Clinical Trial
e-Ouch: usability testing of an electronic chronic pain diary for adolescents with arthritis.
The aim of this study was to evaluate the usability of the e-Ouch electronic chronic pain diary in adolescents with juvenile idiopathic arthritis. ⋯ A multifaceted usability approach provided important insight regarding the use of technology by adolescents with arthritis and, more specifically, for understanding how adolescents can more effectively use an electronic chronic pain diary.

Controlled Clinical Trial
The level of small nerve fiber dysfunction does not predict pain in diabetic Neuropathy: a study using quantitative sensory testing.
To determine whether small nerve fiber dysfunction predicts pain in diabetic neuropathy using quantitative sensory testing of thermal thresholds. ⋯ Quantitative sensory testing of small nerve fiber function is a useful test to detect the presence of neuropathy, and overall diabetic patients with neuropathic pain have more sensory loss. However, small nerve fiber abnormalities detected by quantitative sensory testing do not predict the presence of pain in diabetic neuropathy.

Review Meta Analysis
Are manual therapies effective in reducing pain from tension-type headache?: a systematic review.
A systematic review was performed to establish whether manual therapies have specific efficacy in reducing pain from tension-type headache (TTH). ⋯ The authors found no rigorous evidence that manual therapies have a positive effect in the evolution of TTH. The most urgent need for further research is to establish the efficacy beyond placebo of the different manual therapies currently applied in patients with TTH.

Clinical Trial
Complex regional pain syndromes: the influence of cutaneous and deep somatic sympathetic innervation on pain.
Complex regional pain syndromes (CRPS) can be relieved by sympathetic blockade. Different sympathetic efferent output channels innervate distinct effector organs (ie, cutaneous vasoconstrictor, muscle vasoconstrictor. and sudomotor neurons, as well as neurons innervating deep somatic tissues like bone, joints, and tendons). The aim of the present study was to elucidate in CRPS patients the sympathetically maintained pain (SMP) component that exclusively depends on cutaneous sympathetic activity compared with the SMP depending on the sympathetic innervation of deep somatic tissues. ⋯ Sympathetic afferent coupling takes place in the skin and in the deep somatic tissues, but especially in the acute stages of CRPS, the pain component that is influenced by the sympathetic innervation of deep somatic structures is more important than the cutaneous activation. The entire sympathetic maintained pain component is not constant in the course of the disease but decreases over time.

In low back pain, clinical studies suggest that kinesiophobia (fear of movement/(re)injury) is important in the etiology of chronic symptoms. In this prospective cohort study, the predictive role of kinesiophobia in the development of late whiplash syndrome was examined. ⋯ Although a higher score on the TSK-DV was found to be associated with a longer duration of neck symptoms, information on early kinesiophobia was not found to improve the ability to predict the duration of neck symptoms after motor vehicle collisions.
