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. Methods and Results. A descriptive cross-sectional study was completed to explore and quantitatively measure the movement of ten physiotherapists during patient handling, over one working day, in a neurological setting. A wearable 3-dimensional motion analysis system, Xsens (Movella, Henderson, NV), was used to measure physiotherapist movement and postures in the ward setting during patient treatment sessions. The resulting joint angles were reported descriptively and compared against a frequently used ergonomic assessment tool, the Rapid Upper Limb Assessment (RULA). Physiotherapists adopted four main positions during patient handling tasks: 1) kneeling; 2) half-kneeling; 3) standing; and 4) sitting. Eight patient handling tasks were identified and described: 1) Lie-to-sit; 2) sit-to-lie; 3) sit-to-stand; facilitation of 4) upper limb; 5) lower limb; 6) trunk; and 7) standing treatments; and 8) walking facilitation. Kneeling and sitting positions demonstrated greater neck extension and greater lumbosacral flexion during treatments which scores highly with the RULA. Conclusion. This research identified that patient treatment tasks were more often performed in kneeling or sitting positions than standing. Current moving and handling guidance teaches moving and handling in a standing position; loading and stresses experienced by the physiotherapists may differ in sitting or kneeling positions.

Introduction. Lumbosacral transitional vertebrae (LSTV) are increasingly recognized as a common anatomical variant and is the most common congenital anomaly of the lumbosacral spine. Patients can have symptomatic LSTV, known as Bertolotti's Syndrome, where transitional anatomy can cause back, L5 distribution leg, hip, and groin pain. We propose an outline for diagnosis and treatment of Bertolotti's Syndrome. Methods. We retrospectively reviewed over 500 patients presenting to the primary author with low back, buttock, hip, groin and/or leg pain from April 2009 through April 2024. Patients with radiographic findings of an LSTV and clinical presentation underwent diagnostic injections to confirm diagnosis of Bertolotti's syndrome. Treatment was determined based on patient's LSTV classification. 157 patients with confirmed Bertolotti's syndrome underwent surgical treatment. Results. Over 500 patients presented with an appropriate clinical presentation and radiographic findings of an LSTV. Diagnostic injections were targeted into the transitional anatomy confirming the LSTV as the primary pain generator to make the diagnosis of Bertolotti's syndrome. The decision in the type of surgical intervention, resection or fusion, was made based on patient's LSTV anatomy. 157 patients with confirmed Bertolotti's Syndrome underwent surgical treatment (121 fusions (77%), 36 resections (23%)). The classification system and surgical outcomes, in part, have been previously published in World Neurosurgery. Conclusion. We have outlined the best practice of diagnosis and treatment selection for Bertolotti's syndrome. We have shown significant improvement in outcomes based on this method. We hope to aid in both patient education and provide an outline on how clinicians can become knowledgeable on Bertolotti's syndrome. Conflicts of interest. No conflicts of interest.

Introduction and Objective. Almost 60% of the population can expect to experience low back pain (LBP) during their life. Several radiological tools are used to investigate LBP. However, adequate evidence is unavailable to support the use of single photon emission computer tomography (SPECT) in patients with LBP. The objective of this study is to assess the role and efficiency of SPECT in evaluation and management of patients with LBP. Method. Ninety-two patients with LBP were examined and assessed. All the patients received a magnetic resonance imaging (MRI) scan and were referred for a SPECT. We interpreted the modic and degenerative changes found on the MRI and compared it with SPECT tracer uptake. SPECT was used to identify the pain generator and then a surgical plan was made. Data was analyzed for pain improvement in those who underwent surgical treatment to establish the accuracy of CT SPECT in identification of primary pain generator. Results. A total of 184 patients were included in the study who underwent diagnostic CT-SPECT between January 2013 and December 2019. One hundred of them were females and Eighty four males; the mean age was 47.6 years. 111 patients underwent surgery in the form of interbody fusion or posterolateral fusion. 16 patients positive tracer uptake was at asymptomatic level or unrelated. In 3 patients SPECT identified screw sites as pain generator and in all 3 patients screws were removed with good pain relief. Overall axial pain as measured with Numeric rating scale was preoperatively 9.13 ± 0.7 and improved to 4.54 ± 2.3 at 6 months postoperative follow up. MRI changes have been analyzed and correlation studied with relation to SPECT findings. Conclusion. Due to its high precision and sensitivity compared to other radiological modalities, SPECT demonstrated the ability to aid in clinical diagnosis. CT SPECT reveals information that becomes vital in deciding further management. In this study, we exemplified that SPECT scan can give indication for pain generator in axial spine pain and aid in surgical intervention

Aims. To develop and internally validate a preoperative clinical prediction model for acute adjacent vertebral fracture (AVF) after vertebral augmentation to support preoperative decision-making, named the after vertebral augmentation (AVA) score. Methods. In this prognostic study, a multicentre, retrospective single-level vertebral augmentation cohort of 377 patients from six Japanese hospitals was used to derive an AVF prediction model. Backward stepwise selection (p < 0.05) was used to select preoperative clinical and imaging predictors for acute AVF after vertebral augmentation for up to one month, from 14 predictors. We assigned a score to each selected variable based on the regression coefficient and developed the AVA scoring system. We evaluated sensitivity and specificity for each cut-off, area under the curve (AUC), and calibration as diagnostic performance. Internal validation was conducted using bootstrapping to correct the optimism. Results. Of the 377 patients used for model derivation, 58 (15%) had an acute AVF postoperatively. The following preoperative measures on multivariable analysis were summarized in the five-point AVA score: intravertebral instability (≥ 5 mm), focal kyphosis (≥ 10°), duration of symptoms (≥ 30 days), intravertebral cleft, and previous history of vertebral fracture. Internal validation showed a mean optimism of 0.019 with a corrected AUC of 0.77. A cut-off of ≤ one point was chosen to classify a low risk of AVF, for which only four of 137 patients (3%) had AVF with 92.5% sensitivity and 45.6% specificity. A cut-off of ≥ four points was chosen to classify a high risk of AVF, for which 22 of 38 (58%) had AVF with 41.5% sensitivity and 94.5% specificity. Conclusion. In this study, the AVA score was found to be a simple preoperative method for the identification of patients at low and high risk of postoperative acute AVF. This model could be applied to individual patients and could aid in the decision-making before vertebral augmentation. Cite this article: Bone Joint J 2022;104-B(1):97–102

Aims. The aim of this study was to identify the risk factors for adverse events following the surgical correction of cervical spinal deformities in adults. Methods. We identified adult patients who underwent corrective cervical spinal surgery between 1 January 2007 and 31 December 2015 from the MarketScan database. The baseline comorbidities and characteristics of the operation were recorded. Adverse events were defined as the development of a complication, an unanticipated deleterious postoperative event, or further surgery. Patients aged < 18 years and those with a previous history of tumour or trauma were excluded from the study. Results. A total of 13,549 adults in the database underwent primary corrective surgery for a cervical spinal deformity during the study period. A total of 3,785 (27.9%) had a complication within 90 days of the procedure, and 3,893 (28.7%) required further surgery within two years. In multivariate analysis, male sex (odds ratio (OR) 0.90 (95% confidence interval (CI) 0.8 to 0.9); p = 0.019) and a posterior approach (compared with a combined surgical approach, OR 0.66 (95% CI 0.5 to 0.8); p < 0.001) significantly decreased the risk of complications. Osteoporosis (OR 1.41 (95% CI 1.3 to 1.6); p < 0.001), dyspnoea (OR 1.48 (95% CI 1.3 to 1.6); p < 0.001), cerebrovascular accident (OR 1.81 (95% CI 1.6 to 2.0); p < 0.001), a posterior approach (compared with an anterior approach, OR 1.23 (95% CI 1.1 to 1.4); p < 0.001), and the use of bone morphogenic protein (BMP) (OR 1.22 (95% CI 1.1 to 1.4); p = 0.003) significantly increased the risks of 90-day complications. In multivariate regression analysis, preoperative dyspnoea (OR 1.50 (95% CI 1.3 to 1.7); p < 0.001), a posterior approach (compared with an anterior approach, OR 2.80 (95% CI 2.4 to 3.2; p < 0.001), and postoperative dysphagia (OR 2.50 (95% CI 1.8 to 3.4); p < 0.001) were associated with a significantly increased risk of further surgery two years postoperatively. A posterior approach (compared with a combined approach, OR 0.32 (95% CI 0.3 to 0.4); p < 0.001), the use of BMP (OR 0.48 (95% CI 0.4 to 0.5); p < 0.001) were associated with a significantly decreased risk of further surgery at this time. Conclusion. The surgical approach and intraoperative use of BMP strongly influence the risk of further surgery, whereas the comorbidity burden and the characteristics of the operation influence the rates of early complications in adult patients undergoing corrective cervical spinal surgery. These data may aid surgeons in patient selection and surgical planning. Cite this article: Bone Joint J 2021;103-B(4):734–738

Introduction. Treatment of spinal metastatic disease has evolved with the advent of advanced interventional, surgical and radiation techniques. Spinal Oligometastatic disease is a low volume disease state where en bloc resection of the tumour, based on oncological principles, can achieve maximum local control (MLC). Hybrid therapy incorporating Separation surgery (>2mm clearance of the thecal sac) and Stereotactic Ablative Radiotherapy (SABR) offer an alternative approach to achieving MLC. Hybrid therapy is also a viable option in patients eligible for SBRT who have failed conventional radiation therapy. En-bloc surgery may be a suitable option for those patients who are ineligible for or have failed SBRT. A multidisciplinary approach is particularly important in the decision-making process for these patients. Metal free instrumentation is aiding the optimization of these surgeries. The authors present a supra-regional centre's experience in managing spinal oligometastases. Methods. Retrospective review of oligometastatic spinal disease at a supra-regional centre between 2017 and 2021. Demographics, operative course, complications and Instrument type are examined. Results. Demographics: 24 patients with mean age 53.8y (range 12–77), 44% (40y–59y), 40% (60y–69y); 51% Male. Histology: Breast, Renal and Sarcoma accounted for 16.7% each; Thyroid, Prostate and Chordoma accounted for 8.3% each. Primary disease 7%, Synchronous 15%, Metachronous 78%. Instrumentation: Carbon-fibre (85%), TiAl (11%), Non-Instrumented (3%). Separation Surgery (70%), En-bloc resection/Tomita surgery (30%); SABR/Proton Beam Planned: 70%. Average length of hospital stays 19.1 days; twenty patients required intensive care admission for an average 2.7 days. 30 Day Mortality 8.3% (n=2: COVID-19 during admission and ventriculitis post discharge), 1y Mortality – 16.7%, 3y Mortality – 25%; Synchronous Mortality 75% (n=3) at 3 years. 30 Day infection rate 3%; 1y infection rate 7%. 1 Non-instrumented case developed proximal junctional failure post proton beam therapy and required a vascularised fibular strut graft. 2-year Revision for Local Recurrence 5% (Revision at 23 months). Conclusion. There are very few case series of oligometastatic spinal disease due to the relatively new concept of adjuvant SABR and its limited availability. Solid tumours pre-dominated the histology in our series with metachronous disease being the most commonly operated disease state. 92% of cases were eligible for SABR. The majority (85%) of cases were performed with Carbon-fibre instrumentation and has been shown to be safe with no mechanical failures in this series. Infection rates are in keeping with patients requiring radical radiotherapy with 3% early and 7% late. 30-day mortality was 8.3%, 1y=16.7% and 25% at last follow up. Mortality, as expected, is highest within the synchronous disease group and should be operated on sparingly. With the current management strategy, there was no local recurrence at 1 year and excellent local recurrence rate at 2 years (5%). Although radical en bloc surgery carries significant morbidity, it should be considered in selective cases to achieve MLC. All Oligometastatic cases deserve extra consideration and specialist MDT as not all are suitable for SABR. Multimodal Hybrid therapy, incorporating less invasive surgical techniques and SABR, represents a paradigm shift in achieving MLC in oligometastatic spinal disease

Aims. The British Spine Registry (BSR) was introduced in May 2012 to be used as a web-based database for spinal surgeries carried out across the UK. Use of this database has been encouraged but not compulsory, which has led to a variable level of engagement in the UK. In 2019 NHS England and NHS Improvement introduced a new Best Practice Tariff (BPT) to encourage input of spinal surgical data on the BSR. The aim of our study was to assess the impact of the spinal BPT on compliance with the recording of surgical data on the BSR. Methods. A retrospective review of data was performed at a tertiary spinal centre between 2018 to 2020. Data were collated from electronic patient records, theatre operating lists, and trust-specific BSR data. Information from the BSR included operative procedures (mandatory), patient consent, email addresses, and demographic details. We also identified Healthcare Resource Groups (HRGs) which qualified for BPT. Results. A total of 3,587 patients were included in our study. Of these, 1,684 patients were eligible for BPT. Between 2018 and 2019 269/974 (28%) records were complete on the BSR for those that would be eligible for BPT. Following introduction of BPT in 2019, 671/710 (95%) records were complete having filled in the mandatory data (p < 0.001). Patient consent to data collection also improved from 62% to 93%. Email details were present in 43% of patients compared with 68% following BPT introduction. Conclusion. Our study found that following the introduction of a BPT, there was a statistically significant improvement in BSR record completion compliance in our unit. The BPT offers a financial incentive which can help generate further income for trusts. National data input into the BSR is important to assess patient outcome following spinal surgery. The BSR can also aid future research in spinal surgery. Cite this article: Bone Jt Open 2021;2-3:198–201

Purpose. To establish if the subjective features of both bilateral leg pain and sexual dysfunction are presenting features in cauda equina syndrome (CES). Background. There appears to be conflicting expert opinion ‘red flag’ symptoms in the context of CES with many experts basing clinical decisions on the objective clinical findings only. Bilateral radiculopathy has been suggested as a possible sign of suspected CES, although a consensus statement by BASS and SBNS makes no reference to either this or sexual dysfunction. However, bilateral leg pain is included in the NICE clinical knowledge summary and sexual dysfunction is highlighted within CES guidance by the American Association of Neurological Surgeons. Methods. The clinical documentation of patients undergoing urgent magnetic resonance imaging (MR) due to clinical suspicion of cauda equina syndrome (CES) was reviewed over 12 months. Patients questioned regarding sexual function were included in this retrospective analysis (n=179), along with those with bilateral leg pain (n=294). Patients with confirmed cauda equina compression (CES +ve) were compared to those without (CES -ve). A logistic regression was applied to find the odds ratio. Results. In CES +ve 37.5% had sexual dysfunction, 48% had bilateral leg pain. CES –ve 14% had sexual dysfunction, 27% bilateral leg pain. Both significant to p=0.015 with an odds ratio of 3.6 and 2.5 respectively. Conclusions. Both sexual dysfunction and bilateral leg pain do appear to be ‘red flags’ for CES and should therefore be asked in the ED to aid clinical reasoning when suspecting this diagnosis.

Introduction. Intervertebral disc degeneration (IVDD) associated with low back pain is a major contributor to global disability. Current treatments are poorly efficient in the long-term resulting in medical complications. Therefore, minimally invasive injectable therapies are required to repopulate damaged tissues and aid regeneration. Among injectable biomaterials, self-assembling peptide hydrogels (SAPHs) represent potential candidates as 3D cell carriers. Moreover, the advent of graphene-related materials has opened the route for the fabrication of graphene-containing hydrogel nanocomposites to direct cellular fate. Here, we incorporated graphene oxide (GO) within a SAPH to develop a biocompatible and injectable hydrogel to be used as cell carrier to treat IVDD. Methods and results. Hydrogel morphology and mechanical properties have been investigated showing high mechanical properties (G'=12kPa) comparable with human native nucleus pulposus (NP) tissue (G'=10kPa), along with ease of handling and injectability in dry and body fluid conditions. Hydrogel nanocomposites resulted biocompatible for the encapsulation of bovine NP cells, showing higher viability (>80%) and metabolic activity in 3D cell culture over 7 days, compared to GO-free hydrogels. Moreover, GO has demonstrated to bind TGF-β3 biomolecules with high efficiency, suggesting the use of GO as local reservoir of growth factors within the injected hydrogel to promote extracellular matrix deposition and tissue repair. Conclusions. Our results show that incorporation of GO within the SAPH improves cell viability and metabolic activity. Furthermore, its tissue-mimicking mechanical properties and chemical tunability make it a promising candidate as injectable carrier of NP cells for the treatment of IVDD.

Aims

The aim of this study was to investigate the incidence and characteristics of instrumentation failure (IF) after total en bloc spondylectomy (TES), and to analyze risk factors for IF.

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.

Aims

Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age.

Background. Improving primary care management of musculoskeletal (MSK) pain is a priority. A pilot cluster RCT tested prognostic stratified care for patients with common MSK pain presentations, including low back pain, in 8 UK general practices (4 stratified care; 4 usual care) with 524 patients. GPs in stratified care practices were asked to use i) the Keele STarT MSK tool for risk-stratification and ii) matched treatment options for patients at low-, medium- and high-risk of persistent pain. A linked qualitative process evaluation explored patients' and GPs' views and experiences of stratified care. Methods. Individual ‘stimulated-recall’ interviews with patients and GPs in the stratified care arm (n=10 patients; 10 GPs), prompted by consultation-recordings. Data were analysed thematically and mapped onto the COM-B behaviour change model; exploring the Opportunity, Capability and Motivation GPs and patients had to engage with stratified care. Results. Patients reported positive views that stratified care enabled a more ‘structured’ consultation. GPs identified difficulties integrating the STarT MSK tool in their consultation timeframe (Opportunity), but found this easier as it became more familiar. Both groups saw the tool as having added-value, but identified ‘cumbersome’ items which made it more difficult to use (Capability). GPs reported the matched treatment options aided their clinical decision-making, identified several that were not available to them (e.g. pain-management clinics) and suggested additional options (e.g. GP-management of psychosocial issues (Motivation). Conclusion. Changes to the STarT MSK tool and matched treatment options, targeting the COM-B model constructs, were identified and have been implemented in the current main trial.

Aims

Developmental cervical spinal stenosis (DcSS) is a well-known predisposing factor for degenerative cervical myelopathy (DCM) but there is a lack of consensus on its definition. This study aims to define DcSS based on MRI, and its multilevel characteristics, to assess the prevalence of DcSS in the general population, and to evaluate the presence of DcSS in the prediction of developing DCM.

Background and Purpose. Chronic low back pain (CLBP) can be constant or episodic. Fluctuations are common. We present two different pictures of the CLBP experience; timelines illustrating back pain over time and ‘web diagrams’ showing a snapshot of a phase in time. Methods. Semi structured interviews from 34 participants from the UK BeST trial included timelines drawn collaboratively by the researcher and participant. Symptoms, events, treatment and consultations were arranged chronologically along a timeline. Initial thematic analysis on 63 interviews gave bio-psychosocial themes that were spoken about in an integrated way. Further analysis explored these interactions between themes. Interactions were classified as; helpful to recovery, unhelpful or mixed. Web diagrams were drawn for each interview and classified as Dense- mostly unhelpful interactions, Open – a combination of helpful and unhelpful interactions and Sparse – mostly helpful interactions. Results. Timelines were easy to compile and helped participants to describe their CLBP history. Timelines elicited rich data and promoted comparisons within and between cases aiding reflexivity. Web diagrams graphically illustrated the complexities of a person's LBP experience at that time. Dense webs showed a complex ‘locked in’ presentation. Open webs showed some helpful and less unhelpful interactions suggesting change may be easier to facilitate and sparse webs suggested that the participant was managing their own recovery. Conclusions. Timelines are a useful tool to assist history taking and facilitate discussion. Web diagrams illustrate the complex presentations often found in CLBP. Identifying patterns of unhelpful as well as helpful interactions between bio psychosocial factors may aid clinicians in their treatment approaches. Conflicts of interest: No conflicts of interest.

Aims

Psychoeducative prehabilitation to optimize surgical outcomes is relatively novel in spinal fusion surgery and, like most rehabilitation treatments, they are rarely well specified. Spinal fusion patients experience anxieties perioperatively about pain and immobility, which might prolong hospital length of stay (LOS). The aim of this prospective cohort study was to determine if a Preoperative Spinal Education (POSE) programme, specified using the Rehabilitation Treatment Specification System (RTSS) and designed to normalize expectations and reduce anxieties, was safe and reduced LOS.

Background. We have reported an injectable L-pNIPAM-co-DMAc hydrogel with hydroxyaptite nanoparticles (HAPna) which promotes mesenchymal stem cell (MSC) differentiation to bone cells without the need for growth factors. This hydrogel could potentially be used as an osteogenic and osteoconductive bone filler of spinal cages to improve vertebral body fusion. Here we investigated the biocompatibility and efficacy of the hydrogel in vivo using a proof of concept femur defect model. Methods. Rat sub-cut analysis was performed to investigate safety in vivo. A rat femur defect model was performed to evaluate efficacy. Four groups were investigated: sham operated controls; acellular L-pNIPAM-co-DMAc hydrogel; acellular L-pNIPAM-co-DMAc hydrogel with HAPna; L-pNIPAM-co-DMAc hydrogel with rat MSCs and HAPna. Following 4 weeks, defect site and organs were histologically examined to determine integration, repair and inflammatory response, as well as Micro-CT to assess mineralisation. Results. No inflammatory reactions or toxicity were seen in any animal. Enhanced bone healing was observed in aged exbreeder female rats where hydrogel was injected with increased deposition of collagen type I. Integration of the hydrogel with surrounding bone was observed without the need for delivered MSCs; native cell infiltration was also seen and bone formation was observed within all hydrogel systems investigated. Conclusion. This novel hydrogel is biocompatible, facilitates migration of cells, promotes increased bone formation and integrates with surrounding bone. This system could be injected to fill spaces within and surrounding spinal cages to aid in cage fixation and spinal fusion without the need for harvesting of bone autografts, thus reducing operative risk and surgical cost.

Aim. To identify a means to reduce the duration and radiation dose coupled with fluoroscopic guided nerve root blocks (NRB). Method. Consecutive prospective two cohort comparative study. A similar method performed during CT guided NRBs was employed to guide needle placement for transforaminal nerve root injections with the aid of static MR images and fluoroscopy. Axial MR images at the level of the target nerve root were used. An angle of inclination of 60 degrees was created from the nerve root to the skin of the back, the apex of this to represent the site of needle introduction. Triangulation on the MRI enabled the lateral entry point to be determined. The transforaminal injections were then performed with the simple expedient of a skin marker line at the appropriate lateral distance from the midline for needle entry. The radiation dose and fluoroscopic time as measured by the image intensifier were recorded. This method was performed for 20 patients and compared to the same parameters for 23 previous patients in whom the transforaminal injections were performed without such a technique. Results. 20 patients in the navigated arm (group 1) and 23 in the non-navigated (group 2). Average fluoroscopic time (seconds) was 17.7 seconds (range 8-40) for group 1 and 16.4 seconds (range 6-45) for group 2 (P value 0.625). Radiation dose measured was 79.76 cgycm. 2. (range 8-212) for group 1 and 63.05 cgycm. 2. (range 8-260) for group 2 (P value 0.247). Conclusion. This method of navigating nerve root blocks via fluoroscopy did not appear to reduce the duration of the procedure or radiation dose involved on objective data. Subjectively it was found to be a useful training aid for triangulation for those new to the technique but the available objective evidence was not obtained

Aims

The aim of this study was to assess the ability of morphological spinal parameters to predict the outcome of bracing in patients with adolescent idiopathic scoliosis (AIS) and to establish a novel supine correction index (SCI) for guiding bracing treatment.

Purpose of study. To evaluate implementation of the Back Skills Training (BeST) programme in clinical practice within the National Health Service (NHS). Background. The BeST programme is a group Cognitive Behavioural Approach (CBA) for people with persistent (≥6 weeks) low back pain (LBP). This intervention has been shown to be clinically and cost-effective in a large pragmatic trial. To aid implementation of the BeST programme, an online training intervention (iBeST) was developed. Methods. iBest was promoted through marketing activities (e.g. conferences, social media, evidence briefs) prior to release and launched in March 2016 for NHS health care professionals. Impact of iBeST is being evaluated by measuring number enrolled, course completion, implementation intention, clinical delivery, perceived competence, attitudes/beliefs towards LBP, knowledge and satisfaction. Data is collected at pre and post-training, 4 months and 12 months after course completion. A service evaluation is also being conducted to measure clinical impact. Patients taking part in the BeST programme as part of routine treatment complete questionnaires at baseline, post-treatment, 3 months and 12 months after the programme to assess pain, disability, recovery, satisfaction and usefulness of BeST. Results. 881 clinicians have enrolled on iBeST and 260 have completed training (target: 250). 28 NHS sites are delivering the BeST programme. 385 and 290 participants have provided baseline and post treatment data respectively (target: 400). Data collection is ongoing. Conclusion. Implementation is challenging but iBeST has been well received by NHS clinicians and we plan to report further results of the impact and service evaluation.
