RESUMO

BACKGROUND: Altered lower back muscle activity is proposed as a contributing factor to the reoccurrence and chronicity of low back pain (LBP). This study compared lumbar muscle activity during trunk extension in patients with continuous chronic LBP (CLBP), non-continuous CLBP, recurrent LBP (RLBP) and healthy subjects. METHODS: In 75 subjects (16 continuous CLBP, 15 non-continuous CLBP, 23 RLBP, 21 healthy controls), surface electromyographic (EMG) activity of the lumbar erector spinae (ES), multifidus (MF), latissimus dorsi (LD) and gluteus maximus (GM) was recorded during the concentric, holding and eccentric phase of a modified Biering Sorenson exercise. RESULTS: Continuous CLBP patients showed higher EMG activity in the ES and MF muscles compared to healthy controls in the concentric (p = 0.011; p = 0.009 respectively) and the holding phase (p = 0.015; p = 0.013). Higher EMG activity was observed in continuous CLBP compared to RLBP in the ES and MF muscles in the holding phase (p = 0.035; p = 0.037), and in the MF in the concentric phase (p = 0.046), but not in the ES (p = 0.062). No differences in muscle activity were established in either the concentric, holding, and eccentric phase for the LD and GM muscles. No differences were found between non-continuous CLBP and the other groups. CONCLUSIONS: An enhanced muscle activity of the lumbar muscles during the concentric and holding phase was observed during trunk extension in patients with continuous CLBP compared to patients with RLBP and healthy subjects. No differences between groups are present in the GM and LD muscles during concentric and holding phases and for any muscle in the eccentric phase.

RESUMO

BACKGROUND: The Japanese Orthopaedic Association (JOA) proposed the concept of locomotive syndrome (LS) in 2007 for detecting high-risk individuals with mobility limitation. In 2020, the JOA revised the clinical decision limits and introduced LS stage 3, which carried the highest-risk for LS compared to the conventional stages, 1 and 2. The purpose of this study was to characterize the prevalence, comorbidities, and physical characteristics in each LS stage, as per the LS criteria 2020. METHODS: We analyzed 2077 participants (64.9% women; mean age, 68.3 ± 5.4 years) from the Nagahama Study aged ≥60 years. Participants were classified into 4 groups, non-LS and LS stages 1, 2, and 3, based on a 25-question Geriatric Locomotive Function Scale. The prevalence of comorbidities (sarcopenia, osteoporosis, diabetes mellitus, low back pain [LBP], and knee pain) were investigated. Physical characteristics were measured based on the physical performance tests including gait speed, five-times chair-stand, single-leg stand, and short physical performance battery; muscle strength tests including grip, knee extension, hip flexion, and abduction; and body-composition analysis including muscle quantity and quality. Differences in the prevalence of comorbidities between LS stages were tested using the chi-square test. The general linear model was performed for univariate and multivariate analyses with post-hoc test to compare the differences in physical characteristics among the LS stages. RESULTS: The prevalence of LS increased with age, and the mean prevalence of LS stages 1, 2, and 3 were 24.4, 5.5, and 6.5%, respectively. The prevalence of comorbidities, including sarcopenia, osteoporosis, LBP, and knee pain, increased with worsening LS stage. Physical performance tests were significantly different between LS stages 2 and 3; and muscle strength differed significantly between LS stages 1 and 2. Additionally, in terms of body composition analysis, muscle quality but not muscle quantity showed significant differences among all the LS stages. CONCLUSIONS: Our findings suggest that muscle strengthening and dynamic training, including balance training in LS stage 1 and 2, respectively, were needed for preventing the LS progression. Individuals with LS stage 3 should perform dynamic training and muscle strengthening exercises while receiving treatment for comorbidities.

RESUMO

STUDY DESIGN: Retrospective. OBJECTIVE: The aim of this study was to investigate the effect of body mass index (BMI) on pain and disability in patients with chronic mechanical low back pain (LBP) treated with multimodal rehabilitation. SUMMARY OF BACKGROUND DATA: Despite being a well-known risk factor for developing LBP, there is minimal data on the effect of BMI on pain and disability in patients with chronic mechanical low back pain (LBP) treated with multimodal rehabilitation. METHODS: Data from patients with chronic mechanical LBP who underwent multimodal rehabilitation treatment at a chain of spine rehabilitation outpatient clinics in one of the three BMI groups-1564 patients in normal body weight (BMI ≥18.5-24.9), 1990 patients in overweight (BMI ≥25-29.9), and 891 patients in obese (BMI ≥ 30) groups-were retrospectively analyzed. Pre- and post-treatment Numerical Pain Rating Scale (NPRS) and Oswestry Disability Index (ODI) scores, and final treatment outcomes were compared between the three groups. Multivariate analysis was used to determine the association between pre-treatment covariates and post-treatment clinical outcomes. RESULTS: Post-treatment, the mean NPRS (P = 0.005) and mean ODI (P < 0.001) scores were significantly higher with a significantly lower percentage of full success outcome (P = 0.009) in the obese group when compared to normal and overweight groups. However, multivariate analysis showed a significant correlation between age, the number of treatment sessions, pre-treatment NPRS and ODI scores, and post-treatment NPRS and ODI scores and treatment failure, and no correlation with patient BMI. CONCLUSION: Patient BMI may not affect pain and disability outcomes in patients undergoing a multimodal rehabilitation treatment for chronic LBP. In contrast to BMI, other covariates such as age, treatment sessions, and pre-treatment NPRS and ODI scores may be associated with increased risk for poor treatment outcome. Obese individuals can expect clinical outcomes similar to normal or overweight individuals with multimodal physical rehabilitation for chronic LBP.Level of Evidence: 3.

RESUMO

STUDY DESIGN: RAND/UCLA Appropriateness Method (RUAM) applied to chiropractic manipulation for patients with chronic low-back pain (CLBP) and chronic neck pain (CNP). OBJECTIVE: Determine the rate of appropriate care provided by US chiropractors. SUMMARY OF BACKGROUND DATA: Spinal manipulation has been shown effective for CLBP and CNP but may not be appropriate for all patients with these conditions. METHODS: Ratings of the appropriateness of spinal and cervical manipulation previously developed by two RUAM expert panels were applied to data abstracted from random samples of patient charts from chiropractors in six US regions to determine the appropriateness of manipulation for each patient. RESULTS: Of 125 chiropractors sampled, 89 provided charts that could be abstracted. Of the 2128 charts received, 1054 were abstracted. Charts received but not abstracted included 460 that were unusable (e.g., illegible), and 555 did not have CLBP or CNP. Across the abstracted charts 72% had CLBP, 57% had CNP, and 29% had both; 84% of patients with CLBP and 86% with CNP received manipulation. Patients with CLBP who had minor neurologic findings, sciatic nerve irritation, or no joint dysfunction were significantly less likely to receive manipulation. Patients with CNP who had substantial trauma etiology, no joint dysfunction, or no radiographs were significantly less likely to receive manipulation. Most manipulation for CLBP (64%) was appropriate and most manipulation for CNP (93%) was for patients where appropriateness was uncertain or equivocal. The proportions of patients receiving inappropriate manipulation for either condition were low (1%-3%) as were the numbers of patients presenting to these chiropractors for which manipulation was inappropriate. CONCLUSION: Chiropractors in this US sample tend to provide manipulation to very few patients with CLBP or CNP for which it is inappropriate. However, more research is needed to determine which patients with CNP benefit from manipulation.Level of Evidence: 4.

RESUMO

The purpose of this review is to provide an overview of current literature on the diagnosis and treatment of sacroiliac pain. Designation as a source of lower back pain has been controversial; However, as knowledge about the joint increases, its role as a generator of chronic pain has become better elucidated. The literature states that sacroiliac joint is the cause of pain in up to 30% of patients. Clinically, diagnosing sacroiliac pain can be difficult to assess; However, pain semiology, patient posture/movement and manual testing are useful for making the presumptive diagnosis of sacroiliac dysfunction. The most effective diagnostic test is image-guided injection of anesthetic solutions into the joint, which is considered positive if there is at least 75% acute symptom relief. Treatment begins with physiotherapy and/or intra-articular infiltration of steroids. If these fails, a possible option is radiofrequency (rizotomy) denervation of the joint. If this does not provide adequate relief, surgery may be considered, in the form of fusion; various work supports favorable outcomes in selected patients.

RESUMO

Chronic low back pain and biomechanical walking imbalances are closely related. It is relevant to identify if there are alterations in spatiotemporal gait patterns in subjects with CLBP (cases) versus healthy subjects (controls) to plan training interventions of motor control gait patterns, and thus allowing normal physical activity of the individual. This study is intended to identify if spatiotemporal alterations occur in the gait cycle in CLBP subjects (cases) compared with a control group (healthy patients) analyzed with an OptoGait LED sensors gait program. METHOD: A total of n = 147 participants: n = 75 cases (CLBP) and n = 72 healthy controls subjects were studied with OptoGait gait program. RESULTS: Significant differences were found between the two groups and both feet in foot stride, for the differences of the total stride and contact, for gait cadence and total stride length of the gait cycle (p < 0.05). CONCLUSIONS: CLBP may alter some normal gait patterns measured by OptoGait; this finding presents imbalances in gait cycle as an underlying factor. The gait is part of daily life of any individual and it is an important physical activity in relation to the maintenance of an optimal state of health. In addition, future studies are deemed necessary.

RESUMO

BACKGROUND: Chronic back pain is known to be associated with altered tactile acuity. Tactile acuity is measured using the Two-Point Discrimination (TPD) test in both clinical and research settings. In subjects with chronic low back pain, the TPD threshold (TPDT) is increased and is associated with persistent pain. It remains unknown, however, whether TPDT is also altered in cases of clinical acute pain, or whether it could be used as a predictor of future pain and disability at an early stage of LBP. The main objective of this study was to investigate the predictive value of baseline TPDT for pain and disability at 3 and 6 months after the onset of acute LBP. The TPDT in acute low back pain (LBP) and the development of TPDT over 6 months has also been assessed. METHODS: LBP participants (n = 124) with acute LBP (< 4 weeks) were included. Subjects were examined within 4 weeks of pain onset and followed-up after 3 and 6 months of pain onset. Horizontal and vertical TPDTs of the lower back were collected. Linear mixed models were subsequently used to evaluate the association of TPDT with pain and disability over time. RESULTS: The vertical TPDT showed a mean (SD) of 4.9 cm (1.6) and the horizontal TPDT a mean (SD) of 6.0 cm (1.5) at baseline. The vertical TPDT altered from baseline up to 6 months from 4.9 to 4.6 cm and the horizontal TPDT from 6.0 to 5.4 cm. The association between the TPDT and the Oswestry Disability Index (ODI) after 6 months was moderate. Linear mixed models revealed no association between TPDT, pain and disability over the progression of LBP. CONCLUSION: TPDTs appear to be raised in subjects with acute LBP. However, our study revealed no predictive capability of the TPDT for disability and pain. No comparisons are possible in the absence of similar studies, indicating the need for further research is in this area.

RESUMO

BACKGROUND: The active hip abduction test (AHAbd) is widely used to evaluate lumbopelvic stability, but the onset of trunk muscle activation during the test in individuals with recurrent low back pain (rLBP) has not been investigated so far. It is important to investigate the pattern of trunk muscle activation during the AHAbd test to provide insight into the interpretation of observation-based assessment results; this may help to create exercise therapy interventions, from a movement control perspective, for people seeking treatment for rLBP. The purpose of this study was to compare the timing of trunk muscle activation between individuals with and without rLBP and to assess potential differences. METHODS: Seventeen subjects in remission from rLBP and 17 subjects without rLBP were recruited. We performed surface electromyography of the transversus abdominis/internal abdominal oblique, external oblique, erector spinae, and gluteus medius muscles during the AHAbd test on both sides. The onset of trunk muscle activation was calculated relative to the prime mover gluteus medius. The independent-samples t- and Mann-Whitney U tests were used to compare the onset of trunk muscle activation between the two groups. RESULTS: The onset of transversus abdominis/internal abdominal oblique activation on the ipsilateral (right AHAbd: -3.0 ± 16.2 vs. 36.3 ± 20.0 msec, left AHAbd: -7.2 ± 18.6 vs. 29.6 ± 44.3 ms) and contralateral sides (right AHAbd: -11.5 ± 13.9 vs. 24.4 ± 32.3 ms, left AHAbd: -10.1 ± 12.5 vs. 23.3 ± 17.2 ms) and erector spinae on the contralateral side (right AHAbd: 76.1 ± 84.9 vs. 183.9 ± 114.6 ms, left AHAbd: 60.7 ± 70.5 vs. 133.9 ± 98.6 ms) occurred significantly later in individuals with rLBP than in individuals without rLBP (p < 0.01). During the left AHAbd test, the ipsilateral erector spinae was also activated significantly later in individuals with rLBP than in individuals without rLBP (71.1 ± 80.1 vs. 163.8 ± 120.1 ms, p < 0.05). No significant difference was observed in the onset of the external oblique activation on the right and left AHAbd tests (p > 0.05). CONCLUSIONS: Our results suggest that individuals with rLBP possess a trunk muscle activation pattern that is different from that of individuals without rLBP. These findings provide an insight into the underlying muscle activation patterns during the AHAbd test for people with rLBP and may support aggressive early intervention for neuromuscular control.

RESUMO

INTRODUCTION: Low back pain (LBP) is widely prevalent in healthcare workers. It is associated with impaired postural and core stability. So far, centre of pressure (CoP) measures have been commonly recorded through the use of a force plate in order to assess postural stability. However, this approach provides limited information about the centre of mass (CoM) movement in the lumbar region in individuals with LBP. Recent developments in sensor technology enable measurement of the trunk motion which could provide additional information on postural sway. However, the question remains as to whether CoM measures would be more sensitive in discriminating individuals with mild and moderate back pain than traditional CoP analyses. This study aims to investigate the sensitivity of CoP and CoM measures under varied stable, metastable and unstable testing conditions in healthcare workers, and their relationship with the level of subjective reported back pain. METHODS AND ANALYSIS: This is a cross-sectional controlled laboratory study. A group of 90 healthcare professionals will be recruited from rehabilitation centres within local areas. Participants will complete the Oswestry Disability Questionnaire. The primary outcome will be the rate of their back pain on the 0-10 Low Back Pain Scale (1-3 mild pain and 4-6 moderate pain). Secondary outcomes will include variables of postural and core stability testing during bipedal and one-legged stance on a force plate, a foam mat placed on the force plate, and a spring-supported platform with either eyes open or eyes closed. Both CoP using the posturography system based on a force plate and CoM using the inertial sensor system placed on the trunk will be simultaneously measured. ETHICS AND DISSEMINATION: Projects were approved by the ethics committee of the Faculty of Physical Education and Sport, Comenius University in Bratislava (Nos. 4/2017, 1/2020). Findings will be published in peer-reviewed journals and presented at conferences.

RESUMO

BACKGROUND: The BackAche Disability Index (BADIX) is a 2-section test: (a) the BackAche Index encompassing 5 active back movements, evaluated on a 4-point Likert-type rating scale; (b) the morning Back Stiffness Score, choosing the most fitting statement out of 6, upon awakening. OBJECTIVE: To perform a cross-cultural adaptation and evaluate the reliability and validity of the Hebrew version of BADIX. METHODS: Translation/retranslation of the English version of the BADIX was conducted, and the cross-cultural adaptation process performed. The Hebrew version BADIX was evaluated at two meetings, two weeks apart, in 51 female nurses (40 reported back pain and 11 reported no back problems). The Rolland Morris Disability Questionnaire (RMQ) and The Modified Oswestry Low Back Pain Disability Questionnaire (MODQ) were also evaluated. RESULTS: The mean age of the subjects was 45.34±11.11 years. Internal consistency calculated by the Cronbach's α coefficient was very high (α>0.9). A high degree of test-retest reliability was found, with an intraclass correlation coefficient (ICC) 95% CI) of 0.933 (0.839 - 0.973), and r=0.908. Concurrent validity of the BADIX domains with the RMQ and MODQ was found statistically significant and high (ρ=0.688, RMQ, and ρ=0.674, MODQ). CONCLUSIONS: The adapted and modified Hebrew version of the BADIX is reliable and measures the pain and mobility outcome of physical impairment and morning backache stiffness. It can be employed, in addition to self-reported outcome measures, by clinicians and researchers in quantitatively evaluating the clinical status and progression of patients with lower back pain in Hebrew-speaking populations.

RESUMO

BACKGROUND: Endometriosis is one of the most widespread gynecological disorders and a very common condition amongst fertile women, thus it has to be considered one of the possible sources of lumbopelvic pain. Endometriosis is commonly related to low back pain (LBP) and therefore often mistaken for a musculoskeletal disorder. The purpose of this case report is to underline the primary role of clinical reasoning and assessment process, which led the physiotherapist to the differential diagnosis, considering endometriosis among the possible causes of low back pain. CASE PRESENTATION: S.C, 45 years old, complained to physiotherapist of lumbar spine and left buttock pain, spreading to the hypogastric, inguinal and left pubic areas. The patient's past medical history included gynecological visceral disorders, regularly monitored. Functional evaluation and clinical tests revealed a disorder referred to the lumbar spine and sacroiliac region. Initial physical therapy management included education, manual therapy and therapeutic exercise. Nevertheless, after five treatment sessions, the symptoms remained unchanged, and therefore the patient was referred to a gynecologist for a consultation. The patient underwent a laparoscopy for endometriosis eradication and the intervention resulted in complete abolition of symptoms, enabling the patient to return to work and to do physical activities. CONCLUSIONS: this case report highlights the importance of a thorough clinical assessment and the identification of relevant findings from patient's medical history to be carried out by the physiotherapist. Those are of crucial importance to make an appropriate differential diagnosis and to screen amongst the possible causes of lumbopelvic pain also visceral ones as endometriosis, which often manifests with associated symptoms such as nonspecific LBP.

RESUMO

STUDY DESIGN: A cross-sectional study. OBJECTIVE: The purpose of this large cohort study was to assess the prevalence of low back pain (LBP) among young players participating in several types of sports. SUMMARY OF BACKGROUND DATA: LBP is a significant problem among young sports players. Sport discipline among young players is thought to be associated with LBP. However, similar previous studies did not specifically analyze LBP by age and sex. METHODS: A cross-sectional study was conducted with young sports players (ages 6-15 years, n = 7277) using a self-reported questionnaire. The prevalence of LBP was assessed using the variables of age, sex, and sport discipline. RESULTS: The point prevalence of LBP among young sports players was 5.0%. The participants between 6 and 8 years' old had the lowest prevalence of LBP (0.4%-1.3%), which increased with aging and reached the highest proportion of 13.5% to 14.8% at 13 to 14 years. Furthermore, female players had significantly higher proportions of LBP than male players (8.1% vs. 3.7%). Regarding sport discipline, the prevalence of LBP was higher in basketball, handball, and volleyball. CONCLUSION: The prevalence of LBP among young sports players was different for age, sex, and sport discipline. Further studies are needed to clarify the association of sport-specific movements to LBP in each sport discipline. This may assist in developing programs or strategies for preventing LBP among young sports players.Level of Evidence: 3.

RESUMO

BACKGROUND: Low back pain (LBP) is often a complex problem requiring interdisciplinary management to address patients' multidimensional needs. Providing inpatient care for patients with LBP in primary care hospitals is a challenge. In this setting, interdisciplinary LBP management is often unavailable during weekends. Delays in therapeutic procedures may result in a prolonged length of hospital stay (LoS). The impact of delays on LoS might be strongest in patients reporting high levels of psychological distress. Therefore, this study investigates the influence of weekday of admission and distress on LoS of inpatients with LBP. METHODS: This retrospective cohort study was conducted between 1 February 2019 and 31 January 2020. In part 1, a negative binomial model was fitted to LoS with weekday of admission as a predictor. In part 2, the same model included weekday of admission, distress level, and their interaction as covariates. Planned contrast was used in part 1 to estimate the difference in log-expected LoS between group 1 (admissions Friday/Saturday) and the reference group (admissions Sunday-Thursday). In part 2, the same contrast was used to estimate the corresponding difference in (per-unit) distress trends. RESULTS: We identified 173 patients with LBP. The mean LoS was 7.8 days (SD = 5.59). Patients admitted on Friday (mean LoS = 10.3) and Saturday (LoS = 10.6) had longer stays, but not those admitted on Sunday (LoS = 7.1). Analysis of the weekday effect and planned contrast showed that admission on Friday or Saturday was associated with a significant increase in LoS (log ratio = 0.42, 95% CI = 0.21 to 0.63). A total of 101 patients (58%) returned questionnaires, and complete data on distress were available from 86 patients (49%). According to the negative binomial model for LoS and the planned contrast, the distress effect on LoS was significantly influenced (difference in slopes = 0.816, 95% CI = 0.03 to 1.60) by dichotomic weekdays of admission (Friday/Saturday vs. Sunday-Thursday). CONCLUSIONS: Delays in interdisciplinary LBP management over the weekend may prolong LoS. This may particularly affect patients reporting high levels of distress. Our study provides a platform to further explore whether interdisciplinary LBP management addressing patients' multidimensional needs reduces LoS in primary care hospitals.

RESUMO

BACKGROUND: Distinctive features of low back pain-developers (LBPDs) as pre-clinical low back pain (LBP) population have been evidenced in three areas of alignment, muscle activation, and movement patterns. To clarify whether the reported altered functional movement patterns in chronic LBP patients result from or result in LBP disorders, LBPDs' functional movement patterns should be investigated. OBJECTIVES: This study aimed to compare female LBPDs' functional movement patterns with non-pain developers' (NPDs). METHODS: Sixty female LBPDs and NPDs were recruited based on the research requirements. The Functional Movement Screen (FMS) was used to investigate movement quality. Data were compared between groups via Mann-Whitney U tests and correlation analyses examined association between pain intensity and onset during prolonged standing and the FMS score. Receiver Operating Characteristic Curves and Chi Squares were conducted to find the best cutoff points. An alpha level of p≤0.05 was used to establish statistical significance. RESULTS: LBPDs scored significantly lower, or rather worse than NPDs in the FMS composite score (12.06±1.33 vs. 16.43±1.59, U = 3, P < 0.001). Moreover, the optimal cutoff scores of≤14 on the FMS, 2 on the push-up, and 1 on the deep squat discriminated between female LBPDs and NPDs. The FMS composite score was correlated negatively with LBP intensity (r (60) = -0.724, p < 0.001) and positively with LBP onset (r (60) = 0.277, p = 0.032) during prolonged standing. Finally, the results indicated that female LBPDs presented with at least one bilateral asymmetry on the FMS had 10 times (95% CI, 2.941-34.008) and with at least two bilateral asymmetries on the FMS had 15.5 times (95% CI, 3.814-63.359) higher odds of developing LBP during prolonged standing than NPDs. CONCLUSIONS: Female LBPDs, who are at higher risk for developing LBP in the future, have significantly lower quality of functional movement patterns compared to NPDs. Moreover, the FMS appears to show promise for predicting individuals who are at risk for LBP development during prolonged standing.

RESUMO

OBJECTIVE: To investigate the efficacy, acceptability, and safety of muscle relaxants for low back pain. DESIGN: Systematic review and meta-analysis of randomised controlled trials. DATA SOURCES: Medline, Embase, CINAHL, CENTRAL, ClinicalTrials.gov, clinicialtrialsregister.eu, and WHO ICTRP from inception to 23 February 2021. ELIGIBILITY CRITERIA FOR STUDY SELECTION: Randomised controlled trials of muscle relaxants compared with placebo, usual care, waiting list, or no treatment in adults (≥18 years) reporting non-specific low back pain. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently identified studies, extracted data, and assessed the risk of bias and certainty of the evidence using the Cochrane risk-of-bias tool and Grading of Recommendations, Assessment, Development and Evaluations, respectively. Random effects meta-analytical models through restricted maximum likelihood estimation were used to estimate pooled effects and corresponding 95% confidence intervals. Outcomes included pain intensity (measured on a 0-100 point scale), disability (0-100 point scale), acceptability (discontinuation of the drug for any reason during treatment), and safety (adverse events, serious adverse events, and number of participants who withdrew from the trial because of an adverse event). RESULTS: 49 trials were included in the review, of which 31, sampling 6505 participants, were quantitatively analysed. For acute low back pain, very low certainty evidence showed that at two weeks or less non-benzodiazepine antispasmodics were associated with a reduction in pain intensity compared with control (mean difference -7.7, 95% confidence interval-12.1 to-3.3) but not a reduction in disability (-3.3, -7.3 to 0.7). Low and very low certainty evidence showed that non-benzodiazepine antispasmodics might increase the risk of an adverse event (relative risk 1.6, 1.2 to 2.0) and might have little to no effect on acceptability (0.8, 0.6 to 1.1) compared with control for acute low back pain, respectively. The number of trials investigating other muscle relaxants and different durations of low back pain were small and the certainty of evidence was reduced because most trials were at high risk of bias. CONCLUSIONS: Considerable uncertainty exists about the clinical efficacy and safety of muscle relaxants. Very low and low certainty evidence shows that non-benzodiazepine antispasmodics might provide small but not clinically important reductions in pain intensity at or before two weeks and might increase the risk of an adverse event in acute low back pain, respectively. Large, high quality, placebo controlled trials are urgently needed to resolve uncertainty. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019126820 and Open Science Framework https://osf.io/mu2f5/.

RESUMO

BACKGROUND: Although many people with chronic low back pain (LBP) improve following conservative treatment, one in five will experience worsening symptoms after discharge from treatment and seek health care again. The current LBP clinical care pathway in many health services lacks a well-integrated, systematic approach to support patients to remain physically active and self-manage their symptoms following discharge from treatment. Health coaching can support people to improve physical activity levels and may potentially reduce health care utilisation for LBP. The primary aim of this study is to evaluate the effect of introducing a coordinated support system (linking hospital outpatient physiotherapy services to a public health coaching service) at discharge from LBP treatment, on the future use of hospital, medical, and health services for LBP, compared with usual care provided at discharge. METHODS: Three hundred and seventy-four adults with chronic non-specific LBP will be recruited from the outpatient physiotherapy departments of public hospitals in New South Wales, Australia. Participants will be individually randomised to a support system (n = 187) or usual care group (n = 187). All participants will receive usual care provided at discharge from treatment. Participants allocated to the support system will also receive up to 10 telephone-based health coaching sessions, delivered by the Get Healthy Service®, over a 6-month period. Health coaches will monitor and support participants to improve physical activity levels and achieve personal health-related goals. The primary outcome is the total number of encounters with hospital, medical, and health services for LBP, at 12 months from baseline. A within-trial economic evaluation will quantify the incremental costs and benefits of the support system from a health system perspective, to support reimbursement decision making. DISCUSSION: This study will establish the effect of a coordinated support system, introduced at discharge from treatment, on the future use of hospital, medical, and health services for LBP and various health outcomes. CONCLUSION: Innovative community-driven solutions to support people with chronic LBP after discharge from treatment are urgently needed. Study findings will help inform health care policy and clinical practice in Australia.

RESUMO

ABSTRACT: To investigate the effect of core stability training on nonspecific low back pain (NSLBP) in nurses.The data were collected retrospectively by reviewing the patient's medical records and pain questionnaires in our rehabilitation center. A total of 40 nurses with NSLBP were included and divided into observation group and control group. Each group were given routine health education for NSLBP. Core stability training was performed in observation group for 4 weeks. Surface electromyography (sEMG) evaluation of erector spine and multifidus muscle, pain Numeric Rating Scale (NRS) and Japanese Orthopaedic Association (JOA) scores were evaluated and analyzed before and 4 weeks after intervention.There was no significant difference of NRS score and JOA score between two groups before intervention (P > .05, respectively). The NRS and JOA scores were significantly improved in both two groups after 4 weeks of intervention (P < .05, respectively). Moreover, the improvement of NRS and JOA scores in the observation group were better than those of the control group (P < .05, respectively). No significant difference of average electromyography (AEMG) or median frequency (MF) were noted between the healthy side and the affected side in both groups before or after intervention (P > .05, respectively). After 4 weeks of intervention, the AEMG of the healthy and the affected side of the two groups showed an improved trend without significant difference (P > .05, respectively). The MF of affected side was significantly higher 4 weeks after intervention than those before treatment in the observation and control group (P < .05, respectively).Core stability training can alleviate pain, improve the fatigue resistance of the core muscles and the balance of the functions of bilateral multifidus muscles in nurses with NSLBP.

RESUMO

RATIONALE: For isthmic lumbar spondylolisthesis (ILS) associated with the removal of herniation, it remains challenging to perform less invasive and minimally disruptive procedures. Good results could potentially be obtained by further preserving the posterior elements in full-endoscopic lumbar discectomy (FESS), which is less invasive than microenscopic surgery (MES). PATIENT CONCERNS: One patient complained of left leg pain, and another patient complained of right leg pain and low back pain. DIAGNOSES: Two patients with ILS and Meyerding Grade 1 lumbar spondylolisthesis. INTERVENTIONS: We performed a full-endoscopic lumbar discectomy via the interlaminar space (FESS-IL) for L5/S1 lumbar disc herniation (LDH) accompanied by isthmic lumbar spondylolisthesis. FESS-IL was performed in 2 patients with radiculopathy caused by different types of LDH using a full endoscopic system with a 4.1 mm working channel and 6.9 mm outer diameter. A 3.5-mm diameter high-speed drill was used in one patient for an upward-migrated LDH in the inner-rim of the infravertebral border. The other patient underwent minimal resection without bone resection. OUTCOMES: The one-year clinical outcome included confirmation of pain relief and evacuation of migrated LDH on magnetic resonance imaging in all patients. There was no progression of slippage on radiography. The mean operative time was 82 min, and no complication was observed. The one-year clinical outcome demonstrated sufficient pain relief. LESSONS THE Y: ear postoperative outcome showed improvement. We believe that FESS-IL is a viable alternative operative approach for LDH for ILS.

RESUMO

Low back pain covers a spectrum of different types of pain (eg, nociceptive, neuropathic and nociplastic, or non-specific) that frequently overlap. The elements comprising the lumbar spine (eg, soft tissue, vertebrae, zygapophyseal and sacroiliac joints, intervertebral discs, and neurovascular structures) are prone to different stressors, and each of these, alone or in combination, can contribute to low back pain. Due to numerous factors related to low back pain, and the low specificity of imaging and diagnostic injections, diagnostic methods for this condition continue to be a subject of controversy. The biopsychosocial model posits low back pain to be a dynamic interaction between social, psychological, and biological factors that can both predispose to and result from injury, and should be considered when devising interdisciplinary treatment plans. Prevention of low back pain is recognised as a pivotal challenge in high-risk populations to help tackle high health-care costs related to therapy and rehabilitation. To a large extent, therapy depends on pain classification, and usually starts with self-care and pharmacotherapy in combination with non-pharmacological methods, such as physical therapies and psychological treatments in appropriate patients. For refractory low back pain, a wide range of non-surgical (eg, epidural steroid injections and spinal cord stimulation for neuropathic pain, and radiofrequency ablation and intra-articular steroid injections for mechanical pain) and surgical (eg, decompression for neuropathic pain, disc replacement, and fusion for mechanical causes) treatment options are available in carefully selected patients. Most treatment options address only single, solitary causes and given the complex nature of low back pain, a multimodal interdisciplinary approach is necessary. Although globally recognised as an important health and socioeconomic challenge with an expected increase in prevalence, low back pain continues to have tremendous potential for improvement in both diagnostic and therapeutic aspects. Future research on low back pain should focus on improving the accuracy and objectivity of diagnostic assessments, and devising treatment algorithms that consider unique biological, psychological, and social factors. High-quality comparative-effectiveness and randomised controlled trials with longer follow-up periods that aim to establish the efficacy and cost-effectiveness of low back pain management are warranted.
