International Framework for Red Flags for Potential Serious Spinal Pathologies

Comparison of erector spinae and gluteus medius muscle thickness and activation in individuals with and without low back pain

BACKGROUND

Dysfunctional patterns of the erector spinae (ES) and gluteus medius (GM) muscles often accompany episodes of low back pain (LBP). Rehabilitative ultrasound imaging (RUSI) has been used to measure ES and GM muscle thickness, however such measurements have not been compared in individuals with and without LBP.

OBJECTIVES

To compare ES and GM muscle thickness and change in thickness utilizing RUSI in individuals with and without LBP.

DESIGN

Cross-sectional comparison.

METHODS

A volunteer sample of 60 adults with (n = 30) and without (n = 30) LBP was examined. Thickness measurements of the ES and GM at rest and during contraction were obtained by using RUSI during a single session. Statistical comparison was performed using ANCOVA. The demographic variable age was used as a covariate in the primary comparative analysis.

RESULTS

Mean difference for age between groups was 5.4 years (95% CI: 1.85, 8.94, p = 0.004). Average ODI score was 32.33±6.58 and pain level of 5.39±0.73 over the last 24 h in the symptomatic group. There was a statistically significant difference in the percent thickness change in both the ES, mean difference = -3.46 (95% CI: -6.71, -0.21, p = 0.039) and GM, mean difference = -1.93 (95% CI: -3.85, -0.01, p = 0.049) muscles between groups.

CONCLUSIONS

Individuals with LBP may have reduced percent thickness change of the ES and GM muscles when compared to asymptomatic individuals.

Effects of monopolar pulsed-capacitive dielectric radiofrequency diathermy in patients with chronic low back pain: a randomised clinical trial

Monopolar capacitive diathermy is a physiotherapy technique that uses high-frequency currents to generate heat in deep tissues. This heat can have several therapeutic effects, especially in the treatment of chronic low back pain (CLBP), however, until now there is little evidence of this type of diathermy. The purpose was to evaluate the efficacy of a pulsed monopolar dielectric radiofrequency diathermy (PRF)-capacitive type versus simulated treatment on symptomatology of patients with CLBP. A single-blind randomised controlled trial was conducted. Sixty patients with CLBP were randomly assigned to a PRF-capacitive or a simulated treatment group. All participants received 3 sessions per week for 3 weeks. Disability, pain intensity, movement phobia, lumbar anteflexion, quality of life, and sleep quality were assessed at baseline, after treatment, and at two months. The application of 9 sessions of PRF-capacitive showed significant improvements compared to simulated therapy during the entire follow-up for disability (F = 26.99, p < 0.001), pain intensity (F = 0.550, p < 0.001), the quality of life components of physical function (F = 0.780, p < 0.001), social function (F = 0.780, p < 0.001) and mental health (F = 0.858, p = 0.003) and for sleep duration (F = 0.863, p = 0.004).

Embedded motivational interviewing combined with a smartphone application to increase physical activity in people with sub-acute low back pain: a cluster randomised controlled trial

BACKGROUND

Moderately vigorous physical activity (PA) may be beneficial for people with sub-acute low back pain (LBP), but may initially be painful for patients and challenging for physical therapists to facilitate.

OBJECTIVES

This study investigated motivational interviewing (MI) delivered by physical therapists and a smartphone app for increasing PA in people with LBP.

METHODS

A mixed methods cluster randomised controlled trial involving 46 adults with LBP in Melbourne, Australia. Participants attended weekly 30-min physical therapy consultations for 6 weeks. Experimental group physical therapists were taught to embed MI into consultations and patients were provided with a self-directed app. The primary outcome was accelerometer-derived moderately vigorous PA. Secondary outcomes were LBP disability (Oswestry Disability Index), functional capacity (Patient Specific Functional Scale), and self-efficacy (Pain Self-Efficacy Questionnaire). Between-group differences were analysed by ANCOVA post-intervention.

RESULTS

There was no statistically significant difference between the experimental group and control group for PA. Between-group differences in LBP disability (MD= 19.4 units, 95% CI: 8.5, 30.3), functional capacity (primary MD= -4.1 units, 95% CI: -6.9, -1.3; average MD= -3.1, 95% CI: -4.9, -1.2) and self-efficacy (MD -11.3 units, 95%CI -20.2, -2.5) favoured the control group with small to moderate effect sizes. There were low levels of overall engagement with the app.

CONCLUSION

The embedded MI intervention was no more beneficial than physical therapy alone for PA and was associated with poorer LBP disability, function, and self-efficacy. The effectiveness of embedding MI and a smartphone app into usual care for LBP was not supported.

A clinical audit of the Emergency Department: Doctors' opinions on the diagnosis and management of cervical spine radiculopathy

OBJECTIVE

A clinical audit was carried out on the opinions of doctors working in the Emergency Department (ED) of a large urban hospital regarding the diagnosis and management of cervical spine radiculopathy (CSR). Using international guidelines and current research, it aimed to determine if patients attending this ED were diagnosed and managed in line with best practice, and to identify any discrepancies or areas for improvement in relation to this.

METHOD

Doctors working in this ED were sent an online questionnaire and descriptive analysis was performed on the results to ascertain how they diagnose and manage patients who present with symptoms of CSR. It covered; presentation and definitions of CSR, identification of red flags, clinical tests used, diagnostic test criteria, appropriate management, education and advice given, and the criteria for further management. Additionally, it looked at their opinion on the services' needs.

RESULTS

Most agreed that CSR will improve within 4 weeks with non-operative management; however, there was a lack of consensus regarding the most affected nerve root, differential diagnosis and appropriate diagnostic tests. Opinions aligned regarding the identification of red flags and early management, especially with widespread neurological deficits. However, the management of ongoing pain or new neurological signs, differed between clinicians. Most participants strongly agreed that access to MRIs affected referrals within an ED episode.

CONCLUSION

Overall, the opinions matched recommended guidelines; however, some gaps in knowledge and differing management approaches were identified, indicating the need for ongoing education and standardisation of management.

Identifying and navigating suspected serious pathologies: New-graduate physiotherapists' perspectives and developmental needs

BACKGROUND

Physiotherapists in Australia play a vital first-contact role in identifying suspected serious pathologies and navigating their management pathways. Current literature highlights challenges faced by physiotherapists including implications of ineffective identification and management of suspected serious pathologies, yet the perspectives of new-graduate physiotherapists related to this area of practice remain unknown.

OBJECTIVE

The aim of this study was to explore new-graduate physiotherapists' perspectives and developmental needs related to identifying suspected serious pathologies and navigating their management pathways in patients with musculoskeletal complaints.

DESIGN

and Method: A qualitative study using a reflexive thematic analytical approach was undertaken. Eighteen semi-structured interviews were conducted. Thematic analysis was utilized on the interview data.

RESULTS

Four key themes were generated: (1) Physiotherapists as advocates; (2) Navigating uncertainties and complexities; (3) Safe and accessible workplace support builds confidence; and (4) Importance of direct learning opportunities.

CONCLUSION

New-graduate physiotherapists recognize their imperative role as first-contact practitioners in identifying and navigating suspected serious pathologies yet also experience significant uncertainties. The findings highlight key developmental needs, including supportive workplaces, established referral frameworks and direct learning opportunities during pre-professional training.

Preoperative motor weakness and the impact on patient reported outcomes in lateral lumbar interbody fusion

This study measures the impact of preoperative motor weakness (MW) on Patient-Reported Outcome Measures (PROMs) in lateral lumbar interbody fusion (LLIF) patients. Retrospectively-sourced data from a prospectively-maintained, single-surgeon database created two cohorts of LLIF patients: patients with/without documented MW. Demographics/perioperative characteristics/PROMs were collected preoperatively and at six-weeks/final follow-up (FF). Studied outcomes were Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), 12-Item Short Form (SF-12) Physical/Mental Component Score (PCS/MCS), Patient Health Questionnaire (PHQ-9), Visual Analog Scale Back/Leg Pain (VAS-BP/LP), and Oswestry Disability Index (ODI). Multivariable linear/logistic regression calculated/compared intercohort minimum clinically important difference (MCID). Mean postoperative follow-up time was 11.5 ± 7.52 months. In total, 214 LLIF patients from December 2010 to May 2023 were included, with 149 having documented MW. In Table 1, self-reported gender was significant between cohorts (p < 0.025). Other significant demographic characteristics were smoker status (p < 0.002), diabetes (p < 0.016), and CCI score (p < 0.011). Table 2 shows notably significant perioperative characteristics: spinal pathology (degenerative spondylolisthesis/foraminal stenosis/herniated nucleus pulposus) (p < 0.005, all), estimated blood loss/length of stay/postoperative day (POD)-zero narcotic consumption (p < 0.001, all). Table 3 outcomes/MCID achievement percentages demonstrated insignificant intercohort differences besides a weakly significant FF ODI score (p < 0.036). MW, a frequently reported symptom in spine surgery, is poorly studied in LLIF patients. Thus, this study evaluates MW impact on PROMs and notes no significant differences. However, one exception regarding FF disability scores was recorded. MW did not affect MCID achievement for our patient population. Therefore, the preliminary findings suggest preoperative MW imparts minimal influence on PROMs/MCID in LLIF patients.

Physiotherapists' awareness and use of red flags for the assessment of low back pain in Saudi Arabia

BACKGROUND

Physiotherapists must identify potential red flags that may impede recovery and function in individuals with low back pain (LBP) or put them at risk.

OBJECTIVES

This study aimed to (1) investigate physiotherapists' awareness and use of red flags for individuals with LBP in Saudi Arabia and (2) identify factors associated with their awareness and use of LBP red flags.

METHODS

This cross-sectional study collected data using an anonymous online questionnaire (February-July 2023). It included physiotherapists working in private/public hospitals in Saudi Arabia. The questionnaire asked about the participants' characteristics, their awareness of LBP red flags, and their use of red flags for LBP assessment.

RESULTS

A total of 643 participating physiotherapists (26.2 ± 3.8 years), 63.8% of whom were females, completed the survey. Most participants (94.4%) had adequate awareness of LBP red flags, and more than half (61%) had good utilization of red flags when assessing individuals with LBP. There was a positive correlation between the physiotherapists' awareness and use of LBP red flags.

CONCLUSION

The majority of the participating physiotherapists in Saudi Arabia were aware of LBP red flags, and many reported to have good use of red flags in clinical practice when assessing and managing individuals with LBP.

Empowering patients with persistent pain: The potential of cognitive functional therapy in interdisciplinary care: A single-case experimental design

INTRODUCTION AND PURPOSE

Persistent musculoskeletal pain (PMP) is multifactorial and causes both societal and financial burdens. Integration of multifactorial management in patients with PMP remains challenging. A single-case experimental design was performed on three patients suffering from high impact PMP (lumbar spine, shoulder and knee) to i) assess the potential for Cognitive Functional Therapy (CFT) in interdisciplinary care, ii) describe in detail the clinical journey patients experienced during the intervention, and iii) evaluate the changes and associations in relation to the outcome measures of pain, disability, maladaptive movement behavior, subjective overall improvement, health related quality of life and work status. These were monitored over one year, at the end of each of the six intervention modules.

RESULTS

After introducing the intervention systematic changes were seen, with medium to large changes (Non-overlap of All Pairs 0.67-1) for all outcome measures. Associations between changes of the outcome measures were large (r ≥ 0.50) and changes occurred concurrently. Minimally clinically important difference thresholds were exceeded for all outcome measures and two patients achieved relevant improvements related to work reintegration.

DISCUSSION

The positive results of this study are comparable with recent CFT studies. However, the difference regarding the number of sessions and duration of the intervention is evident. The length of the intervention in this study seemed to enable continuous significant improvements up until 12 months post onset and follow-up.

CONCLUSION

CFT in interdisciplinary care was effective for all measures. The detailed descriptions of the clinical processes aim to improve clinical care.

Exploring fascial properties in patients with depression and chronic neck pain: An observational study

BACKGROUND

Depressive disorder and chronic pain are prevalent conditions that often co-occur. The myofascial fascial continuum has been hypothesized to contribute to both conditions. However, limited research exists on the specific association between fascial properties and chronic pain and depression.

OBJECTIVE

This study aims to investigate the properties of the deep fascia of the M. trapezius and their relationship with depression, chronic neck pain, and cervical spine mobility.

METHOD

This study compared fascial properties between two groups: individuals with depression and chronic neck pain, and healthy individuals. Fascial thickness, elasticity, and stiffness were measured as primary outcomes using standardized techniques such as ultrasound imaging and compliance meter. Statistical analyses were conducted to identify potential differences and correlations in fascial properties between the two groups.

RESULT

Significant differences emerge in stiffness, tone, and fascia thickness in the deep fascia, alongside identified correlations between depression, chronic pain, and these variables.

CONCLUSION

The study highlights the impact of depression and chronic pain on fascial properties, emphasizing the need for further research in this domain to unravel the intricate connections and potential implications for treatment strategies.

Clinical reasoning skills of German and Dutch manual therapists: a cross-sectional study

INTRODUCTION

Reflective clinical reasoning (CR) is believed to play a crucial role in achieving an efficient therapy process, supported by evidence-based approaches that improve patient outcomes. The aim of this study was to evaluate the CR process of German manual therapists (MTs) using the CR skills of Dutch MTs as a reference.

METHODS

This cross-sectional study evaluated the CR process and diagnostic ability of German MTs. Dutch MTs served as the reference standard due to their experience with direct access. The CR skills were assessed using the Diagnostic Thinking Inventory (DTI), a questionnaire measuring diagnostic competence. Descriptive and inferential statistics were conducted to compare the groups. Subgroup analyses were performed to analyze the influence of work experience (in years) and the level of education on CR.

RESULTS

396 manual therapists (229 German and 167 Dutch) completed the DTI. Dutch MTs revealed higher DTI sum-scores compared to German MTs (p < .001; Cohen´s d = .41). Subgroup analyses regarding professional education revealed no significant differences in DTI sum-scores within German MTs and between both groups. In the subgroup analyses regarding professional experience, differences of moderate effect size were reached between German and Dutch novice MTs (in favor of Dutch novice MTs; p = .001; Cohen´s d = .62), and between German novice MTs and experienced German MTs (in favor of experienced German MTs; p < .001; Cohen´s d = .6).

CONCLUSION

The results suggest that academically educated German and Dutch MTs as well as experienced German and Dutch MTs are similar in terms of their hypothetical-deductive CR skills. In turn, German novice MTs seem to use hypothetical-deductive processing to a lesser extent compared to Dutch novice MTs and experienced German MTs, which in turn may support the hypothesis that the level of professional experience and education has a significant impact on the development of hypothetical-deductive CR skills.

[Physiotherapeutic differential diagnosis of back pain associated with endometriosis]

BACKGROUND

Endometriosis (EM) is one of the most common gynecologic conditions in our society. The diagnosis takes an average of 7 to 10 years. To shorten this period, this syndrome needs more attention. The aim of this article is to show overlaps between EM and low back pain (LBP) and to describe their relevance for physiotherapeutic screening.

OBJECTIVES

What clinical signs do the syndromes EM and LBP have in common and to what extent can physiotherapeutic screening take gynecological aspects into account and be adapted accordingly?

RESULTS

To answer this question, the two syndromes were screened for overlaps. These overlaps were then related to the existing literature and case studies. The current research situation shows overlaps of the two syndromes with regard to the etiology, the pain mechanism as well as a psychosocial aspect. The literature shows that more women than men are affected by LBP and other chronic pain syndromes. EM occurs almost exclusively in women and, like LBP, is considered a chronic pain syndrome. Thus, a common pain mechanism of the two syndromes is discussed in the literature. The most frequent overlap of the two syndromes is shown by the occurrence of LBP as a frequent symptom of EM. This connection can be justified by structural causes as well as by a reflex pain presentation.

CONCLUSION

In a physiotherapeutic setting, evidence of EM can be observed in the history and physical examination. Considering these factors may help shorten the diagnosis time of endometriosis by referring for further evaluation if gynecologic involvement is suspected in LBP. A comprehensive history is important and should cover urologic, gynecologic, as well as sexual history. In this article, the term woman is used to refer to the biological female sex and is not related to individual gender identity. The clinical picture mainly affects women, which is why in the following work, as far as it concerns the people suffering from the disease, it is not used in the opposite sense.

Low back pain as main symptom in Low-grade Appendiceal Mucinous Neoplasm (LAMN): A case report

BACKGROUND

Low back pain is the leading cause of disability worldwide. It is also the main cause of the limitation of activities and absence from work in much of the world and a cause of great economic burden. The greatest percentage of low back pain is classified as nonspecific (i.e. not attributable to a defined pathology), while the others may concern specific pathologies of the lumbar region or suggest pathologies of non-musculoskeletal origin. Consequently, evaluating any signs and symptoms mimicking musculoskeletal conditions is crucial.

CASE DESCRIPTION

This case report describes a 64-year-old female patient who first presented to the physiotherapist with two weeks of low back pain, complaining of a different clinical presentation than the previous episodes. The patient's pain started spontaneously and was located in the lumbar region over a diffuse area. Symptoms were constant throughout the day and did not change with movement. Based on the examination findings, the physiotherapist decided to make an urgent referral to the patient's General Practitioner.

OUTCOMES

Following ultrasound examination and Computed Tomography scan, an 8.5 cm mass was confirmed in the abdominal region. It was surgically removed, and a histological diagnosis of Low-grade Appendiceal Mucinous Neoplasm (LAMN) was made.

CONCLUSION

The physiotherapist's evaluation and decision-making process was fundamental in the patient's referral due to suspected pathology not within the scope of practice. This revealed a rare condition, which, according to the existing literature, is usually diagnosed in the event of collateral imaging findings or upon presentation of complex and/or emergency clinical pictures.

Brain white matter pathways of resilience to chronic back pain: a multisite validation

Chronic back pain (CBP) is a global health concern with significant societal and economic burden. While various predictors of back pain chronicity have been proposed, including demographic and psychosocial factors, neuroimaging studies have shown that brain characteristics can serve as robust predictors of CBP. However, large-scale, multisite validation of these predictors is currently lacking. In two independent longitudinal studies, we examined white matter diffusion imaging data and pain characteristics in patients with subacute back pain (SBP) over six- and 12-month periods. Diffusion data from individuals with CBP and healthy controls (HC) were analyzed for comparison. Whole-brain tract-based spatial statistics analyses revealed that a cluster in the right superior longitudinal fasciculus (SLF) tract had larger fractional anisotropy (FA) values in patients who recovered (SBPr) compared to those with persistent pain (SBPp), and predicted changes in pain severity. The SLF FA values accurately classified patients at baseline and follow-up in a third publicly available dataset (Area under the Receiver Operating Curve ~ 0.70). Notably, patients who recovered had FA values larger than those of HC suggesting a potential role of SLF integrity in resilience to CBP. Structural connectivity-based models also classified SBPp and SBPr patients from the three data sets (validation accuracy 67%). Our results validate the right SLF as a robust predictor of CBP development, with potential for clinical translation. Cognitive and behavioral processes dependent on the right SLF, such as proprioception and visuospatial attention, should be analyzed in subacute stages as they could prove important for back pain chronicity.

Evaluation of an electronic clinical decision support system (DeSSBack) to improve low back pain management: a pilot cluster randomized controlled trial

BACKGROUND

Low back pain (LBP) is a common reason for primary care consultation; yet doctors often find managing it challenging. An electronic decision support system for LBP (DeSSBack) was developed based on an evidence-based risk stratification tool to improve the management of patients with LBP in a Malaysian primary care setting. This pilot study aimed to assess the feasibility, acceptability, and preliminary effectiveness of DeSSBack for the conduct of a future definitive trial.

METHODS

A pilot cluster randomized controlled trial (cRCT) with qualitative interviews was conducted. Each primary care doctor was considered a cluster and randomized to either the control (usual practice) or intervention (DeSSBack) group. Patient outcomes including Roland-Morris Disability Questionnaire (RMDQ), Hospital Anxiety and Depression Scale, and a 10-point pain rating scale were measured at baseline and 2-month postintervention. The doctors in the intervention group were interviewed to explore feasibility and acceptability of using DeSSBack.

RESULTS

Thirty-six patients with nonspecific LBP participated in this study (intervention n = 23; control n = 13). Fidelity was poor among patients but good among doctors. The RMDQ and anxiety score had medium effect sizes of 0.718 and 0.480, respectively. The effect sizes for pain score (0.070) and depression score were small (0.087). There was appreciable acceptability and satisfaction with use of DeSSBack, as it was helpful in facilitating thorough and standardized management, providing appropriate treatment plans based on risk stratification, improving consultation time, empowering patient-centred care, and easy to use.

CONCLUSIONS

A future cRCT to evaluate the effectiveness of DeSSBack is feasible to be conducted in a primary care setting with minor modifications. DeSSBack was found useful by doctors and can be improved to enhance efficiency.

TRIAL REGISTRATION

The protocol of the cluster randomized controlled trial was registered at ClinicalTrials.gov (NCT04959669).

ADvAnced PhysioTherapy in MuSculosKeletal Triage: Investigating prognostic factors, healthcare utilisation and clinical outcomes (ADAPT MSK) - a cohort study protocol

BACKGROUND

Clinical specialist physiotherapist-led musculoskeletal triage clinics were introduced nationally in Ireland in 2011 to improve patient care and reduce waiting times for secondary care orthopaedics and rheumatology. Evidence has shown them to be effective in reducing waiting lists, however there are currently no data on longitudinal patient outcomes following clinic attendance. The primary aim of this cohort study is to identify predictors of pain and function outcomes up to one year following musculoskeletal triage review. Secondary aims include measuring self-reported use of healthcare resources over the 12-month follow-up period and to explore musculoskeletal phenotypes based on established prognostic factors for musculoskeletal pain. This is a prospective cohort study.

METHODS

ADvAnced PhysioTherapy in MuSculosKeletal Triage (ADAPT MSK) will recruit a cohort of 252 adults through musculoskeletal triage clinics across five secondary care sites in Ireland. The STrengthening the Reporting of Observational studies in Epidemiology (STROBE) guidelines will be adhered to for future reporting. Adults (≥ 18 years old) attending physiotherapist-led musculoskeletal triage clinics with musculoskeletal pain, who do not require surgical or consultant-led medical care will be considered for participation. Participant demographics, health literacy, healthcare utilisation, and self-report questionnaires on pain, function, musculoskeletal health, musculoskeletal risk stratification, fear of movement, and psychological distress will be obtained at baseline, with follow-ups at three, six, and 12 months. Primary outcomes are pain intensity and function. Secondary outcomes include musculoskeletal risk stratification status, musculoskeletal health, healthcare utilisation, and work-related factors. Descriptive statistics will be used to profile the participants and predictors of outcome will be assessed using multivariable linear regression. Musculoskeletal phenotypes will be explored using latent class analysis.

RESULTS

Results will be disseminated via peer-reviewed journal publication and presentation at national and international conferences. Engagement with a public patient involvement (PPI) panel will explore dissemination strategies for public and service user engagement.

Perspectives on chronic musculoskeletal pain management among healthcare professionals in Bhutan: A qualitative study

INTRODUCTION

Musculoskeletal pain disorders continue to be one of the leading causes of disability worldwide. Best practice care recommends patient-centred biopsychosocial models of care. Little is known about the chronic musculoskeletal pain management in low- and middle-income countries.

OBJECTIVES

To explore the management of chronic musculoskeletal pain by healthcare professionals in Bhutan.

METHODS

This study employed a qualitative design involving 19 Bhutanese healthcare professionals managing chronic musculoskeletal pain in Bhutan. We collected data using a semi-structured interview guide. Thematic analysis was done manually.

RESULTS

Healthcare professionals reported that patients rely on a combination of home remedies and seek help from local healers and hospitals for chronic musculoskeletal pain management. While healthcare professionals understand chronic musculoskeletal pain as multi-dimensional phenomenon, the primary focus was on identifying and treating structural anomalies. Time constraints, inadequate knowledge and skills, lack of confidence, facilities and expertise were reported as barriers to the effective management of chronic musculoskeletal pain. They proposed a need for clinical guidelines, relevant skills training and creating awareness of chronic musculoskeletal pain.

CONCLUSION

The management of chronic musculoskeletal pain in Bhutan is focused on identifying and treating physical abnormalities. Healthcare professionals consider psychosocial dimensions important but lack any form of actionable interventions in this domain.

Change in Pain-Related Anxiety Mediates the Effects of Psychophysiologic Symptom Relief Therapy (PSRT) on Pain Disability for Chronic Back Pain: Secondary Results from a Randomized Controlled Trial

Purpose

Widely used therapeutic approaches, such as cognitive-behavioral and mindfulness-based therapies, can improve pain and functioning in people with chronic back pain, but the magnitude and duration of their effects are limited. Our team developed a novel 12-week program, psychophysiologic symptom relief therapy (PSRT), to substantially reduce or eliminate pain and disability. This study examined whether PSRT helped more patients achieve large-magnitude (≥30%, ≥50%, ≥75%) reductions in back pain-related disability compared to mindfulness-based stress reduction (MBSR) and usual care (UC), and if the beneficial effects of PSRT were explained by reductions in pain-related anxiety following treatment.

Patients and Methods

Data from a three-armed randomized controlled trial were used (N=35 adults with chronic back pain). Change scores (baseline to 4-, 8-, 13-, and 26-weeks post-enrollment) were computed for back pain disability (RDQ) and pain-related anxiety (PASS-20). Fisher's exact tests and mediation analyses were conducted.

Results

Compared to MBSR and UC, PSRT helped significantly more patients achieve ≥75% reductions in back pain disability at all timepoints and in pain anxiety at all timepoints except 13-weeks. Change in pain anxiety significantly mediated the relationship between treatment group and change in back pain disability from baseline to 26-weeks.

Conclusion

PSRT helped more patients achieve substantial reductions in disability than an established treatment (MBSR) and usual care. Findings indicate reduced pain anxiety may be a mechanism by which PSRT confers long-term benefits on disability. Importantly, this work aims to move the field toward more precise and effective treatment for chronic back pain.

Preventing Suicide: Time to Mobilize the Physical Therapist Workforce

Each year, approximately 700,000 people, including 46,000 Americans, die by suicide; however, many more people experience suicidal thoughts and behaviors. Historically, the prevention of suicide has largely been the domain of mental health professionals working within specialist mental health care settings. An issue with this approach is that many individuals who experience suicidal ideation never disclose these thoughts to a mental health professional. The nonprofessional and paraprofessional mental health movement aims to bring suicide prevention to the people who need it, rather than wait for them to seek help. The nonprofessional and paraprofessional mental health movement does so by upskilling people who are not recognized as mental health professionals but may have contact with people experiencing suicidal thoughts and behaviors. In this Perspective, we argue that physical therapists are well-positioned to engage in suicide prevention. For example, physical therapists working in pain management are likely to frequently encounter clients experiencing suicidal thoughts and behaviors. Physical therapy is also viewed as a physical health profession, meaning that they may have contact with a broad range of populations at high risk of suicide who may be difficult to reach through traditional channels (eg, men from rural communities). Physical therapists will require training on how to provide crisis support, including how to link clients with appropriate mental health services. However, given the size of the physical therapist workforce globally, the impact of mobilizing the physical therapist workforce could be significant.

Assessing Serious Spinal Pathology Using Bayesian Network Decision Support: Development and Validation Study

BACKGROUND

Identifying and managing serious spinal pathology (SSP) such as cauda equina syndrome or spinal infection in patients presenting with low back pain is challenging. Traditional red flag questioning is increasingly criticized, and previous studies show that many clinicians lack confidence in managing patients presenting with red flags. Improving decision-making and reducing the variability of care for these patients is a key priority for clinicians and researchers.

OBJECTIVE

We aimed to improve SSP identification by constructing and validating a decision support tool using a Bayesian network (BN), which is an artificial intelligence technique that combines current evidence and expert knowledge.

METHODS

A modified RAND appropriateness procedure was undertaken with 16 experts over 3 rounds, designed to elicit the variables, structure, and conditional probabilities necessary to build a causal BN. The BN predicts the likelihood of a patient with a particular presentation having an SSP. The second part of this study used an established framework to direct a 4-part validation that included comparison of the BN with consensus statements, practice guidelines, and recent research. Clinical cases were entered into the model and the results were compared with clinical judgment from spinal experts who were not involved in the elicitation. Receiver operating characteristic curves were plotted and area under the curve were calculated for accuracy statistics.

RESULTS

The RAND appropriateness procedure elicited a model including 38 variables in 3 domains: risk factors (10 variables), signs and symptoms (17 variables), and judgment factors (11 variables). Clear consensus was found in the risk factors and signs and symptoms for SSP conditions. The 4-part BN validation demonstrated good performance overall and identified areas for further development. Comparison with available clinical literature showed good overall agreement but suggested certain improvements required to, for example, 2 of the 11 judgment factors. Case analysis showed that cauda equina syndrome, space-occupying lesion/cancer, and inflammatory condition identification performed well across the validation domains. Fracture identification performed less well, but the reasons for the erroneous results are well understood. A review of the content by independent spinal experts backed up the issues with the fracture node, but the BN was otherwise deemed acceptable.

CONCLUSIONS

The RAND appropriateness procedure and validation framework were successfully implemented to develop the BN for SSP. In comparison with other expert-elicited BN studies, this work goes a step further in validating the output before attempting implementation. Using a framework for model validation, the BN showed encouraging validity and has provided avenues for further developing the outputs that demonstrated poor accuracy. This study provides the vital first step of improving our ability to predict outcomes in low back pain by first considering the problem of SSP.

Early experience of a local pathway on the waiting time for MRI in patients presenting to a UK district general hospital with suspected cauda equina syndrome

AIM

This study evaluated the impact of the Salisbury Protocol for Assessment of Cauda Equina Syndrome (SPACES) on the waiting time for MRI in patients presenting with suspected Cauda Equina Syndrome (sCES) within a UK district general hospital.

PATIENTS AND METHODS

All consecutive patients undergoing an MRI scan in our hospital, for sCES, over a 12 month period, prior to and following the introduction of SPACES, were identified. Patient's gender, age, MRI diagnosis, time from MRI request to imaging and outcome were recorded.

RESULTS

In the year prior to the introduction of SPACES, 66 patients underwent MRI for sCES, out of which 10.6% had cauda equina compression (CEC), 63.5% had other spinal pathology and 25% had a normal scan. In the year after introduction of SPACES, 160 patients underwent MRI for sCES out of which 6.2% had CEC, 70.7% had other spinal pathology and 23% had a normal scan. Despite the referrals for sCES increasing by more than 2-fold following the introduction of SPACES, the median time from MRI request to scan decreased from 9.1 to 4.2 hours (p = 0.106, Mann-Whitney-U) and the number of patients transferred to the regional hub hospital decreased from 7 to 3.

CONCLUSION

Implementation of SPACES for patients with sCES resulted in a substantial reduction in waiting time for MRI and decreased the number of transfers to the regional hub hospital. Based on our early experience, we encourage other centres within the UK to introduce such a pathway locally, to improve the management of patients with sCES.

What Factors Do Clinicians, Coaches, and Athletes Perceive Are Associated With Recovery From Low Back Pain in Elite Athletes? A Concept Mapping Study

OBJECTIVE: Identify factors that elite sport clinicians, coaches, and athletes perceive are associated with low back pain (LBP) recovery. DESIGN: Concept mapping methodology. METHOD: Participants brainstormed, sorted (thematically), and rated (5-point Likert scales: importance and feasibility) statements in response to the prompt, "What factors are associated with the recovery of an elite athlete from low back pain?" Data cleaning, analysis (multidimensional scaling, hierarchical cluster analysis, and descriptive statistics), and visual representation (cluster map and Go-Zone graph) were conducted following concept mapping guidelines. RESULTS: Participants (brainstorming, n = 56; sorting, n = 34; and rating, n = 33) comprised 75% clinicians, 15% coaches, and 10% athletes and represented 13 countries and 17 sports. Eighty-two unique and relevant statements were brainstormed. Sorting resulted in 6 LBP recovery-related themes: (1) coach and clinician relationships, (2) inter-disciplinary team factors, (3) athlete psychological factors, (4) athlete rehabilitation journey, (5) athlete non-modifiable risk factors, and (6) athlete physical factors. Participants rated important recovery factors as follows: athlete empowerment and psychology, coach-athlete and athlete-clinician relationships, care team communication, return-to-sport planning, and identifying red flags. CONCLUSION: Factors perceived as important to LBP recovery in elite athletes align with the biopsychosocial model of community LBP management. Clinicians should consider that an athlete's psychology, relationships, care team communication, and rehabilitation plan may be as important to their LBP recovery as the formulation of a diagnosis or the medications or exercises prescribed.

Chondrosarcoma of the spine-a case report

CASE

A 73-year-old male patient presented with a 3-month history of back pain. In bone scintigraphy and the FDG PET-CT scan (fluorodeoxyglucose positron-emission computed tomography), highly suspect uptake levels were found in TH12-L1. Accordingly, an osteodestructive process was found on MRI (magnetic resonance imaging). Following a successfully performed biopsy of TH12, histologic analysis of the bone material revealed a chondrosarcoma (G1; T4N2M0). Complete resection of the tumor was successfully performed, since chondrosarcoma are resistant to radiation and chemotherapy.

CONCLUSION

As chondrosarcoma is a rare bone neoplasm, it must be considered in the differential diagnosis of lower back pain to initiate adequate treatment.

Effectiveness and Consequences of Direct Access in Physiotherapy: A Systematic Review

Background. Direct access in physiotherapy (DAPT) occurs when a patient has the ability to self-refer to physical therapy without physician referral. This model of care in musculoskeletal diseases (MSDs) has shown better outcomes than the traditional-based medical model of care that requires physician referral to access physiotherapist services. This traditional physician referral often results in a delay in care. Unfortunately, DAPT is still not permitted in many countries. Objectives. The primary objective of this systematic review was to compare the effectiveness, safety, and the accuracy of DAPT compared to the physician-led model of care for the management of patients with musculoskeletal disorders. The secondary objective of the present study is to define the physiotherapists' characteristics or qualifications involved in DAPT. Materials and methods. Databases searched included: Medline, Scopus and Web of Science. Databases were searched from their inception to July 2022. Research strings were developed according to the PICO model of clinical questions (patient, intervention, comparison, and outcome). Free terms or synonyms (e.g., physical therapy; primary health care; direct access; musculoskeletal disease; cost-effectiveness) and when possible MeSH (Medical Subject Headings) terms were used and combined with Boolean operators (AND, OR, NOT). Risk of bias assessment was carried out through Version 2 of the Cochrane risk-of-bias tool (ROB-2) for randomized controlled trials (RCTs) and the Newcastle Ottawa Scale (NOS) for observational studies. Authors conducted a qualitative analysis of the results through narrative analysis and narrative synthesis. The narrative analysis was provided for an extraction of the key concepts and common meanings of the different studies, while the summary narrative provided a textual combination of data. In addition, a quantitative analysis was conducted comparing the analysis of the mean and differences between the means. Results. Twenty-eight articles met the inclusion criteria and were analyzed. Results show that DAPT had a high referral accuracy and a reduction in the rate of return visits. The medical model had a higher use of imaging, drugs, and referral to another specialist. DAPT was found to be more cost-effective than the medical model. DAPT resulted in better work-related outcomes and was superior when considering patient satisfaction. There were no adverse events noted in any of the studies. In regard to health outcomes, there was no difference between models. ROB-2 shows an intermediate risk of bias risk for the RCTs with an average of 6/9 points for the NOS scale for observational studies. Conclusion. DAPT is a safe, less expensive, reliable triage and management model of care that results in higher levels of satisfaction for patients compared to the traditional medical model.

The experiences of uncertainty amongst musculoskeletal physiotherapists in first contact practitioner roles within primary care

AIM

The aim of this research was to explore the experiences of uncertainty amongst Musculoskeletal First Contact Practitioners working in primary care.

BACKGROUND

The Musculoskeletal First Contact Practitioner role involves advanced physiotherapists providing an alternative to the GP by acting as first point of contact for people presenting to primary care with musculoskeletal conditions. Limited research into the role exists but the first-contact aspect, clinical complexity and time pressures are deemed to contribute to uncertainty within the role.

METHOD

A qualitative research design was undertaken using a hermeneutic interpretative phenomenological approach. Data was collected using semi-structured interviews with subsequent thematic analysis of the data.

FINDINGS

Eight participants working as Musculoskeletal First Contact Practitioners across England were recruited using purposive sampling. Five themes were identified: (1) Role clarity within primary care, (2) Burden of responsibility, (3) Preparedness for the primary care environment, (4) 'I'm not really sure how long I am going to stay in this role', (5) Mitigating uncertainty.

CONCLUSION

This study demonstrates the multifaceted phenomenon of uncertainty amongst Musculoskeletal First Contact Practitioners. Uncertainty appeared to be influenced by the primary care environment, preparedness for the role and perceived burden of responsibility. Diagnostic uncertainty was prevalent with concerns of missing serious pathology evident. The impact of uncertainty on wellbeing was linked to possible burnout and retention issues. Consultation approaches, access to support networks and a cultural shift in tolerating uncertainty were reported to mitigate uncertainty. Further research into possible differences in experiences related to employment models appears warranted.

Red flags to screen for vertebral fracture in people presenting with low back pain

BACKGROUND

Low back pain is a common presentation across different healthcare settings. Clinicians need to confidently be able to screen and identify people presenting with low back pain with a high suspicion of serious or specific pathology (e.g. vertebral fracture). Patients identified with an increased likelihood of having a serious pathology will likely require additional investigations and specific treatment. Guidelines recommend a thorough history and clinical assessment to screen for serious pathology as a cause of low back pain. However, the diagnostic accuracy of recommended red flags (e.g. older age, trauma, corticosteroid use) remains unclear, particularly those used to screen for vertebral fracture.

OBJECTIVES

To assess the diagnostic accuracy of red flags used to screen for vertebral fracture in people presenting with low back pain. Where possible, we reported results of red flags separately for different types of vertebral fracture (i.e. acute osteoporotic vertebral compression fracture, vertebral traumatic fracture, vertebral stress fracture, unspecified vertebral fracture).

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 26 July 2022.

SELECTION CRITERIA

We considered primary diagnostic studies if they compared results of history taking or physical examination (or both) findings (index test) with a reference standard test (e.g. X-ray, magnetic resonance imaging (MRI), computed tomography (CT), single-photon emission computerised tomography (SPECT)) for the identification of vertebral fracture in people presenting with low back pain. We included index tests that were presented individually or as part of a combination of tests.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data for diagnostic two-by-two tables from the publications or reconstructed them using information from relevant parameters to calculate sensitivity, specificity, and positive (+LR) and negative (-LR) likelihood ratios with 95% confidence intervals (CIs). We extracted aspects of study design, characteristics of the population, index test, reference standard, and type of vertebral fracture. Meta-analysis was not possible due to heterogeneity of studies and index tests, therefore the analysis was descriptive. We calculated sensitivity, specificity, and LRs for each test and used these as an indication of clinical usefulness. Two review authors independently conducted risk of bias and applicability assessment using the QUADAS-2 tool.

MAIN RESULTS

This review is an update of a previous Cochrane Review of red flags to screen for vertebral fracture in people with low back pain. We included 14 studies in this review, six based in primary care, five in secondary care, and three in tertiary care. Four studies reported on 'osteoporotic vertebral fractures', two studies reported on 'vertebral compression fracture', one study reported on 'osteoporotic and traumatic vertebral fracture', two studies reported on 'vertebral stress fracture', and five studies reported on 'unspecified vertebral fracture'. Risk of bias was only rated as low in one study for the domains reference standard and flow and timing. The domain patient selection had three studies and the domain index test had six studies rated at low risk of bias. Meta-analysis was not possible due to heterogeneity of the data. Results from single studies suggest only a small number of the red flags investigated may be informative. In the primary healthcare setting, results from single studies suggest 'trauma' demonstrated informative +LRs (range: 1.93 to 12.85) for 'unspecified vertebral fracture' and 'osteoporotic vertebral fracture' (+LR: 6.42, 95% CI 2.94 to 14.02). Results from single studies suggest 'older age' demonstrated informative +LRs for studies in primary care for 'unspecified vertebral fracture' (older age greater than 70 years: 11.19, 95% CI 5.33 to 23.51). Results from single studies suggest 'corticosteroid use' may be an informative red flag in primary care for 'unspecified vertebral fracture' (+LR range: 3.97, 95% CI 0.20 to 79.15 to 48.50, 95% CI 11.48 to 204.98) and 'osteoporotic vertebral fracture' (+LR: 2.46, 95% CI 1.13 to 5.34); however, diagnostic values varied and CIs were imprecise. Results from a single study suggest red flags as part of a combination of index tests such as 'older age and female gender' in primary care demonstrated informative +LRs for 'unspecified vertebral fracture' (16.17, 95% CI 4.47 to 58.43). In the secondary healthcare setting, results from a single study suggest 'trauma' demonstrated informative +LRs for 'unspecified vertebral fracture' (+LR: 2.18, 95% CI 1.86 to 2.54) and 'older age' demonstrated informative +LRs for 'osteoporotic vertebral fracture' (older age greater than 75 years: 2.51, 95% CI 1.48 to 4.27). Results from a single study suggest red flags as part of a combination of index tests such as 'older age and trauma' in secondary care demonstrated informative +LRs for 'unspecified vertebral fracture' (+LR: 4.35, 95% CI 2.92 to 6.48). Results from a single study suggest when '4 of 5 tests' were positive in secondary care, they demonstrated informative +LRs for 'osteoporotic vertebral fracture' (+LR: 9.62, 95% CI 5.88 to 15.73). In the tertiary care setting, results from a single study suggest 'presence of contusion/abrasion' was informative for 'vertebral compression fracture' (+LR: 31.09, 95% CI 18.25 to 52.96).

AUTHORS' CONCLUSIONS

The available evidence suggests that only a few red flags are potentially useful in guiding clinical decisions to further investigate people suspected to have a vertebral fracture. Most red flags were not useful as screening tools to identify vertebral fracture in people with low back pain. In primary care, 'older age' was informative for 'unspecified vertebral fracture', and 'trauma' and 'corticosteroid use' were both informative for 'unspecified vertebral fracture' and 'osteoporotic vertebral fracture'. In secondary care, 'older age' was informative for 'osteoporotic vertebral fracture' and 'trauma' was informative for 'unspecified vertebral fracture'. In tertiary care, 'presence of contusion/abrasion' was informative for 'vertebral compression fracture'. Combinations of red flags were also informative and may be more useful than individual tests alone. Unfortunately, the challenge to provide clear guidance on which red flags should be used routinely in clinical practice remains. Further research with primary studies is needed to improve and consolidate our current recommendations for screening for vertebral fractures to guide clinical care.

Immediate systemic neuroimmune responses following spinal mobilisation and manipulation in people with non-specific neck pain: a randomised placebo-controlled trial

Spinal mobilisation/manipulation is a common intervention for spinal pain, yet the working mechanisms are largely unknown. A randomised placebo-controlled trial was conducted to (1) compare the immediate neuroimmune responses following spinal mobilisation/manipulation and placebo spinal mobilisation/manipulation; (2) compare the immediate neuroimmune responses of those with a good outcome with those of a poor outcome following spinal mobilisation/manipulation; and (3) explore the association between neuroimmune responses and pain reduction. One hundred patients were randomly allocated to spinal mobilisation/manipulation or a placebo mobilisation/manipulation. Primary outcomes were whole blood in-vitro evoked released concentrations of IL-1β and TNF-α measured 10 min and 2 h after the intervention. Immediate effects were studied because successful mobilisation/manipulation is often associated with immediate pain reduction, and immediate neuroimmune responses are less affected by potential confounders than long-term responses. Secondary outcomes included multiple systemic inflammatory marker concentrations, phenotypic analysis of white blood cells and clinical outcomes. Outcomes were compared between the experimental and placebo group, and between people with a good and poor outcome in the experimental group. Estimates of intervention effects were based on intention-to-treat analyses, by using linear mixed-effect models. Although there was a substantial difference in pain reduction between groups (mean (SD) difference visual analogue scale: 30 (21) mm at 10 min and 32 (21) mm at 2 h (p < 0.001) in favour of mobilisation/manipulation, there were no differences in primary outcomes between groups or between people with a good and poor outcome (p ≥ 0.10). In conclusion, possible neuroimmune responses following spinal mobilisations/manipulation cannot be identified at a systemic level. Future research may focus on longer treatment duration and more localised neuroimmune responses.

Care for the patient with low back pain

ABSTRACT

Low back pain (LBP) continues to be one of the most common conditions leading patients to seek medical care globally. The NP is on the frontline, playing an integral role in caring for patients with LBP. Understanding the etiology of LBP is essential in the treatment.

Guideline adherent screening and referral: do third year Doctor of Physical Therapy students identify red and yellow flags within descriptive patient cases? a United States based survey study

INTRODUCTION

The need for early detection and appropriate management of flags in physical therapy has been established. The lack of early detection has been shown to lead to poor outcomes such as serious pathology, increased disability, prolonged symptoms, and increased healthcare utilization.

OBJECTIVE

The main purpose of this survey study was to assess third-year Doctor of Physical Therapy (DPT) students' adherence to clinical practice guidelines specifically in the identification and management of red and yellow flags through a case-based approach.

METHODS

A survey including three different flag case scenarios was sent to DPT students in 15 geographically diverse physical therapy programs. Previously published case scenarios measuring adherence to practice guidelines were used. Correlational analyses were performed to link student demographic details and guideline adherent management.

RESULTS

The survey was completed by 64 students. Guideline adherent management was greater for red flags (85%) than yellow flag cases (25% and 42%). No significant relationship was noted between the student details and guideline adherent management.

CONCLUSION

DPT students may need additional educational content related to yellow flag screening. Educators may consider utilizing published red and yellow flag cases to guide decision-making and highlight best screening practices.

A Model of Triage of Serious Spinal Pathologies and Therapeutic Options Based on a Delphi Study

Background and Objectives: The relevance of red flags in serious spinal pathology (SSP) has evolved throughout the last years. Recently, new considerations have been proposed to expand the consideration of red flags. The purpose of this study was to determine, approve and test a model for the triage and management process of SSPs based on the latest data available in the literature. Materials and Methods: The SSP model was initially built on the basis of a literature review. The model was further determined and approved by an expert panel using a Delphi process. Finally, clinical scenarios were used to test the applicability of the model. Results: After three rounds of the Delphi process, panellists reached a consensus on a final version of the model. The use of clinical scenarios by experts brought about reflexive elements both for the determined model and for the SSPs depicted in the clinical cases. Conclusions: The validation of the model and its implementation in the clinical field could help assess the skills of first-line practitioners managing spinal pain patients. To this end, the development of additional clinical scenarios fitting the determined model should be further considered.

Failed Back Surgery Syndrome: No Longer a Surgeon's Defeat-A Narrative Review

The introduction of the term Persistent Spinal Pain Syndrome (PSPS-T1/2), replacing the older term Failed Back Surgery Syndrome (FBSS), has significantly influenced our approach to diagnosing and treating post-surgical spinal pain. This comprehensive review discusses this change and its effects on patient care. Various diagnostic methods are employed to elucidate the underlying causes of back pain, and this information is critical in guiding treatment decisions. The management of PSPS-T1/2 involves both causative treatments, which directly address the root cause of pain, and symptomatic treatments, which focus on managing the symptoms of pain and improving overall function. The importance of a multidisciplinary and holistic approach is emphasized in the treatment of PSPS-T1/2. This approach is patient-centered and treatment plans are customized to individual patient needs and circumstances. The review concludes with a reflection on the impact of the new PSPS nomenclature on the perception and management of post-surgical spinal pain.

Short-Term Changes in Posture and Pain of the Neck and Lower Back of Women Undergoing Lipoabdominoplasty: A Case Series Report

Objective

The purpose of this study was to analyze short-term variations in posture and intensity of neck and lower back pain in women undergoing lipoabdominoplasty.

Methods

This prospective case series study involved 17 women (age 43 ± 12 years, presurgical body mass index 27.0 ± 3.7 kg/m2). Participants were assessed preoperatively (T0) and at 15 (T15) and 30 days (T30) after surgery for clinical data (number of pregnancies, number of deliveries, presurgical body mass), neck and lower back angles calculated by photogrammetry, and pain intensity by numeric pain rating scale. Postoperative complications were assessed at T15 and T30.

Results

After adjusting for age and presurgical body mass index, there was an increase in forward head position in T15 and a return by T30 (marginal R2 = 0.411). The lower back showed an increase in flexion at T15 and return by T30 (marginal R2 = 0.266). No statistical evidence of significance was observed for changes in the intensity of neck (P > .355) or lower back (P > .293) pain. Complications were mild and common at T15; most of them resumed at T30.

Conclusion

A transient, nonlinear compensatory change in neck and lower back lordosis was observed 15 days after lipoabdominoplasty, with almost full recovery in the short term (30 days). No systematic change in pain intensity was observed within this period. Postsurgical complications were mild and common, and most of them resumed shortly after surgery.

Physiotherapy Screening for Referral of a Patient with Peripheral Arterial Disease Masquerading as Sciatica: A Case Report

Many causes potentially underline pain in the lower extremities, presenting a real challenge for primary care clinicians in the recognition of the source of the patient's complaints. Peripheral arterial disease (PAD) is defined as a total or partial blockage of the vessels that supply blood from the heart to the periphery. PAD of the lower extremities may masquerade as lumbosacral radiculopathy (LSR)-a common source of leg pain. Physiotherapists should be able to screen for PAD in people presenting with pain in the lower extremities. Failure to correctly screen for PAD could put the patient at risk of severe disability and possible permanent sequelae. This case report outlines the relevant concepts relating to the pathophysiology, screening, and differential diagnosis of PAD, and then further describes the relevant findings from the history and physical examination from the physiotherapist's perspective in a patient with an unusual symptom presentation. Although the patient was referred by a physician with a diagnosis of LSR, our case highlights the pivotal role of skilled physiotherapists in triaging a severe lower-limb PAD in need of referral. Therefore, this case report aims to increase clinicians' awareness of the clinical features of a complex case of PAD.

Modernizing patient-centered manual therapy: Findings from a Delphi study on orthopaedic manual therapy application

BACKGROUND

Recent literature challenges the process by which orthopaedic manual therapy (OMT) has traditionally been applied. Progressive understanding of the complexities surrounding OMT analgesia and the decreased reliance on technique specific characteristics in determining treatment effectiveness promotes an update to training paradigms related to OMT.

OBJECTIVES

The purpose of this Delphi study was to establish consensus on what trainees should be focusing on when demonstrating OMT techniques and how candidates for OMT should be identified.

DESIGN

An international three-round Delphi study following recommended guidelines for conducting and reporting of Delphi studies (CREDES) was performed.

METHODS

One-hundred sixty-four expert manual therapy educators were identified for participation across four countries. Participants were asked to provide what concepts trainees should be focusing on when demonstrating OMT techniques and how candidates for OMT should be identified. Twenty-one themes were identified for each question.

RESULTS

Twenty-eight participants completed all three rounds of the Delphi. Consensus was reached on nineteen themes and eighteen themes respectively. Results from this Delphi stress patient-centered care within a biopsychosocial pain management model. Representation across all pillars of evidence-based practice were represented. Themes reaching consensus within this study favored the importance of neurophysiological, psychological, and biomechanical principles.

CONCLUSION

This Delphi presents consensus-based recommendations for what manual therapy trainees should focus on when demonstrating OMT techniques and on how candidates for OMT should be identified. These findings in collaboration with previous consensus recommendations on concepts to focus on within OMT education promote restructuring of OMT curriculum to evidence-based patient-centered care models.

Diagnosis Value of Patient Evaluation Components Applicable in Primary Care Settings for the Diagnosis of Low Back Pain: A Scoping Review of Systematic Reviews

Low back pain ranks as the leading cause of years lived with disability worldwide. Although best practice guidelines share a consistent diagnostic approach for the evaluation of patients with low back pain, confusion remains as to what extent patient history and physical examination findings can inform management strategies. The aim of this study was to summarize evidence investigating the diagnostic value of patient evaluation components applicable in primary care settings for the diagnosis of low back pain. To this end, peer-reviewed systematic reviews were searched in MEDLINE, CINAHL, PsycINFO and Cochrane databases from 1 January 2000 to 10 April 2023. Paired reviewers independently reviewed all citations and articles using a two-phase screening process and independently extracted the data. Of the 2077 articles identified, 27 met the inclusion criteria, focusing on the diagnosis of lumbar spinal stenosis, radicular syndrome, non- specific low back pain and specific low back pain. Most patient evaluation components lack diagnostic accuracy for the diagnosis of low back pain when considered in isolation. Further research is needed to develop evidence-based and standardized evaluation procedures, especially for primary care settings where evidence is still scarce.

Cauda equina screening in Physiotherapy: A qualitative study of physiotherapists in a community musculoskeletal service: Are we asking the right questions and are we asking the questions right?

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. Thirty physiotherapists working in a community musculoskeletal service were purposively sampled and participated in semi-structured interviews. Data was transcribed and thematically analysed. All participants routinely asked bladder, bowel function and saddle anaesthesia screening questions although only 9 routinely asked about sexual function. Whether questions are asked in the correct way has never been studied. Sufficient depth of questioning, using lay terminology and explicit language was achieved by two-thirds of participants. Less than half of the participants framed the questions before asking them and only 5 participants combined all four dimensions. Whilst most clinicians felt comfortable asking general CES questions, half reported feeling uncomfortable when asking about sexual function. Issues around; gender, culture and language were also highlighted. Four main themes emerged from this study; i) Physiotherapists ask the right questions but frequently omit sexual function questions, ii) mostly, Physiotherapists ask CES questions in a way that patients understand however, there needs to be improvement in framing the context of the questions, iii) Physiotherapists generally feel comfortable with CES screening but there is some awkwardness surrounding discussion of sexual function and iv) Physiotherapists perceive there to be barriers to effective CES screening caused by culture and language.

Recognition of Prodromal Hypoglossal Nerve Palsy Presenting with Neck Pain as Primary Complaint: Findings from a Rare Case Report in Direct Access Physiotherapy during the COVID-19 Pandemic

Neck pain (NP) is the second most common musculoskeletal disorder. Spinal cysts (SCs) are cystic dilatations of the synovial sheaths in joints and tendons. SCs are extremely rare in the cervical spine. Typically, patients are unaware of having an SC due to its asymptomatic nature; however, when cervical SC extends, its volume could compress the surrounding structures, such as the hypoglossal nerve. Isolated hypoglossal nerve palsy (HNP) is very rare and typically presents with unilateral atrophy of the musculature of the tongue and contralateral tongue deviation. Often, patients with HNP also report occipital/neck pain. A 75-year-old man with occipital/neck pain as a primary complaint. Although difficult to observe because of the filtering facepiece two mask, difficulties in articulation and sialorrhea during the interview were noticed. These latter were cues to consider CN examination that revealed CN XII palsy. This prompted a referral for further examination that revealed an SC compressing the right hypoglossal canal. The patient was not considered a surgical candidate and was managed conservatively. This case report outlines the relevant findings relating to the triage of a rare isolated hypoglossal nerve palsy from the physiotherapist's perspective within a complex setting because of the COVID-19 pandemic. Although referred with a diagnosis of cervical radiculopathy, our case highlights that skilled physiotherapists may play a fundamental role in both the recognition and, when applicable, subsequent novel management of a non-musculoskeletal presentation.

Management of Low Back Pain: Do Physiotherapists Know the Evidence-Based Guidelines?

BACKGROUND

Clinical practice guidelines promote bio-psychosocial management of patients suffering from low back pain (LBP). The objective of this study was to examine the current knowledge, attitudes and beliefs of physiotherapists about a guideline-adherent approach to LBP and to assess the ability of physiotherapists to recognise signs of a specific LBP in a clinical vignette.

METHODS

Physiotherapists were recruited to participate in an online study. They were asked to indicate whether they were familiar with evidence-based guidelines and then to fill in the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), Back Pain Attitudes Questionnaire (Back-PAQ), Neurophysiology of Pain Questionnaire (NPQ), as well as questions related to two clinical vignettes.

RESULTS

In total, 527 physiotherapists participated in this study. Only 38% reported being familiar with guidelines for the management of LBP. Sixty-three percent of the physiotherapists gave guideline-inconsistent recommendations regarding work. Only half of the physiotherapists recognised the signs of a specific LBP.

CONCLUSIONS

The high proportion of physiotherapists unfamiliar with guidelines and demonstrating attitudes and beliefs not in line with evidence-based management of LBP is concerning. It is crucial to develop efficient strategies to enhance knowledge of guidelines among physiotherapists and increase their implementation in clinical practice.

Physiotherapy Screening for Referral of a Patient with Patent Foramen Ovale Presenting with Neck Pain as Primary Complaint: A Case Report

Neck pain is a common musculoskeletal disorder encountered by physiotherapists. However, it may be the early manifestation of more alarming conditions, such as cardiovascular diseases mimicking musculoskeletal pain. Patent foramen ovale (PFO) is a congenital heart defect consisting of a small opening between the right and the left atrium. A 56-year-old male presented with neck pain and head heaviness as primary complaints. The cardiovascular profile and the behavioral symptoms led the physiotherapist to find an exaggerated blood pressure response during exercise; in addition to subtle neurological signs, this prompted the physiotherapist to make an urgent referral. At the emergency department a PFO was diagnosed. To the best of the authors' knowledge, this is the first case to describe a rare clinical presentation of a PFO presenting neck pain as primary complaint. This case report emphasizes the importance for physiotherapists to be able to triage patients for conditions outside their scope suggestive of further medical investigation.

Impact of single multidisciplinary triage system and straight to test process evaluation at surrey integrated musculoskeletal services

Purpose

Orthopaedics, rheumatology, pain management, specialist radiology and therapy services were brought under one umbrella to form Northwest Surrey integrated musculoskeletal (IMSK) services and introduced advance clinical practice, a multi-disciplinary team triage with a formalised straight to test (STT) process defined in 2018. Historically, prior to these services' integration, there were a primary and second care triage systems within individual specialities. The aim of this service evaluation is to assess the impact of a single IMSK multidisciplinary triage (MDT) system and the efficacy of STT from triage, which allows patients to be sent for diagnostics based on the cluster of symptoms and past medical history in order to achieve early identification of serious pathologies. This is a complex adaptive system with pathways spanning into the core areas of orthopaedics, rheumatology, therapies, pain management services, radiology and some less frequent specialities such as neurology, oncology, vascular and gynaecology. One of the objectives of this study was to identify how many referrals were triaged to consultants, Advance practice and therapies. In addition, the authors wanted to highlight the proportion of referrals that were sent straight to test from triage and the percentage of these that had sinister pathology identified. This information would then be compared against existing red flag literature to identify common themes. This study aims to discuss the aforementioned objectives.

Design/methodology/approach

Data were extracted retrospectively from a hospital database from January to December 2019 for all the adult musculoskeletal service referrals. The data collected were analysed on a Microsoft Excel sheet with information including date of triage, hospital number, ordering clinician, body part, type of diagnostic, indications for scanning, outcome for STT, serious pathology findings (named code 5 within our trust) and outcome of appointment.

Findings

A total of 47,039 referrals were received into the IMSK service. Of these referrals 19,967 were directly referred to therapies, with 27,072 referrals received into the IMSK service MDT process. Within triage, 718 patients were directed to STT to rule out serious pathology. A total of 28 patients (3.9%) had sinister pathology identified on their investigation. A total of 46% of patients were discharged from their first consultation following STT. Overall, 50% of the total number of referrals into the IMSK service was seen by advanced practitioners with 16% of patients directed to consultants with pre-consultation diagnostic work up.

Originality/value

This service evaluation highlights that STT allows early access to diagnostics, resulting in quicker access to identification of sinister pathology. A one stop MDT system has been shown to be effective in guiding the referral to the right place with increased referrals into allied health advance practice clinics and access to therapies directly. It has resulted in a reduction of unwarranted referrals to consultant care, duplication of investigations and identified patients on multiple pathways.

Headache, Loss of Smell, and Visual Disturbances: Symptoms of SARS-CoV-2 Infection? A Case Report

OBJECTIVE

The purpose of this case report is to describe the main components of the history and physical examination that led to idiopathic intracranial hypertension differential diagnosis, which initially was investigated as COVID-19.

METHODS (CASE DESCRIPTION)

A 28-year-old woman complaining of constant headache and loss of smell and taste was suspected as SARS-CoV-2 infection by her general practitioner. She underwent 3 molecular swab tests, all negative, then decided to seek her physical therapist for relieving headache.

RESULTS

The full cranial nerve examination revealed impaired olfactory (CNI), abducens (CN VI), and facial (CN VII) nerves, leading the physical therapist to refer the patient to a neurosurgeon for a suspected central nervous system involvement. The neurosurgeon prescribed a detailed MRI and an ophthalmologic examination, which allowed for the final diagnosis of idiopathic intracranial hypertension.

CONCLUSION

An urgent lumbo-peritoneal shunting surgery resolved the patient's symptoms and saved her sight. Despite the ongoing COVID-19 pandemic, health care professionals must pay attention to properly investigating patients' signs and symptoms using comprehensive clinical reasoning, considering the screening for referral to specialist medical attention.

IMPACT

A thorough physical examination is required for every patient even if patients' signs and symptoms are in line with apparent common and widespread pathologies. Cranial nerve evaluation is an essential component of the physical therapist assessment and decision-making process. The ongoing pandemic highlighted the fundamental assistance of physical therapists toward physicians in the screening and management of musculoskeletal diseases.

A guide to identify cervical autonomic dysfunctions (and associated conditions) in patients with musculoskeletal disorders in physical therapy practice

BACKGROUND

Differential diagnosis is a hot topic in physical therapy, especially for those working in a direct access setting dealing with neck pain and its associated disorders. All international guidelines agree in recommending to first rule out non-musculoskeletal pathologies as the cause of signs and symptoms in the patient. Although the autonomic nervous system (ANS) has a crucial role and is also involved in pain conditions, coverage of it in neuroscience textbooks and educational programmes is limited and most healthcare professionals are unfamiliar with it. Although autonomic conditions are benign in nature, they are clinically of great importance as they may be a 'red flag' warning of an injury along the sympathetic pathway. Therefore, sound knowledge of the ANS system is essential for clinicians.

OBJECTIVE

To develop physical therapists' knowledge of and confidence in understanding cervical ANS function and dysfunction, thus enhancing clinical reasoning skills and the pattern recognition process, and performing and interpreting objective examinations.

METHODS

This master class provides an introductory guide and essential knowledge to facilitate clinicians to understand cervical autonomic dysfunctions and their clinical evaluation. The optimal referral method is also handled.

CONCLUSIONS

Gaining knowledge and understanding of the ANS, its function, its dysfunction, and the related clinical manifestations is likely to lead to a decision-making process driven by 'science and conscience'. This will empower physical therapists to be aware of subtle clues that may be offered by patients during the interview and history intake leading to the appropriate physical examination and triage.

Spontaneous spleen rupture mimicking non-specific thoracic pain: A rare case in physiotherapy practice

BACKGROUND

The prevalence of Thoracic Pain (TP) is estimated to be low compared to other common musculoskeletal disorders such as nonspecific low back pain (LBP). Notably, compared to LBP, TP or referral pain to the thoracic area potentially may involve serious pathologies. Visceral referral of pain may present to the thoracic spine or anteriorly in the abdomen or chest. Rupture of the spleen in the absence of trauma or previously diagnosed disease is rare and rarely documented in emergency medicine literature. The incidence of red flags are higher in the thoracic area in comparison to the lumbar or cervical regions, but TP can also be of musculoskeletal origin and for this reason it is important to assess the origin of pain.

CASE DESCRIPTION

This case report describes the clinical history, evaluation and management of a 60-year-old complaining of upper thoracic, bilateral shoulder, and right upper quadrant abdominal pain. The patient's clinical findings from a physiotherapist's assessment led to a referral to a physician to explore a potential non-musculoskeletal origin. A splenectomy was required due to a non-traumatic rupture of the spleen. After 20 days of hospitalization from the surgery, the patient returned to all normal activities of daily living.

DISCUSSION AND CONCLUSION

The purpose of this current case report is to describe the clinical reasoning of a physiotherapist screening a patient who presented with thoracic pain due to a spontaneous rupture of the spleen, that resulted in a referral to another health practitioner.

Improving Adherence to a Home Rehabilitation Plan for Chronic Neck Pain through Immersive Virtual Reality: A Case Report

Idiopathic chronic neck pain is a highly disabling musculoskeletal condition. Immersive virtual reality shows a promising efficacy in the treatment of chronic cervical pain through the mechanism of distraction from the pain. This case report describes the management of C.F., a fifty-seven-year-old woman, who suffered from neck pain for fifteen months. She had already undergone a cycle of physiotherapy treatments including education, manual therapy, and exercises, following international guidelines. The patient's poor compliance did not allow adherence to the exercise's prescription. Home exercise training through virtual reality was therefore proposed to the patient to improve her adherence to the treatment plan. The personalization of the treatment allowed the patient to resolve in a short time period her problem and return to live with her family peacefully.

Efficacy of Peripheral Nerve Stimulation with a High Frequency Electromagnetic Coupled (HF-EMC) Powered Implanted Receiver in Treating Different Pain Targets/Neuralgias

Introduction

Chronic pain is a significant global public health problem. Peripheral nerve stimulation (PNS) has been gaining popularity in recent years as it is effective, safe and less invasive than surgery for the treatment of chronic pain. The authors aimed to document and share a collection of patient-reported pain scores before and after implanting a percutaneous PNS lead/s with an external wireless generator at various target nerves.

Methods

The authors designed a retrospective study, reviewing electronic medical records. Statistical analysis was performed using SPSS 26; p-value ≤ 0.05 was considered significant.

Results

The mean baseline pain scores of 57 patients have reduced significantly after the procedure at different follow-up durations. Target nerves included genicular nerves, superior cluneal nerves, posterior tibial nerve ± sural nerve, middle cluneal nerves, radial and ulnar nerves and right common peroneal nerve. In the one-month follow-up group, mean pain score was reduced from 7.44 ± 1.48 pre-procedure to 1.6 ± 1.49, from 7.42 ± 1.5 pre-procedure to 1.6 ± 1.5 7.42 at 3 months, from 7.52 ± 1.5 to 1.72 ± 1.57 at 6 months, from 7.41 ± 1.53 to 1.7 ± 1.55 at 9 months, from 7.41 ± 1.58 to 1.76 ± 1.63 at 12 months, from 7.38 ± 1.59 to 1.69 ± 1.56 at 15 months and from 7.5 ± 1.7 to 1.45 ± 1.57 at 24 months (p ≤ 0.001). Patients also reported significant reduction in morphine milliequivalent, pre-procedure MME 47.75 ± 452.5 to 37.92 ± 43.51 at 6 months (p = 0.002, N = 57), pre-procedure MME 42.72 ± 43.19 to 30.38 ± 41.62 at 12 months (p = 0.003, N = 42), and pre-procedure MME 41.2 ± 46.12 to 21.19 ± 40.88 at 24 months (p ≤ 0.001, N = 27). The only complications occurred post procedure with 2 patients receiving an explant and 1 patient receiving a lead migration.

Conclusion

PNS has been shown to be safe and effective in treating chronic pain at different sites with sustained pain relief for up to 24 months. This study is unique in providing long-term follow-up data.

What to Look Out for, What to Do, and When: 3 Key Messages for Safely Treating Neck Pain, Headache, and/or Orofacial Symptoms in Musculoskeletal Rehabilitation Settings

SYNOPSIS: Neck pain, headache, and/or orofacial symptoms are potentially the first (nonischemic) symptoms of an underlying vascular pathology or blood flow limitation. If an underlying vascular pathology or blood flow limitation is not recognized by the musculoskeletal rehabilitation clinician, it can subsequently be aggravated by treatment, raising the risk of serious adverse events. We argue that clinicians can make an important, and potentially lifesaving, difference by providing specific information and advice. This is especially the case in patients with an intermediate level of concern, for example, in patients who only show a few concerning features regarding a possible underlying serious condition and for whom an initial vasculogenic hypothesis was rejected during the clinical reasoning process. We present background information to help the reader understand the context of the problem and suggestions for how clinicians can provide appropriate information and advice to patients who present with neck pain, headache, and/or orofacial symptoms.

Presentation and physical therapy management of upper cervical instability in patients with symptomatic generalized joint hypermobility: International expert consensus recommendations

Experts in symptomatic generalized joint hypermobility (S-GJH) agree that upper cervical instability (UCI) needs to be better recognized in S-GJH, which commonly presents in the clinic as generalized hypermobility spectrum disorder and hypermobile Ehlers-Danlos syndrome. While mild UCI may be common, it can still be impactful; though considerably less common, severe UCI can potentially be debilitating. UCI includes both atlanto-occipital and atlantoaxial instability. In the absence of research or published literature describing validated tests or prediction rules, it is not clear what signs and symptoms are most important for diagnosis of UCI. Similarly, healthcare providers lack agreed-upon ways to screen and classify different types or severity of UCI and how to manage UCI in this population. Consequently, recognition and management of UCI in this population has likely been inconsistent and not based on the knowledge and skills of the most experienced clinicians. The current work represents efforts of an international team of physical/physiotherapy clinicians and a S-GJH expert rheumatologist to develop expert consensus recommendations for screening, assessing, and managing patients with UCI associated with S-GJH. Hopefully these recommendations can improve overall recognition and care for this population by combining expertise from physical/physiotherapy clinicians and researchers spanning three continents. These recommendations may also stimulate more research into recognition and conservative care for this complex condition.

Neoplastic malignant cord compression mimicking low back pain: A case report

BACKGROUND

The point prevalence of Cauda Equina Syndrome (CES) as a cause of Low Back Pain (LBP) is estimated at 0.04% in primary care, and it is reported as a complication in about 2% of patients with disc herniation. Compression of the cauda equina usually occurs as a result of disc prolapse. However, CES may be caused by any space-occupying lesion, including spinal stenosis, neoplasms, cysts, infection, and osteophytes. First contact physiotherapists may encounter patients with early CES, as the clinical presentation of CES can mimic non-specific LBP.

CASE PRESENTATION

This case report presents the medical history, diagnostic tests and relevant clinical data of a 52-year-old man complaining of LBP. The patient's medical history, his symptoms and the clinical findings led to the identification of a number of red flags (i.e. risk factors) suggestive of a non-musculoskeletal condition. The patient was referred to the emergency department for further investigation. Having undergone several diagnostic tests, the patient was diagnosed with CES due to malignancy.

CONCLUSIONS

This case report highlights the importance of differential screening throughout the treatment period, in order to identify red flags that warrant further investigation and a referral to an appropriate specialist. Physiotherapy screening should include clinical reasoning, careful analysis of clinical presentation and symptom progression, in addition to appropriate referral for medical assessment and diagnostic imaging, if necessary.

Bacteria in human lumbar discs - subclinical infection or contamination? Metabolomic evidence for colonization, multiplication, and cell-cell cross-talk of bacteria

BACKGROUND CONTEXT

The accumulating evidence associating sub-clinical infection with disc degeneration (DD) and the controversy of contamination versus infection mandates a further understanding of the microbial activity in the disc and host-microbiome interaction.

PURPOSE

To utilize a novel approach of metabolomics to probe the presence of bacterial metabolites involved in colonization, survival, and replication in human lumbar intervertebral discs (LIVD).

STUDY DESIGN

An observational case-control study.

PATIENT SAMPLE

Nucleus pulposus from the LIVD of three brain-dead voluntary organ donors (MRI normal and classified as controls) and of three patients undergoing surgery for disc degeneration (DD) (cases) were utilized.

METHODS

Untargeted metabolite profiling was carried out in six discs (3-controls and 3-cases) after extraction using methanol: acetonitrile: water (2:2:1) solvent system and acquired through HPLC-MS/MS platform using C18 reversed-phase column. From the total IVD metabolome, microbial metabolites were filtered by mapping against HMDB, ChEBI, SigMol, Siderophore database, ecdmb database, and PaMet databases. The biological functions of the metabolites were then studied by MSEA pipeline from Metaboanalyst, and the enrichment ratio, p-value, and Variably Importance Projection scores of the metabolites were calculated. Degeneration responsive changes in the abundance of the microbial metabolites were calculated based on the peak intensities between the control and cases.

RESULTS

Mass spectrometry identified a total of 17601 and 15003 metabolites, respectively, in the control and degenerated discs. Preliminary mapping of the above metabolites against HMDB indicated the multiple sources, and of these, 64 metabolites were of microbial origin, accounting for 1.6% of the total IVD metabolome. Principle Component Analysis and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA) showed distinct clustered patterns between control and disc degene`ration, indicating a strong variation in concentration, peak, and spectral values of the 64 metabolites between controls and cases. After the exclusion of metabolites that were also associated with humans, drugs, and food, 39 metabolites specific to bacteria were isolated. Nine were primary metabolites related to bacterial growth and survival, and the remaining 30 were secondary metabolites related to different environmental stress response activities. The three significant pathways (p<.001) which were predominant in the bacterial metabolites were autoinducer-2 biosynthesis, peptidoglycan biosynthesis, and chorismate pathway. In addition, a significant fold change of >1.0 was found for nine metabolites which included (S)-14-Methyilhexadecanoic acid related to P. acnes, 9-OxoODE, and 13-OxoODE related to gut flora, vibriobactin - a siderophore, tuberculosinol and iso-tuberculosinol, virulence factors of M. tuberculosis. There was also upregulation of Autoinducer- 2, an important "Quorum sensing molecule" involved in bacterial cross-talk.

CONCLUSION

We identified several bacterial-specific metabolites participating in bacterial growth, survival, and cross-talk pathways. These were found in both groups but up-regulated in degenerated discs. The presence of Quorum sensing molecules and cell-cell interactions provides firm proof of colonization and growth. These findings indicate that the bacterial presence may not be mere contamination but could be colonization with a possible role in infection-mediated inflammation in DD.

CLINICAL SIGNIFICANCE

Proof of subclinical infection as an initiator of DD and documentation of exact germ and drug sensitivity will change the way millions of patients with non-specific low back pain (NSLBP) are treated across the world.
