Multicenter Study Clinical TrialThe European multicenter trial on the safety and efficacy of guided oblique lumbar interbody fusion (GO-LIF).
Because of the implant-related problems with pedicle screw-based spinal instrumentations, other types of fixation have been tried in spinal arthrodesis. One such technique is the direct trans-pedicular, trans-discal screw fixation, pioneered by Grob for spondylolisthesis. The newly developed GO-LIF procedure expands the scope of the Grob technique in several important ways and adds security by means of robotic-assisted navigation. This is the first clinical trial on the GO-LIF procedure and it will assess safety and efficacy. ⋯ This trial will for the first time assess the safety and efficacy of guided oblique lumbar interbody fusion. There is no control group, but the results, the outcome and the rate of any complications will be analyzed on the background of the literature on instrumented spinal fusion. Despite its limitations, we expect that this study will serve as the key step in deciding whether a direct comparative trial with another fusion technique is warranted.

Multicenter StudyStages of chronicity in fibromyalgia and pain catastrophising: a cross-sectional study.
Fibromyalgia (FM) is a prevalent and disabling disorder characterised by widespread pain and other symptoms such as insomnia, fatigue and depression. Catastrophisation is considered to be a key clinical symptom in FM; however, few studies have investigated how contextual factors, such as catastrophisation, might contribute to the duration of the pain. The present research examined the relationship among pain, catastrophic thinking and FM impact, as a function of stage of chronicity. ⋯ These findings provide preliminary evidence that stage of chronicity is an important moderator of psychological vulnerability for FM impact and should be taken into account by tailoring psychological interventions.

Comparative StudyLow back pain: what determines functional outcome at six months? An observational study.
The rise in disability due to back pain has been exponential with escalating medical and societal costs. The relative contribution of individual prognostic indicators to the pattern of recovery remains unclear. The objective of this study was to determine the prognostic value of demographic, psychosocial, employment and clinical factors on outcome in patients with low back pain ⋯ Analysis controlling for confounding variables, demonstrated that participants showed greater improvement if their episodes of pain during the previous year were short-lived while those with Middle Eastern, North African and Chinese ethnicity demonstrated minimal improvement. The study did not support previous findings that a wide range of factors could predict outcome.

Kinematics of fast cervical rotations in persons with chronic neck pain: a cross-sectional and reliability study.
Assessment of sensorimotor function is useful for classification and treatment evaluation of neck pain disorders. Several studies have investigated various aspects of cervical motor functions. Most of these have involved slow or self-paced movements, while few have investigated fast cervical movements. Moreover, the reliability of assessment of fast cervical axial rotation has, to our knowledge, not been evaluated before. ⋯ Peak speed of fast cervical axial rotations is reduced in people with chronic neck pain, and even further reduced in subjects with concomitant low back pain. Fast cervical rotation test seems to be a reliable and valid tool for assessment of neck pain disorders on group level, while a rather large between subject variation and overlap between groups calls for caution in the interpretation of individual assessments.

Comparative StudyPressure pain sensitivity maps of the neck-shoulder and the low back regions in men and women.
Musculoskeletal pain in the low back and neck-shoulder regions is a major problem among the working population all over the world. The prevalence of musculoskeletal pain is found to be higher among women. Women also have lower pressure pain thresholds (PPTs) than men. Pressure pain topography aims at mapping the spatial distribution of PPT within a muscle in an attempt to track changes in mechanical sensitivity. In order to assess gender differences in the pain topography, it is necessary to map the distribution in both healthy men and women. The aim of this study was to assess PPT maps from the cervico-thoracic and lumbar regions in men and women. ⋯ The pain topography was not found to be different between genders in the cervico-thoracic and lumbar regions. This study can be used as basis for further clinical studies on musculoskeletal disorders.
