EFFECTIVENESS OF GRADED MOTOR IMAGERY IN MUSCULOSKELETAL DISORDERS: A REVIEW OF LITERATURE

ABSTRACT Musculoskeletal disorders pose a significant global health burden with a substantial impact on individuals and healthcare systems. Graded Motor Imagery (GMI) is a novel and emerging approach in musculoskeletal rehabilitation based on the principles of neuroplasticity. This literature review aimed to evaluate the available evidence for the efficacy of GMI in diverse musculoskeletal pathologies. GMI is a multicomponent rehabilitation strategy that includes laterality recognition, motor imagery, and mirror therapy. It is hypothesized that the overall GMI program aims to create neural adaptations, reduce pain, and reduce disability. This review evaluated the effects of GMI from Randomized Controlled Trials on pain reduction, pain-related disability, strength, physical function, and fear of movement. Keywords: Graded Motor Imagery (GMI), Neuroplasticity, Musculoskeletal rehabilitation, Pain reduction, Randomized Controlled Trials (RCTs).

Associations between pain intensity, psychosocial factors, and pain-related disability in 4285 patients with chronic pain

Pain, a widespread challenge affecting daily life, is closely linked with psychological and social factors. While pain clearly influences daily function in those affected, the complete extent of its impact is not fully understood. Given the close connection between pain and psychosocial factors, a deeper exploration of these aspects is needed. In this study, we aim to examine the associations between psychosocial factors, pain intensity, and pain-related disability among patients with chronic pain. We used data on 4285 patients from the Oslo University Hospital Pain Registry, and investigated pain-related disability, pain intensity, pain catastrophizing, psychological distress, perceived injustice, insomnia, fatigue, and self-efficacy. We found significant associations between all psychosocial variables and pain-related disability, even after adjusting for demographic factors. In the multiple regression model, sleep problems and pain intensity were identified as primary contributors, alongside psychological distress, and fatigue. Combined, these factors accounted for 26.5% of the variability in pain-related disability, with insomnia and pain intensity exhibiting the strongest associations. While the direction of causation remains unclear, our findings emphasize the potential of interventions aimed at targeting psychosocial factors. Considering the strong link between psychosocial factors and pain-related disability, interventions targeting these factors—particularly insomnia—could reduce disability and enhance quality of life in those who suffer.

Internet-Delivered Psychological Pain Management: A Prospective Cohort Study Examining Routine Care Delivery by a Specialist Regional Multidisciplinary Pain Service

Several clinical trials have demonstrated the effectiveness of internet-delivered psychological-based pain management programs (PMPs). However, to date, no large studies have reported the outcomes of PMPs when delivered by specialist multidisciplinary pain services in routine care. The present study reports (n = 653) the outcomes of an internet-delivered PMP provided as routine care by a specialist Australian regional pain service over a 6-year period. High levels of treatment commencement (85%) and completion (72%) were observed, with more than 80% of patients reporting they were satisfied with the intervention. Clinical improvements were observed from pretreatment to post-treatment (% change, 95% confidence intervals (CI)) in pain-related disability (8.8%; 4.5, 12.8), depression (28.4%; 23.0, 33.4), anxiety (21.9%; 14.6, 28.5), and pain intensity (7%; 3.5, 10.5), which were maintained to 3-month follow-up. At 3-month follow-up, 27% (23, 31), 46% (41, 51), 44% (39, 49), and 22% (19, 26) reported clinically meaningful (defined as ≥ 30%) improvements in pain-related disability, depression, anxiety, and pain intensity, respectively. These results were obtained with relatively little therapist time per patient (M = 30.0, (standard deviation) SD = 18.8) to deliver the intervention. The current findings highlight the potential of internet-delivered PMPs as part of the services provided by specialist pain services, particularly those servicing large geographical regions and for patients unable to travel to clinics for face-to-face care. PerspectiveThis study reports the outcomes of the routine delivery of an internet-delivered psychological PMP by a specialist pain service. The findings highlight the potential of this model of care when provided by specialist pain services, particularly for patients not unable to attend and not requiring intensive face-to-face care.

Supporting self-management of low back pain with an internet intervention with and without telephone support in primary care (SupportBack 2): a randomised controlled trial of clinical and cost-effectiveness

Low back pain is prevalent and a leading cause of disability. We aimed to determine the clinical and cost-effectiveness of an accessible, scalable internet intervention for supporting behavioural self-management (SupportBack). Participants in UK primary care with low back pain without serious spinal pathology were randomly assigned 1:1:1 using computer algorithms stratified by disability level and telephone-support centre to usual care, usual care and SupportBack, or usual care and SupportBack with physiotherapist telephone-support (three brief calls). The primary outcome was low back pain-related disability (Roland Morris Disability Questionnaire [RMDQ] score) at 6 weeks, 3 months, 6 months, and 12 months using a repeated measures model, analysed by intention to treat using 97·5% CIs. A parallel economic evaluation from a health services perspective was used to estimate cost-effectiveness. People with lived experience of low back pain were involved in this trial from the outset. This completed trial was registered with ISRCTN, ISRCTN14736486. Between Nov 29, 2018, and Jan 12, 2021, 825 participants were randomly assigned (274 to usual care, 275 to SupportBack only, 276 to SupportBack with telephone-support). Participants had a mean age of 54 (SD 15), 479 (58%) of 821 were women and 342 (42%) were men, and 591 (92%) of 641 were White. Follow-up rates were 687 (83%) at 6 weeks, 598 (73%) at 3 months, 589 (72%) at 6 months, and 652 (79%) at 12 months. For the primary analysis, 736 participants were analysed (249 usual care, 245 SupportBack, and 242 SupportBack with telephone support). At a significance level of 0·025, there was no difference in RMDQ over 12 months with SupportBack versus usual care (adjusted mean difference -0·5 [97·5% CI -1·2 to 0·2]; p=0·085) or SupportBack with telephone-support versus usual care (-0·6 [-1·2 to 0·1]; p=0·048). There were no treatment-related serious adverse events. The economic evaluation showed that the SupportBack group dominated usual care, being both more effective and less costly. Both interventions were likely to be cost-effective at a threshold of £20 000 per quality adjusted life year compared with usual care. The SupportBack internet interventions did not significantly reduce low back pain-related disability over 12 months compared with usual care. They were likely to be cost-effective and safe. Clinical effectiveness, cost-effectiveness, and safety should be considered together when determining whether to apply these interventions in clinical practice.

Effects of pain education on disability, pain, quality of life, and self-efficacy in chronic low back pain: A randomized controlled trial.

Low back pain stands as a prevalent contributor to pain-related disability on a global scale. In addressing chronic low back pain (CLBP), there is a growing emphasis on incorporating psychological strategies into the management process. Among these, pain education interventions strive to reshape pain beliefs and mitigate the perceived threat of pain. This randomized controlled trial sought to assess the effects of pain education on various aspects, including pain levels, disability, quality of life, self-efficacy, and prognostic characteristics in individuals grappling with CLBP. The clinical trial, retrospectively registered with the Clinical Trials Registry of India (CTRI/2021/08/035963), employed a two-arm parallel randomized design. Ninety-two participants with CLBP were randomly assigned to either the standard physiotherapy care with a pain education program or the control group. Both groups underwent a 6-week intervention. Assessment of pain intensity (using NPRS), disability (using RMDQ), self-efficacy (using the general self-efficacy scale), and well-being (using WHO 5I) occurred both before and after the 6-week study intervention. Post-intervention score comparisons between the groups revealed that the pain education intervention led to a significant reduction in disability compared to the usual standard care at 6 weeks (mean difference 8.2, p < 0.001, effect size Cohen d = 0.75), a decrease in pain intensity (mean difference 3.5, p < 0.001, effect size Cohen d = 0.82), and an improvement in the well-being index (mean difference 13.7, p < 0.001, effect size Cohen d = 0.58). The findings suggest that integrating a pain education program enhances the therapeutic benefits of standard physiotherapy care for individuals dealing with chronic LBP. In conclusion, the clinical benefits of pain education become apparent when delivered in conjunction with standard care physiotherapy during the management of chronic low back pain.

Examining tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy: stakeholder preference and recommendations for modification

PurposeTo firstly identify tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy (CP), and secondly identify suggestions to improve their relevance, comprehensiveness, comprehensibility and feasibility for the CP population. Improving assessment of the impact of pain on emotional functioning can enhance quality of life by improving access to interventions for pain-related physical disability, anxiety and depression.MethodsEthics approval was granted through the Women’s and Children’s Health Network Human Research Ethics Committee (2022/HRE00154). A mixed methods study with people with lived experience and clinicians, and guided by the Consensus-based Standards for Measurement Instruments (COSMIN), was undertaken. An online survey identified the highest rated tools for validation and/or modification for young people with CP and chronic pain. Focus groups and interviews investigated content validity and feasibility of the tools identified as highest rated.ResultsThe Fear of Pain Questionnaire for Children-SF (FOPQ-C-SF) and Modified Brief Pain Inventory (mBPI) were the highest rated for pain coping and multidimensional assessment (respectively) from the online survey (n = 61) of eight tools presented. Focus group and interview data (n = 30), including 58 unique modification suggestions, were coded to six categories: accessibility, comprehensibility, feasibility, relevance, presentation and comprehensiveness.ConclusionPotential modifications have been identified to improve the appropriateness and feasibility of the FOPQ-C-SF and mBPI for children and young people with CP. Future research should implement and test these modifications, prioritising the involvement of people with lived experience to ensure their needs are met alongside clinicians.

The experiences of people living with obesity and chronic pain: A Qualitative Evidence Synthesis (QES) protocol.

There is a substantial and progressive association between chronic pain (CP) and living with overweight or obesity. The relationship between obesity and CP is intricate and complex, with obesity being associated with increased pain-related disability, pain intensity, reduction in physical functioning and poorer psychological well-being. A Qualitative Evidence Synthesis (QES) provides an opportunity to better understand and reveal key areas within the patient experience of these complex interactions to inform best practice and future intervention design. The aim of this QES is to methodically and systematically review and synthesise the qualitative literature reporting on the personal experiences of people who are both living with obesity (PwO) and chronic pain. The phenomenon of interest of this QES is the lived experiences of PwO and CP. The following research question was developed using a modified Population, Intervention, Comparison, Outcome and Study type (PICOS) framework: "What are the lived experiences of people living with obesity and chronic pain?". One review author will conduct a systematic search based on keywords and Medical Subject Headings (MeSH) terms for finding relevant articles in five peer-review databases, from inception to the date of searching. Two review authors will independently apply inclusion and exclusion criteria and screen articles in a two-stage process. The methodological quality of included studies will be assessed using the Critical Appraisal Skills Programme (CASP) tool and data will be extracted using a customised template. We will undertake a thematic synthesis of qualitative data from included studies and report our findings narratively. Confidence in the findings will be assessed based on the Grading of Recommendations Assessment, Development and Evaluation Confidence in Evidence from Reviews of Qualitative Research (GRADE-CER-Qual) approach. This study will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) and Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. It is anticipated that the findings of the review will facilitate a deep and broad understanding of the complex interactions between CP and obesity and will help inform best practice and future intervention design. Findings will be disseminated through journals that undergo peer review, presentations at conferences, engagement with public and patient advocacy groups, and social media. Ethical approval is not required to conduct this review. PROSPERO registration number: CRD42023361391.

Repetitive transcranial magnetic stimulation focusing on patients with neuropathic pain in the upper limb: a randomized sham-controlled parallel trial

This study aimed to evaluate the efficacy and safety of navigation-guided repetitive transcranial magnetic stimulation (rTMS) over the primary motor cortex in patients with neuropathic pain in the upper limb. This randomized, blinded, sham-controlled, parallel trial included a rTMS protocol (10-Hz, 2000 pulses/session) consisting of five daily sessions, followed by one session per week for the next seven weeks. Pain intensity, as well as pain-related disability, quality of life, and psychological status, were assessed. For the primary outcome, pain intensity was measured daily using a numerical rating scale as a pain diary. Thirty patients were randomly assigned to the active rTMS or sham-stimulation groups. In the primary outcome, the decrease (least square [LS] mean ± standard error) in the weekly average of a pain diary at week 9 compared to the baseline was 0.84 ± 0.31 in the active rTMS group and 0.58 ± 0.29 in the sham group (LS mean difference, 0.26; 95% confidence interval, − 0.60 to 1.13). There was no significant effect on the interaction between the treatment group and time point. Pain-related disability score improved, but other assessments showed no differences. No serious adverse events were observed. This study did not show significant pain relief; however, active rTMS tended to provide better results than sham. rTMS has the potential to improve pain-related disability in addition to pain relief.Clinical Trial Registration number: jRCTs052190110 (20/02/2020).

Augmented Central Pain Processing Occurs after Osteoporotic Vertebral Compression Fractures and Is Associated with Residual Back Pain after Percutaneous Vertebroplasty.

A retrospective analysis. To investigate the occurrence of central sensitization (CS) in patients with osteoporotic vertebral compression fractures (OVCFs) and identify the association between CS and residual back pain (RBP). RBP is a vexing complication that affects 6.3%-17.0% of patients with OVCFs who underwent percutaneous vertebroplasty (PVP). Given the negative effect of RBP on patients' psychological and physiological statuses, efforts to preoperatively select patients who are at risk for RBP development have a high priority to offer additional treatment and minimize this complication. Preoperatively, all 160 patients with OVCFs underwent pressure-pain threshold (PPT), temporal summation (TS), conditioned pain modulation (CPM), and imaging assessments. Pain intensity and pain-related disability were evaluated before and after PVP. Preoperatively, patients with OVCFs had lower PPTs in both local pain and pain-free areas and lower CPM and higher TS in pain-free areas than healthy participants (p<0.05). Unlike patients with acute fractures, patients with subacute/chronic OVCFs showed higher TS with or without lower CPM in the pain-free area compared with healthy participants (p<0.05). Postoperatively, RBP occurred in 17 of 160 patients (10.6%). All preoperative covariates with significant differences between the RBP and non-RBP groups were subjected to multivariate logistic regression, showing that intravertebral vacuum cleft, posterior fascia edema, numeric rating pain scale scores for low back pain at rest, and TS were independently associated with RBP (p<0.05). Augmented central pain processing may occur in patients with OVCFs, even in the subacute stage, and this preexisting CS may be associated with RBP. Preoperative assessment of TS in pain-free areas may provide additional information for identifying patients who may be at risk of RBP development, which may be beneficial for preventing this complication.

Surgical options in thoracic disc herniation: Evaluating long-term outcomes of 21 cases based on a single-center 10-year experience.

Symptomatic thoracic disc herniation (TDH) is a rare pathology that is addressed with relatively challenging surgical approaches, the choice and technical execution of which have been well described in the literature. Interestingly, long-term outcomes, including surgical site pain-related disability, the need for instrumentation, and commonly occurring complications such as cerebrospinal fluid (CSF)-pleural fistula have not been widely addressed. Here, we address the complication profiles and long-term outcomes of different surgical approaches for TDH. We conducted a retrospective review of 21 consecutive patients who underwent surgery for TDH between 2000 and 2010. We assessed post-operative complications such as CSF-pleural fistulas, as well as long-term outcomes using Frankel grades, the EQ-5D-3L, and the Visual Analog Scale. We also looked at the need for instrumentation postoperatively. 21 consecutive patients (13 females, 8 males) with a mean age of 55.3 years (Standard deviation 8.1) underwent thoracic discectomy for symptomatic TDH. Surgical approaches included posterolateral thoracotomy (52%, n = 11), costotransversectomy (43%, n = 9), and transpedicular (5%, n = 1). Herniations were classified as soft (38%, n = 8), calcified (38%, n = 8), or calcified-transdural (24%, n = 5). Postoperatively, all patients with calcifiedtransdural herniations undergoing posterolateral thoracotomy (100%, n = 5) developed CSF-pleural fistulas, which resolved spontaneously without the need for surgical re-exploration. 89% (n = 16) of patients exhibited sustained improvement in Frankel scores. Persistent wound site pain was reported by 50% (n = 7) of patients. Despite favorable neurological outcomes, patients with symptomatic TDHs can experience long-term surgical site pain, and therefore, a move toward minimally invasive exposure in such cases should be considered. Postoperative complications such as CSF-pleural fistulas are unlikely to require surgical intervention and thus can be managed conservatively.

Care ally-assisted massage for Veterans with chronic neck pain: TOMCATT results

PurposeChronic neck pain (CNP) is prevalent and challenging to treat. Despite evidence of massage's effectiveness for CNP, multiple accessibility barriers exist. The Trial Outcomes for Massage: Care Ally-Assisted vs. Therapist Treated (TOMCATT) study examined a care ally-assisted massage (CA-M) approach compared to a waitlist control prior to a study design modification (WL-C0). MethodsCA-M consisted of in-person training for veteran/care-ally dyads to learn a standardized 30-minue massage routine, instructional DVD, and printed treatment manual. Participants were to complete three care ally-assisted massage sessions weekly for 12-weeks. Outcomes collected at baseline, 1-, 3-, and 6-months included validated measures of neck pain severity and associated disability. Linear mixed-model approaches were used for analysis with 3-months as the primary outcome timepoint. ResultsParticipants (N = 203) were 56.7 ± 14 years old, 75% White, 15% female, and 75% married/partnered. Among 102 CA-M participants, 45% did not attend the in-person training and subsequently withdrew from the study and were more likely to be younger (p = .016) and employed (p = .004). Compared to WL-C0, CA-M participants had statistically significant reductions in pain-related disability at 3-months (−3.4, 95%CI = [−5.8, −1.0]; p = .006) and 6-months (−4.6, 95%CI = [−7.0, −2.1]; p < .001) and pain severity at 3-months (−1.3, 95%CI = [−1.9, −0.8]; p < .001) and 6-months (−1.0, 95%CI = [−1.6, −0.4]; p = .007), respectively. ConclusionIn this analysis, CA-M led to greater reductions in CNP with disability and pain severity compared to WL-C0, despite treatment engagement and retention challenges. Future work is needed to determine how to better engage Veterans and their care-allies to attend CA-M training.

An Interdisciplinary Multimodal Integrative Healthcare Program for Chronic Spinal Pain and Comorbid Mental Disorders.

Previous studies evaluating interdisciplinary multimodal interventions for chronic spinal pain often excluded patients with comorbid mental disorders. This study aims to assess the effectiveness of an outpatient secondary care interdisciplinary multimodal integrative healthcare program for individuals experiencing co-occurring chronic spinal pain and mental disorders. Participants were 944 patients with chronic spinal pain and comorbid mental disorders. Primary outcomes were health-related quality of life, assessed using the Research and Development-36 (RAND-36), and pain-related disability, assessed using the Quebec Back Pain Disability Scale (QBPDS). Secondary outcomes included pain intensity, pain catastrophizing, kinesiophobia, fatigue, lumbar mobility, and isometric strength. Data were collected during the healthcare program at four time points: pretreatment (T0), midway through 20-week treatment (T1), end of 20-week treatment (T2), and at completion of 12-month relapse prevention program (T3). Multilevel regression analyses were conducted to examine the effects of the healthcare program on primary outcomes over time. The 20-week treatment period yielded significant improvements in both mental ( B = 0.44, t (943) = 19.42, p < .001) and physical component summary scores ( B = 0.45, t (943) = 18.24, p < .001) of the RAND-36, as well as in QBPDS total score ( B = -0.77, t (943) = -26.16 p < .001). Pretreatment scores indicated the presence of problematic fatigue, kinesiophobia, and clinical levels of pain catastrophizing, all of which resolved by the end of the 12-month relapse prevention program. An interdisciplinary multimodal integrative healthcare program seems effective for patients with chronic spinal pain and comorbid mental disorders.

Partner-Caregivers’ Interpretation Bias and Sexual Satisfaction: Gender and Congruency in Pain-Related Beliefs

It has been suggested that family caregivers of chronic pain patients may develop cognitive biases similar to those observed among patients in previous studies. However, there is a gap in knowledge regarding the effect of such biases on patients’ adaptation to pain. In this study, we examined the relationship between partner-caregivers’ interpretation bias and sexual satisfaction among married heterosexual couples. We further examined the relationship between caregivers’ interpretation bias and congruency in the beliefs that patients and caregivers hold about the experience of pain. The sample comprised 32 married couples in a caregiving relationship and 28 married individuals who were neither patients nor caregivers, serving as control participants. Caregivers and controls completed a modified version of the interpretation bias task. Patients and caregivers filled out the Sexual Satisfaction Index and a Patient’s Pain-Related Disabilities Checklist. Results confirmed that a biased negative interpretation exists among caregivers when compared to partners of pain-free individuals. A noticeable gender effect was observed in the effect of interpretation bias on patients’ sexual satisfaction. Female partner-caregivers’ negative interpretation bias was associated with a lower level of sexual satisfaction among male patients. In contrast, the same bias was associated with higher levels of sexual satisfaction among female patients when observed among male partner-caregivers. Furthermore, a moderate but not symmetrical positive interpretation was associated with higher levels of congruence on the level of patients’ disability within couples. The findings are another step toward incorporating the social circuit of individuals with chronic pain conditions into intervention protocols.

Stretching to Reduce Pain-Related Disability Among Echocardiographic and Interventional Laboratory Employees-A Pilot Study.

Stretching improves range of motion and changes the viscoelastic properties of muscle-tendon units. We hypothesized that a regular stretching program would reduce the functional consequences of pain for employees working in echocardiographic, ultrasound, and interventional laboratories. This exploratory, proof-of-concept study was meant to inform expectations for future randomized, controlled studies. In this unblinded, nonrandomized, observational study, we enrolled 196 health care professionals working in the interventional and echocardiographic laboratories in the departments of cardiology and radiology at Mayo Clinic and Mayo Clinic Health System to perform 15-minute neck, upper extremity, low back, and lower extremity stretches for 1 year. The functional consequences of pain were self-reported by using the Disability of Arm, Shoulder, and Hand; Neck Disability Index; and Roland-Morris Questionnaire, which was administered at baseline and at 1 year to measure response to stretching. Monitoring with an assessment plan for injuries was undertaken. Employees who were pregnant, unable to do exercises, or under active orthopedic treatment, were excluded. Of the 196 enrolled, 68 (35%) provided complete data at both baseline and follow-up. The majority of participants were over 40 years (n = 51; 72%) and female (n = 51; 72%). Participants performed stretches for 120.5 (IQR, 52-184) days over the year. The number of days of doing the stretches was well distributed across the study period with median quarters 1, 2, 3, and 4 of 32 (19-51), 32 (20-51), 31 (17-45), and 32.5 (12-47) days, respectively. The majority of participants (52.3%) stretched before, 18.9% stretched during and 28.8% stretched after work. Self-reported upper extremity disability improved in the treatment group with a significant decrease in the median Disability of Arm, Shoulder, and Hand score (5.2 to 2.6; P = .002). There was an absolute 4% decrease in the Neck Disability Index score, between baseline and 1-year follow-up (10% to 6%, P = .017). There was not a significant change in the Roland-Morris Questionnaire from baseline to follow-up (1 to 0; P = .287). No participant reported any stretch-related injuries. A routine stretching program may represent an attractive, low-cost, noninvasive option to reduce upper extremity musculoskeletal disability of employees working in the echocardiographic, ultrasound, and interventional laboratories. Larger randomized trials are needed to confirm the association.

350 Surgical Treatment of Refractory Low Back Pain Using BurstDR Capable Spinal Cord Stimulation (SCS) in Patients Without Options for Corrective Surgery; 12-month Results From a Paddle Lead Cohort

INTRODUCTION: DISTINCT is a randomized controlled trial evaluating passive recharge burst SCS compared to CMM in improving pain and pain-related physical function in patients suffering from chronic back pain without prior lumbar surgery, and for whom corrective surgery is not an option. Sub analysis of outcome measures are presented for subjects implanted with paddle leads at both 6 and 12 months. METHODS: An independent board-certified spine surgeon reviewed each case confirming a lack of corrective surgical options. Out of 29 sites and 115 implants, 10 sites implanted 50 subjects with paddle leads. Primary and secondary endpoints assessed improvements in low back pain intensity (NRS), low back pain-related disability (ODI), pain catastrophizing (PCS), and patient global impression of change (PGIC). RESULTS: Data are available for 47 and 44 subjects at 6 and 12 months respectively. Subjects reported significant reductions in pain relief at 6 and 12 months, decreasing from 7.8 ± 1.2 at baseline to 2.0 ± 1.6 and 2.2 ± 2.2 respectively (p &lt; 0.0001). Disability was substantially (&lt; 20 points) reduced from severe to mild at 6 and 12 months; ODI reduced from 54.4 ± 15.0 at baseline to 19.9 ± 14.1 and 22.1 ± 13.6 respectively (p &lt; 0.0001). Pain catastrophizing improved to reflect the average of a non-chronic pain population; decreased from 27.6 ± 13.1 at baseline to 8.1 ± 8.2 and 7.8 ± 9.9 (p &lt; 0.0001). 76% report definite and meaningful improvements on PGIC. One lead related event was reported and resolved by repositioning CONCLUSIONS: Passive recharge bursts using paddle leads provide substantial relief to patients suffering from severe, debilitating, NSLBP. Patients report dramatic improvements in pain, function, and pain-related emotional distress. In addition, the rate of adverse events is low supporting a favorable safety profile.

Impact of Musculoskeletal Pain on Health-Related Quality of Life Among Adults in Saudi Arabia.

Background Musculoskeletal pain (MSP) is widely recognized as a prevalent public health issue that affects individuals of various genders and age groups. The aim of this study is to assess the influence of musculoskeletal pain on the quality of life (QoL)of adult individuals living in Saudi Arabia. Method This is a cross-sectional study using an online-administered questionnaire that was distributed via online platforms in Saudi Arabia for the duration between January and August 2023. Three questionnaire instruments were used in this study. The 36-item Short Form Health Survey questionnaire (SF-36), The 5-level EQ-5D version (EQ-5D-5L), and Roland-Morris Disability Questionnaire. Binary logistic regression analysis was used to identify predictors of better QoL and having mild to moderate disability. Results A total of 8359 participants were involved in this study. The most commonly reported sites of musculoskeletal pain were the lower back, neck, and shoulder, accounting for 36.8% (n= 3072), 30.5% (n= 2549), and 30.1% (n= 2514), respectively. The mean pain score for the study participants was 4.3 (SD: 2.3), which indicates mild degree of pain. The median EQ-5D-5L index value for the study participants was 0.827 (0.756-1.00), which demonstrates a high quality of life. The mean SF-36 score for the study participants was 63.11 (17.4), which demonstrates moderate quality of life. The median Roland-Morris Disability score for the study participants was 1.00 (0.00-7.00), which demonstrates a low level of pain-related disability. Male gender, younger age (30-39 years), having higher education attainment, having higher monthly income (more than SAR 20000), and having lower BMI (less than 25.8 kg/cm2) were predictors of better QoL (p<0.05). Conclusion Musculoskeletal pain is a multifactorial condition influenced by structural, physical, psychological, social, lifestyle, and comorbid health elements. It ranges from acute to chronic pain and, despite rarely being fatal, has a significant impact on QoL. Musculoskeletal discomfort varies in terms of intensity, affected regions, and demographic and lifestyle factors. This study sheds light on the multifaceted nature of MSP, its impact on QoL, and the significance of early intervention and individualized management strategies to improve the QoLof those affected.

Comparison of Cervical Biportal Endoscopic Spine Surgery and Anterior Cervical Discectomy and Fusion in Patients with Symptomatic Cervical Disc Herniation.

Background: We aimed to analyze the clinical outcomes and effectiveness of cervical biportal endoscopic spine surgery (C-BESS) and anterior cervical discectomy and fusion (ACDF) in patients with symptomatic cervical disc herniation. Methods: This study was a retrospective chart review of four-year clinical data involving 318 cases of symptomatic cervical disc herniation, with 156 patients undergoing the ACDF and 162 patients receiving the C-BESS. Preoperative and postoperative one-year data were collected. Results: The numeric rating scale and neck disability index showed statistically significant improvement for both ACDF and C-BESS groups. While showing a longer operation time and more blood loss during surgery compared to the ACDF group, the C-BESS group demonstrated a learning effect as the surgeon's proficiency increased with more cases. There was no significant difference in the postoperative length of hospitalization between the two methods. The subgroup with predominant arm pain revealed the statistical difference in arm pain intensity changes between the two groups (p < 0.001). The rates of complication were 2.6% for the ACDF group and 1.9% for the C-BESS group. Conclusions: C-BESS and ACDF are effective surgical treatments for patients with symptomatic single-level cervical disc herniation in relieving relevant pain intensities and pain-related disabilities.

Online Exercise Programs for Chronic Nonspecific Neck Pain: A Randomized Controlled Trial Reveals Comparable Effects of Global, Local, and Combined Approaches.

Specific neck exercises are recommended in the rehabilitation of chronic nonspecific neck pain (CNNP). They are unfortunately often accompanied by acute pain flare-ups. Global exercises might be a beneficial addition, as they activate endogenous analgesia without overloading painful structures. However, it is still unclear which type of exercise is most effective. This randomized controlled trial was done to evaluate the effect of an online blended program of global and specific neck exercises, compared to programs including only 1 of both types of exercise. Forty-eight patients with CNNP were randomized into 3 groups. Online questionnaires were collected at baseline, at midtreatment, immediately after treatment, and at the 3-month follow-up. Quantitative sensory testing and actigraphy were assessed at baseline and after treatment. Linear mixed-model analyses were performed to evaluate treatment effects within and between groups. Neck pain-related disability after treatment was considered the primary outcome. No time × treatment interaction effects were found. All groups improved in neck pain-related disability, pain intensity, self-reported symptoms of central sensitization, local pain sensitivity, physical activity, and pain medication use. No effects were found on quality of life, sleep quality, depression, anxiety, stress, widespread pain sensitivity, health economics, or actigraphy measurements. A higher global perceived effect was reported after performing the blended program, compared to the other groups. A blended exercise program was not superior to the stand-alone programs in reducing disability. Nevertheless, the global perceived effect of this type of exercise was higher. Future research necessitates larger sample sizes to adequately explore the optimal type of exercise for patients with CNNP. Exercise therapy should be an important part of the rehabilitation of patients with CNNP, regardless of the type of exercise.

Acupuncture for pain and pain-related disability in deep infiltrating endometriosis.

To evaluate the efficacy of acupuncture in relieving symptoms (dysmenorrhea, dyspareunia, pelvic pain and dyschezia) intensity, improving functional disability, reducing the number of days per months of dysmenorrhea, the frequency and the efficacy of analgesic use in deep infiltrating endometriosis (DIE). The safety profile was also evaluated. The study sample was 34 patients with DIE; for 2 months (T-2, T-1) the women recorded diary notes on the numbers of days of menstruation, the presence, intensity, and disability related to dysmenorrhea, dyspareunia, pelvic pain, and dyschezia. They then received a total of 15 acupuncture treatments over 6 months (T1-T6; once a week for 12 weeks, then once a month for 3 months). Dysmenorrhea intensity was decreased during treatment. A decrease of at least 50% in number of days of dysmenorrhea, and a decrease in moderate-to-severe disability starting from T1 to T6 was recorded for 58.6% of patients. Dyspareunia intensity steadily decreased starting at T2; the percentage of women with moderate-to-severe disability declined from 73.3% at T-2, to 36.9% at T3, T4, and T5. A decrease in pelvic pain score was noted starting at T1; the percentage of disability decreased from 83.3% at T-2 to 33.3% at T3 and T6. The intensity of dyschezia decreased from T-2 to T3 and T4 and then increased slightly. Analgesic drug use was lower during treatment and its efficacy appeared to be greater. The limitations notwithstanding our study-findings show that acupuncture was safe and effective in reducing pain intensity and symptoms-related disability. Larger-scale studies are needed to compare acupuncture and pharmacotherapy for endometriosis-related pain.
