believe that the possibility of evolution towards progressive kyphosis is sufficient to justify prophylactic and therapeutic intervention such as vertebroplasty, a minor gesture compared with extensive correction surgery and stabilization.

Muscle pain may reorganize trunk muscle activity but interactions with exercise-related muscle fatigue and delayed onset muscle soreness (DOMS) is to be clarified. ⋯ Back muscle activity decreased during unilateral and increased during bilateral pain after unpredictable surface perturbations during muscle fatigue and DOMS. Accumulation effects of DOMS on pain intensity and spreading and trunk muscle activity after pain-induction.

The objective of this review was to evaluate the efficacy of pulsed radiofrequency (PRF) treatment of pain associated with different spinal conditions. The mechanisms of action and biological effects are shortly discussed to provide the scientific basis for this radiofrequency modality. ⋯ From the available evidence, the use of PRF to the dorsal root ganglion in cervical radicular pain is compelling. With regard to its lumbosacral counterpart, the use of PRF cannot be similarly advocated in view of the absence of standardization of PRF parameters, enrolment criteria and different methods in reporting results; but, the evidence is interesting. The use of PRF in lumbar facet pain was found to be less effective than conventional RF techniques. For the other different spinal conditions, we need further studies to assess the effectiveness of PRF. Advances in knowledge: The use of PRF in lumbar facet pain was found to be less effective than conventional RF techniques. For the other different spinal conditions, we need further studies to assess the effectiveness of PRF.

Case ReportsAn Unusual Cause of Back Pain in a 10-Year-Old Girl.
A 10-year-old girl with a 2-week history of atraumatic back pain presented to the emergency department with difficulty ambulating and a history of 2 episodes of urinary incontinence in the past week. Her examination was significant for pain with movement, tenderness to palpation in the lower thoracic spine, and no neurological deficits. In this case, the child was found to have a Schmorl node at T8 in the superior aspect of the vertebral body. ⋯ The diagnosis was made by magnetic resonance imaging. The child's symptoms significantly resolved with ibuprofen anti-inflammatory therapy. In children with atraumatic back pain lasting greater than 2 weeks with a sudden increase in severity and associated with a neurological deficit, advanced imaging is strongly recommended.
