Importance of psychological factors for the recovery from a first episode of acute non-specific neck pain - a longitudinal observational study

Adaption and psychometric evaluation of the Hindi version of Neck Disability Index in the rural population of Northern India: A cross cultural study

Background

To ensure the validity and therapeutic utility of the Neck disability index (NDI) scale, translations, cultural adaptations and psychometric evidence is necessary. This study aimed to address the absence of a suitable and validated Hindi version of the NDI for the rural population. The specific objectives were to translate, adapt, and evaluate the psychometric properties of the newly developed Hindi version of the NDI.

Methods

Following guidelines provided by the American Association of Orthopedic Surgeons, the original English NDI scale was cross-culturally adapted into Hindi. The adaptation process included translations (forward and backward), expert committee review, pre-testing and cognitive debriefing with 30 individuals experiencing chronic non-specific neck pain. The outcome of this process was the creation of the Hindi version of the NDI, termed NDI-Hi. Subsequently, NDI-Hi was administered to 211 participants with neck pain from multiple centers for psychometric testing. The evaluation involved test-retest reliability over a 48-hour interval, factor analysis, assessment of internal reliability measures, and criterion-related validity by comparing it with the NPAD-Hindi version.

Results

The NDI-Hi version exhibited favorable psychometric properties, including good test-retest reliability with an intra-class correlation coefficient (ICC) of 0.87. Internal consistency of the scale was high, indicated by Cronbach's alpha coefficient (α) of 0.96. The standard error of measurement (SEM) was determined to be 2.58, and the minimal detectable change (MDC) was calculated to be 7.15. Furthermore, the NDI-Hi showed significant correlation with the NPAD-Hindi version, with a correlation coefficient (rho) of 0.86, and a p-value of less than 0.001.

Conclusions

The NDI-Hi demonstrated validity and reliability as an outcome tool for assessing neck disability. It can be effectively utilized in clinical practice and research settings involving Hindi-speaking individuals with chronic non-specific neck pain. The adapted scale is particularly well-suited for the rural Northern Indian Hindi-speaking population.

Systemic Inflammation, Sleep, and Psychological Factors Determine Recovery Trajectories for People With Neck Pain: An Exploratory Study

We conducted an explorative prospective cohort study with 6 months follow-up to 1) identify different pain and disability trajectories following an episode of acute neck pain, and 2) assess whether neuroimmune/endocrine, psychological, behavioral, nociceptive processing, clinical outcome, demographic and management-related factors differ between these trajectories. Fifty people with acute neck pain (ie, within 2 weeks of onset) were included. At baseline, and at 2, 4, 6, 12, and 26 weeks follow-up, various neuroimmune/endocrine (eg, inflammatory cytokines and endocrine factors), psychological (eg, stress symptoms), behavioral (eg, sleep disturbances), nociceptive processing (eg, condition pain modulation), clinical outcome (eg, trauma), demographic factors (eg, age), and management-related factors (eg, treatment received) were assessed. Latent class models were performed to identify outcome trajectories for neck pain and disability. Linear mixed models or the Pearson chi-square test were used to evaluate differences in these factors between the trajectories at baseline and at each follow-up assessment and over the entire 6 months period. For pain, 3 trajectories were identified. The majority of patients were assigned to the "Moderate pain - Favourable recovery" trajectory (n = 25; 50%) with smaller proportions assigned to the "Severe pain - Favourable recovery" (n = 16; 32%) and the "Severe pain - Unfavourable recovery" (n = 9; 18%) trajectories. For disability, 2 trajectories were identified: "Mild disability - Favourable recovery" (n = 43; 82%) and "Severe disability - Unfavourable recovery" (n = 7; 18%). Ongoing systemic inflammation (increased high-sensitive C-reactive protein), sleep disturbances, and elevated psychological factors (such as depression, stress and anxiety symptoms) were mainly present in the unfavorable outcome trajectories compared to the favorable outcome trajectories. PERSPECTIVE: Using exploratory analyses, different recovery trajectories for acute neck pain were identified based on disability and pain intensity. These trajectories were influenced by systemic inflammation, sleep disturbances, and psychological factors.

Active behavioural physiotherapy intervention for acute non-specific neck pain: a cluster randomised double-blind pilot and feasibility clinical trial

PURPOSE

To evaluate the feasibility of an active behavioural physiotherapy intervention (ABPI) and procedures to prevent the transition to chronicity in patients with acute non-specific neck pain (ANSNP).

MATERIALS AND METHODS

A cluster-randomised double-blind (assessors and participants), parallel 2-arm (ABPI versus standard physiotherapy intervention [SPI]) pilot and feasibility clinical trial was conducted owing to a pre-specified published protocol. Six public hospitals were recruited and cluster-randomised (computer-generated randomisation with block sampling). Sixty participants (30 in each arm, 10 per hospital) were assessed at baseline and 3 months following baseline for neck disability index, numerical pain rating scale, cervical range-of-motion, fear-avoidance beliefs questionnaire and EuroQol 5-dimension 5-level.

RESULTS

All procedures worked well. The participants' median age was 36.5 (range 21-59, interquartile range: 20.75) years. Participants in the ABPI demonstrated better improvement in all outcomes compared to SPI. Furthermore, the number of fully recovered participants following ABPI (27/30, 90.00%) was higher than SPI (16/30, 53.33%) with fewer treatment sessions and lower costs of management.

CONCLUSIONS

The findings suggest that the ABPI is feasible and valuable (e.g. a high number of fully recovered participants, fewer treatment sessions and reduced management costs compared to the SPI) in conducting a future definitive trial to evaluate the effectiveness of the ANSNP management.

Predicting chronic postsurgical pain: current evidence and a novel program to develop predictive biomarker signatures

ABSTRACT

Chronic pain affects more than 50 million Americans. Treatments remain inadequate, in large part, because the pathophysiological mechanisms underlying the development of chronic pain remain poorly understood. Pain biomarkers could potentially identify and measure biological pathways and phenotypical expressions that are altered by pain, provide insight into biological treatment targets, and help identify at-risk patients who might benefit from early intervention. Biomarkers are used to diagnose, track, and treat other diseases, but no validated clinical biomarkers exist yet for chronic pain. To address this problem, the National Institutes of Health Common Fund launched the Acute to Chronic Pain Signatures (A2CPS) program to evaluate candidate biomarkers, develop them into biosignatures, and discover novel biomarkers for chronification of pain after surgery. This article discusses candidate biomarkers identified by A2CPS for evaluation, including genomic, proteomic, metabolomic, lipidomic, neuroimaging, psychophysical, psychological, and behavioral measures. Acute to Chronic Pain Signatures will provide the most comprehensive investigation of biomarkers for the transition to chronic postsurgical pain undertaken to date. Data and analytic resources generatedby A2CPS will be shared with the scientific community in hopes that other investigators will extract valuable insights beyond A2CPS's initial findings. This article will review the identified biomarkers and rationale for including them, the current state of the science on biomarkers of the transition from acute to chronic pain, gaps in the literature, and how A2CPS will address these gaps.

Factors Associated With Pain Medication Use and the Relationship to Chiropractic Treatment Outcomes for Patients With Low Back and Neck Pain: A Cross-Sectional Study

OBJECTIVE

The study objectives were to identify baseline factors associated with pain medication use and determine any differences in chiropractic treatment outcomes in patients with low back pain (LBP) and neck pain (NP) depending on their use of pain medication.

METHODS

This cross-sectional, prospective outcomes study included 1077 adults with acute or chronic LBP and 845 adults with acute or chronic NP recruited from Swiss chiropractors in their offices within 4 years. Demographic data and the responses to the Patient's Global Impression of Change scale collected at 1 week, 1 month, 3 months, 6 months, and 1 year were analyzed with the χ2 test. Baseline pain and disability levels were measured using the numeric rating scale (NRS), Oswestry questionnaire for LBP, and Bournemouth questionnaire for patients with NP and analyzed with the Mann-Whitney U test between the 2 groups. To detect significant predictors of medication use at baseline, logistic regression analysis was performed.

RESULTS

Patients with acute LBP and NP were more likely than those with chronic pain to take pain medication (P < .001 LBP; P = .003 NP). Medication use was more likely with patients with radiculopathy (P < .001 LBP; P = .05 NP) who were smokers (P = .008 LBP; P = .024 NP) and those reporting below-average general health (P < .001 LBP and NP). Pain medication users had higher baseline pain (P < .001 LBP and NP) and disability (P < .001 LBP and NP) scores.

CONCLUSION

Patients with LBP and NP had significantly higher pain and disability levels at baseline, tended to have radiculopathy and poor health, were smokers, and presented during the acute phase. However, for this sample of patients, there were no differences in subjective improvement between users and non-users of pain medication for any data collection time point, which has management implications.

Negative Psychological Factors' Influence on Delayed Onset Muscle Soreness Intensity, Reduced Cervical Function and Daily Activities in Healthy Participants

We examined the influence of negative psychological factors (catastrophizing, distress and kinesiophobia) on delayed onset muscle soreness (DOMS) intensity, cervical function (strength and range of motion) and on daily activities (ADL), and the suitability of an exercise protocol designed to induce DOMS within the cervical region. Psychological factors and cervical function were assessed in 86 healthy participants at baseline before applying a DOMS provocation protocol in the cervical flexor muscles. After 24hour, cervical function was reassessed. In addition, at 24hour and 48hour, the intensity of DOMS and its impact on ADL were assessed using the visual analog scale (VAS). The protocol was effective given that it generated low-moderate intensity DOMS (VAS≈30 -40mm) and a statistically significant reduction in cervical strength and range of motion. Psychological distress (anxiety and depression), but not kinesiophobia and catastrophism, predicted a loss of cervical strength (explained 43% of the variance) and range of motion (explained 22% of the variance) after induction of DOMS. In addition, participants' anxiety level predicted DOMS intensity at 24hour (explained 19% of the variance). PERSPECTIVE: The present findings highlight the relevance of evaluating psychological distress as a preventive/therapeutic measure, given that high levels of distress could lead to more intense and disabling pain in acute injuries, and all these aspects are considered risk factors for the chronification of symptoms.

Multi-Site Observational Study to Assess Biomarkers for Susceptibility or Resilience to Chronic Pain: The Acute to Chronic Pain Signatures (A2CPS) Study Protocol

Chronic pain has become a global health problem contributing to years lived with disability and reduced quality of life. Advances in the clinical management of chronic pain have been limited due to incomplete understanding of the multiple risk factors and molecular mechanisms that contribute to the development of chronic pain. The Acute to Chronic Pain Signatures (A2CPS) Program aims to characterize the predictive nature of biomarkers (brain imaging, high-throughput molecular screening techniques, or "omics," quantitative sensory testing, patient-reported outcome assessments and functional assessments) to identify individuals who will develop chronic pain following surgical intervention. The A2CPS is a multisite observational study investigating biomarkers and collective biosignatures (a combination of several individual biomarkers) that predict susceptibility or resilience to the development of chronic pain following knee arthroplasty and thoracic surgery. This manuscript provides an overview of data collection methods and procedures designed to standardize data collection across multiple clinical sites and institutions. Pain-related biomarkers are evaluated before surgery and up to 3 months after surgery for use as predictors of patient reported outcomes 6 months after surgery. The dataset from this prospective observational study will be available for researchers internal and external to the A2CPS Consortium to advance understanding of the transition from acute to chronic postsurgical pain.

Limited prognostic value of pain duration in non-specific neck pain patients seeking chiropractic care

BACKGROUND

Pain chronicity is considered an important prognostic factor for outcome. Here, it was investigated whether pain duration influences outcome when only chronic patients (pain > three months) are considered. Secondary aims were to determine, in patients of any pain duration, how much variance in outcome is explained by pain duration and whether pain duration truly predicts outcomes, i.e. out-of-sample prediction in independent data.

METHODS

Secondary analysis of a cohort study of neck pain patients. Patients were assessed before start of treatment and at one week, one, three, six- and 12-months follow-up. Outcomes were Patient Global Impression of Change (PGIC) and percent change of patients' perceived pain intensity, rated on a numerical rating scale (NRS). Regression analyses (linear and logistic) and supervised machine learning were used to test the influence of pain duration on PGIC and percent NRS change at one week, one, three, six- and 12-months follow-up within sample and out-of-sample. Separate analyses were performed for the full sample (n=720) and for chronic patients (n=238) only.

RESULTS

No relationship between pain duration and outcome was found for chronic patients only. For the full sample, statistical relationships between pain duration and outcomes were observed at all tested follow-up time points. However, the amount of variance in outcome explained by pain duration was low and no out-of-sample prediction was possible.

CONCLUSIONS

Pain duration did not emerge as an important predictor of outcome in this database of 720 neck pain patients receiving chiropractic treatment.

Efficacy of manual therapy on psychological status and pain in patients with neck pain. A randomized clinical trial

Objectives:

To compare the effectiveness of Maitland versus Mulligan mobilization techniques on pain, functional disability, and psychological status in patients with neck pain.

Methods:

Forty-four patients with nonspecific neck pain were randomly assigned to the Maitland group (n=22 patients received Maitland therapy [central or unilateral postero-anterior pressure] for 2 sessions/week for 3 weeks) and Mulligan group (n=22 patients received Mulligan sustained natural apophyseal glides for 2 sessions/week for 3 weeks). This study was conducted at the Rehabilitation Clinic, King Abdulaziz Hospital, Jeddah, Kingdom of Saudi Arabia between December 2016 to May 2017. The outcome measures were the numeric pain rating scale score, neck disability index score, beck depression inventory score, State-trait anxiety inventory score, fear avoidance beliefs questionnaire, and pain catastrophic scale results. The independent t-test, Shapiro-Wilk test, and paired t-test were used in data analysis.

Results:

There were significant improvements in mean values of the numeric pain rating scale, neck disability index, beck depression inventory, state-trait anxiety inventory scores, and pain catastrophic scale results after the interventions in both groups (p<0.05, all except fear avoidance beliefs results in mulligan group p>0.05), and there were no significant differences in mean values between the groups (p>0.05).

Conclusion:

In patients with nonspecific neck pain, Maitland and Mulligan mobilization techniques have positive effects on neck pain, functional disability, and selected psychological features with no significant difference between them.

Effect of Neural Mobilization on Nerve-Related Neck and Arm Pain: A Randomized Controlled Trial

Purpose: Neural mobilization (NM) is often used to treat nerve-related conditions, and its use is reasonable with nerve-related neck and arm pain (NNAP). The aims of this study were to establish the effect of NM on the pain, function, and quality of life (QOL) of patients with NNAP and to establish whether high catastrophizing and neuropathic pain influence treatment outcomes. Method: A randomized controlled trial compared a usual-care (UC; n = 26) group, who received cervical and thoracic mobilization, exercises, and advice, with an intervention (UCNM; n = 60) group, who received the same treatment but with the addition of NM. Soft tissue mobilization along the tract of the nerve was used as the NM technique. The primary outcomes were pain intensity (rated on the Numerical Pain Rating Scale), function (Patient-Specific Functional Scale), and QOL (EuroQol-5D) at 3 weeks, 6 weeks, 6 months, and 12 months. The secondary outcomes were the presence of neuropathic pain (using the Neuropathic Diagnostic Questionnaire) and catastrophizing (Pain Catastrophising Scale). Results: Both groups improved in terms of pain, function, and QOL over the 12-month period (p < 0.05). No between-groups differences were found at 12 months, but the UCNM group had significantly less pain at 6 months (p = 0.03). Patients who still presented with neuropathic pain (p < 0.001) and high pain catastrophizing (p = 0.02) at 6- and 12-mo follow-ups had more pain. Conclusions: Both groups had similar improvements in function and QOL at 12-month follow-up. The UCNM group had significantly less pain at 6-month follow-up and a lower mean pain rating at 12-month follow-up, although the difference between groups was not significant. Neuropathic pain is common among this population and, where it persisted, patients had more pain and functional limitations at 12-mo follow-up.

Translation, cross-cultural adaptation and psychometric evaluation of the Thai version of the fear-avoidance beliefs questionnaire in patients with non-specific neck pain

OBJECTIVES

Fear-avoidance beliefs questionnaire (FABQ) is a self-report, valid and reliable questionnaire to quantify fear and avoidance beliefs related to physical activity and work. Furthermore, it can be used to predict prolong disability in patients with non-specific neck pain. Although it was originally developed to manage patients with low back pain, it has also been studied in individuals with neck pain. This questionnaire was translated into several languages following reports of potential benefits in patients with neck pain. Recently, Thai neck clinical trials, international multi-centre trials and data sharing are growing throughout the world but no validated Thai version of the FABQ is available for clinical and research uses. Our objectives were to translate and cross-culturally adapt the FABQ into Thai version and evaluate its psychometric properties in Thai patients with non-specific neck pain.

METHODS

Cross-cultural translation and adaptation of the FABQ were conducted according to standard guidelines. A total of 129 participants with non-specific neck pain were invited to complete the Thai versions of the FABQ (FABQ-TH), neck disability index and visual analogue scale for pain intensity. Psychometric evaluation included exploratory factor analysis, internal consistency, test-retest reliability, agreement, and convergent validity. Thirty participants completed the FABQ-TH twice with a 48-h interval between tests to assess the test-retest reliability.

RESULTS

Factor analysis identified four components for the FABQ-TH (66.69% of the total variance). The intraclass correlation coefficient of test-retest reliability was excellent for the total score (0.986), work attitudes (0.995), physical activity attitudes (0.958), physical activity experiences (0.927), and expected recovery (0.984). Cronbach's alpha for internal consistency was excellent (range 0.87-0.88) for all items. The minimal detectable change of the FABQ-TH was 5.85. The FABQ-TH correlated to its subscales (range 0.470-0.936), indicating the strongest association with work attitude. The weakest correlation was observed between the FABQ-TH and disability (r _s =0.206, p=0.01). Missing data and significant floor or ceiling effects were not found.

CONCLUSIONS

The Thai version of the FABQ for non-specific neck pain was successfully adapted. It is a valid and reliable instrument to quantify fear and avoidance beliefs among patients with non-specific neck pain who speak and read Thai.

Chronic neck pain and depression: the mediating role of sleep quality and exercise

Previous researches have found that chronic neck pain was closely related to depression. However, the relation between chronic neck pain, sleep quality, exercise and depression remains unclear. This study aims to evaluate the association between these factors, based on the assumption that sleep quality and exercise are potential mediators in the relationship between chronic neck pain and depression. This cross-sectional study enrolled 231 patients with chronic neck pain who were referred to outpatient clinics in department of neurology between July and December 2016. Data analysis was performed using a structural equation model to evaluate the mediating effects of sleep quality and exercise frequency on the relation between chronic neck pain intensity and depression. A positive correlation between neck pain intensity and depression was unveiled. In addition, sleep quality was identified as a significant positive mediator between neck pain intensity and depression, and exercise can help relieve depression. Poor sleep quality leads to an increase of the symptoms of depression for people with high neck pain intensity which can be effectively relieved via additional exercise.

Pragmatic cluster randomised double-blind pilot and feasibility trial of an active behavioural physiotherapy intervention for acute non-specific neck pain: a mixed-methods protocol

INTRODUCTION

Non-specific neck pain causes pain and disability and contributes substantial socioeconomic burden internationally. Up to 50% of adults experience neck pain annually, leading to reduced the quality of life. An active behavioural physiotherapy intervention (ABPI) may be feasible to manage patients with acute non-specific neck pain to prevent transition to chronicity. A recent pilot and feasibility trial investigating an acute whiplash-associated disorder population found potential value of the ABPI with 95% of participants fully recovered (Neck Disability Index: NDI ≤4, compared with 17% in the standard physiotherapy arm); supporting a definitive trial. Qualitative findings from the physiotherapists supported the potential of the ABPI in a non-specific neck pain population.

METHODS AND ANALYSIS

Two phases: (1) Pragmatic cluster randomised double-blind, parallel 2-arm (ABPI vs standard physiotherapy intervention) pilot and feasibility trial to evaluate the procedures and feasibility of the ABPI for the management of acute non-specific neck pain. Six physiotherapy departments from six public hospitals in Thailand will be recruited and cluster randomised by a computer-generated randomisation sequence with block sampling. Sixty participants (30 each arm, 10 per hospital) will be assessed at baseline and 3 months following baseline for NDI, Numerical Rating Scale for pain intensity, cervical range of motion, fear-avoidance beliefs questionnaire and EuroQol-5 dimensions 5 levels outcomes, and (2) Embedded qualitative study using semistructured interviews to explore acceptability of the ABPI to participants (n=12) and physiotherapists (n=3). Descriptive analysis of the quantitative data and interpretative phenomenological analysis to code and analyse qualitative data (deductive and inductive) will inform feasibility for a future definitive trial.

ETHICS AND DISSEMINATION

This trial is approved by the Naresuan University Institutional Review Board (NUIRB_0380/61).

Neck pain in South Africa: An overview of the prevalence, assessment and management for the contemporary clinician

BACKGROUND

Neck pain is a prevalent condition and is associated with high levels of disability and pain. The long-term prognosis can be poor, and therefore effective management in the acute stage is important.

OBJECTIVES

To provide an overview of the prevalence of neck pain and physiotherapy management and to provide evidence-informed recommendations for clinical practice within a South African context.

METHOD

The literature was reviewed considering prevalence, risk factors and examination. Management recommendations were derived from the highest levels of evidence of clinical practice guidelines, systematic reviews and randomised clinical trials.

RESULTS

Neck pain is classified into four grades, and three trajectories of recovery have been identified. Although the incidence of neck pain globally is high, in the South African context the majority of the population have limited access to physiotherapy management. Sound clinical reasoning is important in the assessment and decision-making process for management. Exercise, and mobilisation or manipulation are effective treatment options in the management of most types of neck pain. Other physical modalities such as needling, transcutaneous electrical nerve stimulation, laser and intermittent traction may be used as an adjunct to management.

CONCLUSION

The burden of neck pain globally is high; however, there is a lack of information on current practice, prevalence and burden of neck pain in the South African context. Sound evidence-informed clinical reasoning to inform a working diagnosis and to enable patient-centred management is important.

CLINICAL IMPLICATIONS

A thorough assessment is essential to gather information to formulate hypotheses regarding diagnosis and prognosis for neck pain. Exercise, and mobilisation or manipulation are effective management options.

Measuring biopsychosocial risk for back pain disability in chiropractic patients using the STarT back screening tool: a cross-sectional survey

Background

The Keele STarT Back Screening Tool (SBT), a 9-item questionnaire, screens for pain, physical functioning, fear-avoidance beliefs, catastrophizing, anxious thoughts, low mood, and bothersomeness in persons with back pain. SBT scores designate low, medium, or high risk for developing persistent disabling back pain. The primary study aim was to report the prevalence of SBT-calculated risk for back pain disability in US patients seeking chiropractic care.

Methods

The SBT questionnaire was administered to patients ≥18 years in 3 Chiropractic College outpatient teaching clinics in Iowa and Illinois (May 2017). Descriptive statistics were used to analyze respondent characteristics and prevalence of SBT-calculated risk subgroups. Binary logistic regression analysis was used to examine the relationship between respondent characteristics and SBT scores (including psychological subscores).

Results

Of 550 respondents, 496 completed the SBT; 392 (79%) scored low-risk, 81 (16%) medium-risk, and 23 (5%) high-risk. Mean (SD) age was 44.8 (15.9), 56.9% were female, 88.2% white, 62.6% employed, mean current pain was 2.9 (2.1) out of 10, and 62% reported symptom duration > 3 months. Eighteen percent of respondents reported anxious thoughts, 32% low mood, 41% ≥ 1 and 21% ≥ 3 SBT psychological risk factors. Respondents reporting higher average pain (OR = 1.8 [1.4, 2.3]) and pain severity (OR = 1.3 [1.0 to 1.6]) were more likely to score with medium or high risk. Respondents reporting mid back versus low back pain (OR = 0.2 [0.1, 0.7]), and those employed less than full-time versus full-time (0.2 [01, 0.5]) were less likely to score with medium or high risk. Respondents reporting higher average pain were more likely to report ≥1 psychological factor (OR = 1.8 [1.5, 2.0]). Respondents employed part-time were less likely to report ≥1 psychological factor than those employed full-time (OR = 0.4 [0.2, 0.7]).

Conclusion

The sample surveyed was less likely to score with medium or high risk for back pain disability than previous samples studied, perhaps due to differences in study design and sample characteristics. Rates of low mood and anxious thoughts indicate a need for future research to explore psychological factors among persons seeking chiropractic care.
