More neck pain, less spinal mobility, altered sitting posture: Sagittal spinal alignment and mobility in women with chronic neck pain

BackgroundIncreasing evidence suggests that people with chronic neck pain (CNP) may display altered biomechanics beyond the cervical spine. However, whether spinal alignment and mobility are associated with neck pain is not clarified. ObjectivesTo investigate whether there is a significant association between neck pain intensity and sagittal spinal alignment and mobility in people with CNP, and to examine whether sagittal spinal alignment and mobility differ according to pain intensity. DesignA cross-sectional study. MethodForty-four women with CNP were included. The neck pain intensity at rest and during neck movements was assessed with the visual analogue scale (VAS). A skin-surface measurement device was used to assess sagittal alignment and mobility while sitting and standing. Linear regression analysis was used to assess associations. Participants were divided into two groups according to the pain intensity as group with mild pain (VAS≤4.4 cm) and group with moderate to severe pain (VAS>4.4 cm) and compared using the analysis of covariance. ResultsGreater resting pain was associated with a more forward trunk during sitting (Beta = 0.433, p < 0.05). Greater pain during neck movements was associated with increased lumbar lordosis during sitting (Beta = −0.376, p < 0.05). Classified by pain intensity at rest, trunk mobility while sitting was lower and forward trunk inclination and sacral kyphosis while sitting were higher in those with moderate/severe pain (η2p = 0.093–0.119, p < 0.05). By pain intensity during neck movements, women with moderate/severe pain exhibited lower sacral mobility while sitting (η2p = 0.129, p < 0.05). ConclusionsAddressing the entire spine in the assessment and management of CNP may help reduce pain.

Efficacy of craniosacral therapy in cervicogenic headache: a literature review

BackgroundNeck discomfort is a frequent problem that can impair quality of life and make it difficult to perform daily tasks. Pain from neck strain is not limited to the cervical spine; it can also radiate into the skull and result in a headache of cervical origin, known as cervicogenic headache. Craniosacral can cure a wide array of musculoskeletal and neurological conditions, including headaches, but there is little evidence in the literature of its efficacy, particularly regarding cervicogenic headaches.ObjectiveTo determine the effectiveness of craniosacral therapy (CST) for cervicogenic headache and improve our understanding of cervicogenic headache.MethodsA review of the literature was performed using the following electronic search bases: PubMed, Google Scholar, Scopus and The Cochrane library. To perform the search, these MeSH terms were used: “Cervicogenic headache” AND “Neck pain” AND “Craniosacral therapy” AND ‘Headache’ between the date 2020 to 2022.ResultsEleven articles were included in the literature review. Overall, the results of published articles indicate 97.5–100% of the patients thought the treatment program was satisfactory. No adverse effects were reported. It has been demonstrated that CST is particularly safe and effective in lowering the intensity of neck pain. It may also enhance the quality of life and functional impairment for up to three months following the intervention. In addition to the conventional medical therapy, CST may be a beneficial therapeutic option for persistent and recurrent neck discomfort.ConclusionThis review shows that CST is very effective for the treatment of cervicogenic headaches. CST evaluation is feasible in randomized controlled trials and may offer insightful results to enhance therapeutic decision-making.

Comparison of trunk muscle endurance between women with and without chronic neck pain

PurposeTo compare trunk flexor, extensor, and lateral flexor muscle endurance between women with moderate to severe disability due to chronic neck pain (CNP) and asymptomatic women. DesignObservational case-control study. MethodsThirty women with CNP and Neck Disability Index scores ranging from 30% to 70% and 28 asymptomatic women were included. The visual analog scale was used to assess neck pain intensity at rest and during activity. To assess trunk muscles endurance, trunk flexor endurance test, Sorensen test, and side bridge endurance test were performed. ResultsAnalysis of covariance indicated that neck pain group had lower body mass index-adjusted endurance times of trunk flexor, extensor, and lateral flexor muscles with large effect sizes (p < .001, η2 = 0.378-0.696). Trunk flexor endurance time showed a moderately negative correlation with neck pain intensity at rest and a weakly negative correlation with neck disability score (r = –460 and –365, p < .05). ConclusionsWomen with moderate to severe disability due to CNP exhibited decreased trunk muscle endurance, which may be a predisposing factor for low back pain. Also, trunk flexor endurance was related to neck pain complaints. A holistic approach, addressing the entire spine rather than focusing solely on the cervical region, might be useful for managing CNP. Clinical ImplicationsThe findings of reduced endurance in trunk muscles should be considered when incorporating interventions in the management of CNP to effectively address pain and disability.

Effect of thoracic manipulation on neck pain in the mobility group: A randomized controlled trial.

Thoracic spine manipulation (TSM) increases the thoracic spine's range of motion (ROM), effectively reducing pain intensity and disability in patients with mechanical neck pain. We aimed to determine the effect of TSM on neck pain intensity and functional impairment in patients classified under the "mobility" category in Childs' classification. In this randomized controlled trial, patients with mechanical neck pain who met the inclusion criteria were randomly assigned to either the TSM (n = 21) or sham manipulation (n = 20) group. The primary outcomes were pain during neck rotation and subjective improvement assessed using the Numerical Pain Rating Scale (NPRS) and Global Rating of Change (GROC), respectively. The secondary outcomes were NPRS at rest, disability (assessed using the Neck Disability Index [NDI]), and ROM of the cervical and thoracic spine rotation. Outcome measurements were performed at baseline, immediately after treatment, 1 week after treatment, and at the 4-week follow-up. Linear mixed models were used to analyze the NPRS, NDI, and ROM. The GROC was analyzed using a chi-square test for the percentage recording ≥+4; the means of each group were compared using an unpaired t-test. The NPRS with neck rotation, neck and thoracic ROM, and NDI showed significant interactions between the groups. The NPRS with neck rotation was significantly lower in the TSM group than in the sham group at all time points after the treatment (p < 0.001). There was no difference between the groups in the proportion showing moderate (≥+4) improvement according to the GROC; however, there was a significant difference in the mean values (p = 0.013). Incorporating TSM into treatment protocols may improve clinical outcomes in patients with neck pain, potentially leading to better pain management and functional recovery. Therefore, physiotherapists should consider TSM as a viable and effective intervention to improve patient outcomes in neck pain rehabilitation.

Spinal stabilization exercises for transversus abdominis and lumbar multifidus thickness via telerehabilitation and face-to-face approaches in patients with nonspecific chronic neck pain: a randomized controlled trial.

Strengthening the muscles of the lumbar region in individuals with neck pain may be protective against future back problems. In addition, telerehabilitation applications, which gained momentum in the literature and clinical practice during the COVID-19 pandemic, are among the applications preferred by patients thanks to their various advantages. This study aimed to compare the effects of telerehabilitation and spinal stabilization exercises applied with face-to-face approaches on the thickness of the transversus abdominis (M.TrA) and lumbar multifidus (M.LM) muscles in patients with nonspecific neck pain. The primary outcomes were the thickness of the M.TrA and M.LM. Neck pain intensity and neck disability were secondary outcomes. Muscle thickness was evaluated with an ultrasound device, neck pain intensity was assessed with a visual analog scale, and disability was assessed with the Neck Disability Index. Patients were randomly assigned to the telerehabilitation group (TRG) (n = 13) or the control group (CG) (n = 13). While the TRG did the exercises with live videos and video recordings, the CG did exercises face-to-face in the clinic. Both groups performed the same exercises for 45 minutes per session 3 days a week for 8 weeks. At the end of the treatment, the thicknesses of the M.TrA and M.LM were increased and neck pain intensity and neck disability were decreased in both groups (p < 0.05). The groups were similar in terms of these variables (p > 0.05). Telerehabilitation and face-to-face spinal stabilization exercises are both beneficial for spinal muscle architecture and clinical variables as a preventive measure against future lower back problems in individuals with neck pain.

Cervical orthosis does not improve postoperative pain following posterior cervical fusion: a randomized controlled trial.

To determine whether postoperative neck pain in the first 4 weeks following multi-level posterior cervical fusion (PCF) with orthosis is equivalent to multi-level PCF without orthosis. Patients were randomly assigned in a 1:1 ratio to postoperative orthosis (CO) for 6 weeks or no orthosis (NO). Randomization was stratified by indication (traumatic vs. degenerative), and preoperative opioid use. A model of longitudinal regression for repeated measures was used. The two-sided 95% confidence interval (CI) was used to test equivalence. If the CI lay between the pre-determined margin of equivalence (-2.0 to + 2.0 pain score) the two groups were considered equivalent. A multiple imputation procedure was used to replace missing data. Thirty-one patients were enrolled in each group. At baseline, the CO group had more neck pain (5.3 vs. 3.2, p = 0.013). The Four week post-operative neck pain intensity score was 4.6 ± 0.3 for the CO group vs. 4.9 ± 0.3 for the NO group. The 95% confidence interval (-1.2 to 0.6) was within the pre-determined equivalence margin. Neck Disability Index, quality-of-life scores, and arm pain were similar. Eleven patients in the CO group and 12 patients in the NO group had an adverse event. The CO group had reduced range of motion at 6 weeks. Pain scores over the first 4 weeks after surgery were equivalent for patients undergoing multi-level PCF treated with or without a cervical orthosis. Our findings do not support the routine use of a postoperative cervical orthosis for postoperative pain control. Clinical Trials Registration Number NCT04308122, April 22, 2020.

Comparison of Outcomes of Physical Therapy Exercises Combined with Either a Video-Based Smartphone Application System or a Written Exercise Program Handout in 34 Patients with Non-Specific Neck Pain.

BACKGROUND An exercise program was developed using risk factors for non-specific neck pain. This study aimed to compare the effects video-based versus image- and text-based remote home training performed using this exercise program in patients with non-specific neck pain. MATERIAL AND METHODS Among the 37 patients with non-specific neck pain recruited, 34 patients who satisfied the inclusion criteria were enrolled in this study. The participants were randomized into the experimental (n=17) and control (n=17) groups. The patients in the experimental group performed exercises using a video-based application system, whereas those in the control group performed exercises using an image- and text-based printout. In-home training was implemented for 6 weeks in both groups. The neck pain intensity, disability index, active range of motion (aROM), forward head posture (FHP), and compensatory neck flexion were measured before and after the intervention. The within-group and between-group differences were analyzed at the end of the interventions. RESULTS Improvements in pain intensity, cervical ROM, disability index, FHP, and compensatory neck flexion were observed after in-home training in the experimental group (P.05). Between-group comparison revealed that the experimental group exhibited greater improvement in pain intensity, cervical ROM, and FHP than the control group (P<.05). CONCLUSIONS The findings of this study suggest that the video-based home exercise program improved pain intensity, aROM, neck disability index, FHP, and compensatory neck flexion in patients with non-specific neck pain.

Effects of Kinesio Taping on Neck Pain: A Meta-Analysis and Systematic Review of Randomized Controlled Trials.

Neck pain constitutes a prevalent and burdensome health issue, substantially impairing patients' quality of life and functional capabilities. Kinesio taping (KT), a commonly employed intervention within physical therapy, holds promise for mitigating such symptoms; however, a comprehensive evaluation of its efficacy and evidence base is lacking. Therefore, this study endeavors to systematically investigate the therapeutic effects of KT on both subjective neck pain intensity and objective measures of physical activity limitations through a rigorous meta-analytic approach. By synthesizing existing literature and scrutinizing methodological nuances, we aim to furnish healthcare practitioners with evidence-informed insights, facilitating more judicious clinical decision-making and optimizing patient outcomes. According to the PRISMA guidelines, we conducted searches on PubMed, Cochrane Library, Embase, and Web of Science for randomized controlled trials (RCTs) investigating the efficacy of KT in treating neck pain. Screening was performed based on predefined inclusion and exclusion criteria. Characteristics of the included RCTs were extracted. Trial heterogeneity was assessed using the I2 statistic. Meta-analysis was conducted using Stata 17 software. Risk of bias and methodological quality were evaluated using the Cochrane Risk of Bias 2 tool and the PEDro scale, respectively. In our analysis of 10 RCTs involving 620 patients meeting our inclusion criteria, KT demonstrated significant beneficial effects on neck pain, notably surpassing conventional treatment (weighted mean difference = -0.897, 95% CI -1.30 to -0.49, P < 0.001). Subgroup analysis further revealed that KT exhibited particularly pronounced efficacy in the treatment of nonspecific neck pain and mechanical neck pain, with a more substantial effect observed after 4 weeks of KT intervention compared to 1 week. Moreover, KT demonstrated superior efficacy in alleviating pain symptoms compared to both conventional treatment and sham interventions. KT has demonstrated efficacy in reducing neck pain and improving cervical dysfunction among patients. Prolonged KT treatment or its combination with other therapeutic modalities may potentially enhance therapeutic outcomes. PROSPERO CRD42024524685.

Effectiveness of McKenzie exercises plus stabilization exercises versus McKenzie exercises alone on disability, pain, and range of motion in patients with nonspecific chronic neck pain: A randomized clinical trial.

Chronic nonspecific neck pain is a common disorder that causes disability and reduced quality of life. Effective conservative treatment options are needed to manage this condition. This randomized trial compared the efficacy of McKenzie exercises alone versus McKenzie plus cervical and scapulothoracic stabilization training for patients with chronic nonspecific neck pain. A randomized controlled trial was conducted in an outpatient physical therapy clinic. 76 patients with chronic (> 3 months) neck pain were randomized to 6 weeks of either McKenzie exercises alone (n= 38) or McKenzie plus stabilization exercise (n= 38). The McKenzie protocol included posture correction, range of motion exercises, and lateral neck stretches. The stabilization program added targeted exercises for the neck and scapula. The combination of McKenzie plus stabilization exercises resulted in significantly greater reduction in current neck pain intensity compared to McKenzie alone at 6 weeks (mean difference: -1.2 points on 0-10 scale, 95% CI -1.8 to -0.6; p< 0.001). Neck disability improved in both groups. Cervical range of motion also improved more with the addition of stabilization, except for extension. Adding specific cervical and scapulothoracic stabilization exercises to a standard McKenzie protocol led to clinically meaningful reductions in neck pain compared to McKenzie therapy alone in patients with chronic nonspecific neck pain. This combined approach can improve outcomes.

Reliability and construct validity of the Craniocervical Flexion Test in patients with migraine

BackgroundMigraine may be accompanied by several cervical musculoskeletal dysfunctions, for example an altered performance on the Craniocervical Flexion Test (CCFT). However, CCFT measurement properties are still unclear in patients with migraine. ObjectivesTo determine intra- and inter-examiner reliability, construct validity, standard measurement error (SEM), and minimal detectable change (MDC) of the CCFT in patients with migraine. MethodsWomen diagnosed with migraine were considered eligible for this study. Participants were assessed by two examiners for the inter-examiner reliability, and with 7–10 days interval for the intra-examiner reliability. Construct validity was assessed considering headache and neck pain frequency and intensity, and self-reported questionnaires, including the Headache Impact Test – 6 items (HIT-6), the 12-item Allodynia Symptom Checklist/Brazil (ASC-12), and the Neck Disability Index (NDI). In addition, participants performed cervical endurance and maximal voluntary isometric contraction of the cervical flexors. ResultsA total of 103 women with migraine were recruited. The intra-examiner reliability was rated as good (ICC= 0.81, 95% CI: 0.73, 0.87), while the inter-examiner reliability was rated as moderate (ICC= 0.55, 95% CI: 0.40, 0.67). The intra and inter-examiner SEM were 1.31 and 1.36 mmHg respectively, and MDC were 3.63 and 3.77 mmHg. The HIT-6 and the cervical endurance flexion test were associated with the CCFT in a multiple linear regression model (p = 0.004, R = 0.35). ConclusionThe CCFT presents adequate intra- and inter-examiner reliability. Better performance on the CCFT test was associated with better HIT-6 scores and greater cervical endurance time, which was not influenced by the presence of neck pain.

Higher Neck Pain Intensity and Pain Catastrophizing Soon After A Whiplash Injury Partially Explain the Presence of Persistent Headache: A Prospective Study.

To understand whether pain-related factors soon after a whiplash injury can explain the presence of chronic headache. A prospective study with a follow-up of 6 months was performed, including 42 patients with acute whiplash-associated disorders. Neck pain intensity, the Neck Disability Index, the Tampa Scale of Kinesiophobia, the Pain Catastrophizing Scale, and the Anxiety State-Trait Scale were assessed at baseline. Differences in clinical characteristics between those with and without headache at 6 months were determined. The relative risk of presenting with headache was evaluated. A logistic regression model was performed to assess which factors at baseline could explain the presence of headache at 6 months. At 6 months, one-third of the sample presented with chronic headache. Significant differences were found for several outcome measures when people with and without headache were compared ( P <0.001). The highest relative risk of presenting with headache was found for moderate/severe levels of pain catastrophizing during the acute phase (RR=15.00, 95% CI=3.93, 57.22). The level of neck pain intensity and pain catastrophizing at baseline partially explained the presence of headache at 6 months ( R2 =0.627). The risk of presenting with persistent headache attributed to a whiplash injury is increased when people present with higher neck pain intensity and pain catastrophizing soon after a whiplash injury. Evaluating neck pain intensity and pain catastrophizing at baseline may assist in identifying those more likely to develop chronic headache, potentially providing an opportunity for early targeted interventions.

Neck Pain among Dental Practitioners

Dentistry is a demanding profession regarding concentration and precision. Performance of dental treatment results in a very inflexible work posture and under stressful body position for prolonged period, bad pattern and faulty neck posture disturbs the normal spine curve of neck leading to muscular imbalance and consequently lead to neck pain and disability. The aim of the study is to measure the prevalence of neck pain among the Dental surgeons in Dhaka city of Bangladesh. This is a cross-sectional survey type study. Dentists who reported neck pain last for 12 months were selected as a study population. After screening Neck pain intensity was measured by using 101 NPRS. Then the dentists were given NPAD questionnaire to measure disability level due to neck pain. About 36.60% dental surgeons had neck pain whereas 63.40% did not have. Among 71 dental surgeons 55.20% had moderate neck pain according to neck pain and disability scale (NPAD scale) followed by 23.90% had mild pain and 20.90% had severe pain respectively. Statistically no significant association was found between neck pain and age group. Statistically significant association was found between neck pain and duration of job of the respondents. Moreover, study found that negative correlation between age of the dental surgeons and pain score and it was not statistically significant. It is concluded from the study that prevalence of neck pain among dental surgeons working in Dhaka city is still high i.e. one in every three dental surgeons suffered from neck pain. Preventive musculoskeletal awareness campaign and posture training can be conducted among dental surgeons.

Correlations of The Central Sensitization Inventory, conditioned pain modulation, cognitions and psychological factors in individuals with chronic neck pain: A cross-sectional study.

Chronic neck pain (CNP) is a global public health problem, with high prevalence and absenteeism rates. Central sensitization (CS) as a basis for chronic pain may play an essential role in its development and progression. It is often comorbid with low conditioned pain modulation (CPM) effects, cognitions, and psychological problems. The purposes of this study were to (1) explore the relationship between pain-related cognitions and psychological factors, CPM effects, and the central sensitization inventory (CSI) scores; and (2) determine whether cognitions and psychological factors can predict CSI scores and CPM effects in individuals with CNP. Fifty-four individuals with CNP were recruited for this cross-sectional study. The following outcome measures were evaluated: The CSI (screening tool) was compared with the cold pressor test (CPT), which was the psychophysical test used to assess the CPM; neck pain intensity using the visual analogue scale (VAS), as well as pain-related cognitions (including kinesiophobia and pain catastrophization) and psychological states (including anxiety and depression) using self-report questionnaires. CSI score was not associated with the CPM effect (r = 0.257, p > 0.05), and no cognitions or psychological factors were associated with CPM (p > 0.05), but CSI score was moderately positively correlated with kinesiophobia (r = 0.554, p < 0.01), lowly positively correlated with pain catastrophization (r = 0.332, p = 0.017) and anxiety (r = 0.492, p < 0.01), but not depression (r = 0.207, p = 0.132). Multiple linear regression analysis showed that kinesiophobia (B = 1.308, p < 0.01) and anxiety (B = 1.806, p = 0.02) were significant positive predictors of CSI score. The findings confirm some of our hypotheses. Accordingly, the findings inferred that the CSI does not seem to respond to CPM effect in patients with CNP effectively. In addition, CSI score was associated with cognitions and psychological factors, of which kinesiophobia and anxiety were effective predictors. In clinical practice, pain-related cognitions and psychological factors should be fully considered to manage neck pain efficiently.

The Relationship between Heart Rate Variability, Pain Intensity, Pain Catastrophizing, Disability, Quality of Life and Range of Cervical Motion in Patients with Chronic Non-Specific Neck Pain: A Cross-Sectional Study.

The purpose of the present cross-sectional study was to examine the relationship between heart rate variability (HRV) and the range of cervical motion, disability, pain intensity, pain catastrophizing, and quality of life in patients with chronic, non-specific neck pain. Thirty-five patients, aged 20-48 years, with chronic non-specific neck pain, completed validated questionnaires regarding neck pain intensity, pain-associated disability, catastrophic thoughts, and quality of life. The range of cervical motion was assessed using a digital goniometer. HRV indices were recorded in three positions (supine, sitting, and standing) through a smartphone application. Several significant correlations were observed between HRV indices and neck pain disability, the helplessness factor of catastrophizing, neck rotation, and quality of life. These correlations were only observed in the standing position. Pain catastrophizing was positively correlated with disability and pain intensity during active neck movement (Pearson r = 0.544, p < 0.01; Pearson r = 0.605, p < 0.01, respectively). Quality of life was negatively correlated with pain intensity during active movement (Pearson r = -0.347, p < 0.05). HRV indices were correlated with the psychological and physical domains of neck pain. These cardiac indices have been related to neck pain variables in some previous studies. Further research is needed to confirm this relationship in different daily conditions.

The effect of a neck-specific exercise program on cervical kinesthesia for patients with chronic whiplash-associated disorders: a case-control study

IntroductionCervical kinesthesia is an important part of movement control and of great importance for daily function. Previous research on kinesthesia in whiplash-associated disorders (WAD) has focused on grades I-II. More research is needed on WAD grade III. The aim of this study was to investigate cervical kinesthesia in individuals with WAD grades II-III before and after a neck-specific exercise intervention and compare them to healthy controls.MethodsA prospective, case-control study with a treatment arm (n = 30) and a healthy control arm (n = 30) was conducted in Sweden. The WAD group received a neck-specific exercise program for 12 weeks. The primary outcome to evaluate kinesthesia was neck movement control (the Fly test). Secondary outcomes were neck disability, dizziness and neck pain intensity before and after the Fly test. Outcomes were measured at baseline and post-treatment. The control arm underwent measurements at baseline except for the dizziness questionnaire. A linear mixed model was used to evaluate difference between groups (WAD and control) and over time, with difficulty level in the Fly test and gender as factors.ResultsBetween-group analysis showed statistically significant differences in three out of five kinesthetic metrics (p = 0.002 to 0.008), but not for the WAD-group follow-up versus healthy control baseline measurements. Results showed significant improvements for the WAD-group over time for three out of five kinaesthesia metrics (p < 0.001 to 0.008) and for neck disability (p < 0.001) and pain (p = 0.005), but not for dizziness (p = 0.70).ConclusionsThe exercise program shows promising results in improving kinesthesia and reducing neck pain and disability in the chronic WAD phase. Future research might benefit from focusing on adding kinesthetic exercises to the exercise protocol and evaluating its beneficial effects on dizziness or further improvement in kinesthesia.Impact statementKinesthesia can be improved in chronic WAD patients without the use of specific kinesthetic exercises.Trial registrationClinicalTrials.gov (NCT03664934), first registration approved 11/09/2018.

Occupational biopsychosocial factors associated with neck pain intensity, neck-disability, and sick leave: A cross-sectional study of construction labourers in an African population.

The burden and impact of neck pain is high in African countries including Nigeria. This study investigated the occupational biomechanical and occupational psychosocial factors associated with neck pain intensity, neck disability and sick leave amongst construction labourers in an urban Nigerian population. This cross-sectional study measured clinical neck pain outcomes, occupational biomechanical factors, and occupational psychosocial factors. Descriptive, and univariate/multivariate inferential statistical analyses were conducted. Significant independent factors associated with neck pain intensity were order and pace of tasks being dependent on others (β = 0.35; p<0.0001); inability to take breaks in addition to scheduled breaks (β = 0.25; p<0.0001); inability to work because of unexpected events (β = 0.21; p<0.0001); inability to control the order and pace of tasks (β = 0.20; p<0.0001); and weight of load (β = 0.17; p<0.0001); accounting for 53% of the variance in neck pain intensity. Significant independent factors associated with neck disability were weight of load (β = 0.30; p<0.0001); duration of load carriage (β = 0.16; p = 0.01); working under time pressure/deadlines (β = 0.16; p = 0.02); and accounting for 20% of the variance in neck disability. Significant independent factor associated with sick leave was duration of load carriage (β = 0.15; p = 0.04), in a non-significant regression model explaining -4% of the variance in sick leave. Addition of pain intensity significantly explained more variance in neck disability (31.0%) but less variance in sick leave (-5%), which was not statistically significant (F (10, 190) = 0.902, p = 0.533). Occupational biomechanical factors may be more important than occupational psychosocial factors in explaining neck disability and sick leave. In contrast, occupational psychosocial factors may be more important than occupational biomechanical factors in explaining neck pain intensity in this population in Nigeria.

Identifying Predictors of Neck Disability in Patients with Cervical Pain Using Machine Learning Algorithms: A Cross-Sectional Correlational Study.

(1) Background: Neck pain intensity, psychosocial factors, and physical function have been identified as potential predictors of neck disability. Machine learning algorithms have shown promise in classifying patients based on their neck disability status. So, the current study was conducted to identify predictors of neck disability in patients with neck pain based on clinical findings using machine learning algorithms. (2) Methods: Ninety participants with chronic neck pain took part in the study. Demographic characteristics in addition to neck pain intensity, the neck disability index, cervical spine contour, and surface electromyographic characteristics of the axioscapular muscles were measured. Participants were categorised into high disability and low disability groups based on the median value (22.2) of their neck disability index scores. Several regression and classification machine learning models were trained and assessed using a 10-fold cross-validation method; also, MANCOVA was used to compare between the two groups. (3) Results: The multilayer perceptron (MLP) revealed the highest adjusted R2 of 0.768, while linear discriminate analysis showed the highest receiver characteristic operator (ROC) area under the curve of 0.91. Pain intensity was the most important feature in both models with the highest effect size of 0.568 with p < 0.001. (4) Conclusions: The study findings provide valuable insights into pain as the most important predictor of neck disability in patients with cervical pain. Tailoring interventions based on pain can improve patient outcomes and potentially prevent or reduce neck disability.

Predicting mechanical neck pain intensity in computer professionals using machine learning: identification and correlation of key features.

Mechanical neck pain has become prevalent among computer professionals possibly because of prolonged computer use. This study aimed to investigate the relationship between neck pain intensity, anthropometric metrics, cervical range of motion, and related disabilities using advanced machine learning techniques. This study involved 75 computer professionals, comprising 27 men and 48 women, aged between 25 and 44 years, all of whom reported neck pain following extended computer sessions. The study utilized various tools, including the visual analog scale (VAS) for pain measurement, anthropometric tools for body metrics, a Universal Goniometer for cervical ROM, and the Neck Disability Index (NDI). For data analysis, the study employed SPSS (v16.0) for basic statistics and a suite of machine-learning algorithms to discern feature importance. The capability of the kNN algorithm is evaluated using its confusion matrix. The "NDI Score (%)" consistently emerged as the most significant feature across various algorithms, while metrics like age and computer usage hours varied in their rankings. Anthropometric results, such as BMI and body circumference, did not maintain consistent ranks across algorithms. The confusion matrix notably demonstrated its classification process for different VAS scores (mild, moderate, and severe). The findings indicated that 56% of the pain intensity, as measured by the VAS, could be accurately predicted by the dataset. Machine learning clarifies the system dynamics of neck pain among computer professionals and highlights the need for different algorithms to gain a comprehensive understanding. Such insights pave the way for creating tailored ergonomic solutions and health campaigns for this population.

Surgical tactics of two-segmental cervical degenerative diseases: risk factors retrospective assessment and preoperative planning.

Currently, in the specialized literature there are no substantiated clinical and radiological indications for differentiated use of anterior cervical discectomy and fusion (ACDF) and anterior cervical corpectomy and fusion (ACCF) in the treatment of patients with two-segmental cervical degenerative diseases. The objectives of this study were to (I) identify risk factors that were associated with unsatisfactory results of two-level ACDF and one-level ACCF in the treatment of patients with cervical degenerative diseases despite current perioperative management, and (II) develop a clinical and radiological algorithm for personalized surgical tactics. We retrospectively identified risk factors for the development of unsatisfactory clinical postoperative results after two-level ACDF (n=81) and one-level ACCF (n=78), operated in the period of 2009-2019 for two-segmental cervical degenerative disease. Satisfactory clinical results after two-level ACDF were noted in cases with total kyphotic deformity of less than 15°; local kyphotic deformity less than 10˚; the absence of circumferential spondylotic cervical stenosis; the absence of a myelopathic lesion at the level of the vertebral body; absence of migrating intervertebral disk (IVD) hernia more than 1/3 of the vertebral body; T1 slope vertebra less than 15°; IVD degeneration according to Suzuki A. 0-II; facet joint (FJ) degeneration according to Okamoto A. I-III; interbody height (IH) more than 2 mm. Satisfactory clinical results after single-level ACCF were registered in cases with IVD degeneration according to Suzuki A. III; FJ degeneration according to Okamoto A. IV-V; IH 3 mm or less; regardless of the cervical lordosis, the angle of local kyphotic deformity and T1 slope, the presence of circumferential spondylotic cervical stenosis, the localization of the myelopathic lesion and the distance of migration IVD herniation. Individual planning and differentiated implementation of ACDF and ACCF in patients with two-segmental cervical degenerative disease, taking into account a comprehensive preoperative clinical and radiological assessment, contributes to the effective elimination of existing neurological symptoms, reducing the intensity of neck pain and upper limbs pain, restoring the functional state and quality of patients' lives in the minimum 24 months postoperative period, as well as reducing the number of postoperative complications and reoperations.

Comparative Study of Instrument Assisted Soft Tissue Mobilization and Massage on Neck Pain

Objective: This review article aims to compare and analyse the effect of Instrument Assisted soft tissue mobilizationand massage on neck pain.Methods: This review analysed two databases i.e. (PubMed, google scholar), and extracted the studies of neckpain. Article published in the English language were included in the studies from 2016 to 2023. 10 studies wereincluded in this review. Outcome measures used neck pain intensity, and neck disability, and secondary outcomesmeasure were quality of life (QOL), neck range of motion (ROM), visual analogue scale(VAS).Result: Ten studies on 328 patients with neck pain comparing IASTM with Massage were included. Finding ofthe studies demonstrated that both IASTM and massage treatment were efficient in lowering neck discomfort andenhancing neck range of motion. IASTM showed significant improvement as compared to massage treatment interms of minimising discomfort and enhancing neck mobility.(p=0.05, p=0.001)Conclusion: It can be inferred from the comparative study of instrument-assisted soft tissue mobilisation (IASTM)and massage on neck pain that both treatments are efficient in easing discomfort and enhancing range of motion insufferers of neck pain. IASTM was significant to massage in terms of relieving pain and enhancing neck mobility.But it’s crucial to remember that each intervention has its own distinct advantages and could be a better choice forsome people depending on their requirements and preferences.
