ABSTRACT
We investigated the effect of two dynamic seat cushions on postural shift, trunk muscle activation and spinal discomfort. In this repeated-measures study, 30 healthy office workers were randomly assigned to a sequence of three conditions: sitting on a dynamic seat cushion-A, cushion-B and control (no seat cushion). The two dynamic seat cushions had different inflation levels. Participants typed a standard text for an hour and were monitored for postural shift by using a seat pressure mat, transversus abdominis/internal oblique and lumbar multifidus muscles activity by using surface EMG, spinal discomfort by using Borg's CR-10 scale. Two-way repeated ANOVAs showed no statistically significant interaction effects between condition and time on postural shift and muscle activation. Post hoc Bonferroni tests showed that postural shifts and lumbar multifidus activation during sitting on cushion-A were significantly higher (p < 0.01) than in the control and cushion-B conditions. Both cushions reduced spinal discomfort, compared to the control condition (p < 0.05).

BACKGROUND: Clinical practice guidelines stress the importance of prevention and treatment of non-specific back pain through exercise therapy. However, it has not yet been confirmed whether the combination of exercise plus education is more effective than such interventions taken separately. OBJECTIVE: To determine if the combination of exercise plus education is more effective for the prevention of non-specific back pain than exercise or education alone. METHOD: A systematic search of studies whose sample consisted of participants without non-specific back pain (primary prevention) and participants with non-specific back pain (secondary and tertiary prevention) was conducted in the following databases in March 2023: PubMed, Scopus, Web of Science and Medline. RESULTS: A total of 16 articles were selected. Statistically significant results were found in the pain variable with SMD =-2.02 (95% CI =-2.71 to -1.33; p< 0.001), the disability variable with SMD =-1.14 (95% CI =-1.63 to -0.65; p< 0.001), and the kinesiophobia variable with SMD =-1.8 (95% CI =-2.54 to -1.05; p< 0.001). CONCLUSION: Interventions that combine exercise and education seem to have a greater preventive effect on non-specific back pain, disability and kinesiophobia than those that include exercise or education in an isolated manner.

Chronic lower back (CLB) pain limits patients' day-to-day activities, increases their missed days of work, and causes emotional distress. Developing adequate and individual-tailored treatment for CLB patients requires a better understanding of pain and protective behaviors, and how these behaviors are modulated or altered by context and subjectivity. In this work, we conducted experiments to investigate 1) the relationship between pain and protective behaviors in patients with CLB pain, 2) whether individual differences and context are relevant factors in the relationship, and 3) the impact of this relationship and its factors on the performance of current automated models for pain and protective behavior perception. Our results show 1) significant association (p - value < 0.05) between pain and protective behaviors in patients with CLB pain and 2) subjectivity and context are influential factors in this association. Further, our results show that considering this association along with its factors significantly (p-value < 0.05) improves the performance of automated pain and protective behaviors perception. These findings highlight the role of this association on pain and protective behaviors perception and raise several questions about the robustness of existing automated models that do not take this association into account.

BACKGROUND: Many studies show a higher prevalence of back pain for dentists and dental students than in the general population. This leads to a need to integrate an effective back pain prevention program (BPPP) into the student's curriculum. We have implemented such a program for 10 years, and the objective was to evaluate its effectiveness. MATERIAL AND METHODS: Data from 102 dentists and students who benefited from the BPPP were collected. Back pain prevalence and its intensity (0-10 scale) regarding neck, upper back and lower back location were studied, as well as sex, age, implementation or not of elements of the BPPP into daily practice, and if so at what moment of the professional life. For identical items, answers were compared with those from a national survey conducted amongst French students and practitioners in 2018. RESULTS: Amongst the BPPP beneficiaries, 60% were suffering from chronic back pain versus 77% in the previous national survey (p < .001). Mean pain intensity was lower in each location for the BPPP beneficiaries on the 0-10 scale: neck 1.91 vs. 2.40 (p = .05); upper back 1.94 vs. 2.72 (p < .001); lower back 2.26 vs. 2.67 (p = .15). Respondents who implemented elements of the BPPP from the start of their clinical practice showed a prevalence of chronic back pain of 48.4%, against 77% for respondents who did so only from the first year or after (p < .05). CONCLUSION: Our BPPP seems to show a positive preventive effect on dentists and students after a 10-year implementation. It is a solid basis that can however be further improved.

INTRODUCTION: The need for an interdisciplinary multimodal approach to the treatment of back pain has already been demonstrated by various studies. However, when considering the periods of incapacity to work in the longitudinal course after the multimodal pain therapy (MPT), limits in terms of its sustainable effect become clear. Patients who receive MPT subsequently return to standard outpatient care, which is associated with a risk of relapse. A 12-month relapse prophylaxis (RP) programme, intended to follow a 4-week MPT, was developed to help patients make the transition to health-conscious and physically active behaviour in everyday life and to identify and prevent impending relapses at an early stage. The evaluation, based on a cluster randomised controlled trial, seeks to provide information on the benefits of early and intensive RP as part of MPT, examine whether it is cost effective, reduces the days of incapacity to work and increases functional capacity, as well as to examine other parameters. METHODS AND ANALYSIS: The study population comprises members of a regional statutory health insurance fund in Germany, who are ≤62 years old, gainfully employed and have been incapacitated for work for at least 21 days due to a diagnosis of back pain. Over a recruitment period of 24 months, a maximum of 368 individuals can potentially be included in the MPT. The intervention group (IG) and control group (CG) will both receive MPT, after randomisation IG will receive RP and CG will receive no further therapy or support as part of the trial. The evaluation is carried out on the following levels: structural, process and results quality. Cost effectiveness is also assessed by means of a health economic evaluation. In addition to the collection of qualitative and quantitative primary data, claims data from the regional health insurance fund are also included in the analysis. ETHICS AND DISSEMINATION: This study has received approval by the ethics committee of the Hannover Medical School (reference number: 8548_BO_S_2019). The study results will be disseminated in national and international journals and conference presentations. TRIAL REGISTRATION NUMBER: DRKS00017654.

Low Back Pain - Value of Prevention and Physiotherapy? Abstract. Physiotherapy plays a central role in the prevention and treatment of lumbar back pain. There is no clear evidence in science on the effectiveness of individual preventive measures; however, movement and active training as central elements are indispensable here. In the treatment of lumbar back pain, however, the picture is clear: while passive measures such as heat or cold applications as well as ultrasound and electrotherapy should no longer be used alone due to the lack of evidence, the combination of active exercises and patient education shows promising success. If these are supplemented by sporadically applied manual therapy methods, the result is an evidence-based management of both acute and chronic lumbar back pain. One example of a successful implementation of current evidence for the treatment of back pain is GLA:D®, which is also in use in Switzerland since 2021.

OBJECTIVE: The mechanisms of change in digital interventions for the prevention of depression are largely unknown. Here, we explored whether five theoretically derived intervening variables (i.e., pain intensity, pain-related disability, pain self-efficacy, quality of life [QoL], and work capacity) were mediating the effectiveness of a digital intervention specifically designed to prevent depression in patients with chronic back pain (CBP). METHOD: This study is a secondary analysis of a pragmatic, observer-masked randomized clinical trial conducted at 82 orthopedic clinics in Germany. A total of 295 adults with a diagnosis of CBP and subclinical depressive symptoms were randomized to either the intervention group (n = 149) or treatment-as-usual (n = 146). Longitudinal mediation analyses were conducted with structural equation modeling and depression symptom severity as primary outcome (Patient Health Questionnaire-9 [PHQ-9]; 6 months after randomization) on an intention-to-treat basis. RESULTS: Beside the effectiveness of the digital intervention in preventing depression, we found a significant causal mediation effect for QoL as measured with the complete scale of Assessment of Quality of Life (AQoL-6D; axb: -0.234), as well as for the QoL subscales mental health (axb: -0.282) and coping (axb: -0.249). All other potential intervening variables were not significant. CONCLUSION: Our findings suggest a relevant role of QoL, including active coping, as change mechanism in the prevention of depression. Yet, more research is needed to extend and specify our knowledge on empirically supported processes in digital depression prevention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUND: Clinical practice guidelines emphasize the importance of the prevention and treatment of non-specific back pain through exercise therapy and health education. However, it has not yet been confirmed that the combination of exercise plus education is more effective than usual medical care. OBJECTIVE: The aim of this study was to determine if the combination of exercise plus education is more effective for the prevention of non-specific back pain than usual medical care. MATERIALS AND METHODS: A systematic search in PubMed, Scopus, Web of Science and Medline was conducted with the terms Back Pain, Neck Pain, Musculoskeletal Pain, Exercise, Exercise Therapy, Health Education, Cognitive Behavioral Therapy, Primary Prevention, Secondary Prevention and Clinical Trial. The inclusion criteria were: articles published from 2016 to 2021, the intervention included exercise and education, and the sample consisted of non-specific back pain patients. RESULTS: A total of 4 randomized controlled trials were selected (average PEDro score 6.5 points). The meta-analysis showed statistically significant differences in the pain intensity, standardized mean differences was found to be -0.75 (95% CI = -1.41 to -0.08; p = 0.03); and in disability, standardized mean differences was found to be -0.24 (95% CI = -0.38 to -0.1; p = 0.001). CONCLUSIONS: Interventions combining exercise and education seem to have a greater preventive effect on non-specific back pain than usual medical care.Key messagesExercise therapy and health education combination prevent better non-specific back pain than usual care.Combining exercise with educational interventions has a higher improvement on disability and kinesophobia than usual care.

BACKGROUND: Depression is a common comorbid condition in individuals with chronic back pain (CBP), leading to poorer treatment outcomes and increased medical complications. Digital interventions have demonstrated efficacy in the prevention and treatment of depression; however, high dropout rates are a major challenge, particularly in clinical settings. OBJECTIVE: This study aims to identify the predictors of dropout in a digital intervention for the treatment and prevention of depression in patients with comorbid CBP. We assessed which participant characteristics may be associated with dropout and whether intervention usage data could help improve the identification of individuals at risk of dropout early on in treatment. METHODS: Data were collected from 2 large-scale randomized controlled trials in which 253 patients with a diagnosis of CBP and major depressive disorder or subclinical depressive symptoms received a digital intervention for depression. In the first analysis, participants' baseline characteristics were examined as potential predictors of dropout. In the second analysis, we assessed the extent to which dropout could be predicted from a combination of participants' baseline characteristics and intervention usage variables following the completion of the first module. Dropout was defined as completing <6 modules. Analyses were conducted using logistic regression. RESULTS: From participants' baseline characteristics, lower level of education (odds ratio [OR] 3.33, 95% CI 1.51-7.32) and both lower and higher age (a quadratic effect; age: OR 0.62, 95% CI 0.47-0.82, and age2: OR 1.55, 95% CI 1.18-2.04) were significantly associated with a higher risk of dropout. In the analysis that aimed to predict dropout following completion of the first module, lower and higher age (age: OR 0.60, 95% CI 0.42-0.85; age2: OR 1.59, 95% CI 1.13-2.23), medium versus high social support (OR 3.03, 95% CI 1.25-7.33), and a higher number of days to module completion (OR 1.05, 95% CI 1.02-1.08) predicted a higher risk of dropout, whereas a self-reported negative event in the previous week was associated with a lower risk of dropout (OR 0.24, 95% CI 0.08-0.69). A model that combined baseline characteristics and intervention usage data generated the most accurate predictions (area under the receiver operating curve [AUC]=0.72) and was significantly more accurate than models based on baseline characteristics only (AUC=0.70) or intervention usage data only (AUC=0.61). We found no significant influence of pain, disability, or depression severity on dropout. CONCLUSIONS: Dropout can be predicted by participant baseline variables, and the inclusion of intervention usage variables may improve the prediction of dropout early on in treatment. Being able to identify individuals at high risk of dropout from digital health interventions could provide intervention developers and supporting clinicians with the ability to intervene early and prevent dropout from occurring.

Background: Vertebral compression fractures (VCFs) often occur in patients with osteoporosis. These fractures can also lead to postural changes. Several studies have shown that patients with vertebral compression fractures have a restrictive pattern in their pulmonary function. Percutaneous vertebroplasty (PVP) is the standard treatment for vertebral compression fractures, with the benefits of pain relief and enhancement of vertebral stability for partially collapsed vertebral bodies. However, the effects of PVP on short-term recovery of respiratory performance have not been investigated. Therefore, this study aimed to investigate the changes in pulmonary function, respiratory muscle strength, maximal voluntary ventilation (MVV), and chest mobility in patients with vertebral compression fractures after PVP.Methods: This research was approved by the clinic committee of the E-DA Hospital Institutional Review Board (EMRP07109N) and registered in the Thai Clinical Trials Registry (TCTR20211029005). We recruited 32 VCF patients. Four-time points were measured: before and after PVP and 1 and 3 weeks after PVP. We measured pulmonary function and maximum voluntary ventilation (MVV) by using spirometry. Respiratory muscle strength was assessed by using a respiratory pressure meter. The chest expansion test was used to evaluate chest mobility. A visual analogue scale (VAS) was used to assess resting and aggravated back pain.Results: Chest expansion and back pain improved at each time point after PVP. MVV showed significant progress at both 1 and 3 weeks after discharge. Forced expiratory volume in 1 second (FEV1) and maximal inspiratory muscle strength significantly improved 1 week after discharge.Conclusion: Taking all the data together, PVP not only can resolve severe back pain but can also provide excellent improvements in MVV and chest mobility in patients with vertebral compression fractures.

A systematic review was conducted to assess the efficacy and effectiveness of education programs to prevent and treat low back pain (LBP) in the Hispanic cultural setting. Electronic and manual searches identified 1148 unique references. Nine randomized clinical trials (RCTs) were included in this review. Methodological quality assessment and data extraction followed the recommendations from the Cochrane Back Pain Review Group. Education programs which were assessed focused on active management (3 studies), postural hygiene (7), exercise (4) and pain neurophysiology (1). Comparators were no intervention, usual care, exercise, other types of education, and different combinations of these procedures. Five RCTs had a low risk of bias. Results show that: (a) education programs in the school setting can transmit potentially useful knowledge for LBP prevention and (b) education programs for patients with LBP improve the outcomes of usual care, especially in terms of disability. Education on pain neurophysiology improves the results of education on exercise, and education on active management is more effective than "sham" education and education on postural hygiene. Future studies should assess the comparative or summatory effects of education on exercise, education on pain neurophysiology and education on active management, as well as explore their efficiency.

Back pain and its ailments are the main cause of absenteeism and sick leave. Furthermore, the cause of pain and disability in a large number of workers is unknown, and treatments are not effective in controlling it. For this reason, the Back Schools (BSs) provide theoretical and practical training to workers so that they can acquire knowledge and skills that will allow them to adequately manage their back problems, enabling them to recover their autonomy and prevent relapses. The aim of the study is to analyse the efficacy of a BS by means of the evaluation of pain and disability scales in workers in different sectors and in construction. The most important clinical benefits obtained after the intervention of a BS are the reduction of pain and disability. Statistically significant and clinically relevant results have been observed between the initial assessment and the 6-month review. BS has been shown to be effective in reducing low back and neck pain and disability during the first 6 months of follow-up. Construction workers have pain and disability rates at the overall mean and with improvements between the initial assessment and the 6-month review. Their rates of improvement are clinically more relevant than for the overall population analysed.

OBJECTIVES: There is scarce information on preventive psychological and behavioural methods applicable to sub-acute (4-12 weeks) back pain, a precursor to chronic back pain. We conducted a systematic literature review of the efficacy of psychological interventions in preventing chronicity of sub-acute back pain. METHODS: A systematic literature search in CINAHL, CENTRAL, MEDLINE, PubMed®, PsychINFO, Scopus and Web of Science databases. RESULTS: From a total of 271 records, only three studies met the eligibility criteria. In two of the reviewed studies, the interventions had an insignificant preventive impact on the chronification of back pain. In one study the CBT intervention proved promising in preventing back pain related disability. None of the studies reported a significant impact on pain intensity at follow-up. CONCLUSIONS: The psychological interventions did not impact pain outcomes. There is a disproportion between novel knowledge on psychological factors involved in the transition to chronic pain and corresponding preventive treatments. Additional studies on psychological interventions on sub-acute back pain prevention are highly warranted due to the enormous burden that back pain creates when it becomes chronic. The research project has the ethical approval of the Research Ethical Committee at Helsinki University Hospital, HUS/2435/2017.

Energy spent during daily activities is recuperated by humans through sleep, ensuring optimal performance on the following day. Sleep disturbances are common: a meta-analysis on sleep quality showed that 15-30% of adults report sleep disorders, such as sleep onset latency (SOL), insufficient duration of sleep and frequently waking up at night. Low back pain (LBP) has been identified as one of the main causes of poor sleep quality. Literature findings are discordant on the type of mattress that might prevent onset of back pain, resulting in an improved quality of sleep. We conducted a systematic literature review of articles published until 2019, investigating the association of different mattresses with sleep quality and low back pain. Based on examined studies, mattresses were classified according to the European Committee for Standardization (2000) as: soft, medium-firm, extra-firm or mattresses customized for patients affected by supine decubitus. A total of 39 qualified articles have been included in the current systematic review. Results of this systematic review show that a medium-firm mattress promotes comfort, sleep quality and rachis alignment.

OBJECTIVE: At school age pain in the lower back is common. There is evidence that an adequate fit between the dimensions of the school furniture and the anthropometric characteristics will result in an improvement in their posture and a reduction in pain. The objectives of this research were to determine the degree of mismatch of furniture in primary education, check if the sizes of the current regulations are adequate and validate two instruments that allow teachers to correctly assign furniture. METHODS: 92 elementary students participated. Measurements to determine the ideal height of the chair and table were made with an anthropometer in a Galician public school in 2019. The recorded values were compared with those obtained by the two measurement instruments to be validated: TAIS and TAIM. The analysis techniques used were: descriptive, one-way ANOVA, t-test and effect size, significance level ρ<0.05. RESULTS: The mismatch between the furniture used in the classrooms and that calculated as ideal was 93.5% for chairs and 97.6% for tables. In 51% of cases they needed different chair and table sizes. The correlational analysis of the instruments to be validated showed an r=0.994 in the chair and r=0.99 in the table. CONCLUSIONS: The level of mismatch between the furniture and the anthropometric dimensions of the students was high. A reorganization of the sizes in the classroom is necessary, being able to follow the European size regulations and using furniture allocation instruments such as those proposed for their high level of correlation.
OBJETIVO: En edad escolar es común el dolor en la zona lumbar. Existe evidencia de que un ajuste adecuado entre las dimensiones del mobiliario escolar y las características antropométricas repercutirá en una mejora en su postura y reducción del dolor. Los objetivos de esta investigación fueron determinar el grado de desajuste del mobiliario en educación primaria, comprobar si las tallas de las normativas vigentes son adecuadas y validar dos instrumentos que permitan al profesorado una correcta asignación del mobiliario. METODOS: Participaron 92 estudiantes de primaria. Las mediciones para determinar la altura ideal de la silla y la mesa se efectuaron con un antropómetro en un centro público gallego en 2019. Los valores registrados se compararon con los obtenidos por los dos instrumentos de medición a validar: TAIS y TAIM. Las técnicas de análisis empleadas fueron: descriptivo, ANOVA de un factor, prueba t y tamaño del efecto, nivel de significación ρ<0,05. RESULTADOS: El desajuste entre el mobiliario utilizado en las aulas y el calculado como ideal fue del 93,5% en las sillas y 97,6% en las mesas. En un 51% de los casos necesitaron tallas de silla y mesa diferente. El análisis correlacional de los instrumentos a validar mostró un r=0,994 en silla y r=0,99 en mesa. CONCLUSIONES: El nivel de desajuste entre el mobiliario y las dimensiones antropométricas del alumnado fue elevado. Es necesaria una reorganización de las tallas en el aula, pudiendo seguir la normativa de tallas europea y empleando instrumentos de asignación de mobiliario como los propuestos por su alto nivel de correlación.

BACKGROUND: Back pain is common in secondary school students. If we adjust the school furniture to the anthropometric characteristics of the pupils, we will improve their posture and reduce back pain. There is a high degree of mismatch between the furniture used by students and that which should be used. The objectives of this research are to discover the degree of mismatch and validate two instruments that allow a correct allocation of the furniture. METHODS: The selected sample was 132 secondary students (14.08 ± 1.10 years). An anthropometer was used to determine the ideal height of the chair and table; data were taken from body segments. The recorded values were compared with those obtained by the two measurement instruments to be validated. Inter-measurer and intra-measurer reliability and validation were performed using t-tests and Pearson's coefficient, respectively. Different analysis techniques were used: descriptive, one-way ANOVA, t-test, and effect size. The established level of significance was ρ < 0.05. RESULTS: The mismatch between the anthropometric dimensions of the students and the existing furniture in the classrooms was 98.5 % for the chairs and 100 % for the tables. The correlational analysis of the instruments to be validated shows an r = 0.993 in the chair and r = 0.996 in the table. CONCLUSIONS: There is a high degree of mismatch between the furniture and the anthropometric characteristics of the students. The proposed furniture allocation instruments are adequate.

OBJECTIVE: To assess the role of exercise targeting proper trunk stabilization and segmental spinal movement in back pain and sensory perception among cross-country skiers. DESIGN: Randomized, controlled trial with blinded outcome assessors. SETTING: University Hospital, Department of Rehabilitation and Sports Medicine. PARTICIPANTS: Twenty elite cross-country skiers aged 17 to 27 years. INTERVENTIONS: Ten cross-country skiers integrated 3 types of exercise targeting segmental motion in mid-thoracic spine into their routine training practice for 2 months. The 10 controls performed routine athletic training. MAIN OUTCOME MEASURES: The Young Spine Questionnaire to measure intensity and frequency of back pain was completed at the start and end of study. Tactile sensory perception using 10-g Semmes-Weinstein monofilament, thermic perception using TIP THERM device, graphesthesia assessed by a touch monitor pencil, 2-point discrimination assessed by a digital caliper, and vibration perception assessed by a 128-Hz tuning fork measured in mid-thoracic spine 5 times. RESULTS: No significant group differences in pain and sensory perception were identified at baseline. Over the 2-month study interval, repeated-measures analysis of variance revealed that the experimental group improved significantly relative to the control group on pain intensity (P = 0.005 for cervical, P = 0.004 for thoracic, and P = 0.014 for lumbar) and frequency of pain in the thoracic area only (P = 0.011). Improvements were also observed in the experimental relative to control group on graphesthesia (P < 0.001), vibration perception (P = 0.002), and 2-point discrimination (P < 0.001). CONCLUSIONS: Exercise targeting the mid-thoracic spine may decrease back pain and improve sensory perception in cross-country skiers. LEVEL OF EVIDENCE: Original research, level I.

INTRODUCCIÓN Y OBJETIVO: El dolor de cuello y/o espalda (DCE) es uno de los trastornos musculoesquéleticos que más carga social y económica supone en los maestros. El objetivo de este estudio fue determinar la necesidad de intervención preventiva sanitaria percibida por este colectivo. MATERIAL Y MÉTODOS: Estudio transversal en la comunidad en una provincia española. Participaron maestros de educación infantil y primaria. Se utilizó un cuestionario anónimo autoadministrado redactado en español que incluía información sobre el dolor, datos sociodemógráficos, laborales y del estilo de vida, tratamientos y perspectivas de participación en programas de educación sanitaria. RESULTADOS: Se analizaron 311 cuestionarios. La prevalencia actual del DCE fue 76,8% (n = 239), OR mujer/hombre 2,99 [IC 95% 1,66-5,36]). El 59% presentaba DCE desde hace más de 5 años. El 22,6% había tenido alguna incapacidad temporal por el DCE. No se encontró relación significativa entre el dolor y la edad, ni nivel de educación o tipo de profesor. El 38,1% disponían de diagnóstico médico y el 69,9% había recibido tratamiento alguna vez. El 60,9% atribuía el DCE a posturas incorrectas y el 75,7% mostró predisposición para participar en un programa de educación para la salud. CONCLUSIONES: La alta prevalencia del DCE en maestros justifica poner en marcha protocolos viables de educación para la salud destinados a disminuir la incidencia e intensidad de los episodios de dolor en este colectivo, mejorar su calidad de vida y su rendimiento laboral
INTRODUCTION AND OBJECTIVE: Neck and/or back pain (NBP) is a musculoskeletal disorder that has become one of the greatest social and economic burdens afflicting teachers. The aim of the study was to determine the need for preventative healthcare among teachers. MATERIAL AND METHODS: A community-based cross-sectional study was carried out in a Spanish province. Elementary and preschool teachers at all schools within the province participated. An anonymous self-administered ad hoc questionnaire written in Spanish including information about pain, sociodemographic and work data, lifestyle, treatments and perspectives on participation in health education programmes was used. RESULTS: 311 questionnaires were analysed. The current prevalence of NBP was 76.8%, female/male OR 2.99 [95%CI 1.66-5.36]). Fifty-nine percent had presented symptoms of NBP for more than 5 years. Also 22.6% had experienced some type of temporary disability due to NBP. No significant correlation was found between pain and age, grade level taught or type of teacher. Of all the respondents, 38.1% had received a medical diagnosis and 69.9% had received treatment at some point. Almost two thirds (60.9%) attributed their NPB to incorrect posture and 75.7% indicated a willingness to participate in a health education programme. CONCLUSIONS: The high prevalence of NBP among teachers warrants the application of viable protocols for health education aimed at diminishing the incidence and intensity of pain among this professional group, improving their quality of life and professional productivity

PURPOSE: To assess the safety and efficacy of multilevel thoracolumbar vertebroplasty in the simultaneous treatment of ≥ 6 painful pathologic compression fractures. MATERIALS AND METHODS: Retrospective review was conducted of 50 consecutive patients treated with vertebroplasty for ≥ 6 pathologic compression fractures in a single session for pain palliation at a tertiary single cancer center from 2015 to 2019. Outcomes measured included procedural safety according to Common Terminology Criteria for Adverse Events (CTCAE), change in 4-week postprocedure back pain by numeric rating scale (NRS), comparison of daily opioid medication consumption, and development of skeletal-related events. RESULTS: A total of 397 pathologic compression fractures were treated during 50 sessions (mean, 7.9 per patient ± 1.5). Mean procedure duration was 162 minutes ± 35, mean postoperative hospitalization duration was 1.6 days ± 0.9, and mean follow-up duration was 401 days ± 297. Seven complications were recorded, including 1 case of symptomatic polymethyl methacrylate pulmonary embolism. No major complications (CTCAE grade 4/5) were reported. NRS pain score was significantly decreased (5.0 ± 1.8 vs 1.7 ± 1.4; P < .0001), with a mean score decrease of 3.3 points (66%). Opioid agent use decreased significantly (76 mg/24 h ± 42 vs 45 mg/24 h ± 37; P = .0003), with a mean decrease of 30 mg/24 h (39%). Skeletal-related events occurred in 7 patients (14%). CONCLUSIONS: Multilevel vertebroplasty for ≥ 6 pathologic compression fractures is safe and provides significant palliative benefit when performed simultaneously.

Back-support exoskeletons (BSEs) are wearable systems designed to reduce physical demands on the back, but which could have undesired effects beyond this design intention. Participants (n = 18) used two commercial BSEs to complete a brief (~15-20 s) simulated manual assembly task in varying conditions, with outcome measures that included: working posture, activity levels in "secondary" muscle groups (shoulders and thighs), perceived balance, discomfort, and usability. Using a BSE led to small and inconsistent changes in working postures (e.g., < ~14° change in lumbar flexion), muscular activity in the secondary muscle groups (<±2% of maximum voluntary isometric contractions), or perceived balance. Limitations in movement were reported for both BSEs, however, along with moderate levels of discomfort. Task-specific responses were evident for all outcome measures, though these depended on the specific BSE used and differed between genders in many cases. Future work should focus on interactions between a given user, BSE design, and task conditions.
