Lumbopelvic Muscle Mobility and Resistance and their Association with Musculoskeletal Pain in Ballet Dancers / Mobilidade e resistência muscular lombopélvica e associação com dor musculoesquelética em bailarinas

Abstract Objective The present study analyzes ankle mobility and lumbopelvic muscle mobility and resistance. In addition, it identifies factors associated with musculoskele-tal pain in young ballet dancers. Methods This is a quantitative, descriptive, cross-sectional study evaluating 14 ballet dancers aged 12 to 16 years old. We used the following instruments: a) Nordic Musculoskeletal Symptom Questionnaire (NSQ) for musculoskeletal pain assessment; b) leg lateral reach test, lumbar lock, and rotation test (for trunk mobility analysis) and lunge test (for ankle mobility evaluation); c) front bridge, lumbar extensor, and lumbar flexor muscles tests to assess lumbopelvic complex resistance. Results The main complaints reported by ballet dancers were pain in the low back area and in the lower extremities, especially in the knee (57.1%). Those with low back pain had significantly lower lumbar mobility ( p = 0.05) and lower ankle mobility on both sides ( p ≤ 0.05). Dancers with knee pain presented significantly lower muscular trunk extensor muscle resistance ( p = 0.05). Conclusions Our study revealed significant associations between the lumbopelvic complex function and musculoskeletal symptoms, supporting the implementation of preventive strategies.

Lumbar Facet Syndrome and the Use of Radiofrequency Ablation Technique as an Alternative Therapy: A Systematic Review / Síndrome facetária lombar e a utilização da técnica de ablação por radiofrequência como terapia alternativa: uma revisão sistemática

Abstract Lumbar facet syndrome stands out as a significant cause for the increasing prevalence of back pain complaints. Alternatives such as radiofrequency (RF) ablation may be a therapeutic option to relieve the chronic pain associated with this condition. It is critical to analyze the effectiveness of lumbar facet syndrome treatment using the traditional RF ablation technique and the relief generated by it in chronic low back pain (CLBP). This study is a systematic review using the following inclusion criteria: title, observational studies, clinical trials, controlled clinical trials, clinical studies, and publications over the last 17 years (from 2005 to 2022). The exclusion criteria included papers addressing other themes and review articles. The databases used for data collection included the Medical Literature Analysis and Retrieval System Online (Medline), PubMed, Scientific Electronic Library Online (SciELO), Lilacs, and Biblioteca Virtual em Saúde (Virtual Health Library in Portuguese). The query used the following terms: facet, pain, lumbar, and radiofrequency. The application of these filters yielded 142 studies, and 12 were included in this review. Most studies indicated that the traditional RF ablation technique was beneficial in relieving CLBP refractory to conservative treatment.

Sitmate: an android mobile application for the prevention of musculoskeletal discomfort among a business process outsourcing company workforce management personnel / The Health Sciences Journal

INTRODUCTION@#Due to COVID-19 pandemic, many have shifted into working at home which led to physical inactivity. This may cause musculoskeletal discomfort, chronic disease, muscle atrophy and spinal imbalance due to improper and prolonged sitting posture. Since mobile devices are relatively available for most of the office workers, there were still a lack of evidence-based mobile applications that can counteract the inactivity through exercises, which led to the researchers to create an application called SitMate that consists of evidence-based exercises which aimed to prevent musculoskeletal discomfort among a business process outsourcing company Workforce Management Personnel (BPO-WMP).@*METHODS@#Eleven participants (18-40 years old) full-time, work-from-home BPO-WMP were randomized into Treatment Group(TG)(n=6) and Control Group (CG)(n=5). The TG received one month intervention with the use of SitMate Application containing relaxation exercises, range of motion exercises and stretching exercises, and notifications for postural correction while the CG continued their usual working schedule.@*RESULTS@#There were no significant differences between two groups on all body parts that were measured using the Cornell Musculoskeletal Discomfort Questionnaire, and no significant differences in the intragroup pre-test and post-test scores on all body parts between TG and CG. For the intra-group post-test of the TG, there were noted improvements on the hip/buttock, right shoulder, upper back (median = 0) and right wrist (median = 1.5). There was also a noted increase in discomfort on the neck (median = 1.5) and lower back (median = 3). For the post-test of the CG, there were noted improvements on the right shoulder, right wrist (median = 0) and lower back (median = 1.5).@*CONCLUSION@#This study has shown that the SitMate application does not effectively reduce the prolonged sitting-related discomfort among the personnel after 1 month of intervention.

Laser acupuncture combined with auricular acupressure improves low-back pain and quality of life in nurses: A randomized controlled trial / 中西医结合学报

BACKGROUND@#Low-back pain (LBP) in nurses is a major health concern that affects their quality of life and ability to work, with consequences for their economic status.@*OBJECTIVE@#This study evaluates the effect of low-level laser acupuncture combined with auricular acupressure (LAA) on pain intensity, pain interference and quality of life in nurses with LBP.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS@#This randomized controlled trial recruited a convenience sample of hospital-based nurses from one teaching hospital in Taiwan, China. Participants were randomly assigned to the LAA group (n = 38) receiving low-level laser acupuncture and auricular acupressure for 4 weeks, and the control group (n = 38) receiving only sham laser acupuncture treatment without laser energy output.@*MAIN OUTCOME MEASURES@#Data were collected for the primary pain outcome using the Short Form of the Brief Pain Inventory, while the secondary outcome, quality of life, was evaluated using the Roland-Morris Disability Questionnaire. Both primary and secondary outcomes were scored before the intervention, and after 2-week and 4-week intervention. The rate of LBP recurrence was evaluated at the 4th week and 8th week after the end of intervention.@*RESULTS@#After controlling for prior pain, the result of linear mixed model analysis showed trends in significant between-group differences in the level of current pain occurring in week 4 (P < 0.001), worst pain in week 2 (P < 0.001) and week 4 (P < 0.001), least pain in week 2 (P = 0.032) and week 4 (P < 0.001), pain interference in week 2 (P = 0.009) and week 4 (P < 0.001), and in the life dysfunction in week 2 (P < 0.001) and week 4 (P < 0.001). Recurrence rates of LBP at the 4th and 8th weeks after the end of intervention were 0% and 36.89% in the LAA group, and 69.44% and 36.11% in the control group.@*CONCLUSION@#This study shows that 4-week LAA intervention reduced pain intensity and pain interference, and improved quality of life for hospital-based nurses with LBP. These effects were maintained continuously for at least 4 weeks after the intervention. The nonpharmacological intervention, LAA, may be another efficacious, feasible, noninvasive, analgesic intervention for LBP.@*TRIAL REGISTRATION@#This study is registered at Clinicaltrials.gov (registration number NCT04423445).

Systematic review and Meta-analysis of Gusongbao preparation in treatment of primary osteoporosis / 中国中药杂志

This study aims to provide evidence for clinical practice by systematically reviewing the efficacy and safety of Gusongbao preparation in the treatment of primary osteoporosis(POP). The relevant papers were retrieved from four Chinese academic journal databases and four English academic journal databases(from inception to May 31, 2022). The randomized controlled trial(RCT) of Gusongbao preparation in the treatment of POP was included after screening according to the inclusion and exclusion criteria. The quality of articles was evaluated using risk assessment tools, and the extracted data were subjected to Meta-analysis in RevMan 5.3. A total of 657 articles were retrieved, in which 15 articles were included in this study, which involved 16 RCTs. A total of 3 292 patients(1 071 in the observation group and 2 221 in the control group) were included in this study. In the treatment of POP, Gusongbao preparation+conventional treatment was superior to conventional treatment alone in terms of increasing lumbar spine(L2-L4) bone mineral density(MD=0.03, 95%CI[0.02, 0.04], P<0.000 01) and femoral neck bone mineral density, reducing low back pain(MD=-1.69, 95%CI[-2.46,-0.92], P<0.000 1) and improving clinical efficacy(RR=1.36, 95%CI[1.21, 1.53], P<0.000 01). Gusongbao preparation was comparable to similar Chinese patent medicines in terms of improving clinical efficacy(RR=0.95, 95%CI[0.86, 1.04], P=0.23). Gusongbao preparation was inferior to similar Chinese patent medicines in reducing traditional Chinese medicine syndrome scores(MD=1.08, 95%CI[0.44, 1.71], P=0.000 9) and improving Chinese medicine syndrome efficacy(RR=0.89, 95%CI[0.83, 0.95], P=0.000 4). The incidence of adverse reactions of Gusongbao preparation alone or combined with conventio-nal treatment was comparable to that of similar Chinese patent medicines(RR=0.98, 95%CI[0.57, 1.69], P=0.94) or conventio-nal treatment(RR=0.73, 95%CI[0.38, 1.42], P=0.35), and the adverse reactions were mainly gastrointestinal discomforts. According to the available data, Gusongbao preparation combined with conventional treatment is more effective than conventional treatment alone in increasing lumbar spine(L2-L4) bone mineral density and femoral neck bone mineral density, reducing low back pain, and improving clinical efficacy. The adverse reactions of Gusongbao preparation were mainly gastrointestinal discomforts, which were mild.

Treatment of stable degenerative lumbar spondylolisthesis with percutaneous endoscopic surgery through two different approaches / 中国骨伤

OBJECTIVE@#To assess the clinical effects of percutaneous endoscopic surgery through two different approaches for stable degenerative lumbar spondylolisthesis.@*METHODS@#Sixty-four patients with stable degenerative lumbar spondylolisthesis who underwent percutaneous endoscopic procedures between January 2016 and December 2019 were divided into transforaminal approach group and interlaminar approach group according to surgical approaches, 32 patients in each group. There were 16 males and 16 females in transforaminal approach group, aged from 52 to 84 years old with an average of (66.03±9.60) years, L2 slippage in 4 cases, L3 slippage in 5, and L4 slippage in 23. There were 17 males and 15 females in interlaminar approach group, aged from 46 to 81 years old with an average of (61.38±9.88) years, L3 slippage in 3 cases, L4 slippage in 15, and L5 slippage in 14. Operative time, intraoperative fluoroscopy times, and postoperative bedtime were compared between two groups. Anteroposterior displacement values, interbody opening angles, and the percentage of slippage were measured on preoperative and postoperative 12-month dynamic radiographs. Visual analogue scale (VAS) of low back pain and lower extremity pain, and the Japanese Orthopaedic Association (JOA) score before and after surgery were observed, and clinical effects were evaluated according to the modified MACNAB criteria.@*RESULTS@#All operations were successfully completed, and patients in both groups were followed up for more than 1 year, and without complications during follow-up period. ①There was no significant difference in operation time between two groups(P>0.05). Intraoperative fluoroscopy times were longer in transforaminal approach group than that in intervertebral approach group(P<0.05). Postoperative bedtime was shorter in transforaminal approach group than that in intervertebral approach group (P<0.05).② No lumbar instability was found on dynamic radiography at 12 months postoperatively in both groups. There were no significant differences in anteroposterior displacement values, interbody opening angles, and the percentage of slippage between two groups postoperative 12 months and preoperative 1 day(P>0.05). ③There was no significant difference between two groups in VAS of low back pain at 3 days and 1, 12 months after the operation compared with the preoperative(P>0.05), but the VAS of the lower extremity pain was significantly improved compared with the preoperative(P<0.05). Both of groups showed significant improvement in JOA score at 12 months compared with preoperatively(P<0.05). There was no significant difference in VAS of low back pain, lower extremity pain and JOA scores between two groups during the same period after surgery(P>0.05). According to modified Macnab criteria, excellent, good, fair and poor outcomes were 21, 7, 3 and 1 in transforaminal approach group respectively, and which in intervertebral approach group were 20, 7, 5 and 0, there was no significant difference in clinical effect between the groups(P>0.05).@*CONCLUSION@#Intervertebral approach may reduce intraoperative fluoroscopy times and transforaminal approach can shorten postoperative bedtime, both approaches achieve satisfactory results in the treatment of stable degenerative lumbar spondylolisthesis with no progression of short-term slippage.

Pathogenesis and staging treatment for non-specific low back pain based on the meridian sinew theory / 中国针灸

Based on the physiological and pathological characteristics of meridian sinew theory, the staging treatment of non-specific low back pain (NLBP) is explored to provide the reference of clinical practice. The twelve meridian sinews of the human body communicate with the bones and joints of the whole body, which governs the movement, body protection and defense, and meridian regulation. Physiologically, the meridian sinew maintains the functions of the lumbar region. In pathology, the meridian sinew may encounter stasis and pain, contraction and spasm or "transverse collateral" formation. According to the pathological staging of meridian sinew disorders, the progress of NLBP is divided into 3 phases and the corresponding treatments are provided. Mild stimulation and rapid analgesia is suggested to promote tissue repair at the early phase; muscle spasm is relieved to adjust muscular status at the middle phase; and the "cord-like" muscle foci is removed at the later phase of the disease.

Early-effectiveness of unilateral biportal endoscopic laminectomy in treatment of two-level lumbar spinal stenosis / 中国修复重建外科杂志

OBJECTIVE@#To analyze the early effectiveness of unilateral biportal endoscopy (UBE) laminectomy in the treatment of two-level lumbar spinal stenosis (LSS).@*METHODS@#The clinical data of 98 patients with two-level LSS treated with UBE between September 2020 and December 2021 were retrospectively analyzed. There were 53 males and 45 females with an average age of 59.9 years (range, 32-79 years). Among them, there were 56 cases of mixed spinal stenosis, 23 cases of central spinal canal stenosis, and 19 cases of nerve root canal stenosis. The duration of symptoms was 1.5- 10 years, with an average of 5.4 years. The operative segments were L 2, 3 and L 3, 4 in 2 cases, L 3, 4 and L 4, 5 in 29 cases, L 4, 5 and L 5, S 1 in 67 cases. All patients had different degrees of low back pain, among of which 76 cases were with unilateral lower extremity symptoms and 22 cases were with bilateral lower extremity symptoms. There were 29 cases of bilateral decompression in both segments, 63 cases of unilateral decompression in both segments, and 6 cases of unilateral decompression and bilateral decompression of each segment. The operation time, intraoperative blood loss, total incision length, hospitalization stay, ambulation time, and related complications were recorded. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months after operation, and at last follow-up. The Oswestry disability index (ODI) was used to evaluate the functional recovery of lumbar spine before operation and at 3 months and last follow-up after operation. Modified MacNab criteria was used to evaluate clinical outcomes at last follow-up. Imaging examinations were performed before and after operation to measure the preservation rate of articular process, modified Pfirrmann scale, disc height (DH), lumbar lordosis angle (LLA), and cross-sectional area of the canal (CAC), and the CAC improvement rate was calculated.@*RESULTS@#All patients underwent surgery successfully. The operation time was (106.7±25.1) minutes, the intraoperative blood loss was (67.7±14.2) mL, and the total incision length was (3.2±0.4) cm. The hospitalization stay was 8 (7, 9) days, and the ambulation time was 3 (3, 4) days. All the wounds healed by first intention. Dural tear occurred in 1 case during operation, and mild headache occurred in 1 case after operation. All patients were followed up 13-28 months with an average of 19.3 months, and there was no recurrence or reoperation during the follow-up. At last follow-up, the preservation rate of articular process was 84.7%±7.3%. The modified Pfirrmann scale and DH were significantly different from those before operation ( P<0.05), while the LLA was not significantly different from that before operation ( P=0.050). The CAC significantly improved ( P<0.05), and the CAC improvement rate was 108.1%±17.8%. The VAS scores of low back pain and leg pain and ODI at each time point after operation significantly improved when compared with those before operation, and the differences between each time points were significant ( P<0.05). According to the modified MacNab criteria, 63 cases were excellent, 25 cases were good, and 10 cases were fair, with an excellent and good rate of 89.8%.@*CONCLUSION@#UBE laminectomy is a safe and effective technique with little trauma and fast recovery for two-level LSS and the early effectiveness is satisfactory.

Introduction: Degenerative lumbar spine disease is prevalent, however, the criteria for instability are still debated. Objectives:To analyze the presence of the lumbar facet fluid sign as a criterion for segmental instability of the spine. materials and meth-ods: Patients with chronic lumbar disease, who present facet hydrarthrosis on MRI and dynamic lumbar spine radiographs. The prevalence of sex, age, main symptomatology, and pain on unilateral or bilateral extension was investigated. Results: A total of 139 patients (62% women) were evaluated, with an average age of 50.8 years; the main reason for consultation was low back pain (76%). Sixty-five percent reported pain in extension, with 35% reporting unilateral pain and 30% reporting bilateral pain. Fourteen percent had low-grade spondylolisthesis at L4-L5 and 7% at L5-S1. Hydrarthrosis was unilateral in 20% and bilateral in 80%; the most frequent level of hydrarthrosis was L4-L5 (58%). Six percent had only translational instability and 2% had mixed instability. 8% and 5%, respectively, had Modic I and Modic II changes. Conclusions: The presence of facet fluid is not a criterion for segmental instability of the spine, regardless of the level and localized segment, or the unilateral or bilateral lumbar facet presentation.

Efectividad de la fisioterapia para el dolor de espalda baja apoyada en recursos digitales / Effectiveness of physiotherapy for low back pain supported by digital resources

El número de intervenciones terapéuticas apoyadas en el uso de los recursos digitales aumenta cada día como vía para facilitar el acceso a cualquier tipo de atención sanitaria. Se realizó una revisión sistemática con el objetivo de analizar la efectividad (estado funcional, la intensidad del dolor y la adherencia al tratamiento) de la intervención de fisioterapia, apoyada en recursos digitales, frente a la fisioterapia convencional en pacientes adultos con dolor de espalda. Este estudio consultó las bases de datos científicas: PubMed, Biblioteca Virtual en Salud, Cochrane, Base de datos de Fisioterapia basada en la evidencia, Science Direct, Scopus, Episteminikos y Google Académico. La selección inicial de los estudios, la evaluación exhaustiva de los artículos completos y la extracción de las características necesarias para la investigación fueron realizadas por los seis investigadores y revisadas por dos revisores independientes. Se incluyeron 12 artículos (10 ensayos clínicos y dos estudios de cohorte). Los resultados de la revisión sistemática soportan el uso de los recursos digitales disponibles para el manejo de dolor de espalda baja, con una importante relación con la reducción de los niveles de dolor y la mejora en la funcionalidad. Es necesario realizar más estudios de alta calidad para evidenciar estos resultados, pues están por determinarse los criterios de la intervención(AU)

The number of therapeutic interventions supported by the use of digital resources is increasing every day as a way to facilitate access to any type of health care. A systematic review was carried out with the aim of analyzing the effectiveness (functional status, pain intensity and adherence to treatment) of the physiotherapy intervention, supported by digital resources, compared to conventional physiotherapy in adult patients with back pain. This study consulted the scientific databases such as PubMed, Virtual Health Library, Cochrane, Evidence-Based Physiotherapy Database, Science Direct, Scopus, Episteminikos, and Google Scholar. The initial selection of the studies, the exhaustive evaluation of the full articles and the extraction of the characteristics necessary for the investigation were carried out by the six research fellows and reviewed by two independent reviewers. Twelve articles were included (10 clinical trials and two cohort studies). The results of the systematic review support the use of available digital resources for the management of low back pain, with an important relationship with the reduction of pain levels and the improvement in functionality. It is necessary to carry out more high-quality studies to demonstrate these results, since the criteria for the intervention are yet to be determined(AU)

Facet Tropism/Inclination and Its Association with Intervertebral Disc Herniation in the Lumbar Spine - A Radiological Evaluation / Tropismo/inclinação facetária e sua associação com hérnia de disco intervertebral na região lombar da coluna - Uma avaliação radiológica

Abstract Objective To assess the role of facet tropism (FT) in intervertebral disc prolapse. Methods A total 98 patients with lower back pain were included in the study. Magnetic resonance imaging scans were performed and analyzed. The angles of the right and left facets were measured on the axial section. Patients without disc prolapse at the L3-L4, L4-L5 and L5-S1 levels act as controls for those with disc prolapse at the same levels. A statistical analysis was also performed. Results The incidence of FT at the L3-L4 level was of 85.2% in patients with disc herniation (n= 27), and of 56.3% in the control group, which was statistically significant (p= 0.008). Similarly, at the L4-L5 level, incidence of FT among cases and controls was of 71.4% (n= 35) and 52.4% respectively (p= 0.066). At the L5-S1 the incidence was of 66% and 51% among cases and controls respectively (p= 0.13). Conclusion We found a positive association between FT and disc herniation at the L3-L4 level, but no association at the L4-L5 and L5-S1 levels.

Abstract Objectives To verify if there is a difference in postural hypervigilance in sitting in individuals with and without low back pain. Additionally, to observe whether there is a difference in the perception of correct sitting posture between individuals with low back pain and without low back pain. Methods The present study has a cross-sectional observational design, as a sample size of 92 individuals, later divided equally into two groups (with low back pain and without low back pain). Two instruments were used: the hypervigilance scale to analyze the frequency that volunteers correct their sitting posture during the day, and posture scans to investigate the perception of volunteers about the correct sitting posture. The data were submitted to the Shapiro-Wilk Normality test. To compare the values of Hypervigilance Scale, the Mann-Whitney, Chi-Square, and Fisher Exact tests were used to assess correct sitting posture. Results There was no significant difference between postural hypervigilance in sitting between individuals with low back pain and without low back pain. There was no significant difference between the choice of correct sitting posture between the group of individuals with and without low back pain. Conclusion There is no difference between the choice of correct sitting posture and the amount of postural hypervigilance in individuals with or without low back pain.
