RESUMEN
PURPOSE: To assess the test-retest and inter-rater reliability of goniometry and fleximetry in measuring cervical range of motion in individuals with chronic neck pain. METHODS: A reliability study. Thirty individuals with chronic neck pain were selected. Cervical range of motion was measured by goniometry and fleximetry at two time points 7 days apart. To characterize the sample, we used the numerical pain rating scale, Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimum detectable change (MDC) were calculated. Correlations between goniometry and fleximetry measurements were performed using Spearman's correlation coefficient (rho). RESULTS: For goniometry, we found excellent test-retest reliability (ICC ≥ 0.986, SEM ≤ 1.89%, MDC ≤ 5.23%) and inter-rater reliability (ICC ≥ 0.947, SEM ≤ 3.91%, MDC ≤ 10.84%). Similarly, we found excellent test-retest reliability (ICC ≥ 0.969, SEM ≤ 2.71%, MDC ≤ 7.52%) and inter-rater reliability (ICC ≥ 0.981, SEM ≤ 1.88%, MDC ≤ 5.20%) for fleximetry. Finally, we observed a strong correlation between the goniometry and the fleximetry for all cervical movements (rho ≥ 0.993). CONCLUSION: Goniometry and fleximetry measurements are reliable for assessing cervical range of motion in individuals with chronic neck pain.

BACKGROUND: Neck pain is a prevalent global musculoskeletal issue, significantly contributing to the loss of years of healthy life due to disability. Chronic nonspecific neck pain (CNNP) involves diverse symptoms impacting mobility and quality of life. While therapeutic exercises demonstrate efficacy, the role of photobiomodulation therapy (PBMT) remains uncertain. This study aims to assess the additional effects of PBMT within a multimodal therapeutic intervention for CNNP. METHODS: A randomized, two-arm, controlled, blind clinical trial follows CONSORT and SPIRIT guidelines. Participants diagnosed with CNNP will receive a stand-alone multimodal therapeutic intervention or the same program with additional PBMT. The primary outcomes will be assessed by the functional disability identified through applying the NDI (Neck Disability Index). Secondary outcomes will be pain intensity during rest and active neck movement, catastrophizing and kinesiophobia, functionality, and disability assessed at baseline, after 8 weeks, and at a 4-week follow-up. Both groups receive pain education before personalized interventions, including resistance exercises, neuromuscular activities, mobility, and body balance. The PBMT group undergoes low-level light therapy. Intention-to-treat analysis, using linear mixed models, employs data presented as mean, standard deviation, and differences with a 95% confidence interval. Non-normally distributed variables transform. Statistical significance is set at 5%. DISCUSSION: This study addresses a critical gap in understanding the combined effects of PBMT and therapeutic exercises for CNNP. The findings aim to guide clinicians, researchers, and CNNP sufferers through rigorous methodology and diverse outcome assessments, offering valuable insights into evidence-based practices for CNNP management. Data confidentiality is maintained throughout, ensuring participant privacy during statistical analysis. TRIAL REGISTRATION: Effects of adding photobiomodulation to a specific therapeutic exercise program for the treatment of individuals with chronic nonspecific neck pain, registration number: NCT05400473, on 2022-05-27.

BACKGROUND: To date, there are no studies in the literature that define the internal structure of the Tampa Scale for Kinesiophobia (TSK) in patients with chronic neck pain based on factorial analysis. As such, we aimed to verify and identify the best structure of the Brazilian version of the TSK in patients with chronic neck pain. METHODS: We included Brazilian participants aged ≥18 years, both sexes, with self-reported neck pain for more than 3 months and pain intensity ≥3 on the Numerical Pain Rating Scale (NPRS). Dimensionality and number of TSK items were assessed using confirmatory factor analysis (CFA). We tested the following internal structures: structure 1 (1 domain and 17 items), structure 2 (1 domain and 11 items), structure 3 (2 domains and 11 items), and structure 4 (2 domains and 9 items). We used the Pain-Related Catastrophizing Thoughts Scale (PCTS) and the NPRS for construct validity. In addition, we assessed test-retest reliability for the seven-day interval using intraclass correlation coefficient (ICC2,1), Cronbach's alpha to assess internal consistency, and ceiling and floor effects. RESULTS: The study sample included of 335 patients. Most were women (77.6%), young adults (~ 34 years), single (48.4%), with complete primary education (57.3%), physically inactive (66.6%), with a mean pain duration of 46 months and a mean pain intensity of ~ 5 points on the NPRS. Redundancy was found in the following items: item 1 with item 2 (modification indices = 21.419) and item 13 with item 15 (modification indices = 13.641). Subsequently, based on these paired analyses, the items with the lowest factor loadings (items 2 and 15) were excluded. As such, TSK structure 4 was composed of two domains ("somatic focus" and "activity avoidance") and 9 items, which showed adequate fit indices and lower AIC and SABIC values. We observed significant values (p < 0.05) with a correlation magnitude greater than 0.142 to 0.657 between the two domains of the TSK-neck and the other instruments (PCTS and NPRS). We found excellent reliability (ICC2,1 ≥ 0.96) and adequate internal consistency (Cronbach's alpha ≥0.98) of the TSK-neck. Finally, ceiling and floor effects were not observed. CONCLUSION: The TSK-neck structure with two domains (somatic focus and activity avoidance) and nine items is the most appropriate for patients with chronic neck pain.

BACKGROUND: Neck pain is the fourth worldwide leading cause of disability and represents 22% of musculoskeletal disorders. Conservative intervention has been strongly recommended to treat chronic neck pain and Telerehabilitation is the alternative for the treatment of musculoskeletal conditions. There is a lack of high-quality research on the effects of telerehabilitation in patients with neck pain and functional disability. Therefore, this study aims to evaluate the effect of a telerehabilitation exercise program versus a digital booklet only with self-care information in individuals with non-specific chronic neck pain. METHODS: This is a prospectively registered, assessor-blinded, two-arm randomized controlled trial comparing a telerehabilitation exercise program versus a digital booklet with self-care information. Seventy patients will be recruited with non-specific chronic neck pain. Follow-ups will be conducted post-treatment, 6 weeks, and 3 months after randomization. The primary outcome will be disability at post-treatment (6 weeks) measured using neck pain disability. Secondary outcomes will be pain intensity levels, global perceived effect, self-efficacy, quality of life, kinesiophobia, and adherence to treatment. In our hypothesis, patients allocated to the intervention group experience outcomes that are similar to those of those assigned to the self-care digital booklet. Our hypothesis can then be approved or disapproved based on the results of the study. DISCUSSION: This randomized clinical trial will provide reliable information on the use of telerehabilitation to treat patients with chronic non-specific neck pain. TRIAL REGISTRATION: The study was prospectively registered at the Brazilian Registry of Clinical Trials (number: RBR-10h7khvk). Registered on 16 September 2022.

BACKGROUND: Text neck is regarded as a global epidemic. Yet, there is a lack of consensus concerning the definitions of text neck which challenges researchers and clinicians alike. PURPOSE: To investigate how text neck is defined in peer-reviewed articles. METHODS: We conducted a scoping review to identify all articles using the terms "text neck" or "tech neck." Embase, Medline, CINAHL, PubMed and Web of Science were searched from inception to 30 April 2022. We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMAScR) guidelines. No limitation was applied for language or study design. Data extraction included study characteristics and the primary outcome relating to text neck definitions. RESULTS: Forty-one articles were included. Text neck definitions varied across studies. The most frequent components of definitions were grouped into five basis for definition: Posture (n = 38; 92.7%), with qualifying adjectives meaning incorrect posture (n = 23; 56.1%) and posture without a qualifying adjective (n = 15; 36.6%); Overuse (n = 26; 63.4%); Mechanical stress or tensions (n = 17; 41.4%); Musculoskeletal symptoms (n = 15; 36.6%) and; Tissue damage (n = 7; 17.1%). CONCLUSION: This study showed that posture is the defining characteristic of text neck in the academic literature. For research purposes, it seems that text neck is a habit of texting on the smartphone in a flexed neck position. Since there is no scientific evidence linking text neck with neck pain regardless of the definition used, adjectives like inappropriate or incorrect should be avoided when intended to qualify posture.

BACKGROUND: Although patients with migraine show cervical muscle impairments previous studies investigating motor performance have not characterized the sample of patients with migraine according to the presence/absence of neck pain complaints. OBJECTIVE: To verify if there are differences in the clinical and muscular performance of the superficial neck flexors and extensors during Craniocervical Flexion Test in women with migraine, considering the presence or absence of concomitant symptoms of neck pain. METHODS: The cranio-cervical flexion test performance was assessed by its clinical stage test and by the surface electromyographic activity of the sternocleidomastoid, anterior scalene muscles upper trapezius and splenius capitis. It was assessed in 25 women with migraine without neck pain, 25 women with migraine and neck pain, 25 women with chronic neck pain and 25 pain-free control women. RESULTS: Poorer performance of the cervical muscles was found during the execution of the cranio-cervical flexion test, in addition to higher muscle activity, especially in the sternocleidomastoid, splenius capitis, and upper trapezius muscles in the neck pain, migraine without neck pain, and migraine with neck pain groups in comparison with the results obtained for healthy women in the control group. No difference was observed between the groups of women experiencing pain. Analysis of the extensor/flexor muscle electromyographic ratio showed that there was no difference between the groups. CONCLUSION: Poor cervical muscle performance was observed in both women with chronic nonspecific neck pain and women with migraine regardless of the presence of neck pain.

OBJECTIVE: The purpose of this study was to evaluate the intra-rater between-days reliability of the joint position sense error (JPSE) test in asymptomatic men and women, as well as in women with neck pain. METHODS: Fourteen asymptomatic men and 27 women (14 asymptomatic and 13 with neck pain) participated. The JPSE test was performed during right and left cervical rotation (10 trials for each side) in 2 sessions, with at least 7 days between them. The head repositioning error during the JPSE test (in degrees) was measured and used to calculate the intra-rater between-days reliability of the test, evaluated through the intraclass correlation coefficient and Bland-Altman analyses. Independent t tests were calculated to compare the head repositioning errors of asymptomatic women and men. The minimal detectable change was also calculated. RESULTS: The neck pain group showed higher intraclass correlation coefficient values (0.866 and 0.773, good reliability) compared to the asymptomatic men (0.478 and 0.403, poor reliability) and to the asymptomatic women (-0.161 and 0.504, poor and moderate reliability, respectively) for both right and left cervical rotation, respectively. Considering Bland-Altman analyses, the neck pain group showed better agreement between the measurements for right cervical rotation than the asymptomatic groups. CONCLUSION: The results indicate that the methodology used to perform the JPSE test in this study may be a reliable way to assess the proprioception of women with neck pain in clinical settings.

BACKGROUND: Nonspecific neck pain is a multifactorial and very common condition in adult individuals, traditional acupuncture (TA) and laser acupuncture (LA) may be treatment options for certain individuals in such a condition. However, no reports were found in the literature comparing the effectiveness of TA and LA in cases of chronic nonspecific neck pain. Therefore, the aim of the present study is to investigate the effectiveness of TA and LA therapies in individuals with chronic nonspecific neck pain, noting which one is more efficient for this condition. The result of this research will have direct implications for pain management and, consequently, may benefit individuals suffering from nonspecific chronic neck pain. METHODS/DESIGN: This will be a controlled and randomized clinical trial. Eighty-four individuals will be recruited and distributed equally and randomly into 3 groups: TA (which will receive the acupuncture treatment with needles), LA (which will receive the laser acupuncture treatment), and Sham (who will receive the placebo intervention). The acupuncture points (Tianzhu, Fengchi, Jianjing, and Jianzhongshu) will be stimulated bilaterally. The primary outcome will be pain intensity, determined using the Numerical Rating Scale. The secondary outcomes will be pressure pain threshold, temporal summation of pain, conditioned pain modulation, use of analgesic medicines after treatment, and the global perceived effect scale. The assessments will be performed immediately before and after the treatment, which will be a single session, at the follow-up and 1 month after the end of the treatments; evaluation will be made of the pain intensity and the global perceived effect. Statistical analysis of the data obtained will consider a significance level of p < 0.05. DISCUSSION: This study will provide evidence concerning the effects of LA treatment, in comparison with TA and sham intervention, leading to benefits for individuals suffering from chronic nonspecific neck pain.

OBJECTIVE: To translate, cross-culturally adapt and assess measurement properties of the translated version of the Northwick Park Neck Pain Questionnaire into Brazilian Portuguese. DESIGN: Cross-sectional study. SETTINGS: University healthcare facility and online. PARTICIPANTS: People with chronic neck pain (n = 178). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants answered the translated version of Northwick Park Neck Pain Questionnaire, the Neck Disability Index, the Numerical Rating Scale for pain, the Tampa Scale for Kinesiophobia and the Pain Catastrophizing Scale. Seven to ten days after that, a subset of 84 participants answered the Northwick Park Neck Pain Questionnaire again. The structural (exploratory and confirmatory factor analyses) and construct validities, internal consistency, reliability and concordance were assessed. Level of significance was set at 5%. RESULTS: Participants' (35.6 ± 13.5 years old) with symptoms duration of 54.4 ± 60.4 months scored 25.5 ± 14.0 on the Brazilian Northwick Park Neck Pain Questionnaire and 11.9 ± 5.8 on the Neck Disability Index. The structural analysis showed that the short version of the Northwick Park Neck Pain Questionnaire has an adequate structure to measure disability due to neck pain. Correlations with other questionnaires were between 0.268 and 0.678, Cronbach's alfa was 0.76, intraclass correlation coefficient was 0.96, standard error of measurement was 2.74 and minimal detectable change was 7.60. CONCLUSION: The short version of the Northwick Park Neck Pain Questionnaire is valid and reliable to be used in patients with chronic neck pain, as it presented adequate measurement properties of structural and construct validity, reliability and concordance.

OBJECTIVE: To evaluate the measurement properties of the Brazilian version of the Copenhagen Neck Functional Disability Scale (CNFDS) in patients with chronic neck pain. METHODS: One hundred and five patients were included in the study. The structural validity of the CNFDS was assessed by exploratory and confirmatory factor analysis with the following fit indices: chi-square divided by degrees of freedom (chi-square/df), root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker-Lewis index (TLI). To test the construct validity, the CNFDS score was correlated with the Numerical Pain Rating Scale, the Tampa Scale of Kinesiophobia, the Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index (NDI). A subsample of 43 patients filled the CNFDS at two different times, and test-retest reliability was measured using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC). The internal consistency of the CNFDS was analyzed by Cronbach's alpha. RESULTS: CNFDS presented a unidimensional structure, with goodness of fit indices: chi-square/df = 1.37, CFI = 0.94, TLI = 0.93, RMSEA = 0.059. The CNFDS showed satisfactory results of reliability (ICC = 0.93) and internal consistency (Cronbach's alpha = 0.84). The SEM was 1.72 and the MDC was 4.76. The CNFDS showed a high correlation with the NDI (rho = 0.718) and a low correlation with the other instruments. There were no floor and ceiling effects. CONCLUSION: The Brazilian version of the CNFDS with a one-dimensional structure and 15 items has adequate measurement properties.

OBJECTIVES: To assess test-retest reliability, internal consistency, construct validity, and the presence of ceiling and floor effects in the Brazilian version of the Short-Form Neck Disability Index (SF-NDI) in patients with chronic neck pain. METHODS: One hundred and fifty-six patients answered the Numerical Pain Rating Scale (NPRS), Short-Form Neck Disability Index (SF-NDI), Tampa Scale of Kinesiophobia (TKS), Pain Catastrophizing Scale (PCS), and the 36-Item Short-Form Health Survey questionnaire (SF-36). Another sample (n = 51) filled the SF-NDI at two different times, and test-retest reliability was measured using the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable change (MDC). The internal consistency of the SF-NDI was analyzed by Cronbach's alpha. To determine construct validity, Spearman's correlation coefficient was used to determine the magnitude of the correlation between the score of the SF-NDI and other measurement instruments: NPRS, TKS, PCS, SF-36, and original NDI. RESULTS: SF-NDI presented substantial reliability (ICC = 0.844) and adequate internal consistency (Cronbach's alpha = 0.778). We observed significant values and with a correlation magnitude greater than 0.80 for the SF-NDI with the original NDI, between 0.30 and 0.50 for the correlations with TKS, and the functional capacity and pain domains of the SF-36, and less than 0.30 with the other study instruments. No participant reached the maximum score. Ceiling and floor effects were not observed. CONCLUSIONS: SF-NDI with 5 items has adequate measurement properties in Brazilian chronic neck pain patients.

BACKGROUND: This study analyzed neck pain estimates in Brazil and its states between 2000 and 2019, in view of the country's lacking epidemiological data. METHODS: An analysis was performed of the GBD 2019 estimates by location, sex, and age, per 100,000 population, with uncertainty intervals (95% UI). Brazilian estimates were compared to global, Mexican, English, and American rates. RESULTS: Global, Brazilian, and Mexican prevalence numbers were statistically homogeneous and stable in the period. Throughout the period analyzed in the study, Brazilian neck pain prevalence (2241.9; 95%UI 1770.5-2870.6) did not show statistical differences when compared to global (2696.5; 95%UI 2177.0-3375.2) or Mexican (1595.9; 95%UI 1258.9-2058.8) estimates. Estimates observed in the USA (5123.29; 95%UI 4268.35-6170.35) and England (4612.5; 95%UI 3668.8-5830.3) were significantly higher. In 2019, when compared to the USA and England, age-standardized prevalences were lower globally, in Brazil, and in Mexico. Prevalences in Brazilian states were similar, being that Roraima (1915.9; 95%UI 1506.5-2443.1) and the Federal District (1932.05; 95%UI 1515.1-2462.7) presented the lowest and highest values respectively. The exception was the state of São Paulo (3326.5; 95%UI 2609.6-4275.5). There was no statistical difference by sex, but the prevalence tended to increase with aging. In 2019, the Brazilian prevalence was 2478.6 (95% UI 1791.0-3503.8), 5017.2 (95%UI 3257.26-7483.8), and 4293.4 (95% UI 2898,8-6343.9), for those aged 15 to 49, 50 to 69, and 70+ years. There was no statistical difference among the YLDs in all locations and times. CONCLUSIONS: Brazil is going through a fast-paced process of populational aging; a higher prevalence of neck pain in middle-aged individuals and the elderly highlights the need for lifelong prevention initiatives. The higher rates observed among higher-income populations and the homogeneity of the Brazilian estimates suggest a lack of robust epidemiological data in lower-income countries.

OBJECTIVE: The aim of this study was to evaluate the intra- and inter-rater reliability of pressure pain threshold measurement on myofascial trigger points in the trapezius muscle in women with chronic neck pain. METHODS: This reliability study involved 30 volunteers with neck pain for more than 90 days. The assessment procedures were performed by blinded researchers. Two examiners, who were previously trained in the use of algometry, independently performed two assessments of the pressure pain threshold at two time intervals, one week apart. RESULTS: The study sample consisted of 30 young adult women. Excellent intra- and inter-rater reliability were found for the pressure pain threshold on myofascial trigger points, with intraclass correlation coefficient values ranging between 0.752 and 0.874, standard error of measurement ranging between 0.18 and 0.22 kg/cm2, and minimum detectable change ranging between 0.45 and 0.62 kg/cm2. CONCLUSION: The present study showed that the assessment of pressure pain threshold through algometry presents satisfactory intraclass correlation coefficient values, considering different time and examiners, contributing to the spread of the use of this tool as a quantitative method of pain evaluation in myofascial trigger points.

OBJECTIVE: To investigate the structural validity of the Brazilian version of the Neck Bournemouth Questionnaire in patients with chronic neck pain. DESIGN: Cross-sectional study. SETTING: Community participants collected via online platform. SUBJECTS: Participants with neck pain (minimal pain intensity of 3 points at rest on 11-point Numerical Rating Scale), both genders and aged ⩾18 years old. MAIN MEASURE: The Numerical Rating Scale, Neck Disability Index, Pain-Related Catastrophizing Thoughts Scale, Tampa Scale of Kinesiophobia and the Neck Bournemouth Questionnaire were completed. Exploratory and confirmatory factor analyses were used to identify dimensionality and to compare different structures of the Neck Bournemouth Questionnaire. RESULTS: We included 103 participants. The sample consisted mostly of adults (mean age = 33.64 years, standard deviation = 10.48 years), females (n = 82, 79.6%), lean, single and with higher education. The exploratory factor analysis with implementation of the parallel analysis identified the one-dimensional structure of the Neck Bournemouth Questionnaire, with a Kaiser-Meyer-Olkin value of 0.80 and Bartlett's test significant (P < 0.05). We observed that all structures tested in this study presented a high amount of residues in confirmatory factor analysis, which were identified by the value of root mean square error of approximation > 0.08 and chi-square/degree of freedom > 3.00. CONCLUSION: The internal structure of the Brazilian version of the Neck Bournemouth Questionnaire is not clear and well-defined. It was not possible to identify the construct measured by the instrument in individuals with chronic neck pain.

OBJECTIVES: To evaluate the discriminative validity and provide a clinical cut-off of the craniocervical flexion test (CCFT) in migraineurs stratified by the report of neck pain, headache-related disability and neck disability. METHODS: Fifty women without headache and 102 women with migraine were recruited by convenience from a local tertiary care setting. Migraine diagnosis followed the International Classification of Headache Disorders. All volunteers underwent the CCFT. Patients with migraine answered the Migraine Disability Assessment (MIDAS) and Neck Disability Index (NDI) questionnaires. Discriminative validity was verified by group comparison, and the clinical cut-off was obtained and classified according to the diagnostic accuracy of the CCFT. RESULTS: The CCFT presented discriminative validity for comparing control (median = 28, IQR = 6) with migraine (median = 26, IQR = 4, P = .01) and migraine with neck pain (median = 26, IQR = 4, P = .01), but not among the migraine subtypes with disability by migraine or neck pain-related disability on the MIDAS and NDI. The diagnostic accuracies were classified between poor and not discriminating with the area under the receiver operating characteristic curve ranging from 57% to 69% and non-acceptable values of sensitivity, specificity and positive and negative likelihood ratios. CONCLUSION: The CCFT can discriminate asymptomatic controls from migraine patients with and without neck pain. However, it cannot discriminate patients with migraine according to their pain-related disability. Also, the CCFT does not offer an optimal cut-off value in migraine patients adequate to clinical practice.

Introduction: osteopathy addresses the patient globally and applies manual treatment techniques. A retrospective evaluation was carried out on 447 patients to know the results of the treatment of lumbar and cervical pain. Material and methods: 447 patients with a diagnosis of low back pain and cervical pain (77.4% female) were included in this study. The patients already had undergone conventional treatments without having achieved satisfactory results. The patients were evaluated with the numerical value of pain scale (VNS), and Oswestry scores (ODI) and the index of disability of the cervical region (NDI). The 4 intervening osteopaths are certified professionals in this discipline. Results: 42.8% of the patients were referred by the Traumatology Service and 41.3% by the Family Medicine Service. 34.2% had a diagnosis of lumbar pain and 20.8% were diagnosed with neck pain. Statistically significant differences were found between the first and last sessions in both the pain assessment and the scores used. Discussion: in patients with low back pain and neck pain who had not obtained satisfactory results with previous conventional treatments, osteopathic treatment resulted in significant improvements in all the parameters evaluated.

BACKGROUND: Pressure pain threshold (PPT) is decreased in several musculoskeletal disorders, giving indirect evidence regarding pain status. Despite the fact that PPT has been already proven to be reliable in patients with acute conditions, there is great variability of methods and results observed within studies, and only a few evidences confirming its reliability in chronic conditions. OBJECTIVE: The objective of this study was to determine the test-retest reliability of PPT in the neck and low back regions to discriminate individuals with neck or low back pain from healthy individuals. Additionally, one secondary aim was to establish the minimum detectable change (MDC) and the standard error of measurement for future clinical studies and interventions. METHODS: In this reliability study, 74 individuals (15 individuals from the neck pain and 17 from the neck control group; 21 individuals from the low back pain and 21 from the low back control group). PPT was measured in the neck region (suboccipital, trapezius and supraspinal muscles) and in the lower back region (paraspinal muscles in the levels of L1, L3 and L5). Intrarater reliability was assessed using intraclass correlation coeficient and Bland-Altman. RESULTS: Excellent intra-rater reliability was observed for both (ICC of 0.874 for the neck pain versus ICC of 0.895 in neck control group; ICC of 0.932 for the low back pain group versus ICC of 0.839 for the control group). A small bias was observed for all groups (-0.08 for the neck pain group versus 0.10 in the control group; and 0.32 in low back pain group versus 0.44 in the control group). Minimum detectable change of 0.63 kgf of neck pain and 1.21 kgf of low back pain was calculated. It was found difference in PPT between pain and control groups (p< 0.05). CONCLUSION: It may be suggested that the protocol with PPT is reliable and able to discriminate individuals with and without neck and low back pain with a minor measurement error. Therefore, this method may be used to detect possible progress after interventions in patients with neck or low back pain.

STUDY DESIGN: Observational cross-sectional study. OBJECTIVE: The aim of this study was to investigate the association between text neck and neck pain (NP) in adults. SUMMARY OF BACKGROUND DATA: It has been hypothesized that the inappropriate neck posture adopted when texting and reading on a smartphone, called text neck, is related to the increased prevalence of NP. METHODS: The sample was composed of 582 volunteers aged between 18 and 65 years. Sociodemographics, anthropometrics, lifestyle, psychosocial, NP, and smartphone use-related questions were assessed by a self-reported questionnaire. Text neck was assessed by measuring the cervical flexion angle of the participants standing and sitting while typing a text on their smartphones, using the Cervical Range of Motion (CROM) device. RESULTS: Multiple logistic regression analysis and linear regression analysis showed the cervical flexion angle of the standing participant using a smartphone did not associate with the prevalence of NP (odds ratio [OR]â=â1.00; 95% confidence interval [CI]: 0.98-1.02; Pâ=â0.66), NP frequency (ORâ=â1.01; 95% CI: 1.00-1.03; Pâ=â0.056), or maximum NP intensity (beta coefficientâ=â-5.195 × 10-5; 95% CI: -0.02 to 0.02; Pâ=â0.99). Also, the cervical flexion angle of the sitting participant using the smartphone did not associate with NP (ORâ=â0.99; 95% CI: 0.98-1.01; Pâ=â0.93), NP frequency (ORâ=â1.01; 95% CI: 0.99-1.02; Pâ=â0.13), or maximum NP intensity (beta coefficientâ=â0.002; 95% CI: -0.002 to 0.02; Pâ=â0.71). CONCLUSION: Text neck was not associated with prevalence of NP, NP frequency, or maximum NP intensity in adults.Level of Evidence: 4.

STUDY DESIGN: Cross-sectional study. OBJECTIVE: The aim of this study was to assess the structural validity of the Brazilian version of the Neck Disability Index (NDI) in patients with chronic neck pain. SUMMARY OF BACKGROUND DATA: NDI is widely used in clinical and scientific contexts, although its structure has not been evaluated in the Brazilian version. METHODS: Native Brazilian Portuguese speakers, aged ≥18 years, with neck pain complaint of at least 3 months, and minimal pain rating of 3 points at rest or during neck movements were included. Exploratory factorial analysis (EFA) and confirmatory factorial analysis (CFA) were used. In EFA, the adequacy of the model was assessed using Bartlett test of sphericity and Kaiser-Meyer-Olkin test. In CFA, the goodness-of-fit was assessed by the indices: root mean square error of approximation with 90% of confidence interval, comparative fit index, Tucker-Lewis Index, standardized root mean square residual, and χ2/degree of freedom. Akaike information criterion (AIC) and Bayesian information criterion (BIC) were considered to compare the models. RESULTS: Two hundred fifty-four participants with chronic neck pain were included. The NDI model with one domain and five items presented the most adequate goodness-of-fit indexes and the lowest values of AIC and BIC, when compared with models with one domain and 10, eight, or seven items, and with the model with two domains and 10 items. CONCLUSION: In the Brazilian context, the NDI version with one domain and five items (personal care, concentration, work, driving, and recreation) presents the best structure according to the factorial analysis.Level of Evidence: 5.

Neck pain is a common condition with a high prevalence worldwide. Neck pain is associated with significant levels of disability and is widely considered an important public health problem. Neck pain is defined as pain perceived between the superior nuchal line and the spinous process of the first thoracic vertebra. In some types of neck conditions, the pain can be referred to the head, trunk and upper limbs. This article aims to provide an overview of the available evidence on prevalence, costs, diagnosis, prognosis, risk factors, prevention and management of patients with neck pain.
