Purpose and Background

Work-related musculoskeletal disorders (WRMSD) can affect 56–80% of physiotherapists. Patient handling is reported as a significant risk factor for developing WRMSD with the back most frequently injured. Physiotherapists perform therapeutic handling to manually assist and facilitate patients’ movement to aid rehabilitation, which can increase physiotherapists risk of experiencing high forces during patient handling.

A Core Outcome Set (COS) for treatment of adolescent idiopathic scoliosis (AIS) is essential to ensure that the most meaningful outcomes are evaluated and used consistently. Measuring the same outcomes ensures evidence from clinical trials and routine clinical practice of different treatments can be more easily compared and combined, therefore increasing the quality of the evidence base. The SPINE-COS-AYA project aims to develop a gold standard COS which can be used internationally in research and routine clinical practice to evaluate the treatment (surgical and bracing) of AIS.

In this qualitative study, the views of adolescents and young adults with AIS (10-25 years of age), their family members and healthcare professionals in a UK region were sought, via interviews, on treatment outcomes. Participants were purposively recruited from a variety of sources including NHS outpatient clinics and social media. Semi-structured interviews were analysed using thematic analysis.

Key findings will be presented, to include potential core outcome domains identified by the different subgroups.

The core outcome domains identified in this research programme will subsequently form part of an international consensus survey to agree a COS. In future, if the COS is used by healthcare staff and researchers, it will be easier for everyone, including patients and their families, to assess which treatment works best.

Purpose

Clinical guidelines identify a clear role for managing back pain with structured exercise. Pilates is a commonly recommended modality, however, Pilates-specific research is limited. Research suggests the patient-practitioner relationship may be important in managing persistent low back pain, although further research is needed to evaluate its impact on outcomes. The purpose of this study was to identify the components of the relationship between Pilates teachers and clients with persistent low back pain.

Purpose of study

Cauda Equina Syndrome (CES) is a surgical emergency. With Physiotherapists increasingly taking on first-contact and spinal triage roles, screening for CES must be as thorough and effective as possible. This study explores whether Physiotherapists are asking the correct questions, in the correct way and investigates their experiences when screening for this serious condition.

Aims. Degenerative cervical spondylosis (DCS) is a common musculoskeletal disease that encompasses a wide range of progressive degenerative changes and affects all components of the cervical spine. DCS imposes very large social and economic burdens. However, its genetic basis remains elusive. Methods. Predicted whole-blood and skeletal muscle gene expression and genome-wide association study (GWAS) data from a DCS database were integrated, and functional summary-based imputation (FUSION) software was used on the integrated data. A transcriptome-wide association study (TWAS) was conducted using FUSION software to assess the association between predicted gene expression and DCS risk. The TWAS-identified genes were verified via comparison with differentially expressed genes (DEGs) in DCS RNA expression profiles in the Gene Expression Omnibus (GEO) (Accession Number: GSE153761). The Functional Mapping and Annotation (FUMA) tool for genome-wide association studies and Meta tools were used for gene functional enrichment and annotation analysis. Results. The TWAS detected 420 DCS genes with p < 0.05 in skeletal muscle, such as ribosomal protein S15A (RPS15A) (PTWAS = 0.001), and 110 genes in whole blood, such as selectin L (SELL) (PTWAS = 0.001). Comparison with the DCS RNA expression profile identified 12 common genes, including Apelin Receptor (APLNR) (PTWAS = 0.001, PDEG = 0.025). In total, 148 DCS-enriched Gene Ontology (GO) terms were identified, such as mast cell degranulation (GO:0043303); 15 DCS-enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were identified, such as the sphingolipid signalling pathway (ko04071). Nine terms, such as degradation of the extracellular matrix (R-HSA-1474228), were common to the TWAS enrichment results and the RNA expression profile. Conclusion. Our results identify putative susceptibility genes; these findings provide new ideas for exploration of the genetic mechanism of DCS development and new targets for preclinical intervention and clinical treatment.

Study purpose and background. Kinematic variables have been identified as potential biomarkers for low back pain patients; however, an in-depth comparison between chronic (n=22), acute (n=15), and healthy controls (n=136) has not been done. This retrospective data analysis compared intervertebral lumbar motion parameters, angular range of motion, translation, maximum disc height, motion share inequality (MSI) and variability (MSV), and laxity, between these groups. Methods and results. Kinematic parameters were determined using video tracking techniques utilising quantitative fluoroscopy (QF), during both weight-bearing and recumbent controlled sagittal bending tasks. Data was analysed for normality, and appropriate statistical tests were applied to determine differences between groups. There were no significant differences between the groups for age, height, weight and sex. Whilst few differences were found between acute and healthy groups, differences were shown between both chronic and healthy, and acute and chronic groups for all six parameters. Of particular note were examples of differences in the motion share parameters between the acute and chronic populations, with an increased MSI in the chronic group during recumbent flexion, and MSV during recumbent extension, and inversely an increase in MSV in the acute group during weight-bearing flexion. Conclusion. Analysis of intervertebral lumbar motion provides valuable insights into kinematic differences between chronic, acute, and healthy control populations. These findings suggest that there is variation between the groups which is knowledge that may benefit management strategies. Further exploration of the time varying data is warranted to explore how such differences may relate to the motion share inequalities and variability shown. Conflicts of Interest.

Purpose and background. Low back pain (LBP), a leading cause of chronic disability, is associated with high and disproportionate socioeconomic costs. Clinical assessment and triage via the NHS 111 service aims to reduce pressure on the urgent and emergency care system. Studies show that many attend the emergency department (ED) against advice, when they could be better managed elsewhere. The aim of this research was to explore how patients with LBP perceive and interact with NHS 111, and how this may have influenced their decision to attend ED. Methods and Results. This was a secondary analysis of a cross-sectional, qualitative dataset of 47 patients (26M:21F, aged 23–79 years) purposively sampled with LBP, who attended 1 of 4 EDs in the UK in 2021, (during the pandemic). The participants took part in online, semi-structured interviews, mean duration 45-minutes (range 23–156 minutes), within six weeks of their ED visit. The interviews were audio-recorded, transcribed verbatim and thematically analysed. Three key themes were identified: purpose, process and performance. The themes showed mixed understanding and low awareness of the purpose of NHS 111, despite its strong triage role. Long waits for call backs however, sometimes resulted in patients attending ED, along with previous negative perspectives and experiences. Conclusion. This research suggests enhanced visibility and knowledge of NHS 111 would increase its use by people with LBP. Further exploration comparing outcomes of callers to NHS 111 with those who seek care elsewhere, could help evaluate how NHS 111 can best help people with LBP and prevent unnecessary ED attendance.

Background. Trunk muscle activity and thoraco-lumbar kinematics have been shown to discriminate non-specific chronic low back pain (NSCLBP) subgroups from healthy controls. Thoracic spine kinematics and muscle activity whilst intuitively associated with NSCLBP, has received less attention and the possibility of intra-regional interactions remains an area for exploration. Purpose. Determine relationships between muscle activation and kinematics in active extension pattern (AEP) and flexion pattern (FP) subgroups and no-low back pain controls during a sagittal bending task. Methods. Fifty NSCLBP subjects (27 FP, 23 AEP) and 28 healthy controls underwent 3D motion analysis (Vicon™) and surface electromyography whilst bending to retrieve a pen from the floor. Mean sagittal angle for the upper and lower thoracic and lumbar regions (UTx, LTx, ULx, LLx) were compared with normalised mean amplitude electromyography of 4 bilateral trunk muscles. Pearson correlations were computed to assess relationships. Results. Significant relationships between lumbar multifidus and ULx/LLx were identified in AEP during bending and return (p<0.01). FP exhibited multiple significant interactions including between longissimus thoracis and lumbar multifidus and LLx/LTx (p<0.035); and external oblique activity and UTx/LTx (p<0.05) during bending and return (and LLx during bending). Correlations were moderate to strong (r= −0.812 to 0.664). Conclusion. Kinematic and trunk muscle activity measurements differentiated between NSCLBP sub-groups and controls, especially between LLx kinematics and lumbar multifidus activity. Contrasting muscle activation patterns between LLx and LTx regions in FP highlights the importance of regional thoracic measurements, and suggests likely compensation strategies. Replication during other tasks should be evaluated in future studies. No conflicts of interest. Funding provided by Versus Arthritis (Formerly Arthritis Research UK)

Background and aims. The Keele STarT Back approach is effective for stratifying patients with low back pain in primary care, but a similar approach has not been tested with a broader range of patients with musculoskeletal (MSK) pain. We report a feasibility and pilot trial examining the feasibility of a future main trial of a primary care based, risk-stratification (STarT MSK) approach for patients with back, neck, knee, shoulder or multi-site pain. Methods. A pragmatic, two-parallel arm, cluster randomised controlled trial (RCT) in 8 GP practices (4 stratified care involving use of the Keele STarT MSK tool and matched treatment options: 4 usual care). Following screening, adults with one of the five most common MSK pain presentations were invited to take part in data collection over 6 months. Feasibility outcomes included exploration of selection bias, recruitment and follow-up rates, clinician engagement with using the Keele STarT MSK tool and matching patients to treatments. Results. 524 participants (231-stratified care, 293-usual care) were recruited (target n=500) over 7 months (target 3 months), with 15-withdrawals (5-intervention, 10-controls). Minimal selection bias was identified between participants/non-participants, or trial arms. The pain-intensity follow-up rate was 88%. Clinicians used the STarT MSK tool in 41% of relevant consultations (judged as ‘partial success’) and adhered to recommended matched treatments in 69% of cases (judged as ‘success’). Conclusions. A future main RCT is feasible, with some amendments in the wording of the tool and the matched treatment options, to determine the clinical and cost-effectiveness of stratified care versus usual care for patients with MSK pain.

Aims

In this investigation, we administered oxidative stress to nucleus pulposus cells (NPCs), recognized DNA-damage-inducible transcript 4 (DDIT4) as a component in intervertebral disc degeneration (IVDD), and devised a hydrogel capable of conveying small interfering RNA (siRNA) to IVDD.

Purpose and Background:. To identify treatment effect modifiers within the STarT Back Trial which demonstrated prognostic stratified care was effective in comparison to standard care for patients with low back pain. Methods:. Secondary analysis of the STarT Back Trial using 688 patients with available 4-month follow-up data. Disability (baseline and 4 months) was assessed using the Roland Morris Disability Questionnaire (RMDQ) using continuous and dichotomized (>7) outcome scores. Potential treatment effect modifiers were evaluated with group x predictor interaction terms using linear and logistic regression models. Modifiers included: age, gender, education, socio-economic status (SES), employment status, work satisfaction, episode duration, general health (SF-12), number of pain medications, and treatment expectations. Results:. No significant treatment effect modifiers were identified using linear regression, however logistic regression analysis identified SES as a treatment modifier (interaction: OR = 0.65; 95% confidence interval = 0.42 to 0.98). Comparing those receiving stratified care versus best current care, the proportion of patients with poor 4 month outcome was similar for lower SES patients (35.4% vs. 37.2%), yet different for high SES patients (19.3% vs. 38.9%). No other treatment effect modifiers were identified; however exploratory analyses indicated trends for worse outcomes with increased age, patients taking ≥3 medications, those with lower education, and those with poor treatment expectations as potential treatment effect modifiers. Conclusion:. SES was identified as a treatment effect modifier in the STarT Back Trial with patients with lower SES not benefiting from stratified care. The explanations for this finding need further exploration

Aim:. Recent guidelines have been published by the Association of Neurophysiological Scientists / British Society for Clinical Neurophysiology (ANS/BSCN) regarding the use of intra-operative neurophysiological monitoring (IOM) during spinal deformity procedures. We present our unit's experience with IOM and the compliance with national guidelines. Method:. All patients undergoing intra-operative spinal cord monitoring during adult and paediatric spinal deformity surgery between Jan 2009 and Dec 2012 were prospectively followed. The use of somatosensory-evoked potentials (SSEPs) and motor-evoked potentials (MEPs) was recorded and monitoring outcomes were compared to post-operative clinical neurological outcomes. Compliance with the national ANS/BSCN guidelines was assessed. Results:. 333 patients were included in this study. IOM was successful in 312 patients (94%), with both MEPs and SSEPs obtained in 282 patients (85%). SEPs were achieved in 91% and MEPs in 87%. Aetiology was idiopathic in 199 cases, 53 neuromuscular, 28 degenerative, 16 congenital, 16 other. Nine patients had changes in IOM related to surgical activity; six had MEP changes only, three had MEPs and SSEPs changes. All but one of these changes returned to baseline following surgical action; the one remaining patient had a temporary postoperative neurological deficit. One patient had a post-operative single radiculopathy requiring surgical exploration, without change in initial IOM. Final IOM findings demonstrated a positive predictive value (PPV) of 1 and a negative predictive value (NPV) of 0.996. Discussion:. IOM is essential during spinal deformity surgery and, using MEPs, has a high PPV and NPV. Our unit meets guidelines for MEP use and frequently meets guidelines for SSEP use.

Purpose and background. Research on people's own experiences of living with sciatica is limited and this study aims to contribute to a better understanding of the impact of sciatica and its treatment. Methods. Longitudinal study based on in-depth interviews at baseline, six and twelve months follow-up. Thirty seven people were interviewed (15 men, 22 women) using a topic guide that allowed for detailed exploration of their story. All interviews were digitally recorded, fully transcribed, imported in the NVivo data management system and analysed thematically using the constant comparative method. Results. Leg pain was considered to be difficult to cope with as painkillers were limited in effectiveness, and many people were hampered in activities of daily living, work and leisure. The need for a clear diagnosis, prognosis, assessment of treatment options and potential outcomes was considered important. Comparing the patient's own story with the clinical explanation was seen to contribute to more effective therapeutic relationships. Conclusion. Acknowledging people's own accounts of sciatica is essential for achieving effective clinical processes and outcomes. The recognition of the specifically invasive nature of leg pain is crucial to a shared understanding of problems in daily life and in searching for solutions. Appropriate diagnosis and explanation and adequate pain relief seemed most important to the patients suffering with sciatica

We have assessed the efficacy of free nerve grafts in 90 cases of brachial plexus injury. Relatively good recovery of the elbow flexor and extensor muscles and of those of the shoulder girdle was found but recovery of the flexors and extensors of the forearm and of the intrinsic muscles of the hand was extremely poor. Poor results were found when spinal nerve roots seemed normal to the touch and appeared intact but had abnormal somatosensory evoked potentials or myelography. Recovery of the deltoid and infraspinatus muscles was better when injury had occurred to the circumflex and suprascapular nerves rather than to the plexus itself, perhaps because these nerves were explored in their entirety to determine the presence of multiple lesions. It is important to visualise the entire nerve thoroughly to assess the overall condition. Thorough exploration of the plexus and the use of intraoperative recording of somatosensory evoked potentials are essential

Aims

This study aimed to determine the relationship between pedicle-lengthening distance and bulge-canal volume ratio in cases of lumbar spinal stenosis, to provide a theoretical basis for the extent of lengthening in pedicle-lengthening osteotomies.

Diastematomyelia is a rare congenital abnormality of the spinal cord. This paper summarises more than 30 years’ experience of treating this condition. Data were collected retrospectively on 138 patients with diastematomyelia (34 males, 104 females) who were treated at our hospital from May 1978 to April 2010. A total of 106 patients had double dural tubes (type 1 diastematomyelia), and 32 patients had single dural tubes (type 2 diastematomyelia). Radiographs, CT myelography, and MRI showed characteristic kyphoscoliosis, widening of the interpedicle distance, and bony, cartilaginous, and fibrous septum. The incidences of symptoms including characteristic changes of the dorsal skin, neurological disorders, and congenital spinal or foot deformity were significantly higher in type 1 than in type 2. Surgery is more effective for patients with type 1 diastematomyelia; patients without surgery showed no improvement.

We describe three patients with pre-ganglionic (avulsion) injuries of the brachial plexus which caused a partial Brown-Séquard syndrome.

We reviewed 31 consecutive patients with Friedreich’s ataxia and scoliosis. There were 24 males and seven females with a mean age at presentation of 15.5 years (8.6 to 30.8) and a mean curve of 51° (13° to 140°). A total of 12 patients had thoracic curvatures, 11 had thoracolumbar and eight had double thoracic/lumbar. Two patients had long thoracolumbar collapsing scoliosis with pelvic obliquity and four had hyperkyphosis. Left-sided thoracic curves in nine patients (45%) and increased thoracic kyphosis differentiated these deformities from adolescent idiopathic scoliosis. There were 17 patients who underwent a posterior instrumented spinal fusion at mean age of 13.35 years, which achieved and maintained good correction of the deformity. Post-operative complications included one death due to cardiorespiratory failure, one revision to address nonunion and four patients with proximal junctional kyphosis who did not need extension of the fusion. There were no neurological complications and no wound infections. The rate of progression of the scoliosis in children kept under simple observation and those treated with bracing was less for lumbar curves during bracing and similar for thoracic curves. The scoliosis progressed in seven of nine children initially treated with a brace who later required surgery. Two patients presented after skeletal maturity with balanced curves not requiring correction. Three patients with severe deformities who would benefit from corrective surgery had significant cardiac co-morbidities.
