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.

UNASSIGNED: Prolonged sitting during driving is linked to neck pain, uncomfortable body positions, and repetitive motions. Recognizing these challenges, this study aimed to investigate Cervical Health Parameters in Car Drivers.
UNASSIGNED: The sample consisted of 160 car drivers between 25 and 45 years. This subject was then divided into two groups based on neck pain. Participants met the required criteria, such as being between 25-45 years of age, maintaining a BMI of 18-24, and driving for at least 2 hours each day for at least 3-5 years. To evaluate the results, we employed a clinometer and compass app on a smartphone to measure the Cervical Range of Motion (CROM). We used Surgimap software to estimate the Craniovertebral Angle (CVA), and a (Cervical range of motion) CROM device was used for proprioception assessment.
UNASSIGNED: The result shows the participants in neck pain group displayed lower Cervical Range of Motion (CROM) values than without neck Pain Group. Similarly, the Craniovertebral Angle (CVA) was smaller in the neck Pain Group (mean difference of -6.3°), indicating a more forward head posture. Neck pain resulted in a mean difference of -4.5° in proprioception accuracy. This indicates that neck pain affects CROM, CVA, and proprioception in car drivers.
UNASSIGNED: Car driving significantly impacts cervical parameters in individuals with neck pain, reducing cervical range of motion, altered craniovertebral angle, and diminished proprioceptive accuracy. These findings emphasize the need for ergonomic interventions and proprioceptive training tailored for drivers. Future research should broaden demographic parameters and consider potential confounders to provide a holistic understanding of the relationship between car driving and neck health.

Background and Objectives: The aim of this study were to compare the cervical ROM data obtained from accelerometer exams between patients suffering from TMDs (study group) and healthy patients (control group). Material and Methods: A sample of 43 young adult subjects (23 control subjects and 20 TMD patients) were included in this study and analyzed with the accelerometer (Baiobit™, BTS, Garbagnate Milanese, Milan, Italy) to assess cervical ROM using a standardized protocol, including the following occlusal conditions: mandibular rest position, clenching, clenching with cotton rolls, maximal intercuspation, and mandibular position with cotton rolls. The cervical ROM was measured in degrees and expressed as the mean and standard deviation. Results: TMD patients showed a reduced cervical extension compared to control subjects in all the conditions, with statistically significant relevance. Regarding the other movements, the differences were not statistically or clinically significant. Conclusions: Based on the results of the present study, it can be observed that temporomandibular disorders are associated with a decreased cervical extension range, while the remaining components of ROM do not seem to be significantly associated. The use of accelerometers in ROM analysis could be helpful in improving interdisciplinary communication between dentists and physiotherapists.

BACKGROUND: The prevalence of chronic non-specific neck pain (CNNP) is on the rise among the young adult population. We herein aimed to compare the effects of long-term specific cervical extensor training and stretching exercises on improving this chronic disorder in young adults.
METHODS: In this prospective, randomized, controlled study, 70 participants aged 18-35 years with CNNP and cervical lordosis loss were included. The participants were assigned to undergo either specific cervical extensor training (observation group) or perform usual stretching exercises (control group). The exercise duration was set at 12 months, with 9 months at the clinic and 3 months at home. The outcome assessments included changes in the neck disability index, visual analog scale from baseline, cervical range of motion (CROM), cross-sectional areas (CSAs) of cervical extensors, and cervical curvature from baseline. The outcome measures were compared between groups at 3, 6, and 12 months of follow-up.
RESULTS: All 70 participants underwent randomization, and no significant differences in demographics and baseline data were found between the two groups. The observation group showed a greater improvement in neck disability index and visual analog scale scores at the 12-month follow-up than the control group. Additionally, a more substantial increase in CROM and CSAs of cervical extensors was observed in the observation group at the 6-month and 12-month follow-ups (P < 0.05). Although more participants in the observation group achieved cervical lordosis at the 12-month follow-up, the difference was marginally nonsignificant (9% in the control group vs. 28% in the observation group, P = 0.075).
CONCLUSIONS: In young adults with CNNP, long-term specific cervical extensor training was associated with a more significant clinically meaningful improvement in disability, pain, and CROM than stretching exercises. The increased CSAs of cervical extensors may potentially contribute to the restoration of cervical lordosis.

UNASSIGNED: Neck pain is a prevalent musculoskeletal issue among bike drivers, often resulting from extended static postures, repetitive head movements, and exposure to vibrations. This study aims to assess the connection between cervical ROM, neck proprioception, CVA, and QOL in bike drivers with neck pain compared to those without neck pain so that the targeted interventions can be developed to enhance their well-being.
UNASSIGNED: A cross-sectional study involving 100 bike drivers aged 20-50 years was conducted, split into two groups: those with neck pain (n=50) and those without neck pain (n=50). Cervical ROM was measured using a smartphone, neck proprioception was assessed through a head repositioning test, and CVA was determined using lateral-view photographs with a plumb line. The Short Form-36 (SF-36) questionnaire was employed to evaluate QOL. Data analysis was conducted using independent t-tests and Pearson\'s correlation coefficient.
UNASSIGNED: Bike drivers with neck pain exhibited significantly reduced cervical ROM (p-value=<0.001), impaired neck proprioception (p-value=<0.001), and decreased CVA (p-value=<0.001) compared to their counterparts without neck pain. A strong negative correlation was found between neck pain and QOL, with lower scores in all eight domains of the SF-36. Cervical ROM, neck proprioception, and CVA showed moderate correlations with various QOL domains (p-value=<0.05).
UNASSIGNED: Neck pain in bike drivers is linked to decrease cervical ROM, compromised neck proprioception, and reduced CVA. These factors correlate with a lower quality of life, both physical and mental domains. Interventions addressing these aspects may enhance the quality of life for bike drivers experiencing neck pain.

BACKGROUND: The stretching intervention of the current study was applied from several principles and the latest updated method of slowed and synchronized patterns between self-stretching with mindful breathing (MB) and eyes closed period before and after the self-stretching was performed at least four times repeatedly within 150 s per each pose.
OBJECTIVE: To investigate effects of self-stretching in five poses with and without MB on pain and cervical range of motion (CROM).
METHODS: The study was a randomized clinical trial with a blinded assessor.
METHODS: The participants were 30 females per group, aged 30-59 years with myofascial pain syndrome (MPS).
METHODS: The participants were evaluated via the pressure pain threshold (PPT) at the upper trapezius muscles and the CROM.
RESULTS: Both groups showed that the PPT at upper trapezius muscles significantly increased after performing the stretching (p < 0.001). The ROM in the MB group significantly increased in extension, left and right lateral flexion, and left rotation (p < 0.05).
CONCLUSIONS: Self-stretching with mindful breathing was designed to allow for effects within the shortest time in patients with myofascial pain syndrome. Since this treatment is a non-pharmacological intervention and was considered as part of active self-care, we suggest that this therapy could be used as alternative therapy for patients with MPS.

Neck pain, one of the most common musculoskeletal diseases, affects 222 million people worldwide. The cervical range of motion (CROM) is a tool used to assess the neck\'s state across three movement axes: flexo-extension, rotation, and lateral flexion. People with neck pain often have a reduced CROM, and they feel pain at the end-range and/or accompany neck movements with compensatory trunk movements. Virtual reality (VR) setups can track the movement of the head and other body parts in order to create the sensation of immersion in the virtual environment. Using this tracking position information, a CROM assessment can be performed using a VR setup that may be carried out autonomously from the user\'s home. The objectives of this study were to develop a VR experience that could be used to perform a CROM assessment, and to evaluate the intra-rater and inter-rater reliability of the CROM measures guided by this VR experience. To the best of our knowledge, a study of this type has not been carried out before.
A total of 30 asymptomatic adults were assessed using a VR device (HTC Vive Pro Eye™). Two raters provided support with the VR setup, and the participants were guided by the VR experience as they performed the movements. Each rater tested each subject twice, in random order. In addition to a head-mounted display (HMD), a tracker located on the subject\'s back was used to measure trunk compensatory movements. The CROM was estimated using only the HMD position and this measurement was corrected using the tracker data. The mean and standard deviation were calculated to characterize the CROM. To evaluate the reliability, the interclass correlation coefficients (ICC) were calculated for intra-rater and inter-rater analysis. The standard error of measurement and minimum detectable change were also calculated. The usability of the VR system was measured using the Spanish version of the System Usability Scale.
The mean CROM values in each axis of movement were compatible with those described in the literature. ICC values ranged between 0.86 and 0.96 in the intra-rater analysis and between 0.83 and 0.97 in the inter-rater analysis; these values were between good and excellent. When applying the correction of the trunk movements, both the intra-rater and inter-rater ICC values slightly worsened except in the case of the lateral flexion movement, where they slightly improved. The usability score of the CROM assessment/VR system was 86 points, which is an excellent usability score.
The reliability of the measurements and the usability of the system indicate that a VR setup can be used to assess CROM. The reliability of the VR setup can be affected by slippage of the HMD or tracker. Both slippage errors are additive, i.e., only when the sum of these two errors is less than the compensatory movement do the measurements improve when considering the tracker data.

Research on biomechanics in rowing has mostly focused on the lumbar spine. However, injuries can also affect other body segments. Thus, the aim of this pilot study was to explore any potential variations in the kinematics of the cervical spine during two different stroke rates on the rowing ergometer in young rowers.
Twelve young rowers of regional or national level were recruited for the study. The experimental protocol consisted of two separate test sessions (i.e., a sequence of 10 consecutive strokes for each test session) at different stroke rates (i.e., 20 and 30 strokes/min) on an indoor rowing ergometer. Kinematics of the cervical spine was assessed using an inertial sensor capable of measuring joint ROM (angle of flexion, angle of extension, total angle of flexion-extension).
Although there were no differences in the flexion and total flexion-extension movements between the test sessions, a significant increase in the extension movement was found at the highest stroke rate (p = 0.04, d = 0.66).
Young rowers showed changes in cervical ROM according to stroke rate. The lower control of the head during the rowing stroke cycle can lead to a higher compensation resulting in an augmented effort, influencing sports performance, and increasing the risk of injury.

Positional plagiocephaly (PP) is a general term describing cranial distortion from pre- or postnatal forces on the infant head. Abnormal intrauterine forces, multiple births, primiparous mothers, obstetric interventions, prematurity, male sex, excessive time lying in the supine position, and mobility restrictions of the cervical spine have been considered as the main predisposing factors. The objective was to investigate the association between the severity of PP and the active cervical rotation and to analyze the influence of predisposing factors in babies with PP. An analytical cross-sectional study was performed on 74 babies with moderate PP. Clinical and demographic data, cranial vault asymmetry, and active cervical rotation range of motion (ROM) were measured. Associations were analyzed with generalized linear models. The mean age was 16.8 ± 5.0 weeks, and 56.8% were male. A restriction in the ROM of active cervical rotation, especially to the left side, was observed. Our models showed that cranial asymmetry was related with left active cervical rotation ROM (p = 0.034) and with being transported in a pushchair (p < 0.001). Conclusions: An increased severity of PP was related with being transported in a baby pushchair and with a reduced active cervical rotation ROM toward the most restricted side.

UNASSIGNED: To investigate whether a combination of dry-needling treatments and upper extremity neuromuscular reeducation exercises can significantly improve neck pain and/or headache-related disability, joint position error, cervical range of motion, and pain pressure threshold in individuals suffering from cervicogenic headache (CGH).
UNASSIGNED: This study is a quasi-experimental design. Seven participants met the inclusion criteria and received dry needling to three muscles that reproduced the participant\'s headache symptoms and completed the Neck Disability Index (NDI), Headache Disability Inventory (HDI), Visual Analog Scale (VAS), and Numeric Pain Rating Scale (NPRS). Participants performed an exercise regimen designed to address strength and mobility of cervical and scapulothoracic musculature.
UNASSIGNED: There were significant improvements seen in cervical range of motion and neck pain-related disability (NDI) during the 4-week treatment period.
UNASSIGNED: Dry needling and neuromuscular re-education (NMR) exercises could be effective components of treatment for individuals suffering from CGH to reduce disability and pain.
