Abstract
A randomized, controlled clinical trial was conducted from 2022 to 2023 at a hospital specializing in Traditional Chinese Medicine in Shanghai. A total of 564 participants were allocated into control and intervention groups in order to determine the effectiveness of Shujing Tongdu massage on patients with chronic lesions or spinal disorders. No significant differences were observed in baseline characteristics between the groups; age, gender and condition type were all distributed in a comparable manner. Following the implementation of Shujing Tongdu massage therapy twice weekly for the duration of 12 weeks, intervention group exhibited noteworthy enhancements. Significantly, rate of lesion healing achieved in the intervention group increased by 30%, while it merely improved by 10% in the control group. The intervention group exhibited decrease in pain intensity from 6.5 to 4.2, whereas control group demonstrated comparatively smaller reduction from 6.7 to 6.0. Range of motion in the intervention group increased substantially from 45 to 60 degrees, whereas it increased from 44 to 46 degrees in the control group. In the intervention group, Quality of Life scores increased from 50 to 75, exceeding the increase of 58 in the control group. There was significant rise in the Mental Well-being Index for intervention group, from 60 to 80, in contrast to rise of 64 from 62 in the control group. Statistically significant outcomes were determined, establishing the massage therapy's efficacy. Mild discomfort and muscle soreness were the most frequent adverse effects in the intervention group, whereas vertigo was more prevalent in the control group. Based on the findings of this research, Shujing Tongdu massage therapy effectively promoted wound healing and mitigated symptoms associated with spinal disorders, indicating its potential as the supplementary therapeutic modality in clinical environments.

Abstract
BACKGROUND Spinal disorders affect millions of people worldwide, and can cause significant disability and pain. The paraspinal muscles, located on either side of the spinal column, play a crucial role in the movement, support, and stabilization of the spine. Many spinal disorders can affect paraspinal muscles, as evidenced by changes in their morphology, including hypertrophy, atrophy, and degeneration. OBJECTIVES The objectives of this review were to examine the current literature on the relationship between the paraspinal muscles and spinal disorders, summarize the methods used in previous studies, and identify areas for future research. METHODS We reviewed studies on the morphological characteristics of the paravertebral muscle and discussed their relationship with spinal disorders, as well as the current limitations and future research directions. RESULTS The paraspinal muscles play a critical role in spinal disorders and are important targets for the treatment and prevention of spinal disorders. Clinicians should consider the role of the paraspinal muscles in the development and progression of spinal disorders and incorporate assessments of the paraspinal muscle function in clinical practice. CONCLUSION The findings of this review highlight the need for further research to better understand the relationship between the paraspinal muscles and spinal disorders, and to develop effective interventions to improve spinal health and reduce the burden of spinal disorders.

Abstract
OBJECTIVES To assess the impact of joint shape variations on inflammatory lesions on SI joint MRIs in patients with axial spondyloarthritis (axSpA). METHODS A total of 1194 patients from four different prospective cohorts were evaluated, with 684 (57.3%) having sufficient imaging data for inclusion (379 axSpA, 305 controls). All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. RESULTS Atypical joint forms were common in both axSpA (43.5% [154/354]) and control patients (44.2% [134/303]); both intra-articular variants and a crescent joint shape were significantly more common in axSpA patients (18.4% vs 11.6% and 11.0% vs 5.3.%, respectively; P < 0.001). The axSpA patients with intra-articular joint form variants had 2-fold higher odds of exhibiting erosions [odds ratio (OR) 2.09 (95% CI 1.18, 3.69)] and BMO [OR 1.79 (95% CI 1.13, 2.82)]; this association was not observed in controls. Accessory joints increased the odds for sclerosis in axSpA patients [OR 2.54 (95% CI 1.10, 5.84)] and for sclerosis [OR 17.91 (95% CI 6.92, 46.37)] and BMO [OR 2.05 (95% CI 1.03, 4.07)] in controls. CONCLUSIONS Joint form variations are associated with the presence of inflammatory lesions on SI joint MRIs of axSpA patients. This should be taken into consideration in future research on the interplay of mechanical strain and inflammation in axSpA.

Abstract
OBJECTIVE Clinical care pathways designed to triage spinal disorders have been shown to reduce wait times and improve patient satisfaction. The goal of this study was to perform an analysis of outpatient radiology costs before and after the implementation of a spine care triage pathway. METHODS All imaging orders and surgical procedures were captured in a prospective spine registry for patients referred to the department of neurosurgery within a single academic center between July 1, 2017, and November 3, 2020. A spine triage algorithm was developed and implemented January 1, 2018. Healthcare utilization was recorded for 1 year after the first appointment in the department of neurosurgery. Imaging costs were estimated using publicly available data from the Centers for Medicare and Medicaid Services. Statistical analysis consisted of an independent sample t-test or randomization test for continuous variables and a chi-square test for categorical variables. RESULTS A total of 3854 patients were included in this study. The mean age was 60 years (50.8% female) and 89.8% had undergone advanced imaging before being referred to the department of neurosurgery. In total, 12.6% of patients were referred with a specific surgical diagnosis (i.e., spinal stenosis, lumbar spondylolisthesis, etc.). During the pretriage phase 1810 patients were enrolled, and there were 2044 patients enrolled after the triage algorithm was implemented. Advanced imaging (CT or MRI) was ordered more frequently by providers before the triage program was initiated, with imaging ordered in 34% (617/1810) of patients pretriage versus 14.8% (302/2044) after the triage pathway was implemented (p < 0.001). The authors calculated a significant reduction in cost associated with reduced radiology utilization. Before triage, the cost of radiology utilization was $85,475/1000 patients compared with $40,107/1000 patients afterward (p < 0.001). The triage program did not change the utilization of surgery (14.6% before, 13.6% after). CONCLUSIONS Among patients treated after a spinal triage program was implemented in a single neurosurgery department, there was a substantial reduction in the use of advanced imaging and a 50% reduction in cost associated with outpatient radiology utilization. The triage program did not change the rate of spine surgery being performed.

Abstract
Activated microglia are involved in secondary injury after acute spinal cord injury (SCI) and in development of spinal cord-related neuropathic pain (NeP). The aim of the study was to assess expression of translocator protein 18 kDa (TSPO) as an indicator of microglial activation and to investigate visualization of the dynamics of activated microglia in the injured spinal cord using PET imaging with (R)-[11C]PK11195, a specific ligand for TSPO. In SCI chimeric animal models, TSPO was expressed mainly in activated microglia. Accumulation of (R)-[3H]PK11195 was confirmed in autoradiography and its dynamics in the injured spinal cord were visualized by (R)-[11C]PK11195 PET imaging in the acute phase after SCI. In clinical application of (R)-[11C]PK11195 PET/MRI of the cervical spinal cord in patients with NeP related to cervical disorders, uptake was found in cases up to 10 months after injury or surgery. No uptake could be visualized in the injured spinal cord in patients with chronic NeP at more than 1 year after injury or surgery, regardless of the degree of NeP. However, a positive correlation was found between standardized uptake value ratio and the severity of NeP, suggesting the potential of clinical application for objective evaluation of chronic NeP.

Abstract
Background Musculoskeletal spinal disorders significantly impact patient populations from everyday workers to military soldiers. Effective treatment is critical to minimize the time between injury and returning to work and daily activities. Injection of amniotic membrane/umbilical cord (AMUC) tissue has demonstrated great potential in reducing patients' pain and has become an increasingly popular treatment option for painful orthopedic disorders. Methods A single-center, retrospective study was conducted on patients diagnosed with musculoskeletal spinal disorders and subsequently treated with AMUC via epidural and facet injections. Demographics and outcomes related to pain were assessed. Pain was verbally reported by the patient on a scale of 0-10 where 0 indicated no pain and 10 indicated worst imaginable pain. Complications and adverse events were also reported. Results A total of 52 patients (average age 40.8 ± 9.6 years) were included in the analysis with diagnoses of spondylosis (n = 44), intervertebral disc degeneration (n = 31), radiculopathy (n = 18), stenosis (n = 2), or other conditions. The cohort's average baseline pain score was 4.9 ± 2.2 with a mean duration of symptoms for 54.2 months (range: 1-300 months). After AMUC injection, pain significantly decreased to 3.4 ± 2.3 at two weeks (p < 0.0001) and 3.5 ± 2.2 at 3-4 weeks (p = 0.0023). For the mean follow-up period of 10.6 ± 5.4 weeks, pain was reduced to 2.8 ± 2.1 (p < 0.0001 vs baseline). No significant complications or adverse events were reported. Conclusion Use of an injectable AMUC, such as CLARIX FLO, may alleviate pain in patients with painful spinal indications of various pathologies. This study provides further evidence of its safety and efficacy in epidural and facet injections. Further studies are warranted to verify these promising results.

Abstract
Determination of spine posture is of great interest for the effective prevention, evaluation, treatment and evolution monitoring of spinal disorders. Limitations of traditional imaging systems, including cost, radiation exposure (for X-ray based systems), projection volume issues and subject positioning requirements, etc., make non-invasive motion assessment tools effective alternatives for clinical and non-clinical use. In this work, a procedure was developed to obtain a subject-specific multibody model of the spine using either inertial or optical sensors and, based on this multibody model, to estimate the locations and orientations of the 17 vertebrae constituting the thoracolumbar spine. The number and calibration of the sensors, angular offsets, scaling difficulties and gender differences were addressed to achieve an accurate 3D-representation of the spine. The approach was validated by comparing the estimated positions of the sensors on 14 healthy subjects with those provided by an optical motion capture system. A mean position error of lower than 12 mm was obtained, thus showing that the proposed method can offer an effective non-invasive tool for the assessment of spine posture.

Abstract
Neck and back pain is increasingly prevalent, and has increased exponentially in recent years. As more resources are dedicated to the diagnosis of pain conditions, it is increasingly important that the diagnostic techniques used are as precise and accurate as possible. Traditional diagnostic methods rely heavily upon patient history and physical examination to determine the most appropriate treatments and/or imaging studies. Though traditional means of diagnosis remain a necessity, in many cases, correlation with positive or negative responses to injections may further enhance diagnostic specificity, and improve outcomes by preventing unnecessary treatments or surgeries. This narrative review aims to present the most recent literature describing the diagnostic validity of precision injections, as well as their impact on surgical planning and outcomes. Diagnostic injections are discussed in terms of facet arthropathy, lumbar radiculopathy, discogenic pain and discography, and sacroiliac joint dysfunction. There is a growing body of evidence supporting the use of diagnostic local anesthetic injections or nerve blocks to aid in diagnosis. Spinal injections add valuable objective information that can potentially improve diagnostic precision, guide treatment strategies, and aid in patient selection for invasive surgical interventions.

Abstract
Dorsal atlantoaxial stabilisation (DAAS) has mostly been described to treat atlantoaxial instability using low stiffness constructs in dogs. The aim of this study was to assess the feasibility and surgical outcome of a rigid cemented DAAS technique using bone corridors that have not previously been reported. The medical records of 12 consecutive dogs treated with DAAS were retrospectively reviewed. The method involved bi-cortical screws placed in at least four of eight available bone corridors, embedded in polymethylmethacrylate. Screw placement was graded according to their position and the degree of the breach from the intended bone corridor. All DAAS procedures were completed successfully. A total of 72 atlantoaxial screws were placed: of those, 51 (70.8%) were optimal, 17 (23.6%) were suboptimal, and 4 (5.6%) were graded as hazardous (including 2 minor breaches of the vertebral canal). Surgical outcome was assessed via a review of client questionnaires, neurological examination, and postoperative CT images. The clinical outcome was considered good to excellent in all but one case that displayed episodic discomfort despite the appropriate atlantoaxial reduction. A single construct failure was identified despite a positive clinical outcome. This study suggests the proposed DAAS is a viable alternative to ventral techniques. Prospective studies are required to accurately compare the complication and success rate of both approaches.

Abstract
Background The COVID-19 pandemic has greatly limited patients' access to care for spine-related symptoms and disorders. However, physical distancing between clinicians and patients with spine-related symptoms is not solely limited to restrictions imposed by pandemic-related lockdowns. In most low- and middle-income countries, as well as many underserved marginalized communities in high-income countries, there is little to no access to clinicians trained in evidence-based care for people experiencing spinal pain. Objective The aim of this study is to describe the development and present the components of evidence-based patient and clinician guides for the management of spinal disorders where in-person care is not available. Methods Ultimately, two sets of guides were developed (one for patients and one for clinicians) by extracting information from the published Global Spine Care Initiative (GSCI) papers. An international, interprofessional team of 29 participants from 10 countries on 4 continents participated. The team included practitioners in family medicine, neurology, physiatry, rheumatology, psychology, chiropractic, physical therapy, and yoga, as well as epidemiologists, research methodologists, and laypeople. The participants were invited to review, edit, and comment on the guides in an open iterative consensus process. Results The Patient Guide is a simple 2-step process. The first step describes the nature of the symptoms or concerns. The second step provides information that a patient can use when considering self-care, determining whether to contact a clinician, or considering seeking emergency care. The Clinician Guide is a 5-step process: (1) Obtain and document patient demographics, location of primary clinical symptoms, and psychosocial information. (2) Review the symptoms noted in the patient guide. (3) Determine the GSCI classification of the patient’s spine-related complaints. (4) Ask additional questions to determine the GSCI subclassification of the symptom pattern. (5) Consider appropriate treatment interventions. Conclusions The Patient and Clinician Guides are designed to be sufficiently clear to be useful to all patients and clinicians, irrespective of their location, education, professional qualifications, and experience. However, they are comprehensive enough to provide guidance on the management of all spine-related symptoms or disorders, including triage for serious and specific diseases. They are consistent with widely accepted evidence-based clinical practice guidelines. They also allow for adequate documentation and medical record keeping.
These guides should be of value during periods of government-mandated physical or social distancing due to infectious diseases, such as during the COVID-19 pandemic. They should also be of value in underserved communities in high-, middle-, and low-income countries where there is a dearth of accessible trained spine care clinicians. These guides have the potential to reduce the overutilization of unnecessary and expensive interventions while empowering patients to self-manage uncomplicated spinal pain with the assistance of their clinician, either through direct in-person consultation or via telehealth communication.

Abstract
BACKGROUND Spinal disorders are common health problems which include wide categories of diseases that affect the spinal soft tissues, joints and bone. OBJECTIVE The aim of this systematic review was to evaluate the effectiveness of high intensity laser therapy (HILT) on pain and function in patients with spinal disorders. METHODS Six databases were searched up to the end of February 2018 including PubMed, MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), Open Grey and Grey Literature Report. In addition, the reference lists of all included studies were searched for any relevant studies. PEDro scale and GRADE system were performed to assess the quality of the studies. A meta-analysis was conducted to calculate the overall effect size. RESULTS A total of ten randomised controlled trials (RCTs) met the inclusion criteria, with four studies of the efficacy of HILT on neck pain (NP) and six on low back pain (LBP). According to the PEDro scale assessment, only two studies were rated as high quality, while the remainder were rated as fair or low quality. Forest plots showed that HILT with exercise was significantly more effective than placebo HILT with exercise in terms of pain reduction (SMD -1.11; 95% CI -1.42 to -0.80; P< 0.00001; I2 0%) and functional improvement (SMD -1.03; 95% CI -1.33 to -0.72; P< 0.00001; I2 0%). Meta-analyses also showed that HILT alone or HILT with conventional physiotherapy (CPT) significantly provided better outcomes than CPT alone. CONCLUSIONS HILT is considered as a complementary modality for pain reduction and function improvement in patients with spinal disorders. However, the quality of the body of evidence was rated from 'very low' to 'low' quality. Further high quality trials are required for standardisation of irradiation parameters and the treatment protocol to establish the efficacy of HILT for spinal disorders.

Abstract
The ancient and modern literature relevant with the governor vessel disorders is collected systematically and their connotation is reconstructed. After the collection and analysis on the ancient and modern medical books and literature relevant with the governor vessel disorders, it is discovered that the governor vessel disorders in the ancient time are relevant with the running course of the governor vessel, organs and dysfunction. While the governor vessel disorders in modern time are involved with the spine, nerve, respiration, digestion, urinary reproduction, head, face and five sensory organs, etc. No matter in the ancient times or in the modern times, the recognition on the connotation and categorization of the governor vessel are highly similar. In comparison between the governor vessel disorders and the spinal disorders, it is believed that they are possibly the two concepts with the high similarity between the different medical backgrounds of the East and the West.

Abstract
OBJECTIVE Cervical spondylotic myelopathy (CSM) is the most common cause of nontraumatic spinal cord impairment and disability in the world. Given that the Japanese Orthopaedic Association (JOA) score is the most frequently used outcome measure in clinical research and practice for treating patients with CSM, this review was undertaken to comprehensively and critically evaluate the psychometric properties of the JOA score. METHODS The authors identified studies (published in the period of January 1975 to November 2015) on the psychometric properties of the original, revised, and modified versions of the JOA score in Medline, PsycINFO, Excerpta Medica dataBASE (EMBASE), American College of Physicians Journal Club, and Cochrane Database of Systematic Reviews. Additional publications were captured in a secondary search of the bibliographies in both original research articles and literature reviews identified in the original search. The JOA scores were evaluated for item generation and reduction, internal consistency, reliability, validity, and responsiveness. This review included all those versions of the JOA score whose psychometric properties had been reported in at least 2 published studies. RESULTS The primary search strategy identified 59 studies, of which 9 fulfilled the inclusion and exclusion criteria. An additional 18 publications were captured in the secondary search and included in the analysis. The key findings from the 27 studies analyzed indicated the following: 1) the original JOA score (1975) was the source for the revised JOA score (1994) and 3 modified versions (1991, 1993, and 1999 JOA scores) reported or used in at least 2 published studies; 2) the revised and modified versions of the JOA score are markedly different from each other; 3) only the revised JOA score (1994) was validated with the original JOA score; and 4) the 1975 JOA score is the most appropriate instrument for assessing patients in Asian populations (especially from Japan) because of its psychometric attributes, and the 1991 JOA score is the most appropriate version for use in Western populations. CONCLUSIONS The authors' results indicate that the original (1975), revised (1994), and modified (1991, 1993, and 1999) versions of the JOA score are substantially different from each other in terms of their content and have been incompletely examined for their psychometric properties and cultural sensitivity. Whereas the 1975 JOA score is the most appropriate version for assessing individuals from Asian populations (particularly those eating with chopsticks), the 1991 JOA score is most suitable for evaluating patients in Western populations. Nonetheless, further investigation of the psychometric properties of the 1975 and 1991 JOA scores is recommended because of a paucity of studies reporting on the responsiveness of these 2 scoring instruments.

Abstract
Introduction There is consistent evidence to indicate people living in rural and remote regions have limited access to healthcare and poorer health outcomes. One way to address this inequity is through innovative models of care such as telehealth. The aim of this pilot trial was to determine the feasibility, appropriateness and access to a telehealth clinic. In this pilot trial, the telehealth clinic outcomes are compared with the outreach clinic. Both models of care are commonly utilised means of providing healthcare to meet the needs of people living in rural and remote regions. Methods A prospective audit was conducted on a Spinal Assessment Clinic Telehealth pilot trial for patients with spinal disorders requiring non-urgent surgical consultation. Data were recorded from all consultations managed using videoconferencing technology between the Royal Adelaide Hospital and Port Augusta Community Health Service, South Australia between September 2013 and January 2014. Outcomes included analysis of process, service activity, clinical actions, safety and costs. Data were compared to a previous spinal assessment outreach clinic in the same area between August and December 2012. Results There were 25 consultations with 22 patients over the five-month telehealth pilot trial. Spinal disorders were predominantly of the lumbar region (88%); the majority of initial consultations (64%) were discharged to the general practitioner. There were three requests for further imaging, five for minor interventions and three for other specialist/surgical consultation. Patient follow-up post telehealth pilot trial revealed no adverse outcomes. The total cost of AUD$11,187 demonstrated a 23% reduction in favour of the spinal assessment telehealth pilot trial, with the greatest savings in travel costs. Discussion The telehealth model of care demonstrated the efficient management of patients with spinal disorders in rural regions requiring non-urgent surgical consultation at low costs with no adverse outcomes reported.

Abstract
OBJECT Spondyloptosis represents the most severe form of spondylolisthesis, which usually follows high-energy trauma. Few reports exist on this specific condition, and the largest series published to date consists of only 5 patients. In the present study the authors report the clinical observations and outcomes in a cohort of 20 patients admitted to a regional trauma center for severe injuries including spondyloptosis. METHODS The authors performed a retrospective chart review of patients admitted with spondyloptosis at their department over a 5-year period (March 2008-March 2013). Clinical, radiological, and operative details were reviewed for all patients. RESULTS In total, 20 patients with spondyloptosis were treated during the period reviewed. The mean age of the patients was 27 years (range 12-45 years), and 17 patients were male (2 boys and 15 men) and 3 were women. Fall from height (45%) and road traffic accidents (35%) were the most common causes of the spinal injuries. The grading of the American Spinal Injury Association (ASIA) was used to assess the severity of spinal cord injury, which for all patients was ASIA Grade A at the time of admission. In 11 patients (55%), the thoracolumbar junction (T10-L2) was involved in the injury, followed by the dorsal region (T1-9) in 7 patients (35%); 1 patient (5%) had lumbar and 1 patient (5%) sacral spondyloptosis. In 19 patients (95%), spondyloptosis was treated surgically, involving the posterior route in all cases. In 7 patients (37%), corpectomy was performed. None of the patients showed improvement in neurological deficits. The mean follow-up length was 37.5 months (range 3-60 months), and 5 patients died in the follow-up period from complications due to formation of bedsores (decubitus ulcers). CONCLUSIONS To the authors' best knowledge, this study was the largest of its kind on traumatic spondyloptosis. Its results illustrate the challenges of treating patients with this condition. Despite deformity correction of the spine and early mobilization of patients, traumatic spondyloptosis led to high morbidity and mortality rates because the patients lacked access to rehabilitation facilities postoperatively.

Abstract
OBJECT This retrospective study was designed to evaluate the clinical outcomes and radiological findings after open lumbar discectomy (OLD) in patients who were followed up for 10 years or longer. METHODS The authors classified 79 patients who had a mean age (±SD) of 53.6±13.6 years (range 30-78 years) into 4 groups according to the length of their follow-up. Patients in Group 1 were followed up for 10-14 years, in Group 2 for 15-19 years, in Group 3 for 20-24 years, and in Group 4 for more than 25 years. In all of these patients, the clinical outcomes were assessed by using patients' self-reported scores on visual analog scales (VASs) measuring back and leg pain and by using scores from the Oswestry Disability Index (ODI). In addition, 10 radiological parameters suggesting degenerative changes or instability at the operated segment were recorded at various time points and used to calculate a numeric radiological finding (NRF) score by rating a presence for each finding of spinal degeneration or instability as 1. RESULTS The authors observed that OLD decreased pain and disability scores in all groups. Numeric radiological findings were highest in Group 4, and a significant correlation was detected between NRFs and VAS scores of back pain (p=0.039). In this cohort, the reoperation rate was 13.9% during a mean follow-up period of 15.3 years. Clinical outcomes tended to be most favorable in Group 1, representing patients who had OLD most recently, and they tended to deteriorate in the other 3 groups, indicating some worsening of outcomes over time. Degeneration of the spine at the operated level measured with radiographic methods tended to increase over time, but some stabilization was observed. Although spinal degeneration was stable, clinical outcomes deteriorated over time. CONCLUSIONS This cross-sectional assessment of a retrospective cohort indicates that outcomes after OLD deteriorate over time. Increased back pain indicated a worsening of clinical outcomes, and this worsening was correlated with radiological findings of degeneration at the operated segment.

Abstract
OBJECTIVE The purpose of this study was to evaluate whole-body vibration (WBV) exposure to wheelchair (WC) users in their communities and to determine the effect of WC frame type (folding, rigid, and suspension) in reducing WBV transmitted to the person. DESIGN An observational case-control study of the WBV exposure levels among WC users. PARTICIPANTS Thirty-seven WC users, with no pressure sores, 18 years old or older and able to perform independent transfers. MAIN OUTCOME MEASURES WC users were monitored for 2 weeks to collect WBV exposure, as well as activity levels, by using custom vibration and activity data-loggers. Vibration levels were evaluated using ISO 2631-1 methods. RESULTS All WC users who participated in this study were continuously exposed to WBV levels at the seat that were within and above the health caution zone specified by ISO 2631-1 during their day-to-day activities (0.83 ± 0.17 m/second(2), weighted root-mean-squared acceleration, for 13.07 ± 3.85 hours duration of exposure). WCs with suspension did not attenuate vibration transmitted to WC users (V = 0.180, F(8, 56) = 0.692, P = 0.697). Conclusions WBV exposure to WC users exceeds international standards. Suspension systems need to be improved to reduce vibrations transmitted to the users.

Abstract
BACKGROUND CONTEXT Findings on imaging of noncontractile anatomic abnormalities and the intensity of low back pain have weak associations because of false-positive rates among asymptomatic individuals. This association might be stronger for contractile tissues. PURPOSE The purpose of this study was to examine the relationship between location and reports of pain intensity in the low back and exercise-induced muscle damage to the lumbar paraspinal muscles. STUDY DESIGN Nondiagnostic observational study in a laboratory setting. METHODS Delayed onset muscle soreness was induced in the low back of healthy pain-free volunteers. Measures of pain intensity (100-mm visual analog scale [VAS]) and location (area on the pain diagram) were taken before and 48 hours after exercise. Muscle damage was quantified using mechanical pain thresholds, motor performance deficits, and transverse relaxation time (T2)-weighted magnetic resonance imaging (MRI). Changes pre- to postexercise in signal intensity on T2-weighted imaging within the erector spinae, pain intensity, pain area, mechanical pain threshold, and isometric torque were assessed using paired t tests. Bivariate correlations were conducted to assess associations among muscle damage, pain intensity, and pain drawing area. RESULTS Twenty participants volunteered (11 women; average age, 22.3 years; average body mass index, 23.5) for study participation. Reports of pain intensity at 48 hours ranged from 0 to 59 mm on the VAS. Muscle damage was confirmed by reductions in mechanical threshold (p=.011) and motor performance (p<.001) and by changes in T2-weighted MRI (p=.007). This study was powered to find an association of at least r=0.5 to be statistically significant. Correlations of continuous variables revealed no significant correlations between pain intensity and measures of muscle damage (ranging between -0.075 and 0.151). There was a significant association between the remaining torque deficit at 48 hours and pain area. CONCLUSIONS The results of this study indicate that there was no association between the magnitude of muscle damage in the lumbar erector spinae and reported pain intensity in the low back. In future studies, larger cohorts may report statistically significant associations, but our data suggest that there will be low magnitude potentially indicating limited clinical relevance.
