Ning Qu, Rene Lindstrøm, Rogerio Pessoto Hirata, Thomas Graven-Nielsen
BACKGROUND: Patients with neck pain normally showed alterations in cervical motion and pressure pain sensitivity. Cervical joints show scattered motions opposite to (anti-directional) the primary motion direction (pro-directional) during dynamic cervical flexion and extension. This study aimed to assess dynamic cervical joint motion and pressure pain sensitivity when pain originated from different cervical muscles which may have clinical relevance in diagnosis of impairments related with neck pain...

A rat model of neuropathic pain at 6 weeks after spinal nerve ligation (SNL6w) exhibits both mechanical hypersensitivity and impaired noxious stimuli-induced analgesia (NSIA). Repeated treatment with antidepressants can produce anti-hypersensitivity and restore NSIA. To examine the involvement of a brain-derived neurotrophic factor-mediated mechanism, a tropomyosin receptor kinase B (TrkB) agonist, 7,8-dihydroxyflavone (DHF), was administered to SNL6w rats (5 mg• kg-1 • day-1 , 5 days). Mechanical hypersensitivity was evaluated using the von Frey filament test and paw pressure test...

Intramuscular injection of nerve growth factor (NGF) causes muscle hyperalgesia without immediate pain. This double-blinded, randomized study assessed pain and muscle hypersensitivity after a single-site bolus NGF injection (5µg) compared with five spatially distributed, low-dose NGF injections (1µg, 4cm distance) into the tibialis anterior (TA) muscles in 20 healthy subjects. Injection-pain was rated on a visual analogue scale (VAS). Reports of muscle pain with functional tasks (Likert scale score) and presence of spontaneous pain were collected daily using a diary...

Background: The fibromyalgia (FM) physiopathology involves an intracortical excitability/inhibition imbalance as measured by transcranial magnetic stimulation measures (TMS). TMS measures provide an index that can help to understand how the basal neuronal plasticity state (i.e., levels of the serum neurotrophins brain-derived neurotrophic factor (BDNF) and S100-B protein) could predict the effect of therapeutic approaches on the cortical circuitries. We used an experimental paradigm to evaluate if pregabalin could be more effective than a placebo, to improve the disinhibition in the cortical circuitries in FM patients, than in healthy subjects (HS)...

Roller massage (RM) can be painful and induce muscle activity during application. Acute increases in pain pressure threshold (PPT) and range of motion (ROM) have been previously reported following RM. It is unclear whether the RM-induced increases in PPT and ROM can be attributed to changes in neural or muscle responses. To help determine if neural pain pathways are affected by roller massage, transcutaneous electrical nerve stimulation (TENS) was utilized as a form of electroanalgesia during RM with PPT and ROM tested on the affected and contralateral quadriceps...
