Background. Neck and shoulder pain is one of the most common problems of the musculoskeletal system (De Meulemeester et al., 2017). Work-related neck and shoulder pain is one of the most important and every year increasing problems in ofce workers (Cagnie et al., 2013). Purpose. To determine the relationship between functional state of cervical spine, fear of movement and neck-shoulder muscle pain threshold in ofce workers in the aspect of gender. Methods. Thirty six individuals voluntarily participated in the research (21 females, 15 males), who met inclusions criteria. We assessed subjective functional state of cervical spine, fear of movement and neck-shoulder muscle pain threshold on both sides. Results. Females had greater neck disability than males (females – 12.24 ± 3.75 scores, males – 11.27 ± 3.28 scores, p > 0.05) and felt more pain-induced fear of movement during work (females – 23.05 ± 3.72 scores, males – 21.8 ± 2.37 scores, p > 0.05). Males’ neck-shoulder muscle pain threshold on both sides was higher than that of females (p < 0.05). Conclusions. There was no difference between sedentary females and males’ neck disability and fear of movement. Sedentary males had signifcantly higher neck-shoulder muscle pain threshold compared to females. There were moderate correlations between male neck disability and right supraspinatus muscle pain threshold, but we did not fnd signifcant correlations between female results. There were moderate correlations between females’ fear of movement at work and left infraspinatus muscle pain threshold, while between males there were moderate correlations between fear of movement at work and both middle trapezius muscle and right infraspinatus muscle pain thresholds.Keywords: ofce workers, neck disability, fear of movement, neck-shoulder, pain threshold.

Background:Rheumatoid arthritis is a common type of autoimmune arthritis characterized by chronic inflammation. Cervical spine is often affected specially in long lasting diseaseObjectives:Evaluate efficacy of Third occipital nerve Radiofrequency under fluoroscopic guidance to treat refractory cervicogenic headache in RA patients.Methods:The current study was revised and approved from the local ethical committee of Faculty of Medicine; Assiut University, then registered in the clinical trials under the number ofNCT03852355. Inclusion criteria included, Patients who fulfilled the American College of Rheumatology (ACR) (2010) criteria for RA and suffering from upper neck pain and/or headache due to bilateral 3rd occipital nerve involvement, excluding other local cervical spine pathologies was confirmed by MRI and previously failed conservative treatment for at least three months prior to enrollment. Sixty adult patients were randomly assigned to one of the two studied groups Group 1 (RF, n = 30), received bilateral Third occipital nerve Radiofrequency under fluoroscopic guidance or Group 2 (control group, n = 30), received oral prednisolone 10 mg/day. The two groups were then followed-up with neck disability index (NDI), nocturnal neck pain VAS score and headache score every two weeks for three months. Sleep disturbance, sleep disability index were reassessed six months post intervention. Post interventional assessment was done by pain physician who were kept blind to the grouping process.Results:Neck disability index (1ry outcome), Nocturnal pain VAS, and severity of headache showed significant differences during the whole post-interventional study period. The patients in RF group demonstrated significant improvement of pain in comparison to baseline value over the whole six months with p-value < 0.001 as regard to the fore-mentioned three parameters. On the other aspect, the control group patients showed significant improvement in comparison to its baseline value after the 2nd, 12th and 24th weeks only as follows: (0.001,0.003, 0.003 for the NDI) (p values of 0.02,0.01, 0.01 for the nocturnal pain VAS), (0.001 0.009, 0.005 for the headache VAS severity.Conclusion:Radiofrequency of 3rd occipital nerve is effective in treatment of refractory cervicogenic headache in RA.Disclosure of Interests: :None declared

Svensson, Peter, Satoshi Minoshima, Ahmad Beydoun, Thomas J. Morrow, and Kenneth L. Casey. Cerebral processing of acute skin and muscle pain in humans. J. Neurophysiol. 78: 450–460, 1997. The human cerebral processing of noxious input from skin and muscle was compared with the use of positron emission tomography with intravenous H2 15O to detect changes in regional cerebral blood flow (rCBF) as an indicator of neuronal activity. During each of eight scans, 11 normal subjects rated the intensity of stimuli delivered to the nondominant (left) forearm on a scale ranging from 0 to 100 with 70 as pain threshold. Cutaneous pain was produced with a high-energy CO2 laser stimulator. Muscle pain was elicited with high-intensity intramuscular electrical stimulation. The mean ratings of perceived intensity for innocuous and noxious stimulation were32.6 ± 4.5 (SE) and 78.4 ± 1.7 for cutaneous stimulation and 15.4 ± 4.2 and 73.5 ± 1.4 for intramuscular stimulation. The pain intensity ratings and the differences between noxious and innocuous ratings were similar for cutaneous and intramuscular stimuli ( P > 0.05). After stereotactic registration, statistical pixel-by-pixel summation ( Z score) and volumes-of-interest (VOI) analyses of subtraction images were performed. Significant increases in rCBF to both noxious cutaneous and intramuscular stimulation were found in the contralateral secondary somatosensory cortex (SII) and inferior parietal lobule [Brodmann area (BA) 40]. Comparable levels of rCBF increase were found in the contralateral anterior insular cortex, thalamus, and ipsilateral cerebellum. Noxious cutaneous stimulation caused significant activation in the contralateral lateral prefrontal cortex (BA 10/46) and ipsilateral premotor cortex (BA 4/6). Noxious intramuscular stimulation evoked rCBF increases in the contralateral anterior cingulate cortex (BA 24) and subsignificant responses in the contralateral primary sensorimotor cortex (MI/SI) and lenticular nucleus. These activated cerebral structures may represent those recruited early in nociceptive processing because both forms of stimuli were near pain threshold. Correlation analyses showed a negative relationship between changes in rCBF for thalamus and MI/SI for cutaneous stimulation, and positive relationships between thalamus and anterior insula for both stimulus modalities. Direct statistical comparisons between innocuous cutaneous and intramuscular stimulation with the use of Z scores and VOI analyses showed no reliable differences between these two forms of noxious stimulation, indicating a substantial overlap in brain activation pattern. The comparison of noxious cutaneous and intramuscular stimulation indicated more activation in the premotor cortex, SII, and prefrontal cortex with cutaneous stimulation, but these differences did not reach statistical significance. The similar cerebral activation patterns suggest that the perceived differences between acute skin and muscle pain are mediated by differences in the intensity and temporospatial pattern of neuronal activity within similar sets of forebrain structures.
