“…In current study, we observed a significant lower GMV in patients with DCM, indicating that DCM patients might be more sensitive to pain. These results were not surprising and in line with previous study that the majority of the patients suffered from persistent pain which further modified the central nervous system (e.g., central sensitization), and accountable for variations in pain sensitivity [ 36 – 39 ]. Further, we also observed significant lower precuneus GMV in patients with PAP than those without, suggesting pain hypersensitivity in PAP patients.…”

Objective To investigate the brain structural correlates of postoperative axial pain (PAP) in degenerative cervical myelopathy (DCM) following posterior cervical decompression surgery. Methods Structural images with high-resolution T1 weighting were collected from 62 patients with DCM and analyzed, in addition to 42 age/gender matched subjects who were healthy. Voxel-based morphometry (VBM) was analyzed, grey matter volume (GMV) was computed. One-way ANOVA was performed to reveal the GMV differences among DCM patients with PAP, patients without PAP and healthy controls (HC). Post-hoc analyses were conducted to identify the pair-wise GMV differences among these three groups. Analyses of correlations were conducted to uncover the link between clinical measurements and GMV variations. Last, support vector machine (SVM) was conducted to test the utility of GMV for classifying PAP and nPAP DCM patients. Results Three main findings were observed: [1] Compared to healthy controls, DCM patients showed a significantly lower GMV in the precuneus preoperatively. DCM patients with PAP also exhibited a lower GMV within precuneus than those without; [2] In DCM patients with PAP, the precuneus GMV was inversely related to the postoperative pain intensity; [3] Moreover, successful classification between PAP and nPAP were observed via SVM based on precuneus GMV as features. Conclusion In summary, our results indicate that precuneus GMV may be linked to PAP in DCM, and could be employed to forecast the emergence of PAP in DCM patients.

“…Pressure pain threshold (PPT) was assessed using a handheld algometer at up to four different anatomical locations [43,44,60,61,64,72,73]. The PPT was conducted using a push force gauge whereby pressure applied over a particular muscle or tissue is increased until the patient describes the pressure as becoming painful.…”

Central sensitisation is assumed to be one of the underlying mechanisms for chronic low back pain. Because central sensitisation is not directly assessable in humans, the term ‘human assumed central sensitisation’ (HACS) is suggested. The objectives were to investigate what definitions for HACS have been used, to evaluate the methods to assess HACS, to assess the validity of those methods, and to estimate the prevalence of HACS. Database search resulted in 34 included studies. Forty different definition references were used to define HACS. This review uncovered twenty quantitative methods to assess HACS, including four questionnaires and sixteen quantitative sensory testing measures. The prevalence of HACS in patients with chronic low back pain was estimated in three studies. The current systematic review highlights that multiple definitions, assessment methods, and prevalence estimates are stated in the literature regarding HACS in patients with chronic low back pain. Most of the assessment methods of HACS are not validated but have been tested for reliability and repeatability. Given the lack of a gold standard to assess HACS, an initial grading system is proposed to standardize clinical and research assessments of HACS in patients with a chronic low back.

“…According to this paradigm, each ailment has a single underlying cause, and if that cause is addressed, the patient will be restored tohealth. 7 CLBP's bio psychosocial paradigm acknowledges that cognitive, emotional, psychological, behavioral, physical, and social components all interact to perpetuate pain, and that these factors can all be treated with integrated multimodal therapy. Since no single model has been shown to be superior to the others, it is advised that the most effective way to employ these models is to use the right components of each in accordance with the unique needs of individual patients rather than to follow one specific model.…”

Background: Chronic low back pain is a very common symptom in populations everywhere and is responsible for more years lived with disability world wide than any other condition. It is a main cause of activity limitation and work absence, moreover, reduced mobility can lead to significant alterations inquality of life in the longterm.Objective: To find out the effect of pain education on Quality of life of chronic low back pain patients.Methodology: Forth is study 40 subjects with chroniclow backpain who fulfill these lection criteria were recruited. Subjects have been divided into 2 groups based on simple random sampling (Lottery Method). Group A (Experimental Group) received pain education along with conventional exercises. Group B (Control Group) received only conventional exercises.Both groups received intervention for about 4 weeks with each session 45 minutes.Result: Participantsin both groups experienced reduction in pain,fear, disability and improvement in Quality of life. Conclusion:The results of this study concluded that there was no significant difference between pain education group and conventional exercise group.
